The 508 RXH is the off-road version of the middle-class estate 508, which comes as a limited edition of 300 cars. With the same technology equipped is the 3008 hybrid. The HX1 Diesel-hybrid Concept thrills with a sensational cw-value of 0.28.

508 RXH
If you love diesel-electric hybrids, let’s hope you don’t reside in the U.S. Yes because Peugeot just unveiled at the 64th Frankfurt motor show its second diesel-electric hybrid – the 508 RXH.

With a combined output of 200bhp from its 2.0 HDi FAP diesel engine and electric motor on the rear axle, the 508 RXH powertrain provides four HYbrid4 modes (Automatic, Zero Emissions Vehicle [electric-only], Sport or 4WD) and 70.6mpg in the EU Combined Drive Cycle, and CO2 of 109g/km. It will be limited to only 300-unit.

On the road, the Peugeot 508 RXH has a dominant road presence and is distinguished by a singular visual identity featuring thee vertical ‘lion claw’ LED daytime running lights either side of a ‘floating’ grille, supported by 18″ wheels, panoramic glass roof and dark-tinted acoustic laminated side windows.

HX1 Dieselhybrid Concept
The HX1 concept delivers an estimated 73.5 mpg (U.S.) while offering seating for six adults. It’s plug-in hybrid drivetrain is mated to a 204 horsepower turbo-diesel engine to power the front wheels, while two electric motors drive the rear wheels. The system — sometimes known as a through-the-road hybrid — has a combined output of 299 hp, and can function as an all-wheel-drive vehicle, or a rear-wheel-drive EV.

Aside from the fancy hybrid tech, a low drag coefficient of just 0.28 also contributes to the slippery look and feel of the HX1.

Its lithium-ion batteries would provide just less than 19 miles of purely electric driving range and would charge at a conventional 240-volt outlet.

Peugeot hasn’t announced any plans to turn the concept into a production car, suggesting instead that some of the HX1’s features will trickle down to other models.
