The only other kind of powerplant that I want to see in the Stinger is a hybrid. I personally think it was a wasted investment to develop a diesel engine for this car, as sales and interest in diesels even in Europe are at an all time low.
Although its power and torque numbers are respectable-with 197 horsepower and 325 lb-ft, it has slightly more oomph than the BMW 420d Gran Coupe-this engine disappoints on both refinement and efficiency.
