Mercedes S550e Luxury Plug-In Sedan

Mercedes Benz;S-Class Plug_in_HybridThe plug-in hybrid Mercedes-Benz S550e is world-class in every way. It’s also environmentally friendly with its efficient powertrain, which integrates a twin-turbocharged V-6 engine and an electric motor with a seven-speed 7G-TRONIC automatic transmission. The combination provides premium sedan buyers a luxury driving and ownership experience with the benefit of 14 miles of zero-emission electric driving. Overall driving range provided by the S550e’s 141 horsepower electric motor and 329 horsepower 3.0-liter V-6 is a total of 450 miles.

An array of advanced technologies optimize engine performance while reducing emissions, fuel consumption, and noise. These include rapid-multispark ignition that can fire up to four times-per-millisecond, high-pressure direct injection that can fine-tune fuel spray in 0.1 millisecond, a lightweight die-cast alloy block, widely variable valve timing, reduced friction, and on-demand ancillary components that de-activate when unneeded. An E-Boost feature enables the electric motor to raise total torque up to 479 lb-ft for quick 0 to 60 mph acceleration in just 5.2 seconds. The S550e has remarkable efficiency of up to 63 MPGe (miles per gallon equivalent) on the highway while driving on battery power. A drag coefficient of 0.27 CD contributes toward energy savings.

Mercedes Benz;S-Class Plug_in_HybridFour drive modes can be selected: The intelligent Hybrid mode optimizes use of the gasoline and electric motors together based on conditions and terrain, and even uses navigation data about the route. All-electric E-Mode offers emission-free driving around town. E-Save conserves battery power on longer highway trips and allows all-electric driving as desired in urban areas. Charge mode maximizes battery replenishment.

Economy and Sport programs vary the car’s performance character while favoring electric or gasoline power. A third Economy+ program activates accelerator pedal tactile feedback that aids more efficient driving. Whenever it’s possible to save fuel by coasting, a double pulse in the pedal encourages lifting off the accelerator. When using all-electric E-Mode, pushing the pedal beyond a distinct pressure point engages the gas engine for an instant boost of power.

Mercedes Benz;S-Class Plug_in_HybridAdvanced driver assist systems are prevalent in the S550e. These include Distronic Plus with steering assist, BAS Plus with cross-traffic assist, pre-safe brake with pedestrian recognition, blind spot assist, active lane keeping, and speed limit assist. The S550e also features enhanced radar-based regenerative braking. The extremely well-appointed cabin features dual 12.3 inch high resolution screens for driver instrumentation and a center display.

With its sleek styling, refined and accommodating interior, and plethora of advanced on-board electronics, BMW’s $96,600 S550e gives luxury sedan buyers yet another reason to opt for an environmentally-positive plug-in hybrid.
