We’ve brought you numerous spy photos of the 2012 Mercedes-Benz CLS over the past months, and now, new 2012 CLS engine specifications have emerged. If the rumors are to be believed, the second generation CLS is expected to be available in four engine variants – two petrol engines and two diesel. With the exception of the AMG version, all will feature the stop/start technology to improve fuel consumption.
For the CLS petrol engines, the two models said to be coming are the CLS350 CGI and the CLS550 CGI. The first will feature the new direct-injection 3.5 liter V6 engine with an output of 306 PS (301 bhp / 225 kW) and 368 Nm (272 lb-ft) of torque, while the 550 CGI will feature a new 4.6 liter twin-turbocharged V8 that delivers 435 PS (429 bhp / 320 kW) and 700 Nm (516 lb-ft) of torque. The CLS 550 CGI is expected to be offered with an all-wheel drive option as well. As for the CLS Diesel options, look for a 350 CDI with a 3.0 liter V6 producing 185 kW (252 PS) as well as a 250 CDI with a four-cylinder diesel engine producing 150 kW (204 PS).
And while we’re on the subject of the CLS, there’s significant speculation that the Mercedes-Benz CLS Shooting Brake (which made its premiere at Auto China 2010 as a concept) will enter series production for the 2011 model year, meaning those in the market for a larger estate model could soon have another alternative. We’ll keep you posted as new details of the 2012 Mercedes CLS are revealed; in the meantime, you can check out photos of the 2012 CLS in the gallery below.
