CAR Magazine, a UK publication, reports that the 2014 BMW i8 will possibly deliver 393 horsepower and 406 lb-ft of torque. The vehicle will use an electric motor that delivers 170 hp and which drives the front wheels. The petrol power comes from a 1.5 liter 3-cylinder engine that outputs 223 hp and 295 lb-ft of torque. The i8 has a four-speed gearbox deal with its much broader performance range. BMW i8 can run in full-electric mode for about 20 miles. At full power, 393 hp and 406 lb-ft of torque, the i8 runs to 62 mph in 4.9 seconds. Top speed is capped at 156 mph. Rumor has it that BMW has no more plans for an M version of the i8.
