At the 2011 Frankfurt Motor Show, Peugeot revealed a hybrid-electric crossover estate de luxe variant of the 508.
To distinguish it from other 508 models, the RXH features flared wheel arches, as well as a new color-coded grille with three columns of LED daytime running lights on each side.

The Hybrid4 powertrain combines a 120 kW (163hp) 2.0 litre HDi FAP diesel engine with a 28 kW (37hp) electric motor to lower fuel consumption to 4.2 l/100 km.
The powertrain offers four working modes: AUTO, in which the vehicle strives for the best fuel economy, throttle response is slow and the automated manual transmission shifts early, furthermore the vehicle switches to ZEV mode as often as possible.

SPORT mode offers a combined power output of 150kW (200hp) and 450Nm at speeds up to 120km/h, throttle response is very aggressive and the engine revs up to 4000RPM before upshifts; 4WD mode keeps the HDi engine running constantly and charging the high voltage battery to offer constant AWD with 60:40 split at speeds up to 120km/h; ZEV mode is available if the high voltage battery is at least 1/3 full.

In this mode, the vehicle moves only via the rear electric motor and the performance is limited.
ZEV mode is available at speeds of up to ~60km/h with moderate acceleration, the range on a full charge is about ~2miles (~3km), the A/C compressor is automatically switched off in this mode.
If the driver presses the accelerator beyond a certain point, the HDi engine restarts automatically as to offer better acceleration and the vehicle goes to AUTO mode.
Auto Start Stop is available in all modes except for 4WD when the engine is constantly running so that the reversible alternator can top up the battery and provide constant rear drive.

The engine automatically shuts down whenever possible (cruising downhill at speeds of up to 85km/h when the battery is not fully charged or cruising on a level surface at speeds of up to ~60km/h), when coming to a stop the HDi engine shuts down at speeds below 30km/h.
Restarting can occur at any moment, if the HYbrid4 control unit determines that additional power is needed; or the battery needs to be topped up; or the A/C compressor needs to kick in.

The engine also restarts when the battery is fully charged and the vehicle is going downhill, as to offer additional engine braking, no fuel is used in this mode, but ZERO EMISSION is not displayed, as the HDi engine is rotating.
The battery consist of 42 packs of four d size SANYO batteries (201.6 volts when fully charged).
To offer a longer battery pack life the HCU (hybrid control unit) never charges the batteries over 80% of their capacity, nor discharges them under 20%.


The RXH was released in the beginning of 2012.
The 508 RXH was launched in a single high spec limited edition version, before a full range became available.
It is competing with the Audi A4 Allroad, the Volvo XC70, the Passat Alltrack or even more, the BMW 3 Series XDrive.
