Chevrolet News:Chevrolet Debuts 2021 Trailblazer

Recommended Posts

Chevy unveiled the 2021 Trailblazer today, filling a space between the Chevrolet Trax and Equinox in the lineup.  This follows the recent release of the Buick Encore GX that fills a similar but more premium space. 

Picking up on styling from the larger Blazer and the Camaro, the Trailblazer takes an aggressive, sporty posture. Yes, there also will be an RS version, but no word yet on what powertrains will be available. 

Chevy is finally going to start offering active safety features as standard, something the competition started doing a few years ago. The standard active safety features are Front Pedestrian Braking, Automatic Emergency Braking and Lane Keep Assist with Lane Departure Warning.  Optional will be Adaptive Cruise Control - Camera, Rear Park Assist and a High Definition Rear Vision Camera.

The 2021 Trailblazer will enter dealerships in early 2020.

Really GM? Can’t save that name for a RWD SUV? 

 

At at least Ford had good sense to put the Explorer back on a RWD platform and will do the same with the Bronco. 

 

For the record, this is not a knock on the CUV itself. It’s just the wrong name for it. The profile does scream Nissan Kicks though. Not sure that’s a good thing.

It looks like a Volvo XC40 or that little Hyundai, I am over the "floating roof" already.  Otherwise it looks fine, looks like a Blazer/Camaro for less money, looks much better than a Traxx.

To me "Trailblazer" is better than "Blazer" so I don't know why they wasted the Trailblazer name here.  Probably should have called this the Tracker.

Tracker would have been a far better name for this CUV but with the name “Trax” already taken, it may create some confusion for some folks. Still better than “Trailblazer”.

I do not care what it's called, I think it's a sweet little machine for everyday usage, with a little pizazz thrown in.  I just hope they have a nicer variety of colors available v. the Blazer.

Since Chevy is pitching the Blazer as "the Camaro of SUVs", I think they should have the same colors available on both vehicles.  That would be a strong but subtle way to tie them together... and it might lead to households buying "his & hers" Blazer and Camaro in matching colors.

I would say almost certainly a new Trax is coming if a new Encore is coming (which we know the second part is true)

Weird to me that they are calling the shorter (of the two small Buicks shown in China) Buick the Encore GX in America and saying it will not replace the Encore...  They are doing the same with the Chevys.  Both Buick and Chevrolet have shown longer versions of these with moderately different styling and entirely different names in Chevy's case (Tracker and Trailblazer).

I don't think they are worried about confusion when they have the Encore and Encore GX as 2 difference vehicles.  I would have used Tracker here.  Saved Trailblazer for a Jeep Wrangler/Ford Bronco competitor.

I too agree there is confusion or weirdness calling this ‘trailblazer’ but make no mistake this makes sense to offer this line here. It means they can keep selling the trax at cheaper prices and it remains the de facto small Chevy. Essentially the trax fills the sonic / Cruze void. The equinox will need to upsize a bit and even after only two years is already tired in the market. The Hyundai kona is storming the market so trailblazer is wanting in on this emerging niche. The compact class like equinox and RAV4 is probably getting too expensive for first time buyers so this makes sense to add this in between for those that think trax is too small.

Was hoping for a cool off-road version of the Blazer.

So, this is kinda like a Trax with a real “trunk”?

I have zero issue with them reusing the name but it's awkward on the size of vehicle they chose to use for it...

I almost feel like they should have done what Ford is doing with the next Escape/Baby Bronco and the Trailblazer name should be used on an off-road version of the Equinox or Blazer. Yeah, FWD based.. but they could make it work if they made it its own model. If Jeep can make off-roady FWD CUVs, GM can as well. 

I mean the name "Trail-Blazer" doesn't sound like the name of a Camaro-inspired, FWD CUV with 4 inches of ground clearance and no form of locking differentials(I know that wasn't stated but let's be honest...)

Tracker would have been an appropriate name for this, save the Trailblazer for something more trail worthy.

It is confusing if you recall how Chevy's midsize SUVs were 15 years ago--the Blazer was the small-midsize S10 based SUV, and the TrailBlazer was the larger midsize GMT360 SUV.   Now Blazer is a larger CUV than the TrailBlazer.   Makes no sense, IMO.  Tracker would have been a better name for this.

To all the folk complaining about the name of this little new CUV.

Ya'll preferred if it was called the Chevrolet  ZX71?

Just be glad it has an honest to goodness WORD as a name.  

As long as its a word or noun or verb that we can find in any language DICTIONARY...we good, dudes!!!

But that is this reality that we have come to witness in 2019. Bemoan an actual word as a name for a vehicle when alphanumerics have drowned us, but dont bitch about yet another deadly disease to inflict humanity in the form yet another :censored:  crossover.

Well the vehicle itself is just another decent small CUV in a market full of them, not interesting, nothing to set it apart.  The choice of model name is a more interesting topic of discussion :).

OK...Ill play this game...

I get it.  Nobody LUVs this name. Chevrolet did not EXPRESS  the proper name structure for it.  It has the wrong SPARK with some of you. It feels like a KODIAK eating you alive  eh? Its like a TOP KICK to the balls, right?

It seems Chevrolet VENTURE(D) and TRAVERSE(D) into an AVALANCHE of dog poop.  What can we do?  Give Chevrolet a CITATION of some sort?  What would that accomplish?  I know, it does not CAPTIVA(TE) the essence of Chevy's history.  

I get your passion for the name structure. You folk refuse to take a CAVALIER approach to all of this. Ya'll should form a TASK FORCE,  take a  BERETTA  to it  and put it out of its misery. Then take all its parts and ship them  back all over the work, to ORLANDO, COLORADO, MALIBU, BEL AIR, MONTE CARLO, CORSICA so we never LUMINA(TE) this garbage ever again.    Post your ENDEAVORS (wrong brand) on Facebook or Instagram in a way that rivals a NOVA and become instant CELEBRIT(Y)IES... 

But alas.  There is no SILVER(ADO)  linen in this cloud of yours... but a new EQUINOX shall arrive anyway, and its written in COBALT, that this new SUPER SPORT(Y) CUV will forever be known in this EL CAMINO world, that this CUV will forever be known as the TRAILBLAZER!!!!

Tracker would have made the most sense, as they previously in the US had a subcompact CUV named Tracker.   TrailBlazer has only previously been used on midsize BOF SUVs, so this is an inappropriate usage of a past name.     But the mindless masses that buy such CUVs won't notice or care, so it's a moot point.

      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.

      Chevy unveiled the 2021 Trailblazer today, filling a space between the Chevrolet Trax and Equinox in the lineup.  This follows the recent release of the Buick Encore GX that fills a similar but more premium space. 
      Picking up on styling from the larger Blazer and the Camaro, the Trailblazer takes an aggressive, sporty posture. Yes, there also will be an RS version, but no word yet on what powertrains will be available. 
      Chevy is finally going to start offering active safety features as standard, something the competition started doing a few years ago. The standard active safety features are Front Pedestrian Braking, Automatic Emergency Braking and Lane Keep Assist with Lane Departure Warning.  Optional will be Adaptive Cruise Control - Camera, Rear Park Assist and a High Definition Rear Vision Camera.
      The 2021 Trailblazer will enter dealerships in early 2020.
