The S2000 207 we are campaigning in this year's IRC, started life as a 3 door 207 road car. We then modify the car to enable it to compete on all the different types of rally stages. Peugeot started the 207 S2000 project back in March 2006 when it showed a concept car the Peugeot 207 R Cup at the Geneva Motorshow.
Many journalists wrote that the car was a tease for the 207 GTi but it was in fact Peugeot's next rally car.
Unlike WRC cars the S2000 cars are much nearer there production based models.
The main differences are:- A normally aspirated engine so less forgiving than a turbo charged WRC car.- A control 4 wheel drive system which must be used by all teams- As the cars are designed to be used by customers, and not by a works team. All the parts are designed to be very durable, easy to adjust and not too expensive.
If you wanted to buy a Peugeot S2000 in Tarmac trim it would cost you 20,500 Euros excluding VAT.
The biggest challenge in creating the car was to adapt the 207 bodyshell to accept the control transmission system.All the parts for the car are specific except for a few parts like bearings, screws which have been taken from the 307 WRC car.
The body shell is a standard 207 road car shell which is modified as allowed by the S2000 regulations. The standard road car shell is already very strong with good torsional rigidity as standard, so we just change the rear wheel arches, the transmission tunnel and the rear shock absorber top mountings. For safety we fit an integrated roll cage.
The road car rear suspension is changed from the standard setup by the addition of McPherson struts and trailing arms. To enable these changes we have to create new attachment points and a new rear subframe.
The standard dampers are made by Peugeot and are a development of the units fitted on the 206 and 307 WRC cars.
The steering system is based on a production power steering pump, with calibration from the 407. A specific steering rack is used supplied by Koyo.The power steering is hydraulic not electric due to the limited space available after fitting the 4 wheel drive system.
We use a 4 wheel drive system supplied by Sadev one of the agreed suppliers by the FIA.
The S2000 is a good concept as it is a good comparison between price and performance. It is about a third of the cost of a WRC car. The car is powered by a 2.0 litre engine which started life in the 206 GTi 180. The engine is provided by Soderno but developed by Peugeot Sport. It is a 16 valve four cylinder unit and produces 280 bhp at 8500 rpm.
The gearbox is a six speed sequential unit and a twin disc clutch is used.
So if you want to convert your road going 207 to a S2000, you will need:
-to increase the front and rear track-fit larger wheel arches-fit the necessary air extraction vents-fit a rear spoiler-fit a tubular roll cage-fit bucket racing seats-fit rally specific instrumentation -fit a hydraulic handbrake-fit a sequential six speed gearbox-fit a 2.0 litre normally aspirated engine-fit a four wheel drive system-Modify the suspension and steering-fit larger brakesEtc....
Next blog I will tell you about the IRC and the other cars in the challenge.
