Mercedes is offering two newly designed engines, a 3.5L V6 and 4.7L V8; engines that whisper green, while still screaming performance.
The V6 puts out 306 horsepower and 272 lb-ft of torque while getting a decent 30.9 mpg.
The 4.7L V8 hammers out a whopping 435 horsepwer and 516 lb-ft of torque while still managing almost 25 mpg; though it will be far from slow, with 442 lb-ft of torque available at 1,600 rpm, and all 516 lb-ft pumping at just 1,800 rpm.
Direct injection, which has become a favorite amongst auto companies, helps boost fuel economy without sarcaficing power. The 4.7L recieves a twin-turbo set up, to help the V8 be a little more green. Also, the V6 goes to a 60-degree V-layout, dumping the old 90-degree setup. Added on both engines is a start-stop function.
These two new engines join Mercedes' new AMG 5.5L twin-turbo V8 that produces 571 horsepower and 664 lb-ft of torque while achieveing a respectable 22 mpg.
