This fall, Mercedes-Benz will introduce a new gasoline-fed V6 engine proving that fuel-burning vehicles are not ready to take a back seat to alternative energy setups just yet. The new 3.5-liter V6 engine benefits from multiple fuel saving technologies including a narrow angle (60 degree) block, third-generation piezo-electric injectors, multi-spark ignition, start/stop technology and more. It all adds up to more power with decreased fuel consumption of 24 percent over previous designs.
The 3.5-liter will make its European debut in the S350 and CL350, replacing the previous V6 engines that are only available in hybrid trim for U.S. models. The company claims a peak horsepower rating of 301 and pegs torque numbers at a healthy 272 pound-feet. Even with this newly found power, the 3.5-liter engine manages a claimed 30.9 miles per gallon (U.S.) and a respectable CO2 output of only 177 grams per kilometer. With this new, highly-efficient mill, perhaps Mercedes will reconsider offering a non-hybrid V6 in the S-Class and CL-Class this time around.
