A new plug-in hybrid supercar that’s based on last year’s BMW Vision EfficientDynamics Concept might soon arrive, according to German website and newspaper Auto Zeitung. Dubbed as the M8, this car is equipped with a mid-mounted internal combustion engine that’s partnered with an electric drive. This combination results to an output of over 600hp (447 kW).
This plug-in hybrid would use the petrol 5.0-liter 507-hp (378-kW) engine available on the M5 E60 instead of the diesel engine used on the concept. The engine, which delivers up to 520 Nm, is coupled with an 80-hp (60-kW) electric motor at the front axle, and a 50-hp (37-kW) motor on the rear axle. The front motor can do a short burst, raising its performance up to 115 hp (86 kW).
The car, which is powered by a lithium-ion battery, can run 50km on all-electric range. When the battery is plugged into the wall, it requires 2.5 hours of recharge time.
It’s believed that the M8 would be capable of sprinting from 0 to 100 km/h in under 3.8 seconds, and hit a top speed of more than 300 km/h (186 mph). These specifications lead to a combined fuel economy of 62 to 67 mpg, or 3.5 to 3.8 liters of fuel per 100 km.
The 2+2 car weighs only 1,500 kg because it utilizes an aluminum chassis, carbon-fiber panels, polycarbonate windows and four individual Kevlar seats. Despite the M8’s large size of 4.6 x 1.9 x 1.24-meters, this vehicle would be 120-kg lighter than the Mercedes-Benz SLS.
There are speculations that the car has already been rendered by designers and that it could arrive at the market by the fall of 2013 if the BMW board gives its approval later this year.
The company that’s expected to build this car is the BMW-owned performance division, M GmbH. It’s anticipated to be priced at about €150,000. [source worldcarfans via autozeitung]
