BMW is preparing a more potent version of the i8 for its centenary celebrations in 2016, sources have revealed.
The new model, rumoured to be called i9, would use the same carbonfibre tub as the i8 but would get more aggressive styling, a larger engine and a more powerful electric motor.
The engine is understood to be the new modular 3.0-litre six-cylinder unit that is in development and set to appear first in the upcoming 7-series replacement.
The i9 will be the next model to join BMW’s i sub-brand. Also planned is the i5, a stretched version of the BMW i3.
Currently in use in the i8 is a three-cylinder 1.5-litre turbocharged petrol engine in combination with an electric motor. Total power output is rated at 357bhp, alongside 420lb ft.
Expect the i9 to improve on the standard car's 0-62mph sprint time of 4.4 seconds, as well as its 155mph top speed.
