Only a week after we brought you spy shots of Peugeot’s high-riding 508 SW, and the French carmaker released the first official photos of the production model that will carry the RXH moniker, ahead of its world premiere at the Frankfurt International Motor Show in September of 2011.

The new nameplate isn’t the only thing that differentiates Peugeot’s new crossover from the rest of the brand’s Outdoor models as the 508 RXH comes with all-wheel drive, courtesy of the Hybrid4 diesel-electric hybrid drivetrain.

It is the same hybrid setup found on the 3008 Hybrid4 featuring a 2.0-liter turbo diesel engine with 163HP turbo that drives the front wheels and a 37HP electric motor driving the rear wheels for a combined maximum output of 200-horses and 450Nm (331.9 lb-ft).

Aside from offering a four-wheel drive mode, the hybrid setup also allows the 508 RXH to run on pure electric mode with zero emissions. Peugeot says the high-riding estate model returns a combined fuel economy of 4.2 lt/100km (55.9mpg US or 67.2 mpg UK) with emissions of 109 g/km of CO2. More details on fuel consumption and performance specs will be released closer to the Frankfurt Show.

Peugeot did not say when or if it will offer more powertrain choices for the RXH.

The 508 RXH is based on the estate version of Peugeot’s mid-size model, which was presented last year and is also available as a four-door sedan.

In a similar fashion to Audi’s A4 Allroad quattro model, the 508 RXH rides on a jacked-up suspension, and also comes with distinct styling features including a new front bumper with vertical LED lights on either side, chrome roof rails, bigger 18-inch wheels and wheelarch extensions and sill mouldings to give it something of an off-road look.

Other standard features include an Open & Go system, electric front seats, head up display, panoramic glass roof, dark-tinted side windows, latest generation audio and satellite navigation unit.

The 508 RXH will go on sale across Europe in spring of 2012.
