The third model from the BMW i brand will reportedly be launched in 2018.

The latest issue of the AutoBild magazine features a report that says the i5 will be powered by a plug-in hybrid powerplant, similar to the one in the 5-Series GT hybrid concept. The system will consists of a gasoline engine with 218 HP (160 kW), supported by two electric motors with 150 HP (110 kW) and 272 HP (200 kW). The total output will stand at 640 HP (471 kW).

The report also says the vehicle will be based on the long-version of the 5-Series, built for the Chinese market. In terms of design, the i5 will share some of its design cues with the upcoming 7-Series and will be roughly the same size as the current 6-Series GranCoupe.
