Revealed today at the Paris Motor Show, an all-new gas sipping plug-in hybrid powertrain has been added to the list of options available in Mercedes’ flagship vehicle.

The Mercedes-Benz S550 plug-in hybrid is powered by a 3.0-liter twin-turbo V6 engine with 329 hp and 354 lb-ft of torque, paired to an electric motor that generates 114 hp and 251 lb-ft of torque. Combined, the total system output is 436 hp and 479 lb-ft of torque.

What’s most important here is efficiency, and the S550 PHEV delivers. The car is rated at 2.8 l/100 km on the European cycle, which is equal to a staggering 84 MPG, although those numbers will surely drop under the stricter U.S. EPA tests. As for all-electric range, the S550 is said to be able to travel 20 miles while burning no gas.

Just because it’s efficient doesn’t mean that this car is slow either, with the 0 – 60 mph sprint pegged at 5.2 seconds and the top speed rated at 130 mph. While running in all-electric mode, the S550 PHEV tops out at 87 mph.
