BMW is now showing an exciting sister vehicle to its upcoming i8 coupe, the i8 Concept Spyder, an open-top version of the two-seater. Both cars employ a plug-in-hybrid powertrain system, in keeping with the i brand's focus on vehicles purpose-designed for electrified powertrains; the third model in the i lineup will be the all-electric i3. The i8 Concept Spyder employs a 96-kW electric motor on the front axle and a turbocharged 164-kW (220-hp) three-cylinder gasoline engine driving the rear wheels—both developed in-house. Combined output is 260 kW (349 hp) and peak torque is 550 N·m (406 lb·ft). Acceleration from 0-100 km/h (62 mph) is in 5 s.
