Peugeot 508 RXH• Hybrid  508 saloon and high-riding estate versions confirmed
• Low tax and running costs
• Impressive fuel consumption and range

The Peugeot 508 HYbrid4 saloon and 508 RXH SW estate will both benefit from diesel and electric hybrid technology when they go on sale.

With two distinct flavours, the 508 HYbrid4 saloon offers the features of the standard car, but with lower running costs, while the 508 RXH is a more unique proposition.

Featuring raised suspension and a premium specification, it is the top-of-the-range 508 and is available in SW estate body style only. It will compete with the Volkswagen Passat Alltrack and Audi A4 allroad as well as the Subaru Legacy.

It’s fitted with 18-inch alloy wheels, parking sensors, parking assist, panoramic glass sunroof, colour Head Up Display (HUD), USB connection, noise-reducing side windows and tinted glass.

Both of the new models feature a combined power output of 200bhp, with a maximum of 163bhp going to the front wheels from a 2-litre diesel motor, and 37bhp being supplied to the rear axle by an electric motor. We’ve tested the same system in the Peugeot 3008 HYbrid4.

Peugeot RXHWhile the 508 HYbrid4 manages 78.5mpg, 95g/km of CO2 emissions and 10 per cent Benefit-in-Kind taxation (BIK), the 508 RXH can achieve 68.9mpg, 107g/km and 12 per cent BIK.

Performance is good too, with acceleration from rest to 62mph in 9 or 9.5 seconds for the saloon and estate respectively and a top speed of around 130mph.

The most economical Passat Alltrack has a 138bhp 2.0-litre diesel, returns 49.6mpg and hits 62mph in 10.9 seconds.

But, you’ll pay for all the technology upfront as the HYbrid4 saloon will cost from £31,450 and the 508 RXH from £33,695.

That makes it significantly more expensive than the Volkswagen, and places it in the ring with the A4 allroad, which starts from £31,375.
