Potent 207 at Geneva Show
Peugeot is giving its 207 supermini a fillip with a 280bhp concept model, the 207 RCup, unveiled at the Geneva motor show in Switzerland.
The striking RCup is powered by a naturally-aspirated 2.0-litre 16v petrol engine, that produces 202kW at 8500rpm. Designed by the Peugeot Style Centre, the car is equipped with a six-speed sequential gearbox. Peugeot says tantalisingly that the car “could be the design blueprint for a future Peugeot Sport competition programme” – a reference to the car’s potential for the Rally Super
2000 class. It certainly has the credentials for a race or tarmac rally car. As well as the potent motor, it had road-scraping ground clearance of 100mm, 18-inch wheels with multiple magnesium spokes and fitted 235/40R18 tyres. It also has dual rear exhaust pipes, a deep front air dam containing air extraction ducts ahead of the front wheels and a rear roof spoiler designed to increase downforce.
Beneath the sleek bodywork, the car has been designed to meet the requirements of the Rally Super 2000 category. It has a single compartment chassis and a tubular rollcage, competition bucket seats and four-point safety harnesses. Peugeot is also showing the 307 CC Hybride HDi at Geneva. Peugeot says the car shows its commitment to the protection of the environment through reduced fuel consumption and CO2 emissions. Associating HDi FAP Diesel engine technology with that of a hybrid powertrain, the technological demonstrator is effectively a new step on the path to ultra-low fuel consumption, Peugeot says.
The hybrid diesel engine sets a new benchmark for fuel economy, combining the exceptional efficiency of a smaller capacity HDi engine, operating in its optimal operating range, with that of an electric motor designed mainly for use in town. Its mixed-cycle fuel consumption of 4.1 litres/100km means a gain of 30 percent over a standard 2.0 litre HDi. Peugeot says replacing a petrol engine with an equivalent diesel engine allows a 25 percent reduction in fuel consumption and a cut of roughly the same percentage of greenhouse gas emissions. It says petrol hybrid technology can’t bridge the significant gap opened up by the HDi diesel engine.
However, the combination of a hybrid powertrain and an HDi engine signals a real breakthrough in terms of fuel consumption and greenhouse gas emissions. The gain, compared to a similar vehicle equipped with a hybrid petrol powertrain, is around 25 percent.
Peugeot’s preferred choice was a parallel hybrid powertrain, in which the thermal engine is used mainly to move the vehicle.
It is combined with a transmission that functions in the traditional way, and an electric motor powered by energy stored in batteries. Kinetic energy recovered during the vehicle’s deceleration and braking phases allows the batteries to be recharged. Phases of driving in electric mode are suitable mainly in cases where the thermal engine is least efficient, i.e. essentially low-load situations.
