    Chevrolet Gives In, Drops the 6.2L V8 Into 2019 Suburban RST

      Finally!


    When Chevrolet unveiled the Suburban and Tahoe RST last year, the Suburban seemed to get the short end of the stick. It didn't have the option of the 6.2L V8 that was available on the Tahoe. Chevrolet is fixing that for the 2019 Suburban RST.

    Available later this summer, the RST Performance Package for the Suburban brings the 420 horsepower 6.2 V8, 10-speed automatic, and magnetic ride control. We don't have a 0-60 mph time for the Suburban, but we're expecting to be a few tenths slower than the Tahoe RST with the same powertrain. Chevrolet does say the Suburban RST with the 6.2 can tow up to 8,100 pounds.

    “The RST Performance Package made its debut on the Tahoe RST last spring, and the response from our customers was overwhelmingly positive. In fact, Tahoe RST with the Performance Package is the fastest-turning Tahoe model, and we’ve received customer requests to offer the same performance and power to Suburban RST. Delivering on those requests with the Suburban RST Performance Package is another example of how Chevrolet has continually invested in the segment, developing models with combinations of capability, technology and performance to meet the needs of different customers,” said Sandor Piszar, director of Chevy Trucks Marketing and Advertising in a statement.

    2019 SUBURBAN RST PERFORMANCE PACKAGE BRINGS V-8 POWER AND STYLE TO CHEVROLET FULL-SIZE SUVS

    DETROIT — Chevrolet today announced the new Suburban RST Performance Package. Featuring a 420-hp, 6.2L V-8 engine, Magnetic Ride Control with performance calibration and a new Hydra-Matic 10L80 10-speed automatic transmission, the Suburban RST Performance Package brings a seamless blend of style and performance to Chevy’s portfolio of full-size SUVs.

    “The RST Performance Package made its debut on the Tahoe RST last spring, and the response from our customers was overwhelmingly positive,” said Sandor Piszar, director of Chevy Trucks Marketing and Advertising. “In fact, Tahoe RST with the Performance Package is the fastest-turning Tahoe model, and we’ve received customer requests to offer the same performance and power to Suburban RST. Delivering on those requests with the Suburban RST Performance Package is another example of how Chevrolet has continually invested in the segment, developing models with combinations of capability, technology and performance to meet the needs of different customers.”

    Available later this summer, this is the first time Suburban will offer the 6.2L V-8, which boasts 420 horsepower and 460 lb-ft of torque. The engine delivers three state-of-the-art technologies — direct injection, Active Fuel Management and continuously variable valve timing — to make the most of power, torque and efficiency across a broad range of operating conditions.

    Suburban RST will also feature a new 10-speed automatic transmission. Smaller steps between each ratio maximize engine power under acceleration. With a wide 7.39 overall gear ratio spread and lower numerical top gear ratio, the transmission also reduces engine revolutions at highway speeds.

    Magnetic Ride Control is an active suspension that “reads” the road every millisecond, triggering damping changes in the electronically controlled shock absorbers in as few as 5 milliseconds. As a result, the suspension delivers both improved body-motion control during cornering and a more comfortable ride while cruising. The new performance calibration included in the Suburban RST Performance Package increases body control for even higher levels of responsiveness and comfort.

    “When you want to hustle, the Suburban RST with the Performance Package offers high levels of acceleration, braking and road-holding grip,” said Eric Stanczak, chief engineer for Chevrolet full-size trucks. “When you want to relax, it is very refined, with exceptional ride comfort and interior quietness.”

    Available performance accessories for Suburban RST include a custom tuned Performance Dual-Side Exit exhaust system designed, engineered and backed by Borla, with sleek exhaust tips that improve exhaust flow by 28 percent for enhanced performance and decreased fuel consumption. Borla, and not GM, is responsible for the safety, quality and warranty for this exhaust system.  An available performance brake package designed, engineered and backed by Brembo features massive front red six-piston, fixed aluminum calipers with brake pads clamping on larger-than-stock 410 x 32mm (16.1 inch x 1.3 inch) Duralife™ rotors coupled with an 84 percent increase in brake pad area and a 42 percent increase in rotor area to increase system thermal capacity. Duralife™ rotors feature a hardened surface to reduce corrosion.

    The Performance Package is available as an upgrade to the Suburban RST, which was introduced last year. Styling is based largely on trends in the aftermarket space — virtually all chrome trim has been eliminated for a sporty, street appearance. Changes include body-color grille surround and door handles; gloss-black grille and mirror caps; and black roof rails, window trim, badging and Chevy bowties. RST package also includes 22-inch wheels wrapped in Bridgestone P285/45R 22 tires.

    The Suburban RST is expected to boast a towing capacity of 8,100 pounds. Full performance metrics will be announced closer to launch.

    Chevrolet has been the best-selling full-size SUV brand for 43 consecutive years. Today, Tahoe is the top selling vehicle in the segment, and Tahoe and Suburban account for nearly one out of every two Full-Size SUV sales when combined. Tahoe and Suburban customers are also the most loyal owners in the segment, with 77 percent of owners replacing their full-size SUV with another Tahoe or Suburban.

    So this is the Escalade power train in a sport package. I dig it. Not everyone needs the lux of Cadillac but would still like the performance.

    This may become a modern classic. With the next generation of big SUVs so close at hand, this is a 2 year model a best on this platform. The take rate will likely be low.

    Encouraging that it is the fastest-turning Tahoe model... yes the RST is a small percentage of production, but it does not sit on the lot very long.

    They should put a Corvette ZR1 engine in the Suburban to challenge the future Demon Grand Wagoneer full size 800 hp Jeep. And it should come with 2nd and 3rd row seat delete to save weight.

    Too bad they didn't call this trim level 'SS'. 

    Good thing they did not name this trim level SS.  That belongs on high-performance cars (e.g. Camaro and Corvette) --- not a BOF SUV.  Ever.

    NO.  Just NO.  Bad idea period.  It is a rebodied truck, not a street-legal race car.

    Nonsense.  It's been used on the Silverado and TrailBlazer, and what do you think the older SS Impalas, Chevelles, and Monte Carlos were--BOF design.

    Being BOF or UB is immaterial here, despite it's mention above. A "Silverado SS" with a 6.2L is not going to be in the same high performance ballpark as a Camaro SS.

    IMO, the SS nameplate should be kept to truly well-rounded Hi-Po vehicles (this, despite the fact that the first SS was merely a trim package and could be had as an anemic I6).

    We've become pretty jaded if a 420hp V8 doesn't constitute high performance...

    They should..and in the Tahoe also.  FCA has the GC SRT and Trackhawk, and Durango SRT.   GM needs to have more high performance SUVs.  And an Escalade V-series.

    The RST performance package adds $5,400 to the price of a Premier trim Tahoe, bringing the base price of a Tahoe RST 4x4 to $70k

    Assuming similar package prices for the Suburban, that puts the base price for a Suburban RST 4x4 at minimum $73,595.

    And if we wander over to the GMC page and take a look at a Yukon XL Denali 4x4 which has essentially the same hardware......

    Screenshot_20180505-222609.png

     

    So the RST is just Chevy's version of Denali with more of a sport flare than a luxury flare. I think it's a good move and helps differentiate the brands. I won't be surprised if RST expands similarly to every Chevy that has a Denali trim on the GMC version.

    I like that idea as well but what do they do with things that already have the same engine, which is pretty much everything else?

    On the Traverse, they're doing the 2.0T, but no AWD.... not sure what the logic is on that one. Still, they're only calling it an RS rather than RST.  I have a Cruze RS Hatchback this week as a press car and it looks really good.

    They could offer sport RST packages of the Blazer and Equinox by giving them a mild turbo tune and magnride.  I'm not sure what they'd do for Colorado. They already do the Trail Boss package there.

    IF GM cannot seem to read the bones, crystal ball or what ever else you need to call it, then they need to wake up as Performance in SUVs needs to happen across all lines. GMC needs to bring back a Syclone AWD Truck and Typhoon AWD SUV just as Chevy has the RST line. Cadillac needs a V edition of the Escalade and XT line as does Buick need a Grand National or GS edition of their CUVs.

    These all need to be TRUE Performance not just badging.

      2020 CHEVROLET SILVERADO’S NEW, ADVANCED 3.0L DURAMAX TURBO-DIESEL REDEFINES EXPECTATIONS
      No-compromise engine delivers refinement, performance and efficiency
      2019-06-03
      DETROIT — The all-new 2020 Chevrolet Silverado’s available 3.0L Duramax inline-six turbo-diesel engine adds choice and versatility for full-size truck customers, offering class-leading torque and horsepower in addition to focusing on fuel economy and capability. It is the first-ever inline-six turbo-diesel offered in Chevrolet’s full-size light-duty trucks.
      Chevrolet engineers started with a clean-sheet design and developed an all-new engine that leverages the efficiency and refinement advantages of the inline six-cylinder architecture and incorporates advanced combustion and emissions technologies to optimize performance and efficiency. It is priced identically to the 6.2L V-8 as a $2,495 premium over a 5.3L V-8 model or $3,890 over a 2.7L Turbo model.
      “From the moment the engine is started, to its idle, acceleration and highway cruising, the 3.0L Duramax performance will change perceptions of what a diesel engine can offer in refinement,” said Nicola Menarini, director for Diesel Truck Engine Program Execution. “With advanced technologies that draw on global diesel expertise, it’s a no-compromise choice for those who want the capability and driving range of a diesel in a light-duty truck.”
      Available on LT, RST, LTZ and High Country models, the 3.0L Duramax diesel rounds out the new Silverado’s range of six propulsion choices, each tailored to suit customers’ needs for performance, efficiency, technology and value. It is rated at an SAE-certified 277 horsepower and 460 lb-ft of torque delivering 95 percent of peak torque at just 1,250 rpm. Peak torque is sustained from 1,500 rpm through 3,000 rpm, providing a powerfully smooth and satisfying driving experience.
      The 3.0L Duramax is paired with GM’s 10L80 10-speed automatic transmission, featuring a centrifugal pendulum absorber torque converter that reduces vibrations to improve smoothness, reinforcing its performance, efficiency and refinement. This combination also offers exhaust braking, which uses the diesel engine’s compression to help slow the vehicle, requiring fewer brake applications by the driver when in Tow Haul mode.
      Innovative Engine Technologies
      The inline six-cylinder architecture offers inherent efficiency and refinement, but the team expanded with smart technology choices to help improve efficiency and weight while optimizing the truck experience. A lightweight aluminum block and cylinder head reduce overall mass, and Active Thermal Management enhances efficiency and cold-weather warm-up. Ceramic glow plugs also help with shorter heat-up times and a quicker cold start, meaning the engine block heater is not needed until -22 degrees F.
      Towing is an important part of owning a truck, and customers can gain additional confidence thanks to the exhaust brake available in tow-haul mode. The water charge air cooler, coupled with low pressure EGR, reduces time to torque. The variable geometry turbocharger helps provide a greater balance of performance and efficiency, and an electronically variable intake manifold helps optimize performance across the rpm band.
      Inherently efficient and balanced
      Compared to a DOHC V-6, the inline-six architecture offers greater efficiency from the reduced friction of operating only two camshafts and their associated valvetrain components. The I6 configuration offers the perfect balance of primary and secondary forces, without the need for balancing shafts.
      “In addition to reduced friction, the architecture enables smooth operation,” Menarini said. “The new Duramax 3.0L elevates the 2019 Silverado with one of the most refined and efficient diesel engines in the segment.”
      Along with supporting elements such as a tuned air induction system and other noise-attenuating elements, the 3.0L Duramax delivers exceptional quietness and smoothness at all engine speeds.
      All-aluminum construction and tough rotating assembly
      The 3.0L Duramax cylinder block is made of a cast aluminum alloy that provides the strength required to support the high combustion pressures that occur within a diesel engine, while also offering an approximately 25 percent mass savings over a comparable cast iron engine block. Iron cylinder liners are used within the aluminum block to insure truck durability.
      There are seven nodular iron main bearing caps that help ensure the block’s strength under those high combustion pressures, while also enabling accurate location of the rotating assembly. A deep-skirt block design, where the block casting extends below the crankshaft centerline, also contributes to the engine’s stiffness and refinement. It’s complemented by a stiffness-enhancing aluminum lower crankcase extension attached to the main bearing caps.
      The rotating assembly consists of a forged steel crankshaft, forged steel connecting rods and hypereutectic aluminum pistons. The alloys in the respective castings for the rods and pistons make them lightweight and durable. Silicon is blended with the aluminum for heat resistance and tolerance within the piston cylinders, which enhances performance and makes the engine quiet.
      A thick piston crown — the top of the piston — and reinforced top ring add strength to support the tremendous cylinder pressures enabled by turbocharging and the engine’s high 15.0:1 compression ratio.
      DOHC Cylinder Head and Rear Cam Drive
      Overhead camshafts offer a direct, efficient means of operating the valves, while four valves per cylinder activated by maintenance-free finger followers with hydraulic lash adjusters increase airflow in and out of the engine. This arrangement is integrated on the Duramax 3.0L’s lightweight aluminum cylinder head, which is topped with a lightweight composite cam cover that incorporates the crankcase ventilation and oil separation systems.
      A pair of lightweight, assembled camshafts actuates 28.35 mm diameter (1.12-inch) intake and 24.55 mm diameter (0.97-inch) exhaust valves. The camshaft drivetrain is uniquely located at the rear (flywheel side) of the engine, for greater refinement and packaging considerations for the comparatively long inline-six. A crankshaft-driven chain drives the high-pressure direct-injection fuel pump, while a chain driven by the fuel pump drives both intake and exhaust camshafts. A smaller belt drives the variable flow oil pump from the crankshaft.
      Additional Technology Highlights
      Variable geometry turbocharging enables the Duramax 3.0L engine to deliver class-leading horsepower with minimal effect on overall efficiency. The system uses closed loop controlled vanes position and sophisticated electronic controls to automatically adjust boost pressure to the desired value based on engine running conditions and instantaneous power demand. The liquid-cooled turbocharger features a low-friction ball-bearing shaft and is mounted close to the exhaust outlet of the engine for quicker spool-up of the turbine and quicker light-off of the exhaust catalyst. A water-to-air intercooling system produces a cooler higher density air charge for greater power. Maximum boost pressure is 43,5 psi (300 Kpa) absolute.
      Low-pressure EGR: The Duramax 3.0L utilizes new low-pressure Exhaust Gas Recirculation to optimize performance and efficiency. The EGR system diverts some of the engine-out exhaust gas and mixes it back into the fresh intake air stream, which is drawn into the cylinder head for combustion. That lowers combustion temperatures and rates.
      Traditionally, EGR systems in diesel applications recirculate exhaust gases between the two high-pressure points, the exhaust manifold(s) and intake manifold. However, it generally requires efficiency-robbing assistance from the turbocharger or other supporting elements to achieve the pressure differential required for sufficient EGR flow rates.
      The new low-pressure system adds to the high-pressure system, supporting continual adjustment of exhaust backpressure for more efficient operation. It recirculates gases between the low-pressure points in the exhaust system (downstream of the particulate filter) and after the compressor inlet.
      When the low-pressure EGR is activated by an electronically controlled valve, the engine burns exhaust gas that has already passed through the particulate filter. That increases the turbocharger’s efficiency, which helps overall vehicle efficiency without deteriorating the rate of particulate matter emitted by the engine.
      A variable intake manifold offers dual air intake pathways for each cylinder. Electronically controlled flaps — one for each cylinder — shorten or lengthen the airflow to each cylinder. This optimizes the airflow into the engine and improves performance and responsiveness across the rpm band, particularly at lower engine speeds.
      A variable-pressure oiling system with a continuously variable-displacement vane oil pump enhances efficiency by optimizing oil pressure as a function of engine speed and load. With it, the oil supply is matched to the engine requirements rather than the excessive supply of a conventional, fixed-displacement oil pump. The engine uses low-friction Diesel Dexos 0W20 oil.
      Oil jets located in the block are employed for performance and temperature control. They target the inner core of the piston with an extra layer of cooling, friction-reducing oil. The jets reduce piston temperature, allowing the engine to produce more power and enhance long-term durability than engines without the technology.
      Active Thermal Management helps the engine warm up quickly to achieve and maintain its optimal engine temperature for performance and efficiency over the entire engine operating range. The system uses a three-actuator rotary valve system to distribute coolant through the engine in a targeted manner. It sends heat where it’s needed to warm up the engine to reduce friction and heat the passenger cabin or cools when needed for high-power operation. The Duramax 3.0L also features split cooling between the block and head.
      Common rail direct fuel injection of 2,500 bar (36,250 psi) helps generates class-leading horsepower and torque. The system’s pressure is generated by an engine-driven twin-piston pump sending fuel to solenoid-activated injectors with nine-hole nozzles that support precise metering of the fuel for a smooth idle and lower combustion noise. The fuel system is capable of multiple injections per combustion cycle — up to 10 times per injector — for more consistent and stable combustion performance that translates into smoothness and refinement, particularly at idle.   
      Electronic throttle valve: The Duramax 3.0L features an electronic throttle valve to regulate intake manifold pressure in order to optimize exhaust gas recirculation rates. It also contributes to a smooth engine shutdown via a more controlled method of airflow reduction.
      Ceramic glow plugs used in the Duramax 3.0L heat up more quickly and hotter than conventional metal-based glow plugs, helping the engine start and heat up more quickly in cold weather. The Duramax 3.0L achieves unassisted and assisted starting temperatures of -22 F (-30 C) and -40 F (-40 C) respectively.
      Stop/start technology helps optimize efficiency in city driving. The driver-selectable system shuts off the engine at stoplights and other stop-and-go situations. The engine automatically restarts when the driver takes their foot off the brake.

      2020 CHEVROLET SILVERADO’S NEW, ADVANCED 3.0L DURAMAX TURBO-DIESEL REDEFINES EXPECTATIONS
      No-compromise engine delivers refinement, performance and efficiency
      2019-06-03
      DETROIT — The all-new 2020 Chevrolet Silverado’s available 3.0L Duramax inline-six turbo-diesel engine adds choice and versatility for full-size truck customers, offering class-leading torque and horsepower in addition to focusing on fuel economy and capability. It is the first-ever inline-six turbo-diesel offered in Chevrolet’s full-size light-duty trucks.
      Chevrolet engineers started with a clean-sheet design and developed an all-new engine that leverages the efficiency and refinement advantages of the inline six-cylinder architecture and incorporates advanced combustion and emissions technologies to optimize performance and efficiency. It is priced identically to the 6.2L V-8 as a $2,495 premium over a 5.3L V-8 model or $3,890 over a 2.7L Turbo model.
      “From the moment the engine is started, to its idle, acceleration and highway cruising, the 3.0L Duramax performance will change perceptions of what a diesel engine can offer in refinement,” said Nicola Menarini, director for Diesel Truck Engine Program Execution. “With advanced technologies that draw on global diesel expertise, it’s a no-compromise choice for those who want the capability and driving range of a diesel in a light-duty truck.”
      Available on LT, RST, LTZ and High Country models, the 3.0L Duramax diesel rounds out the new Silverado’s range of six propulsion choices, each tailored to suit customers’ needs for performance, efficiency, technology and value. It is rated at an SAE-certified 277 horsepower and 460 lb-ft of torque delivering 95 percent of peak torque at just 1,250 rpm. Peak torque is sustained from 1,500 rpm through 3,000 rpm, providing a powerfully smooth and satisfying driving experience.
      The 3.0L Duramax is paired with GM’s 10L80 10-speed automatic transmission, featuring a centrifugal pendulum absorber torque converter that reduces vibrations to improve smoothness, reinforcing its performance, efficiency and refinement. This combination also offers exhaust braking, which uses the diesel engine’s compression to help slow the vehicle, requiring fewer brake applications by the driver when in Tow Haul mode.
      Innovative Engine Technologies
      The inline six-cylinder architecture offers inherent efficiency and refinement, but the team expanded with smart technology choices to help improve efficiency and weight while optimizing the truck experience. A lightweight aluminum block and cylinder head reduce overall mass, and Active Thermal Management enhances efficiency and cold-weather warm-up. Ceramic glow plugs also help with shorter heat-up times and a quicker cold start, meaning the engine block heater is not needed until -22 degrees F.
      Towing is an important part of owning a truck, and customers can gain additional confidence thanks to the exhaust brake available in tow-haul mode. The water charge air cooler, coupled with low pressure EGR, reduces time to torque. The variable geometry turbocharger helps provide a greater balance of performance and efficiency, and an electronically variable intake manifold helps optimize performance across the rpm band.
      Inherently efficient and balanced
      Compared to a DOHC V-6, the inline-six architecture offers greater efficiency from the reduced friction of operating only two camshafts and their associated valvetrain components. The I6 configuration offers the perfect balance of primary and secondary forces, without the need for balancing shafts.
      “In addition to reduced friction, the architecture enables smooth operation,” Menarini said. “The new Duramax 3.0L elevates the 2019 Silverado with one of the most refined and efficient diesel engines in the segment.”
      Along with supporting elements such as a tuned air induction system and other noise-attenuating elements, the 3.0L Duramax delivers exceptional quietness and smoothness at all engine speeds.
      All-aluminum construction and tough rotating assembly
      The 3.0L Duramax cylinder block is made of a cast aluminum alloy that provides the strength required to support the high combustion pressures that occur within a diesel engine, while also offering an approximately 25 percent mass savings over a comparable cast iron engine block. Iron cylinder liners are used within the aluminum block to insure truck durability.
      There are seven nodular iron main bearing caps that help ensure the block’s strength under those high combustion pressures, while also enabling accurate location of the rotating assembly. A deep-skirt block design, where the block casting extends below the crankshaft centerline, also contributes to the engine’s stiffness and refinement. It’s complemented by a stiffness-enhancing aluminum lower crankcase extension attached to the main bearing caps.
      The rotating assembly consists of a forged steel crankshaft, forged steel connecting rods and hypereutectic aluminum pistons. The alloys in the respective castings for the rods and pistons make them lightweight and durable. Silicon is blended with the aluminum for heat resistance and tolerance within the piston cylinders, which enhances performance and makes the engine quiet.
      A thick piston crown — the top of the piston — and reinforced top ring add strength to support the tremendous cylinder pressures enabled by turbocharging and the engine’s high 15.0:1 compression ratio.
      DOHC Cylinder Head and Rear Cam Drive
      Overhead camshafts offer a direct, efficient means of operating the valves, while four valves per cylinder activated by maintenance-free finger followers with hydraulic lash adjusters increase airflow in and out of the engine. This arrangement is integrated on the Duramax 3.0L’s lightweight aluminum cylinder head, which is topped with a lightweight composite cam cover that incorporates the crankcase ventilation and oil separation systems.
      A pair of lightweight, assembled camshafts actuates 28.35 mm diameter (1.12-inch) intake and 24.55 mm diameter (0.97-inch) exhaust valves. The camshaft drivetrain is uniquely located at the rear (flywheel side) of the engine, for greater refinement and packaging considerations for the comparatively long inline-six. A crankshaft-driven chain drives the high-pressure direct-injection fuel pump, while a chain driven by the fuel pump drives both intake and exhaust camshafts. A smaller belt drives the variable flow oil pump from the crankshaft.
      Additional Technology Highlights
      Variable geometry turbocharging enables the Duramax 3.0L engine to deliver class-leading horsepower with minimal effect on overall efficiency. The system uses closed loop controlled vanes position and sophisticated electronic controls to automatically adjust boost pressure to the desired value based on engine running conditions and instantaneous power demand. The liquid-cooled turbocharger features a low-friction ball-bearing shaft and is mounted close to the exhaust outlet of the engine for quicker spool-up of the turbine and quicker light-off of the exhaust catalyst. A water-to-air intercooling system produces a cooler higher density air charge for greater power. Maximum boost pressure is 43,5 psi (300 Kpa) absolute.
      Low-pressure EGR: The Duramax 3.0L utilizes new low-pressure Exhaust Gas Recirculation to optimize performance and efficiency. The EGR system diverts some of the engine-out exhaust gas and mixes it back into the fresh intake air stream, which is drawn into the cylinder head for combustion. That lowers combustion temperatures and rates.
      Traditionally, EGR systems in diesel applications recirculate exhaust gases between the two high-pressure points, the exhaust manifold(s) and intake manifold. However, it generally requires efficiency-robbing assistance from the turbocharger or other supporting elements to achieve the pressure differential required for sufficient EGR flow rates.
      The new low-pressure system adds to the high-pressure system, supporting continual adjustment of exhaust backpressure for more efficient operation. It recirculates gases between the low-pressure points in the exhaust system (downstream of the particulate filter) and after the compressor inlet.
      When the low-pressure EGR is activated by an electronically controlled valve, the engine burns exhaust gas that has already passed through the particulate filter. That increases the turbocharger’s efficiency, which helps overall vehicle efficiency without deteriorating the rate of particulate matter emitted by the engine.
      A variable intake manifold offers dual air intake pathways for each cylinder. Electronically controlled flaps — one for each cylinder — shorten or lengthen the airflow to each cylinder. This optimizes the airflow into the engine and improves performance and responsiveness across the rpm band, particularly at lower engine speeds.
      A variable-pressure oiling system with a continuously variable-displacement vane oil pump enhances efficiency by optimizing oil pressure as a function of engine speed and load. With it, the oil supply is matched to the engine requirements rather than the excessive supply of a conventional, fixed-displacement oil pump. The engine uses low-friction Diesel Dexos 0W20 oil.
      Oil jets located in the block are employed for performance and temperature control. They target the inner core of the piston with an extra layer of cooling, friction-reducing oil. The jets reduce piston temperature, allowing the engine to produce more power and enhance long-term durability than engines without the technology.
      Active Thermal Management helps the engine warm up quickly to achieve and maintain its optimal engine temperature for performance and efficiency over the entire engine operating range. The system uses a three-actuator rotary valve system to distribute coolant through the engine in a targeted manner. It sends heat where it’s needed to warm up the engine to reduce friction and heat the passenger cabin or cools when needed for high-power operation. The Duramax 3.0L also features split cooling between the block and head.
      Common rail direct fuel injection of 2,500 bar (36,250 psi) helps generates class-leading horsepower and torque. The system’s pressure is generated by an engine-driven twin-piston pump sending fuel to solenoid-activated injectors with nine-hole nozzles that support precise metering of the fuel for a smooth idle and lower combustion noise. The fuel system is capable of multiple injections per combustion cycle — up to 10 times per injector — for more consistent and stable combustion performance that translates into smoothness and refinement, particularly at idle.   
      Electronic throttle valve: The Duramax 3.0L features an electronic throttle valve to regulate intake manifold pressure in order to optimize exhaust gas recirculation rates. It also contributes to a smooth engine shutdown via a more controlled method of airflow reduction.
      Ceramic glow plugs used in the Duramax 3.0L heat up more quickly and hotter than conventional metal-based glow plugs, helping the engine start and heat up more quickly in cold weather. The Duramax 3.0L achieves unassisted and assisted starting temperatures of -22 F (-30 C) and -40 F (-40 C) respectively.
      Stop/start technology helps optimize efficiency in city driving. The driver-selectable system shuts off the engine at stoplights and other stop-and-go situations. The engine automatically restarts when the driver takes their foot off the brake.

      GM is delaying the launch of the new inline-6 diesel engine bound for the GMC Sierra 1500 and Chevrolet Silverado 1500.  No longer available for ordering on the 2019s, GM has pushed the availability into the 2020 model year. 
      According the GM, the emissions certification process on the engine is taking longer than normal.   Customers who ordered a 2019 Silverado or Sierra with the diesel engine will have their orders canceled and will need to resubmit the order for a 2020 model year vehicle once they become available for order.  GM has yet to open orders for 2020 truck models with the diesel engine, but a GM spokesperson said that it will be "soon".
      Assuming the current pricing holds, the 3.0 liter Duramax diesel will be priced $2,495 over a 5.3 liter V8 and $2,890 over the 4-cylinder 2.7-liter turbo. 
      Meanwhile for 2020, GM is expanding the availability of adaptive cruise control and the 10-speed automatic across the lineup.  At Chevy, the Silverado will now have the optional 6.2 liter V8 on five out of the eight trim levels.  The 6.2 V8 will be paired with the 10-speed automatic and available on the Custom Trail Boss, RST, LT Trail Box, LTZ, and High Country. At GMC, the CarbonPro box will be available at no additional cost when paired with certain other packages on the Sierra AT4 and Sierra Denali, while the double cab Sierra Elevation Trim will now also be available in a crew cab.
