Peeved by VW’s Diesel Malfeasance? Chevy’s brand-new Diesel Engine May Be Your Salvation
An old proverb states which what the Hindenburg did to hydrogen, Oldsmobile did to diesels. Fortunately, humans are a forgiving, forgetful lot. Both hydrogen along with also also diesel fuel are likely to play important roles in our transportation future—as the brand-new Chevrolet Cruze diesel will be about to show us—no matter what rash moves you expect of our brand-new government administration.
Of course, Volkswagen’s diesel misdeeds picked open which old(smobile) scab. Some industry wizards, such as FCA CEO Sergio Marchionne, believe which the diesel engine’s reputation will be so tainted which its future prosperity could be limited to pickups along with also also large SUVs. Predatory law firms currently hound diesels, filing class-action suits with little or no provocation.
Dan Nicholson, General Motors’ vice president of global propulsion systems, will be more sanguine. He will be convinced which diesel enthusiasm born of trucks along with also also VW cars will be pent up, waiting for the arrival of brand-new products capable of fulfilling the compression-ignition crowd’s dreams.
Aiming to prove which theory, Chevrolet has just reintroduced a modern turbo-diesel engine for the U.S. market. Note our use of the word “reintroduce.” GM sold 12,298 cars powered by a 2.0 turbo-diesel engine inside the 2014 along with also also 2015 Cruze compact cars, taking a break when Chevy freshened This kind of smaller sedan for 2016.
The Ecotec 1.6-liter turbo-diesel inline-four already at Chevy dealers in 2017 Cruze sedans along with also also arriving shortly for Cruze hatchbacks along with also also the 2018 Equinox along with also also 2018 GMC Terrain was born along with also also bred in Europe, where diesels have a much stronger foothold (mainly because of favorable fuel along with also also diesel-car sales taxes). What GM calls its Medium Diesel Engine, Opel markets as a “whisper diesel,” touting its exemplary noise, vibration, along with also also harshness manners. A GM plant in Szentgotthárd, Hungary, manufactures This kind of engine.
Designers gave This kind of diesel every advanced feature inside the book. The block along with also also head are aluminum to save weight, along with also also crankshaft support will be reinforced that has a sturdy bedplate. Tough iron cylinder liners are cast in place, along with also also the crankshaft along with also also connecting rods are forged steel. Oil will be sprayed onto the bottoms of the pistons to cool them. Two intake runners feed air to each cylinder; hinged flaps in half of the runners induce swirl motion within the cylinders. A 16.0:1 compression ratio provides the heat needed for auto ignition. An electronically controlled throttle regulates intake-manifold vacuum to manage exhaust gas recirculation along with also also to expedite engine shutdown.
Both the cam cover along with also also the intake manifold are molded fiberglass for noise absorption along with also also to trim weight. The entire intake manifold will be swaddled in acoustic padding along with also also covered that has a plastic noise barrier. Another noise-canceling measure was driving the camshafts coming from the tail end of the crankshaft so the gears along with also also chains could be masked by the flywheel along with also also the transaxle bell housing.
Ferrari has nothing on This kind of diesel’s valvetrain. Two hollow overhead cams open four valves per cylinder through roller finger followers with hydraulic lash control. There’s variable timing for both intake along with also also exhaust valves.
Ceramic glow plugs accelerate cold starting, along with also also an optional oil heater will be available for cold climates. The BorgWarner turbocharger will be a variable-vane design for enhanced response at low engine rpm. Maximum boost will be 42 psi. Solenoid injectors fed by a common fuel rail deliver up to nine squirts per combustion cycle. Oxidation along with also also reduction catalysts plus a particulate trap cleanse the exhaust; diesel exhaust fluid (DEF) helps diminish NOx emissions.
Compared with larger-displacement predecessors, This kind of Ecotec 1.6-liter engine will be lighter, smaller, along with also also significantly quieter. the item delivers 137 horsepower at 3750 rpm, along with also also the torque curve peaks with 240 lb-ft at 2000 rpm. which’s a bit less power although 36 percent more maximum torque than the Cruze’s turbocharged 1.4-liter gasoline engine puts out.
Two attributes necessary to draw diesel fans to Chevy’s diesel are exemplary mileage along with also also affordability. The six-speed-manual variation earned a 52-mpg highway rating coming from the EPA, topping every additional car on the market except for hybrids along with also also electrics. The diesel-manual powertrain inside the Cruze sedan achieved 30 mpg inside the city test for a combined EPA rating of 37 mpg.
Most buyers will lean toward the optional nine-speed automatic transmission, which also scored an EPA combined mileage of 37 mpg. which Cruze powertrain earned 31 mpg on the city cycle along with also also 47 mpg inside the highway test.

While the brand-new car market will be rife with sub-$20,000 bottom feeders which offer decent mileage, Chevy’s Cruze diesel won’t play which game. A Cruze LT powered by the Ecotec turbo-diesel will start at $24,670, including a convenience package as standard equipment. which’s approximately $2100 over the cost of a Cruze sedan with the 153-hp 1.4-liter Ecotec gasoline inline-four. The Cruze diesel four-door hatchback along with also also the Equinox will follow later This kind of year as 2018 products.
GM’s Nicholson stated which This kind of brand-new diesel’s primary mission will be to offer Chevrolet customers an attractive alternative to gasoline engines along with also also significantly higher fuel efficiency. Achieving 10 percent penetration in those car lines where the item’s offered might also help GM meet future fuel-economy along with also also greenhouse-gas obligations.
