Come early February, General Motors plans to unveil the diesel version of the Cruze sedan in its home market, the United States of America. The US-spec Cruze Diesel sedan will join the petrol powered versions and is expected to feature a facelift of sorts considering the fact that GM plans to sell the 2014 model of the Cruze Diesel in Uncle Sam country. The big question remains whether GM USA will borrow cues from the facelift that the Cruze saw in 2013, at the Busan Motor Show. The diesel powered Cruze sedan will be pitted straight at the Volkswagen Jetta TDI model that is also sold in the USA.
The diesel powered Cruze’s high fuel economy and a range of 700 Kms on a single tankful of diesel are expected to be major selling points. The Cruze Diesel sold in the US market is expected to feature the 2 Liter Z-Series turbo diesel engine that is an all new motor, a big step up from the previous 2 Liter turbo diesel engine that used to power the Cruze Diesel. The new engine comes with a higher power and torque output of 165 Bhp-380 Nm, figures that are significantly higher than the Jetta’s 140 Bhp-320 Nm output that the 2 Liter TDI motor manages to churn out.
The engine is mated to a 6 speed manual gearbox as standard while a 6 speed automatic gearbox is offered as an option. The 2 Liter Z-Series turbo diesel engine of the Cruze gets a new maintenance free chain drive for the cams instead of the cam-belt, which required replacement after a certain number of miles clocked. Also, the engine’s bore and stroke numbers make for a square layout, as opposed to the long stroke design of the previous motor. This change has been effected to improve response of the engine.
Also, the compression ratio of the new Z-Series engine, at 16.5:1 is lower than that of the older VCDi engine while the variable geometry turbocharger of the new Z-Series motor features higher boost of 2.2 BAR. The engine now gets start-stop system as standard, another feature aimed at boosting fuel economy. Expect these changes to make it onto the US-spec Cruze diesel as well. Also, other mileage maximizing features like low resistance tyres are expected to make it onto the US-spec Cruze diesel sedan, as the car will be positioned as a ECO model.
