2015 Mercedes-Benz E400 Hybrid

Aside from equipment tweaks, the E400 Hybrid is unchanged.

Available as a sedan only, the rear-drive E400 Hybrid carries the same 302-horsepower 3.5-liter V6 found in the popular E350 model, but in this case it's paired with a 27-horsepower electric motor. With this setup, the E400 Hybrid achieves 26 mpg in combined driving and can hit 60 mph in 6.4 seconds. Other mechanicals are shared with its gas-only counterparts, including a seven-speed automatic transmission and a sport-tuned adaptive suspension. It's worth noting that the lithium-ion battery pack doesn't intrude into the trunk, so you get the same 15.9 cubic-feet of cargo space found in all E-Class sedans.

Standard features include a sunroof, a driver alertness monitor, a collision mitigation system, 14-way power front seats with driver memory, LED exterior lighting, and an eight-speaker sound system with a six-CD changer. The interior is finished in your choice of wood trim and MB-Tex (leatherette) upholstery. Two grades of genuine leather are available.

Buyers seeking a higher level of luxury can specify the Premium package, which adds a navigation system, heated front seats, digital audio storage, a rearview camera, power-folding mirrors, a power rear sunshade and a 14-speaker Harman Kardon surround-sound system with satellite radio.

Adaptive headlamps and automatic high-beam control come with the Lighting package. There's also a Parking Assist package featuring a surround-view camera system, front and rear parking sensors, and automated parallel parking assist. You might also choose the Keyless Go package, which provides keyless ignition and access, including a hands-free power trunk lid.

The Lane Tracking package adds blind spot monitoring and lane departure warning. You can go a step further and get the Driver Assistance package, which tacks on active steering assists, rear cross-traffic alert, collision-mitigation braking and adaptive cruise control.

Available as standalone options are ventilated front seats, a massaging driver seat, a rear entertainment system with dual screens, a panoramic sunroof and a steering wheel with wood trim or heat.
