Some new details about the new 2013 Cruze diesel has been released.
Kicking Tires has found out from GM Powertrain spokesman Tom Read, the new engine will be a 2.0L and come turbocharged. In Europe, a turbocharged 2.0L VCDi diesel inline-four that makes 161 HP and 266 lb-ft of torque is found under the hood of the Cruze. This engine could make its way to the U.S., albeit with a few changes.
In a press release, GM says the diesel engine is currently undergoing rigorous testing in Michigan, Italy and Germany. The automaker says wants to make sure the engine can operate under a wide range of conditions - including extreme temperatures between minus 40 degrees and 158 degrees.
GM says in the press release the engine will come direct injection and a particulate-capturing filtration system to reduce emissions. GM goes on to say the diesel engine will ill offer outstanding fuel efficiency, torque figures and a quiet ride.
No word yet on the fuel economy numbers for the diesel.

Cruze Diesel Will Build on GM’s Euro Expertise
U.S. engine being co-developed with diesel center of excellence in Torino, Italy
DETROIT – When it comes to developing a diesel-powered Chevrolet Cruze for the U.S. market to be introduced in 2013, General Motors powertrain engineers have been there and done that – half a million times last year alone.
The Cruze diesel will leverage global powertrain expertise that has helped make GM’s fuel-efficient diesel engines popular options around the world.
GM sold more than half a million diesel-powered cars across Europe, Asia, Africa and South America last year, including 33,000 Cruzes. The introduction of a diesel option for Cruze – one of the top-selling gasoline-powered cars in the United States in 2011 – is expected to fuel GM’s diesel car sales success.
Diesel engines have long been known for their fuel efficiency and power. Due to a higher compression rate in the engine cylinders and greater density of energy in diesel fuel itself, diesel-powered engines are able to produce more power per gallon than gasoline-powered engines.
For Cruze, powertrain engineers at GM’s diesel center of excellence in Torino, Italy, are working daily with counterparts in Pontiac, Mich., to develop a world-class engine that delivers outstanding fuel efficiency and torque while providing a smooth, quiet ride. In addition, GM engineers in Russelsheim, Germany, are supporting the program by developing the accessory drive, acoustic cover and other specialized components.
“The market for diesel cars in the U.S. is small at present, but is expected to grow due to Corporate Average Fuel Economy requirements and expected increases in gas prices,” said Mike Omotoso, powertrain analyst at LMC Automotive. “So far, the German automakers haven’t had any diesel car competition in North America. GM could do well with it, particularly with younger buyers who don’t have the old prejudices against diesel.”
Future Cruze diesel engine development will benefit from GM’s recent commitment to invest 20 million Euros ($26.5 million) to add five new dynamic benches at its Torino facility for climatic, noise and vibration and chassis dynamometer testing. These additions will speed development time.
“U.S. customers are going to be pleasantly surprised when they get a chance to drive the Chevrolet Cruze diesel,” said Mike Siegrist, 2.0L diesel assistant chief engineer. “Our global team is providing diesel engineering expertise that will give U.S. Cruze customers great quality, torque and fuel economy in a car that’s both fun to drive and practical at the pump.”
Climatic tests simulate temperatures ranging from -40 degrees Fahrenheit (-40 degrees Celsius) up to (158 F) (70 C) and altitudes as high as 10,000 feet (3000 meters). Noise and vibration tests help minimize engine vibro-acoustic response. Chassis dynamometer tests measure emissions.
“We’re able to put the diesel engines through rigorous testing to ensure they operate optimally under a wide range of conditions and also can be integrated seamlessly into the production vehicle,” said Pierpaolo Antonioli, managing director of the Torino Powertrain and Engineering Center. “We’ve pushed these engines in the labs so that the customer can depend on them in real-world driving situations.”
The latest generation of GM diesels has resolved drawbacks associated with the previous engines. Precisely controlled direct-injection fuel systems create a smooth-running engine. Particulate-capturing filtration systems dramatically reduce tailpipe emissions.
“In terms of outward appearances, the difference between the diesel and gasoline engine is going to be difficult to discern,” Siegrist said. “GM’s advanced technologies provide a seamless transition from a gasoline to a diesel car. You get the benefits of the fuel economy and power while preserving a smooth, quiet ride.”
