PSA HYbrid4

HYbrid4 is PSA Peugeot-Citroën's in-house developed TTR hybrid[1] powertrain system, shared between the two manufacturers.

The system made its production debut on the Peugeot 3008 HYbrid4 in 2011, emitting 99 g of carbon dioxide per kilometer.

[2] The 3008 HYbrid4 returns combined fuel consumption of 3.8 litres/100 km, beating the smaller Toyota Prius.

The HV battery typically lasts about 150.000-200.000km or 6-10 years before starting to lose capacity noticeably.

The vehicle could be driven with a "bad" battery and does not lose the 4WD function, however the EV range is significantly reduced, resulting in poorer fuel economy.

The SMG 180/120 is also used in the Fiat 500e as main traction motor and in the front axle of the Porsche 918 Spyder.

It is also responsible for supplying power to the rear-wheel drive and charging the high voltage battery.
