Four-cylinder engines will be offered by Cadillac in several of its upcoming models. These compact engines should allow for a sharp contrast with how much fuel Cadillac’s supercharged LSA V-8 in the CTS-V uses up. The difference with this effort from other attempts to downsize the engine (such as the 8-6-4) is that it would be a lot more functional.
Turbocharged Ecotec four-cylinder engines will be fitted into the upcoming full-size Cadillac XTS and compact ATS sport sedan.
These units are expected to deliver between 220 and 260 hp. If consumers respond well to the four-cylinder engines, Cadillac may add a four-cylinder option to the SRX crossover and next-generation CTS too.
As this industry is becoming more focused in China, it adds another reason to using the Ecotec. Because of its 2.0-liter displacement, GM also gets a tax advantage in the Chinese market. Whether US consumers will go for a four-cylinder engine is difficult to guess.
It’s likely that drivers can’t detect the difference between a high-output turbo four and a more conventional V-6. In addition, Cadillac is focused on competing with European model products. For a long time, Audi has had a turbocharged four in its A4 available in the US.
Audi now has an A6 with the same engine slated to be released soon. By 2012, BMW is expected to offer its own two-liter turbo four to the U.S. Apparently, Mercedes-Benz has the same idea with the C250 sedan and coupe.
