Volvo ECC

[3] The ECC set a new design language for future Volvo models from the S80 onwards, the most obvious styling feature being the stepped waistline, which was inspired by the similar feature on the 200 Series, whilst retaining some of the angular elements from the 700/900 ranges.

[1][3] In contrast to most production hybrids, which use a gasoline piston engine to provide additional acceleration and to recharge the battery storage, the Volvo ECC used a gas turbine engine to drive the generator for recharging.

Also in Volvo's design, the fuel is evaporated and mixed with air before ignition.

[6] The Volvo ECC was debuted at a time when California was seeking Zero Pollution Vehicles (ZPV).[when?]

With its gas turbine, the Volvo ECC was not a zero-emissions vehicle, and hence did not meet the needs of the time.
