Cummins will display a new powertrain, configurable for either a full battery electric vehicle (BEV) or a range extended electric vehicle (REEV) incorporating a compact engine-generator. liter engine is downsized by about 50% in terms of displacement and can achieve up to 10 mpg, significantly lowering the carbon footprint.

The positive results from this test indicate that we can downsize our battery pack, reducing cost and weight of the vehicle, and still achieve the 40 mile all-electric range needed for optimized typical driving. A liquid-cooled, 41 kWh lithium-ion battery pack operates at 700V and provides the energy storage.

Mercedes has also, reportedly, scrapped its extended-range EV powertrains under development, at least partly because they were too expensive and seen as a technological patch. The plug-in series hybrids would have used dramatically downsized engines—a turbo-2 for the EQS—while halving the EV battery pack.

to eliminate turbo lag—in support of aggressive engine downsizing. The system can operate without a wastegate, using electrical energy storage to prepare for the next acceleration event. This takes advantage of recent developments in electric machine design, power electronics circuitry, and energy storage.

Another strikingly different concept evidenced by the PHEV is that it is essentially a large, portable battery that can store energy gathered during one part of the day, and then use it later to power not only itself but also the vehicle owner’s home. The PHEV provides the advantage in all these criteria.

General Motors Chevy Volt series PHEV, which it calls "extended range electric vehicle" (EREV), part of "E-Flex" multi-fuel platform. The advanced technology vehicle would have an extended driving range on battery power alone and would also have a diesel or gasoline engine that could power the car when the battery was low.
