BMW Developing a Two Internal Combustion Engine & Electric Hybrid System

Sections: Technology Jan 8th, 2010 3 Comments

BMW has just been granted a patent detailing plans for a drivetrain that combines two internal combustion engines and an electric engine. The hybrid system involves a “split engine” approach where the car is driven by one of the engines and the electric motor at low speeds (or while cruising at low RPM). Once more power is needed, the second engine starts and provides extra acceleration and performance.

While specifics are light within the document, there is a mention of both engines being two cylinder units. With BMW having such an excellent range of two cylinder engines from Motorrad, one could easily see this technology being leveraged in this way.

You can see the entire patent below.

An interesting move, could surely see this development at the heart of Project-i

Wonder if the internal combustion engines will be diesel? A 60 to 70 mpg BMW would be interesting.

About BimmerFile

BimmerFile is dedicated to bringing you the most interesting news, links and reviews related to the BMW brand and it's vehicles.

We believe in the old school BMW ownership experience. We believe in garage nights with a six pack and some friends. We believe in 2002s, in E30 M3s and E34 540s with the 6 speed. We believe in progress in both design and engineering but we haven't lost sight of what made the brand and its products great all those years ago. And yes, we believe in the manual transmission.

We long for the days of the wave and for the days of roll-up windows. Yet we love the gadgets on the inside and the xenons on the outside.

In short, we can't get enough of BMWs. This is BimmerFile.
