As diesel is becoming more and more popular in the U.S., Chevrolet announces the specs and details of the 2014 Cruze Clean Turbo Diesel model, which offers the best highway fuel economy of any non-hybrid passenger car in America, and “classic muscle car acceleration,” according to Chevy.

They might be exaggerating a little about that muscle car acceleration part, but this Cruze is one torquey little fella. Powered by a sophisticated turbocharged 2.0L diesel engine – featuring an iron cylinder block and a forged steel crankshaft, but aluminum cylinder head and aluminum intake manifold – it offers 151 horsepower (113 kW) and 264 lb-ft of torque (358 Nm).

The engine’s party piece is an overboost function that gives you 380 Nm of torque for about 10 seconds. Using that you can go from 0 to 60 mph in 8.6 seconds. So you get the decent performance, and because it is a diesel, you also get up 47 mpg, equating to a range of 717 miles on one tank of fuel.

“Overboost provides increased performance when the driver demands it, like when passing on the highway,” said Mike Siegrist, GM 2.0L diesel assistant chief engineer. “When the driver leans on the throttle, the turbocharger increases the air and fuel intake over and above what the engine needs for normal torque demand.”
