If you’re looking for a fuel-efficient Mercedes-Benz E-Class sedan, your choices in the U.S. market really come down to two models: the diesel-powered E350 BlueTec or the E400 hybrid
, which relies on both a V-6 gasoline engine and an electric motor to return up to 24 mpg in the city and 31 mpg on the highway (according to Mercedes-Benz).
If price is a consideration in your shopping, you’ll probably want to stick with the E350 BlueTec, as its some $3,600 less than the E400 hybrid, which starts at a price of $56,705. As for fuel economy, the E350 BlueTec gets 3 mpg less than the E400 in the city, but one more mpg on the highway. Call it a wash.
Expect the E400 to produce 302 horsepower and 273 pound-feet of torque from its 3.5-liter V-6, which combines with the 27 horsepower and 184 pound-feet of torque from the electric motor to produce a total output of 329 horsepower and 457 pound-feet. That’s enough to get the Mercedes-Benz
hybrid from 0-60 in 6.7 seconds.
As Car and Driver
points out, the E400 is some $5,000 less expensive than the BMW ActiveHybrid 5
and roughly $2,000 less expensive than Lexus’ GS 450h hybrid
, but it comes in at roughly $1,600 more than the Infiniti M35h hybrid
. In other words, the E400 is competitively priced in the segment.
While that may be enough to make the Mercedes hybrid attractive to some buyers, the E400 falls a few mpg short of most others in the class, something to be factored in if fuel economy is your primary concern. The take-away is this: if you're shopping for a luxury hybrid sedan, there is no shortage of solid choices.
