The Mercedes-Benz C220 runs on diesel fuel. Carrying 168 horsepower, a Mercedes 2.1 liter four-cylinder BlueTEC diesel engine powers this C-Class sedan. BlueTEC is a marketing name given to Mercedes' product line of advanced diesel engines, which provide high fuel economy, low emissions and responsive performance.
New in 2014, the Mercedes C220 brought the BlueTEC diesel technology to its C-Class sedan series. Standard diesel engines provide high fuel efficiency, but they also release high emissions due to the high compression ratios and high combustion temperatures. The low emissions rating of the BlueTEC series is due to a selective catalytic reduction system that utilizes a diesel particulate filter and nitrogen oxide trap.
