Yes, pretty trick technology that will help light more of the road. The other news is that the new Mercedes M276 DELA 30 3.0 liter turbo V6 engine will find its way under the hood of the facelifted car. It will provide 328 horsepower and 354 lb-ft of torque although mercedes can increase this if they wish (or offer a power kit) in CLS400 guise. This model will start at $72,500. A CLS450 model is technically possible although it may get too close to the CLS550 for comfort.
The CLS63 AMG 4Matic remains the same with its M157 5.5 liter twin turbo V8 as does the CLS550 model with its M278 4.6 liter twin turbo V8 although the latter gets a 9-speed automatic transmission. The CLS550 4Matic keeps the seven speed transmission that is phased out with the rear wheel drive car.
Overall, a very nice update.
