The updated BMW i3 details were just released and those specs are impressive. But what about the i8 (the "i" car everyone wants)? It too is due for a mid-life facelift, and Autocar has a pretty good idea as to what sort of updates it'll receive. Due to arrive in late 2017, the facelifted i8 will reportedly feature an upgraded gas-electric powertrain which is currently undergoing testing. Exact details are still a mystery, but sources hinted to Autocar the updated electric motor will produce more than the 129 hp currently coming from the existing i8.

The 1.5-liter turbo gasoline engine will remain (it'll have a few updates but nothing major), but expect an overall power boost of more than 10% over the current i8, so figure around 420 combined hp. The six-speed automatic transmission will also be updated, a factor that will contribute to the facelifted i8's improved performance times. In terms of range, BMW is working on a revised battery pack, similar to what's been done with the latest i3. An inductive charging system is being tested and will probably be offered as an option. Chassis improvements are also in the works and carbon fiber wheels are even rumored to happen. Expect the facelifted i8 to debut alongside the i8 roadster, which will benefit from the coupe's improvements.
