A special road-legal Formula Ford race car powered by Ford's diminutive 1.0-litre three-cylinder EcoBoost petrol engine has clocked the 11th fastest lap ever around the Nurburgring Nordschleife.

Its time of 7:22 puts it ahead of big-engined supercars such as the Pagani Zonda, Ferrari Enzo and the Lamborghini Aventador.

The unofficial top speed for the car is expected to be 255.5km/h with a 0-100km/h-sprint time of less than four seconds. Its average speed over the 20.832km Nordschleife circuit was a staggering 169km/h.

Equally jaw dropping is the fuel economy from the engine, which Ford claims to be 2.4L/100km at 56km/h, increasing to 5.0L/100km at 120km/h.

Ford engineers had to make the switch from the Formula Ford’s standard 132kW 1.6-litre EcoBoost powerplant to a specially prepared 151kW version of Ford’s globally offered 1.0-litre EcoBoost engine.

For the car to comply as a fully street-legal machine, several improvements had to be made such as the addition of wheel covers, front and rear lights with indicators, along with wing mirrors and a horn. The vehicle was also fitted with road-legal tyres and a six-speed manual transmission.

Ford offers two versions of the 1.0-litre EcoBoost engine in European versions of the Ford Focus with the 74kW variant delivering a claimed 4.8L/100km while the 92kW version delivers 5.0L/100km.

In Australia, Ford offers the 2.0-litre EcoBoost engine in the Ford Falcon and Ford Mondeo, and will launch the 1.0-litre unit in the new Ford EcoSport baby SUV and Ford Fiesta city car from 2013.
