According to GM Authority, the Chevrolet Traverse is dropping the 2.0T from the lineup and is already no longer available for ordering. The move means that the only available powertrain for the Traverse is the 310 horsepower V6 paired with a 9-speed automatic. The 2.0T was introduced in the 2018 model year only on the RS model which had a slightly sportier flair than the regular Traverse. We wonder though if this signals a move by Chevy to use the new TriPower 2.0T that is found in the Cadillac XT4 and was recently announced to be going into the 2020 GMC Acadia. So don't be surprised if there is an announcement from Chevy soon. View full article

Since the launch of the XT4 with the rather anemic (if more refined) LSY engine, many (including myself) had questioned why GM does not offer the Tripower 310 bhp / 348 lb-ft (L3B) 2.7T 4-cylinder in the XT4 (at least) as an option. To a lesser extent some have also questioned why the LSY is putting out a mere 237bhp / 258 lb-ft whereas the outgoing LTG engine is good for 265~272 bhp / 295 lb-ft. Is it just so that it can have 258 lb-ft arrive @ 1,500 rpm? Now, we have the answer... It's the 9-speed Automatics. Adopting the 9-speed automatics is deemed a priority for refinement and fuel economy. The new GM-Ford 9TXX transmissions, jointly developed with Ford promises better fuel economy and better shift quality. There are currently two versions of this transmission:- 9T50 -- 258 lb-ft 9T65 -- 280 lb-ft The need to pack 9-speeds into a very slim transmission case meant that they have to use an ovoid cross section torque converter, a tension chain coupling and abandon the high torque capability of the previous generation top dog 6T80 (369 lb-ft) transmissions used in the 410 hp / 368 lb-ft 3.6L Twin-Turbo (LF3) powered Cadillac XTS. The lack of torque capability is also in part why Ford abandoned the use of the GM-Ford 9TXX transmissions, choosing instead to develop an 8-speed evolution of the decade old 6T80 for use in their high torque applications like the Ford Edge ST (2.7L Ecoboost V6 with 335 hp / 380 lb-ft). Ford also asserts that the new 9-speed autos did not yield any fuel economy improvement when tested with their engines and the refinement improvements alone did not justify the costs and weight increases.

The folks over at Hagerty found something interesting on the NHTSA website the other day, a VIN decoder ring that shows a second 2.3 liter 4-cylinder turbo with a horsepower rating of TBD. Ford dropped the V6 in the base Mustang after 2018 deciding the Turbo-4 was enough, but crosstown rival Chevy kept their V6 going alongside their 275 horsepower 2.0T. While Ford's 2.3T beats the Chevy Turbo in power, it comes up short against Chevy's V6. With this finding, it looks like Ford is going try to rectify the deficit. Given that a similar 2.3T is good for 350 hp in the Focus RS, Ford should be able to easily surpass the 335 horsepower the Camaro V6 produces. A statement from a Ford representative declined to give details but said that we would have exciting news about Mustang in Spring 2019. View full article

A user on Reddit posted today an image showing an internal document from Mazda Canada detailing some of changes coming to the 2019 CX-5. The highlights mention that the CX-5 will be getting the turbocharged 2.5L four-cylinder from the CX-9, G-Vectoring Control Plus (we're assuming this is updated version of the system); changes to the exterior, the top-line Signature trim becoming available, and compatibility with Apple CarPlay and Android Auto. The mention of the turbo engine confirms a CAFE document we reported back in June listing the 2019 CX-5 with the turbo engine. If you're wondering about the trims, that's for Mazdas sold in Canada - they won't changing the trim line that significantly for the U.S. at this moment. Source: Reddit View full article

When we drove the Mazda CX-5 towards the end of last year, we found ourselves wishing that either the long-delayed turbodiesel or possibly the 2.5: turbo-four from the CX-9 would grace the engine. The 2.5L four-cylinder does ok around town, but really struggles when more speed is needed. It seems our wish could be coming true. The Truth About Cars obtained a certification document from the California Air Resources Board for the turbocharged 2.5L four-cylinder. In the document, it lists the 2019 CX-9 and CX-5 offering this engine. It would give the CX-5 a nice power boost as the turbo-four produces 227 horsepower (250 horsepower on premium fuel) and 310 pound-feet of torque. Mazda declined to comment when asked about the document. We're guessing that Mazda could debut the turbo engine in the CX-5 at the LA Auto Show in November.

When Jeep released the 2014 Cherokee, much of the automotive press panned its polarising appearance. However, the buying public disagreed and went on to buy 220k Jeep Cherokees in 2015, its second full year on sale. For 2019, Jeep is updating the Cherokee to soften those polarizing looks and bring some new refinements to the Cherokee brand. First up is the front facia; The headlight clusters have been moved higher, up and out of the bumper and into a more conventional location in the upper fenders. The pointy grille has also been softened into a more versatile piece. Around back, the liftgate has new contouring in contrast to the giant flat surface of the outgoing model. The tail lights have been revised as well. The interior of the Cherokee largely carries over with just some minor repositioning of the USB outlets. Jeep did manage to find another 3 inches of width in the rear cargo area bringing the total to over 27 cubic feet. Jeep's UConnect system has been updated to the latest version and now includes Apple CarPlay and Android Auto. As for motivation, the two existing power trains carry over and a new one joins the lineup. The 2.4 liter Tigershark multi-air produces 180 horsepower and 170 lb-ft of torque. Jeep changed some components out for less weight and less NVH. Customers can also select the 3.2 liter Pentastar V6 with 271 horsepower and 231 lb-ft of torque. This engine gives the Cherokee a best in class tow rating of 4,500 lbs. Both engines include electronic start-stop for improved fuel economy around town. New for 2019 is a 2.0 liter turbo direct-injected 4-cylinder that first debuted in the 2018 Jeep Wrangler at the 2017 Los Angeles Auto Show. In the Cherokee, the 2.0T is rated for 270 horsepower and 295 lb-ft of torque and also features electronic start-stop. The engine features a twin scroll turbo with an electronically activated wastegate. Jeep saved 3 1/2 lbs of weight from the engine by using hollow camshafts. All three of these engines are fitted to a 9-speed automatic transmission that has received additional software updates for 2019. Naturally it would not be a Jeep without available off-road capability. The three 4x4 systems from the previous model carry over. The 2019 Jeep Cherokee will arrive at dealers in early 2018.

New 2.0-liter direct injection turbocharged inline four-cylinder engine with engine stop-start (ESS) The 2019 Jeep Cherokee offers a practical and dependable choice for everyday adventures with premium on-road manners and impressive fuel efficiency – courtesy of three engine offerings. One of the most technologically advanced engines in the automotive industry, the all-new 2.0-liter direct injection turbocharged inline four-cylinder engine is rated at 270 horsepower and 295 lb.-ft. of torque and is mated to a high-efficient nine-speed automatic transmission. Benefits of the new engine include outstanding fuel economy with engine stop-start (ESS) technology, low emissions, quick 0-60 miles per hour (mph) launch performance, and enhanced drivability. The all-new 2.0-liter I-4 features a twin-scroll, low inertia turbocharger with an electric actuated waste gate for exceptional responsiveness and performance, even while traversing over difficult terrain. The turbo is mounted directly to the cylinder head to reduce emissions and improve durability. A dedicated cooling circuit lowers the temperature of the intake air, throttle body and turbocharger. The 2.0-liter turbocharged I-4 engine is part of the Global Medium Engine architecture family and features double overhead camshafts (DOHC), dual independent camshaft timing, and a cooled exhaust gas recirculation (C-EGR) system. This is the first time that the combined use of a twin-scroll turbocharger, C-EGR system, central direct injection and the independent liquid cooling intake of air, throttle body and turbo have been employed together. This combination of technologies enables the high levels of performance and reduces fuel consumption. Direct injection, coupled with turbocharging, enables more efficient combustion, reduced emissions and increased performance. The 2.0-liter I-4 engine’s fuel pump supplies the engine’s 2,900-psi high-pressure common-rail injection system. These high pressures produce better fuel atomization and allow for more precise fuel delivery than port fuel-injected systems, which in turn improves both performance and efficiency. The cast aluminum alloy cylinder head features a central injector and high tumble intake ports. This combination provides high charge motion and balanced air flow to improve fuel efficiency and performance. Integrated into the cylinder head is a water-cooled exhaust manifold to reduce emissions while providing increased engine reliability. The 2.0-liter I-4 engine features a low-pressure, sand cast-aluminum block with cast-in iron liner with an 84mm bore and 90mm stroke for a total displacement of 1,995cc. Cast-aluminum pistons, with a 10:1 compression ratio, have four valve pockets to accommodate the dual variable-valve timing [VVT] system. Each cylinder bore is fitted with gallery-mounted piston oil cooling jets to limit piston temperatures, reduce spark knock and increase piston durability. Select-fit main and rod bearings enable reduced clearances to help lower system oil demand and oil pumping effort. In addition, floating piston pins utilize diamond-like coating (DLC) for reduced friction. The high-energy ignition system includes a high-energy ignition coil for better fuel efficiency. Precious-metal spark plugs with iridium and platinum provide lasting durability. Located in the center of the cam cover, the spark plugs are easily accessible when service is required. Sodium-filled exhaust valves and plasma-coated piston rings also help extend the engine’s life and bolster durability. A variable displacement two-stage oil pump provides high oil pressure under high speed but switches to a low-pressure mode for improved fuel economy during typical driving conditions. The piston cooling is also managed by the two-stage oil pump to enhance fuel economy under normal driving conditions while improving durability under demanding, high-load engine operation. A large capacity oil cooler extends the oil change interval and ensures engine durability. An inverted tooth primary chain drives both the intake and exhaust camshafts and minimizes noise. Camshafts are robotically assembled using hollow shafts and have polished cam journals to reduce weight and improve durability for engine stop-start operation. The use of hollow shafts provides a 3.5-lb. weight reduction when compared to an equivalent solid shaft. High-efficient powertrains Two additional high-efficient engines options are available in the 2019 Jeep Cherokee: the 3.2-liter Pentastar V-6 and 2.4-liter PZEV Multiair2 Tigershark I-4 – both mated to a nine-speed automatic transmission. 3.2-liter Pentastar V-6 The 3.2-liter Pentastar V-6 engine is available across the Cherokee lineup producing 271 horsepower, 239 lb.-ft. of torque and delivering best-in-class V-6 towing of 4,500 pounds. The engine blends a balance of efficiency, power and refinement from the same innovations that earned its larger displacement predecessor industry-wide acclaim, while reducing noise, vibration and harshness (NVH) for occupants. The engine retains its individual exhaust-manifold runners that are integrated into the aluminum cylinder-head casting and are a key Pentastar-family differentiator. This feature not only reduces weight and produces packaging benefits; it also increases manufacturing efficiency. The 24-valve engine’s 10.7:1 compression ratio aids in lowering fuel consumption and improves performance while the variable-displacement oil pump further reduces parasitic losses to maximize fuel economy. The pump is programmed to operate as needed, staying in low-pressure mode at rpms below 3,500, and then bumping up pressure as demand follows engine speed. 2.4-liter MultiAir2 Tigershark I-4 The fuel efficient and refined 2.4-liter PZEV MultiAir2 Tigershark I-4 engine is standard in the new 2019 Jeep Cherokee. The 2.4-liter MultiAir2 Tigershark I-4 engine produces 180 horsepower and 170 lb.-ft. of torque. For 2019, engine oil heater and weight-reduced components were achieved, which improved fuel economy during warm-up cycles. Also, changes to air intake applications have resulted in noise vibration and harshness (NVH) improvements. The acclaimed electro-hydraulic fully variable valve-lift system uses a column of oil in place of the traditional mechanical link between the camshaft and intake valves. It delivers precise control of the intake-valve events – beginning and end – delivering reductions in engine-pumping losses and increases in volumetric efficiency. In addition to reducing carbon-dioxide emissions, MultiAir2 accounts for a fuel-economy boost of up to 7.5 percent, compared with engines with conventional valve trains. Nine-speed transmission The 2019 Jeep Cherokee benefits from an upgraded TorqueFlite nine-speed automatic transmission. The gearbox features new software that further refines drivability. The nine-speed transmission delivers numerous benefits, including aggressive launches, smooth power delivery at highway speeds and improved fuel efficiency versus a six-speed automatic transmission. The transmission is engineered to ensure the vehicle is always in the appropriate gear. Its 4.71 first-gear ratio contributes to launch performance, while the small steps between mid-range gears ensure smoothness. Higher gears enable lower engine speeds – a primary operating condition for superior fuel efficiency. The gearbox also contributes to design efficiency. Its nested carrier configuration affords packaging advantages. Superior on-road performance A front independent suspension with MacPherson struts and a rear independent multi-link suspension absorb on-and off-road obstacles while providing superb comfort for vehicle occupants. The front suspension provides 6.7 inches of travel, while the rear suspension provides up to 7.8 inches of travel for better articulation. The isolated rear cradle, high-strength, low-alloy front crossmember and superior torsional rigidity all contribute to the quieter, smoother ride and superior handling characteristics drivers will experience in the Cherokee. The 2019 Jeep Cherokee is equipped with an electronic power steering system (EPS), which improves fuel efficiency and contributes to the Jeep Cherokee’s nimbleness with a turn circle radius of more than 37 feet in 4x2 models and approximately 38 feet in 4x4 models. With EPS, the power assist is provided via an electric motor system rather than a traditional hydraulic system. Because the system is fully electronic, the driver experiences optimal steering effort at all vehicle speeds, and there is less noise and better fuel efficiency since there is no parasitic loss from a power steering pump. This technology also enables active safety features, such as LaneSense Lane Departure Warning with Lane Keep Assist and ParkSense Parallel/Perpendicular Park Assist. Unmatched Jeep 4x4 capability The 2019 Jeep Cherokee highlights a choice of three innovative 4x4 systems that have been enhanced for unmatched 4x4 capability for all weather conditions. Jeep Cherokee maintains its place as the benchmark mid-size SUV with rear-axle disconnect technology that results in reduced energy loss when 4x4 capability isn’t needed, while improving fuel efficiency. The rear-axle disconnect seamlessly switches between two- and four-wheel drive for full-time torque management and does not require input from the driver. Jeep Active Drive I Available on the Cherokee Latitude, Latitude Plus, Limited and Overland models, Jeep Active Drive I features an all-new design for Cherokee. Jeep engineers set out to reduce weight and enhance efficiency of the next-generation rear drive module (RDM), which is fully automatic and delivers seamless operation in and out of four-wheel drive at any speed. The result of this new state-of-the-art technology is reduced weight of nearly 17 lbs., and a reduction of low-speed system drag torque by 50 percent, which improves fuel savings. The system does not require any driver intervention or feedback, delivers yaw correction during dynamic events, and improves during both understeer and oversteer conditions. Jeep Active Drive II Available on the Cherokee Latitude, Latitude Plus, Limited and Overland models, the recalibrated Jeep Active Drive II includes a two-speed Power Transfer Unit (PTU) with torque management and low range. The 4-Low mode locks the front and rear driveshafts for low-speed power or towing. Low range provides a 2.92:1 gear reduction that allows for enhanced climbing ability, as well outstanding crawl ratios for severe off-road conditions. The 2019 Jeep Cherokee with Jeep Active Drive II gives the off-road adventurer a ride height increase of one inch, a crawl ratio of 51:2:1 when powered by the 2.0-liter direct injection turbocharged inline four-cylinder engine, and a crawl ratio of 48.3:1 when powered by the 3.2-liter Pentastar V-6 engine. Also, the system has a Neutral state that allows for flat-towing with all four wheels on the ground. Jeep Active Drive Lock Jeep Active Drive Lock includes all the features of Jeep Active Drive II and adds a locking rear differential for superior low-speed traction for severe off-road conditions. Jeep Active Drive Lock is standard on all Trailhawk models. All 4x4 systems feature the Jeep brand’s renowned Selec-Terrain traction control system, which allows the driver to choose the on- and off-road setting for optimum performance.

The easy-to-use instrument cluster displays the basic information for drivers at their fingertips, but also allows them to add information they desire. Drivers can select from a multitude of information, which can be displayed in the center of the gauge cluster, including turn-by-turn navigation, speed, real-time fuel economy, safety warnings, available Adaptive Cruise Control-Plus, audio information and Jeep-specific features, such as Selec-Terrain. The available ParkSense Parallel/Perpendicular Park Assist System is displayed in the center of the gauge cluster and operated with buttons on the steering wheel and the shifter. The graphic walks drivers through the steps necessary to utilize the park assist system. A Jeep designer’s passion for the brand shines through in the park assist screen, which features a 1941 Jeep Willys graphic on each side of the open parking space. Safety and security The new Jeep Cherokee was engineered with more than 80 available safety and security features. The Jeep Cherokee starts with a strong foundation constructed with 65 percent high-strength steel. Engineers then added both active and passive safety and security features, including ParkSense Parallel/Perpendicular Park Assist, Adaptive Cruise Control-Plus, Forward Collision Warning-Plus, and LaneSense Lane Departure Warning-Plus; SOS button; Electronic Stability Control (ESC); Electronic Roll Mitigation; Blind-spot Monitoring; Rear Cross Path detection; ParkView rear backup camera with dynamic grid lines and eight standard air bags. The ParkSense Parallel/Perpendicular Park Assist feature remains a highlight in the new 2019 Jeep Cherokee. Using ultrasonic parking sensors on the bumper the system will find and guide the customer into an available parking space when the driver initiates the parking maneuver. The parking guidance system controls the steering angle automatically and the driver controls the gear position, brake, and accelerator. Parallel parking is possible on either side of the car. During perpendicular parking, the vehicle is backed into the space. Additionally, a new side-distance warning feature now adds greater awareness to drivers of side objects while the vehicle is at low speed and in a parallel parking sequence. Adaptive Cruise Control-Plus is significant for its ability to bring the vehicle to a complete stop without driver intervention, in certain conditions. Radar and video sensors identify the locations of vehicles traveling ahead of the 2019 Jeep Cherokee. The sensors also help ensure the vehicles are separated by a gap determined by the driver. If the gap is dramatically breached, the ESC system can aggressively deploy the vehicle’s brakes to affect a full stop, even if the driver never touches the brake pedal. To resume travel, the driver need only press a button on the steering wheel or tap the accelerator pedal. Forward Collision Warning-Plus addresses traffic-gap changes when Adaptive Cruise Control-Plus is inactive. When radar and video sensors detect a fast-closing obstacle ahead, the system pre-fills the brakes to prepare for emergency driver intervention. If collision risk remains, Forward Collision Warning-Plus correspondingly ratchets up the response with: audible and visual warnings a brief brake deployment to alert the driver a 1.5-second brake deployment to quicken the driver’s reaction time deployment of Advanced Brake Assist, if the driver is not braking aggressively enough Lane Departure Warning-Plus uses a camera-based vision sensor to establish the Jeep Cherokee’s position on the road. If an unintentional lane drift occurs, determined by trajectory change and the absence of turn-signal activation, the system will deliver a visual warning and a haptic warning – the subtle introduction of torque from the electric power steering (EPS) system. If the driver unintentionally drifts too far, the system provides a secondary visual warning.

So we know that the Mazda MX-5 Miata will either use a 2.0L Skyactiv-G for markets outside of North America or a 2.5L Skyactiv-G for North America. But a report from Motoring.com.au says there is a more powerful Miata in the cards. "We will have this ND-series model for maybe ten years, which gives us plenty of time to make many variants. And yes, a turbocharged or MPS variant is one of the options we will definitely consider," said Kudo Hidetoshi, Mazda's head of global public relations. Why turbocharging and not using a larger displacement Skyactiv engine? It would allow Mazda to keep some of the weight loss and 50:50 weight distribution. "[Generally speaking] turbocharging is preferable, even to a V6 now. We can use a lighter engine with the same or more power, and achieve [the] emissions and fuel consumption we need," said Hidetoshi. Source: Motoring.com.au View full article

Nissan’s compact Sentra has been on the market for 35 years. For 2017, Nissan is improving the SR trim which adds a 188 horsepower, turbo-charged direct injection engine. The Sentra’s place in the market is that of a value leader. While it is roughly the size of competitors like the Honda Civic and Toyota Corolla, the Sentra is priced against their smaller siblings the Fit and Yaris iA (nee Scion iA). Starting at $21,990, the value equation translates into the SR trim as well. The primary change for the Sentra SR is under the hood. In place of the standard 1.8 liter naturally aspirated 4-cylinder, Nissan has fitted the 1.6 liter direct injected turbo. This engine, originally installed in the Nissan Juke crossover, produces 188 hp at 5,600 rpm and 177 lb-ft of torque from 1,600 rpm – 5,200 rpm. This translates to an increase of 65 horsepower over the standard Sentra and 52 more lb-ft over a broader RPM range. Customers can select either a 6-speed manual or a retuned version of Nissan’s Continuously Variable Transmission with no change in cost. Further enhancements include a retuned suspension and larger brakes. Changes inside the Sentra SR are minimal, however a premium package will be offered that adds leather seats, Bose audio system, blind spot warning, cross traffic warning, and auto-dimming rearview mirror. We recently took the 2017 Nissan Sentra SR Turbo CVT for a spin. Check out page 2 for more. While the Sentra SR is not a dedicated sport model like a Ford Fiesta ST or Subaru WRX, it does have more energy than others in the sedate small sedan segment. In normal driving, the thick torque band allows the Sentra’s CVT to accelerate smartly without needing to wake the engine up. Acceleration under full throttle is impressive by economy car standards as the car pulls hard throughout the RPM band, but the CVT does the Sentra no favors in terms of engine sound. That said, in all cases, the 1.6T is a much more refined sounding engine than the base 1.8 liter unit in non-SR Sentras. On the dash, there is a sport mode button that changes where the CVT holds the engine rpm in standard driving. This keeps the engine more "at ready" than normal, roughly the equivalent of downshifting in a manual transmission car. Don’t leave it in sport mode for too long or you will start to feel it at the gas pump. Next to the sport mode button is an Eco mode button. Don’t press this one; it takes all of the energy out of the car. Throttle and transmission response are so lethargic that I found the car to be unacceptably slow to respond to throttle inputs. Handling is improved over the base Sentra and the SR model can actually be pretty fun to whip around corners. The leather seats up front are easy to get comfortable in, but they lack the side bolstering to really make this a sports sedan. The 2017 Nissan Sentra SR Turbo fills an interesting niche. It has more power, verve, and premium features than most of the competition’s standard models for not much more cash, yet it isn’t the hardcore sports car like the higher priced Subaru WRX or Ford Focus ST. It’s a niche that has largely been abandoned by the industry, so maybe Nissan can fill it. Nissan provided the 2017 Nissan Sentra SR Turbo during a meeting of the Mid-West Automotive Media Association that author attended. View full article

G. David Felt Staff Writer Alternative Energy - www.CheersandGears.com Bosch Selling WaterBoost Injection for Turbo Engines Seems since BMW M4 using a Bosch water injection system that works, Bosch has decided this is what the future is for all turbo engines and has come out with a solution kit to sell to all OEMs of Turbo Engines called WaterBoost. Essentially this is added to the intake side with a water vapor injection to cool the piston, increasing density and driving longer life and more power from the engine. This technology is not new and has been around since WWII when it was used in supercharged planes to assist during hard maneuvers and intense battle fights. The early days of water injection for auto's started with the 1962 Oldsmobile Cutlass Turbo Jetfire, water injection made another appearance in the 1980's in Formula 1 cars. Bosch states 2019 for kit availability to OEMS and aftermarket. As per the Seattle Times story, biggest challenge will be to get the OEMs to redesign their intake system to accept the waterboost injector and customers having to refill the storage bottle with Distilled water. The second issue might not be so hard at least for Diesel owners who are already used to filling up their Urea bottles to clean up their emissions. Yet will the average petro driver want to deal with refilling a water bottle on the engine and how long will the water bottle last, what happens once it is empty, will the engine still run or stop or detune? Interesting times we live in for the auto industry builders. Big question is what is the cost? Will it be worth the 5% greater engine performance, 13% less fuel consumption and 4% less CO2 emitted per the Bosch web site? Info Source Bosch web site Seattle Times web site

The current Ford Fiesta ST uses a 1.6L EcoBoost four-cylinder. But the next-generation Fiesta ST could be using a turbocharged three-cylinder. “We’re seeing more and more of what we can do with the 1.0-litre engine in development and the signs are promising. It’s a great engine – it sounds brilliant and there’s loads of torque when the turbo comes on boost, so we’re looking into things for the next ST,” said Darren Palmer, Ford's head of small cars to Auto Express. Currently, the most powerful version of the 1.0L EcoBoost three-cylinder produces 138 horsepower. But Ford has been experimenting with the engine to see how much power can be extracted. At the moment, the company has been able to get 202 horsepower. “There’s still a huge demand for the ST – we’ve seen that with the current ST200. But we want to offer more, so expect more performance and efficiency,” said Palmer. Source: Auto Express View full article
