Mercedes-Benz E-Class Performance

While some reviewers say that the 2014 Mercedes-Benz E-Class isn’t the most agile car in the class, most agree that it offers stable, composed handling and a comfortable ride. Many critics are particularly impressed with the new E250 BlueTEC, which they say delivers plenty of low-end power and great fuel economy for the class.

  • "As ever, the E-class leans toward comfort, and literally so when driven in anger. But with its impervious feel, the Benz is also tremendously assured and reassuring on any road, in any conditions." -- Automobile Magazine 
  • "The E250 BlueTec 4Matic likely won't be cross-shopped with used BMW M5s. It's no sports sedan. It is, however, nicely damped and as about as agile as it needs to be." -- AutoWeek 
  • "The new E250 Bluetec feels every bit like a classic, diesel-powered Mercedes-Benz sedan, solid and steady on its course with cushy suspension and commensurate body roll in corners. Low-end torque is abundant for impeccable drivability. The only vintage element missing, apart from blue smoke, is loud engine clatter at idle." -- MSN Autos 

Acceleration and Power

The base 2014 Mercedes-Benz E250 BlueTEC sedan comes with a turbodiesel, 2.1-liter, four-cylinder engine that produces 195 horsepower. The E350 sedan, Coupe, Cabriolet and wagon come with a 3.5-liter V6 that makes 302 horsepower, while E550 models come with a twin-turbo 4.6-liter V8 that generates 402 horsepower. A seven-speed automatic transmission is standard, as is a start-stop system, which shuts the engine off in stop-and-go traffic to conserve fuel. The E400 Hybrid sedan comes with a 302-horsepower, 3.5-liter, V6 engine, which is paired with a 27-horsepower electric motor. The turbodiesel E250 gets the best fuel economy in the lineup at an EPA-estimated 28/45 mpg city/highway, which is excellent for the class.

The high-performance E63 AMG 4Matic sedan comes with a twin-turbocharged 5.5-liter V8 engine that produces 550 horsepower and 531 pound-feet of torque, while the more powerful E63 AMG S 4Matic sedan offers 577 horsepower and 590 pound-feet of torque. A seven-speed automatic AMG Speedshift MCT transmission and all-wheel drive are standard on both models. Mercedes says that the 2014 E63 AMG can accelerate from 0 to 60 mph in 3.6 seconds with a top speed of 155 mph.

Test drivers agree that the turbodiesel E250 BlueTEC delivers great fuel economy, accelerates quickly enough for highway passing and offers plenty of power at low rpm. The more powerful E350 also wins points, as critics write that it accelerates quickly and delivers ample power. Additionally, the high-performance E63AMG pleases reviewers, who note that it offers incredible acceleration with no loss of traction thanks to its all-wheel drive system.

  • "Mercedes figures a 7.9-second squirt from 0 to 62 mph for the E250 diesel, but the car had no trouble passing dawdlers and its four cylinders were impressively muted." -- Automobile Magazine 
  • "There's hardly a hint of tire squeal -- just acceleration, acceleration and acceleration." -- AutoTrader (E63 AMG 4Matic) 
  • "Slip behind the wheel of the new E250 BlueTEC 4Matic, for instance, and you'll enjoy a torquey, surprisingly quiet powerplant that delivers most of its oomph in the lower registers of the powerband. Similarly understated is the E400 Hybrid, whose internal combustion V6 gains 27 horsepower of extra punch from an electric motor. Speed hungry drivers will find more to love with the E350 model, which is motivated by a higher revving 3.5-liter V6." -- Kelley Blue Book
  • "But what really got our attention was the E250 BlueTEC. It might lose 15 horsepower compared to last year's E350 BlueTEC, but we found that, even driving using our worst behavior, we achieved an impressive 34.1 mpg." -- Left Lane News 

Handling and Braking

Rear-wheel drive is standard on the base E-Class sedan, coupe and convertible, while all-wheel drive is available on coupe and sedan models. The E350 wagon and E63 AMG sedan come standard with Mercedes’ 4Matic all-wheel drive system. Most critics agree that the 2014 E-Class sedan offers a comfortable ride and controlled handling. However, a few reviewers write that competing luxury sedans feel more connected to the road, and that the E-Class’ slow steering doesn’t inspire confidence when cornering. 

  • "Heading back into Portland, the E250 handled a series of switchbacks with appropriate Teutonic authority; it feels solid, not stiff." -- AutoWeek 
  • "The suspension's excellent tuning means that, even in the most relaxed of its three modes, it never feels too soft when pushed or too hard over bumps." -- Car and Driver (E63 AMG 4Matic) 
  • "Even with the promise of our E350's Sport package, its handling reactions were far from athletic. And though it weaved through our slalom at 65.1 mph and pulled 0.87g around the skid pad (also comparable numbers to a 5 Series), the Mercedes never felt confidently tethered to the road. Rapid transitions weren't as easily managed as they are in most competitors, and the lazy steering further compounded matters, leaving us guessing how the car would react." -- Edmunds
  • "Handling has also been improved across the board, with all E-Class models delivering more communicative steering feel and a slightly more intuitive grasp of the road below. Cabriolet variants offer comfortable top-down cruising, while the coupe model feels more athletic in corners and tauter overall." -- Kelley Blue Book
