Mercedes-Benz E-Class BlueTEC

Motor Trend logo Motor Trend 12/5/2016 Motor Trend Staff

Mercedes-Benz offers the E250 BlueTEC for consumers who want improved fuel efficiency over gasoline-powered E-Class models. The E250 Bluetec has a direct German competitor in the form of the BMW 535d.

History

The first diesel engine available in the E-Class for the U.S. market came in 2005 with the Mercedes-Benz E320 Cdi. This sedan was powered by a 3.2-liter turbodiesel I-6 with 201 hp and 370 lb-ft of torque, achieving an EPA-rated 27 mpg combined city/highway, better than the gas-powered E320's 20 mpg combined city/highway. In 2007, Mercedes-Benz changed its diesel engine designation from Cdi to BlueTEC, and the model received a new 221-hp, 400-lb-ft 3.0-liter V-6 that managed to achieve 26 mpg combined city/highway.

The Latest Generation

Mercedes-Benz axed its 3.0-liter turbodiesel for the 2014 model year in favor of a new 201-hp, 369-lb-ft 2.1-liter turbodiesel I-4 that came equipped in the E250 BlueTEC. This new diesel has an EPA-estimated 28/40 mpg city/highway (rear-wheel drive), a significant improvement over the E350's 20/29 mpg city/highway. Making up for the fact it has about 100 fewer hp, the E250 BlueTEC has a starting price slightly lower than the E350's, making it the most affordable E-Class in the lineup. "Bottom line: Even if your E250 BlueTEC never hits 45 mpg, you'll be plenty pleased to get 700-800 miles of range in such a big, comfortable car that at least matches workaday family sedan acceleration," we said in a First Test review of the Mercedes-Benz E250 BlueTEC.

Mercedes-Benz released a new generation of the E-Class for the 2017 model year, and as of this writing, diesel engine information has not been released.

Why You'd Consider One

Because you are the type of consumer who prioritizes fuel savings and an almost silent engine over acceleration numbers.

Why You'd Look Elsewhere

Because a vehicle's performance is more important than top-notch fuel economy,or you are curious about the new plug-in hybrid E350e and its impressive fuel economy and performance figures.
