2015 BMW i8 PHEV Priced At $135,925

September 12th, 2013 by  

At the 2013 Frankfurt Motor Show, BMW unveiled its first plug-in hybrid, which is the i8 sports coupe. The US price is set at $135,925. Decide whether you think this is justifiable after reading the specifications below, and leave a comment or two!

It is a two-door, two-seat car outfitted with full LED, laser headlights, as well as 20 inch wheels. It accelerates from 0 to 60 mph in 4.5 seconds, and can achieve a top speed which is electronically limited to 155 MPH.

This performance is partially attributable to a drag coefficient of 0.26, and the light 3,285-pound curb weight, which was achieved with its “LifeDrive” architecture, which consists of a carbon-fiber-reinforced plastic (CFRP) body (like what the i3 has) and an aluminium platform (aluminium is lighter than the traditional steel).

It is equipped with a 362 HP powertrain that produces 420 pound-feet of torque. This powertrain consists of an electric motor and gasoline engine. The gasoline engine uses only three cylinders to generate 231 HP and 236 pound-feet of torque, and that 1.5 liter gasoline engine, which is mounted in the rear of the vehicle turns a 6-speed automatic transmission. Wow! That engine packs a punch!

The electric motor, which drives the front wheels, generates 96 kW (131 HP) of power (mechanical, not electricity), and 184 pound-feet of torque. In electric mode, this vehicle can travel 22 miles per charge, provided that velocity does not exceed 75 MPH.

Finally, the vehicle is equipped with a 5 kWh lithium-ion battery bank which the performance of this vehicle benefits from as well, as older hybrids had less powerful, heavier nickel-metal hydride battery banks. This 5 kWh pack achieves 4.4 miles per kWh, which is not bad for a vehicle weighed down by a gasoline engine.
