Autocar says that BMW engineers plan to modify the front-mounted electric motor in the i8, and to tweak its 1.5-liter turbo-three engine, increasing power by about 10 percent, and also will reprogram its six-speed automatic transmission for better performance. That could reportedly improve upon the BMW i8’s current claimed 0-to-60-mph time of 4.2 seconds.
At the same time, a more energy-dense battery could improve driving range. The battery pack could be as large as 10 kWh, up from the current model’s 5 kWh battery. BMW has already shown it can improve EV driving range with updates to the i3, which recently saw its overall driving range upgraded to 114 miles.
Other upgrades in the works for the BMW i8, according to Autocar, are inductive charging and lightweight carbon-fiber wheels.
BMW chairman Harald Kruger has already affirmed his company’s dedication to plug-in cars and said earlier this year that it will, “see further progress in terms of the vehicles’ range, for both BEVs and PHEVs.” Kruger also confirmed that the long-awaited BMW i8 Roadster will launch in 2018; that timing is likely coincide with the debut of the refreshed i8 coupe.
