At first, diesel engines made the Europeans quite skeptical, but since the introduction of the Golf D things have changed with almost half of the cars running on this type of fuel. Now the US have started to adopt diesel-engined cars due to the fact that the increasing price of fuel is funneling customers towards more frugal cars. Furthermore, the fact that General Motors asked for help from its European know-how in order to efficiently develop the Chevrolet Cruze diesel sedan, should not come as a surprise. Thus, with the help of GM's center in Torino, Italy, the US market engine is being co-developed. Meanwhile, the program is being supported by GM engineers in Russelheim, Germany, by developing the accessory drive, acoustic driver, as well as other specialized components. Mike Omotoso, powertrain analyst at LMC Automotive, stated that the market for diesel cars in the U.S. was small then, but it was expected to grow thanks to the Corporate Average Fuel Economy requirements together with expected increases in gas prices. He added that the German automakers hadn't had any diesel car competition in North America and GM could do well with it, especially with those younger buyers who did not have the same old prejudices agains diesel.
