Both solutions enable stop-start functionality and can help reduce the fuel consumption of a traditional internal combustion engine by 2-3% during the standard driving cycle and by up to 15% in congested urban traffic. Allowing the engine to stop before the vehicle does, maximizes the fuel economy benefits of a vehicle coasting to a stop.

Fuel consumption ( ECE ) 1 (L/100km). 1 Given that US EPA fuel economy figures for the vehicles are not yet available, we are using the ECE fuel consumption figures from Europe as a means to provide a comparison across vehicles, and are providing the estimated EPA figure where available. Acceleration 0-60 mph, seconds.
