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 99 g 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.
