The starting pistol is about to be fired for a highly talented young sprinter: the new top version in the A2 range, the A2 1.6 FSI, accelerates from 0 to 100 km/h in just 9.8 seconds. This lightweight athlete with aluminium body and Audi Space Frame ASF reaches a top speed of 202 km/h.

But it is not just these performance figures that make the A2 1.6 FSI such an impressive new car. It is also the first Audi production model to be powered by a spark-ignition engine of the next generation: the bonnet conceals a 1.6-liter unit with FSI petrol direct injection that develops 81 kW (110 bhp).

The peak torque of 155 Newton-meters is available at 4500 rpm. The engine's power is transmitted to the front wheels via a manual 5-speed gearbox.

The lively four-cylinder engine is impressive not simply for its sporting talents. The 1.6-liter FSI engine also demonstrates remarkable potential for fuel economy thanks to its petrol direct injection technology. The A2 1.6 FSI covers 100 kilometers on just 5.9 litres of Super Plus petrol (overall fuel consumption according to 1999/100/EC). Bearing in mind its performance figures and ample interior space, with room for up to five occupants, this is an unbeatably low value.

Thanks to its larger tank, which now holds 42 litres of fuel, it is thus capable of a range of more than 700 kilometers. Together with its excellent performance data, this figure qualifies the A2 1.6 FSI as a long-distance vehicle: with high average speeds, it can cover considerable distances without stopping to refuel.

Two very difference ancestors: the Al2 and the R8

A straight line descends from the A2 1.6 FSI to the ancestor of the entire model series, the Al2 study which Audi presented at the 1997 Frankfurt Motor Show. This vehicle already incorporated essential features of the revolutionary aerodynamics and space concept for which the A2 production models ultimately became renowned; as well as an all-aluminium body based on the ASF principle, it already had pioneering engine technology.

It was powered by an early prototype of the new generation of petrol direct injection engines – in the form of a three-cylinder unit. The launch of the A2 1.6 FSI will consequently see a further technological innovation that was announced by the much admired Al2 study introduced into volume production: the A2 series is thus proving once again to be the technological avant-garde of the compact class.

By contrast, this new car's relationship to a further family member is not immediately obvious at first glance. But the Le Mans winner from 2001, the Audi R8, is more closely related to the new A2 1.6 FSI than its purpose and visual differences would have us believe. This racing car was also powered by an engine with FSI direct injection.

For the winning team, the use of this new technology meant not only a much higher performance potential, but also a reduction in fuel consumption by around eight percent – the prerequisite for correspondingly longer distances between refuelling stops. But that's not all. The drivers also praised the fact that an FSI racing engine allows them to control the power much more precisely than is generally the case with such power units.
