2014 Chevrolet Cruze Diesel: More Details From Chicago Show

Three years after the Chevrolet Cruze compact sedan was launched as a 2011 model, it gains a new model with a diesel engine for 2014--although there appears to be some confusion over just what that variant is called.

The turbodiesel sedan was launched at the Chicago Auto Show last Thursday. Absent one badge on the trunk and few trim details, it looks just like any other Cruze four-door compact sedan.

The confusion over the name stems from differences among various GM sources.

The press release provided to journalist calls the car the "Chevrolet Cruze Clean Turbo Diesel," though presentation slides at the launch event and the trunk badge showed it as "Chevrolet Cruze 2.0 TD."

In questioning after the press event, marketing director Christi Landy told reporters the new model would actually be called the "Chevrolet Cruze 2.0 Turbodiesel."

Whatever the name, discussions with Chevrolet executives after the unveiling brought a few more details of the diesel Cruze to light:

The trim level of the Cruze diesel is roughly equivalent to the mid-level 2LT package

It also uses several of the aerodynamic modifications developed for the Cruze Eco, including active grille shutters and smooth undertray panels

The 4.5-gallon tank for Diesel Emission Fluid (DEF, or urea liquid) is located at the bottom of the trunk

Cruze diesel buyers receive two years' worth of free maintenance, including refills of the urea liquid every 10,000 miles when the engine oil is changed

The car will start to ramp down its performance when it calculates there is only enough DEF for 400 miles, just as GM's commercial DuraMax diesel trucks do

Chevrolet clearly sees the diesel Cruze competing for the same set of buyers as the Volkswagen Jetta TDI

But it also feels that current owners of GM trucks with DuraMax engines may want a diesel Cruze as well--an audience VW has little direct access to

GM has tested the diesel Cruze down to -40 degrees C (-40 degrees F), but proper operation at that temperature requires an accessory block heater

While the diesel version of the Chevrolet Cruze will be built in Lordstown, Ohio, its engine is imported from a plant in Kaiserslautern, Germay

The last diesel passenger car produced by Chevrolet was the 1986 Chevette subcompact

Based on the diesel Cruze sold for several years in Europe, the 2014 Cruze is fitted with a direct-injected and turbocharged 2.0-liter diesel engine producting 148 horsepower and 248 lb-ft of torque.

The only transmission option at launch will be a six-speed automatic, though Chevy officials said they would "assess demand" to see if a manual gearbox was something requested by a significant number of buyers.

Chevrolet estimated highway fuel economy at 42 mpg, but refused to discuss potential city ratings, saying the car was still in the certification process.
