HYbrid4 is PSA Peugeot-Citroën's in-house developed TTR hybrid powertrain system, shared between the two manufacturers. It commonly takes the form of a diesel engine powering two wheels coupled with an electric motor powering the other two wheels to provide a 4WD hybrid with a short fully electric range. The system made its production debut on the Peugeot 3008 HYbrid4 in 2012, emitting 99g of carbon dioxide per kilometer. The 3008 HYbrid4 returns combined fuel consumption of 3.8 litres/100 km, beating the smaller Toyota Prius. It also operates in four driver-selected modes: Auto, Sport, ZEV (pure-electric) and 4WD. This technology is not as a widespread in Europe as it is in the United States and Canada.
