Audi A2 1.6 FSI with Direct Petrol Injection
Audi AG Press Release

A shimmering focal point on Audi's exhibition stand: with its polished aluminium body, an A2 show car takes centre stage on Audi's stand at the 2002 Geneva Motor Show. The explicitly metallic appearance of its outer panelling combines the visual lightness of the A2's design with a clear indication that this product majors in the lightweight material aluminium.

There is more to the Geneva show car, however, than merely external qualities. It also demonstrates the pioneering technology that is about to be launched for the top-of-the-range A2 model version: a 1.6-litre petrol engine with FSI petrol direct injection, developing 81 kW (110 bhp) at 5800 rpm. The peak torque of 155 Newton-metres is available at 4500 rpm. The engine's power is transmitted to the front wheels via a manual 5-speed gearbox.

Thanks to the low weight of the car's aluminium body - 995 kg - the FSI engine propels this nimble athlete from 0 to 100 km/h in 9.8 seconds. The A2 1.6 FSI is capable of a top speed of 202 km/h, thanks in part to aerodynamic properties that are pioneering in the compact class.

The free-revving four-cylinder engine is impressive not simply for its sporting talents. The 1.6-litre FSI engine also demonstrates remarkable potential for fuel economy thanks to its petrol direct injection technology. The A2 1.6 FSI covers 100 kilometres on just 5.9 litres of Super Plus petrol (acc. to 1999/100/EC). Bearing in mind its performance figures and ample interior space, this is an unbeatably low value.

The new version broadens Audi's range of A2 models to four. In addition to the two 1.4 versions with TDI and petrol engine, each of which develops 55 kW (75 bhp), the range includes a 1.2 TDI version, which became the first five-door, three-litre car when it was launched in 2001.

This version combines advanced technology, economy, ample space and driving fun to a quite unprecedented degree.

At the other end of the scale there is now the new 1.6 FSI which, in its own way, represents an equally exceptional synthesis. It is the top-performance version in this model line; with its agile running gear and precision steering, all the signs are that it will establish a new standard of dynamism and driving enjoyment. Yet when it comes to fuel consumption, the 1.6 FSI achieves values that are way below those for competitor models with similar performance and power output. It uses an average of only 5.9 litres of Super Plus per 100 kilometres (1999/100 EC).

Thanks to its larger tank, which now holds 42 litres of fuel, it is thus capable of a range of more than 700 kilometres. Together with its excellent performance figures, this gives the A2 1.6 FSI all the necessary credentials of a long-distance vehicle. Even at high average speeds, it will clock up a considerable distance on a single tank of petrol. And it will outstrip even nominally faster competitors as they pull onto the forecourt of the service station for a refill.

The A2 1.6 FSI is rather reminiscent of the Al2 study which Audi exhibited at the 1997 Frankfurt Motor Show: that vehicle already incorporated essential features of the revolutionary aerodynamics and space concept for which the A2 production models ultimately became renowned; as well as its ASF body, it had pioneering engine technology.

It was powered by a three-cylinder engine, an early prototype of the new generation of petrol direct injection engines. With the A2 1.6 FSI now making its début, yet another technological innovation which was first shown on the much-acclaimed Al2 prototype is thus going into volume production, underlining the role of the A2 model line as the technological avant-garde of the compact class.

FSI - the future of spark-ignition technology

FSI petrol direct injection: Audi unveiled the first production version of its new family of engines at the 2001 Frankfurt Motor Show, in the guise of the 2.0 four?cylinder unit with an output of 110 kW (150 bhp). The 1.6 FSI is now the second engine to use this pioneering form of mixture preparation.

The effectiveness of the new technology was first demonstrated compellingly in a motor racing car in June 2001: the Audi R8 which triumphed at Le Mans was likewise powered by an FSI engine, and owed its victory in that notable race in particular to the unique combination of efficiency and economy that is the result of FSI technology.

FSI engines are all-rounders: they deliver more torque and power, and are therefore palpably more dynamic, than engines with conventional indirect injection. What is more, they reduce fuel consumption by up to 15 percent.

It is no mere coincidence that such a quantum leap should seem reminiscent of the revolution in diesel technology brought about by Audi's TDI engines. They, too, succeeded in combining high power output and an effective reduction in fuel consumption to a previously unattainable extent.

So how does an FSI engine differ from a conventional one? On this engine, fuel is not injected into the intake port, but directly into the combustion chamber. The injector, which is supplied by a high-pressure pump and common rail fuel line, is in the side of the cylinder head, and controls the injection time to within milliseconds, at injection pressures of up to 110 bar.
