2014 Chevrolet Cruze Diesel EPA Rated at 46MPG Highway


When General Motors first released the new U.S. market 2014 Chevrolet Cruze Clean Turbo Diesel at the Chicago Auto Show this past February, it said that it estimated the car to return up to 42mpg (5.6 L/100km) on the highway. Now, the General has the official EPA estimates in its hands, with the Cruze Diesel rated at 46mpg (5.1 L/100km) highway.

The Detroit carmaker says this number is "better than any non-hybrid passenger car in America". In comparison, Volkswagen's Jetta TDI, Golf TDI and Passat TDI return 42mpg, 42mpg and 43mpg respectively on the open road. The Cruze diesel's 46mpg is better than some hybrids like the Honda Civic (44mpg), but not as good as the Toyota Prius (48mpg) and VW Jetta Hybrid (48mpg).

"We harnessed generations of diesel expertise to adapt our world-class global engine for the North American market," said Gary Altman, chief engineer, Chevrolet Cruze Diesel. "The Cruze Diesel is the best diesel passenger car out there. Chevrolet is redefining the meaning of great fuel economy with this car."

Priced from $25,695, including an $810 destination charge, the Cruze diesel is powered by a 2.0-liter turbocharged unit delivering 148 horsepower (110 kW) and 258 lb-ft of torque (350 Nm), linked to a six-speed automatic transmission. It completes the 0-60mph (96km/h) sprint in a time of 8.6 seconds.

Pretty good for a 2 Liter turbodiesel. I hope it comes with auto start/stop and I hope it gets a CVT for an automatic eventually so the automatic can get decent city mileage. Hmm, only rated for 27MPG in the city and only 33MPG combined according to some sites (like gmauthority) due to the heavy 3475 pound curb weight + slushbox. Impressive 0-60 of 8.6 seconds with the diesel and the heavy weight.

It seems like too little advantage for the increased price, weight and reduced cargo space.

Increased weight: 3100 pounds for the regular Cruze, 3475 for the diesel.

Reduced cargo space: 4.5 gallon Urea tank for emissions takes up space.

Because of the increased weight and the slushbox automatic, city MPG isn't improved. If you cut down the curb weight to something less than 3,000 pounds and took out the slushbox for a CVT or dual dry clutch and add auto start/stop. It'd be a better rounded vehicle. Maybe reduce the diesel to 1.6 liters if you can get the curb weight down enough.

But see, you can't beat a Prius on the EPA tests and difficult to beat in the real world. Their Atkinson cycle gas engine and Hybrid-Synergy-Drive system is too good. But you can get close on the highway with a tad more power, though the heavier curb weight (~3050 vs ~3475lb) kind of saps that away.

Also keep in mind that a modern diesel isn't much more efficient than a similarly sized modern gas engine, it just has more energy to work with since diesel contains more energy than gas. An Atkinson cycle gas engine can be more efficient than a diesel because of simple emissions equipment and good thermal efficiency
