Peugeot’s RCZ hybrid will deliver 76.35mpg when it goes on sale. The car is currently under review and Peugeot says it is determined to bring it to production if demand is high enough.
The hybrid coupe is a likelihood because the tech has already been perfected in the 3008 Hybrid4, with which it shares a platform. The 3008 hybrid is due to be seen at next month’s Frankfurt show in production form and go on sale in the UK in early 2011.
The 3008 emits 99g/km of CO2 but the RCZ Hybrid4, on show at Frankfurt as a concept, brings this figure down to 95g/km because it’s lighter and has better aerodynamics.
Under the skin, the Hybrid4 is an otherwise conventional front-drive car, powered by a 163bhp 2.0-litre turbodiesel engine that’s fitted with a stop-start system.
However, the car’s rear axle has been modified to incorporate an electric motor that is good for 37bhp and 147lb ft at full tilt. Because of the hybrid powertrain the RCZ now has a multi-link rear suspension.
The Hybrid4 can run in front drive, four-wheel drive and purely rear drive modes; the latter offers zero-emissions travel, though the range is only a few miles, even at relatively modest city speeds.
If the 3008 Hybrid4 proves a sales success, its two-door cousin could arrive soon after, possibly followed by hybrid versions of the 308 and 308CC.
The hybrid powertrain can also easily be converted to use a petrol motor instead of diesel, says Peugeot.
