Around 1980, car manufacturers turned to diesel engines to boost fuel economy. This was an unmitigated failure, and American automakers gave up on diesels as a result. But GM might get back in the diesel game with the Chevy Cruze.
GM, however, may be leading the charge in bringing diesel engines back to American cars. Holden, GM’s Australian subsidiary, produces a 2.0 liter diesel engine in the Cruze that has a whooping 235 ft-lbs of torque while delivering similar gas mileage to the base model Cruze (about 34 mpg). That’s almost 90 ft-lbs more than the 1.4 liter turbocharged EcoTec found in the base Cruze, which makes a paltry 148 ft-lbs of torque.
As it is, GM offers a diesel engine option on the Cruze in most other markets, some of them rated as high as 50 mpg. However, GM also offers a 42 mpg highway rated version of the Cruze called the Cruze Eco, so a diesel Cruze would either have to be cheaper, or way more fuel efficient. Still, I think this is a wise move on the part of the General and it could herald the return of clean diesel cars to America. Will diesels meet the lukewarm reaction automakers expect from Americans, or has a new age of diesels dawned?
