Cadillac SLS 2.0T SIDI: Brand's first four-cylinder turbo

Cadillac's China division has taken the wraps off the brand's first four-cylinder turbocharged model.

Marking a first for the luxury division, General Motors' Cadillac brand took the wraps off its new SLS 2.0T SIDI earlier today at the 2010 Guangzhou Auto Show.

Although the SLS isn't exactly a new vehicle for Cadillac, what's under the hood of the SLS 2.0T SIDI is. Powered by GM's 2.0L turbocharged engine, the SLS 2.0T SIDI marks the first use of a turbocharged four-cylinder in a Cadillac product.

Essentially the same engine that was used in the Pontiac Solstice GXP, the SLS 2.0L SIDI generates 260 horsepower and 265 lb-ft or torque. Although no performance specs were given, the SLS 2.0T SIDI is likely on par with the V6-powered STS sedan sold here in the United States.

Given the SLS/STS is nearing the end of its lifecycle, it's doubtful that such a model would ever make it to North America. However, the new engine gives GM a viable entrant into Chin's popular 2.0- to 2.5-liter luxury business car segment.
