To have Peugeot's latest hybrid modular technology it takes a 2.0-litre HDi engine and a 37 bhp electric motor put on a single frame. The diesel engine deals with the front axle while the electric motor operates the rear. Such a setup was fist used in the 3008 HYbrid4. Now the Peugeot 508 RXH and 508 Saloon also join the company's hybrid fleet by succumbing to the HYbrid4 badge.

By adding such frugal technology to otherwise resourceful saloons and all-roaders (such as the RXH and Saloon), Peugeot hope to optimize the driving performance and economy and increase the model's versatility. Lower taxation is expected too.

Both of these AWD cars will carry the same HYbrid4 gear thus delivering identical figures of power – 163 bhp from the 2.0 HDi unit plus 37 bhp from the motor at the back. That's 200 bhp in overall power. Their combined drive cycle economy is a charm, yet the RHX is the thirstier from the two with 68.9 mpg – the Saloon can go for almost 10 more miles on a gallon. Also the Saloon has a sub-hundred figure on CO2 emissions standing at 95 g/km. The RHX manages 107 g/km. The top speed for both is around 130 mph and zero to sixty takes 9.0 seconds (9.5 for the heavier RHX).

In terms of equipment, the Saloon HYbrid4 is pretty similar to the 508 Allure - Keyless entry, an ignition button, cruise control with a speed limiter, automatic parking brake with Hill Assist, automatic dual-zone air conditioning, electric folding door mirrors, Peugeot Connect Navigation (RT6) with Bluetooth, Peugeot Connect SOS and Assistance, automatic headlamps and wipers, 18" alloy wheels and half leather seats are all included. All of that for $49,788.

The Saloon however, is trumped by the $53,343 RXH which has an even vaster array of luxuries. On it, you will find 18" Attila alloy wheels, parking aid, a panoramic glass roof, an additional Colour Head Up display, an USB point and acoustic laminated side windows. It also has a higher stance that gives it an overall crossover look.

Both models are available for ordering while shipping will start in May for the RXH and in July for the Saloon.
