The Audi 1.8 TFSI

Audi is supplying yet further evidence of its leading position as an engine manufacturer by unveiling an entirely new high-tech four-cylinder engine: the 1.8 TFSI signals the market debut of a new family of engines and combines the evolution of the TFSI concept with an entirely new basic engine. The TFSI concept brings together the advantages of petrol direct injection and turbocharging. This innovative technology paves the way for superior road performance and greater dynamism on less fuel and with reduced emissions. The new engine is putting in its first appearance in the Audi A3. With its output of 118 kW (160 bhp) and high peak torque of 250 Nm, it constitutes a powerful basis for sporty driving pleasure.

Audi's engineers have demonstrated the effectiveness of FSI technology in combination with turbocharging not only on racetracks around the world, but also on more than 400,000 occasions in the guise of the much-acclaimed 2.0 TFSI engine. This concept has been systematically refined for the new 1.8 TFSI. The injection pressure, increased to 150 bar, and the new six-hole injectors guarantee highly homogeneous mixture preparation and very efficient combustion. The optimised turbocharger and a new engine management system bring a further improvement in responsiveness and help the torque to build up even more smoothly. The peak torque of 250 Nm is available across a very wide engine speed range extending from just 1,500 rpm all the way to 4,200 rpm. The entirely new basic engine is designed with an eye to high refinement and low vibrations in particular. The 1.8 TFSI consequently redefines the class standard for output, torque and also acoustic behaviour. Its concept makes it suitable for a very broad performance range.

The new high-tech Audi engine is available initially in the A3, both in combination with the six-speed manual gearbox and with the optional S tronic, the dual-clutch gearbox for lightning-fast gearshifts without any perceptible interruptions to the flow of power. With a top speed of 220 km/h and acceleration from a standstill to 100 km/h in 7.8 seconds for the A3 with S tronic, the 1.8 TFSI turns in a superb performance. In the A3 with manual gearbox, the combined-cycle fuel consumption is a mere 7.3 litres per 100 km.
