Nice driving report here of the Mercedes-Benz C-Class. Enjoy!
All engines run through the company’s seven-speed 7G-Tronic transmission. The combination of direct injection, an extra cog in the gearbox and a small overall weight savings help boost fuel economy by up to 15 percent. The gains are bigger in other markets, where an engine stop/start system is also standard. That feature will be coming to the U.S. when fuel economy pressures justify the additional complexity and cost of the system. Mercedes hasn’t released final EPA figures, but offered preliminary combined numbers (by engine) of 24 mpg, 20 mpg, and 21 mpg, respectively.
Like overall efficiency, dynamic performance is also improved. Daimler says to expect a 5.9-second 0-60 mph dash for the 3.5-liter and 7.1 seconds for the other two powertrains.
