MUNICH -- BMW will debut an eye-catching plug-in diesel-electric hybrid sports car concept at the Frankfurt auto show that the carmaker says combines high performance with high fuel economy.
Called Vision EfficientDynamics, the concept with gullwing doors is powered by a three-cylinder turbodiesel engine and two electric motors. BMW says the concept visualizes "the dynamic performance typical of a BMW against the backdrop of future demands in sustained mobility."
The 356hp concept has fuel consumption of 3.76 liters per 100km (62.6 U.S mpg, 75.1 imperial mpg) and CO2 emissions of 99 grams per kilometer.
It can accelerate from 0 to 100km (0-62mph) in 4.8 seconds and has an electronically limited top speed of 250kph (155 mph).
BMW says the concept aims to offer the performance of a car from its in-house M tuning division with the fuel economy of a small premium car.
The concept can run for about 50km (31 miles) in electric mode. Energy is stored in 98 lithium polymer cells, which take 2.5 hours to fully charge.
It has all-wheel drive with an electric motor at both the front and rear axles.
