• Audi TT 2.0 TFSI takes first and fourth places in efficiency contest
• Needs just 1.6 liters of fuel per lap on the Northern Loop (20.8 km)
• Undercuts NEDC consumption for city by 28 percent

In the second heat of the ‘RCN Green Challenge’ held on the Northern Loop of the Nürburgring, Audi once again proved that performance and efficiency are not mutually exclusive: Two Audi TT 2.0 TFSI models entered the efficiency contest, finishing in 1st and 4th place. In this four-lap competition in Germany’s Eifel region, the drivers of the victorious TT Coupé boasted an average fuel consumption of only 1.6 liters per each lap of 20.832 kilometers (12.94 miles). With these results, the winner beat the standard city consumption serving as the benchmark by 28 percent – a feat unmatched by any other participant.

During the contest, the Audi TT achieved an average fuel consumption of 7.7 l/100 km (30.55 US mpg) on the track. The RCN Green Challenge was held for the first time this year with the goal of combining speed, fuel efficiency and driving enjoyment. Car racer Hans-Joachim Stuck sponsored the contest. Audi entered two series-production 200 hp (147 kW) Audi TT 2.0 TFSI models approved for normal street traffic and equipped with six-speed manual transmission and front-wheel drive.

The efficiency contest was not simply about chasing the fastest lap times. The goal was to maintain the greatest level of fuel efficiency within a prescribed amount of time. The target time was based on the power-to-weight ratio of each vehicle and ranged from 10 to 15 minutes per lap. The drivers were challenged with meeting their target times as precisely as possible. This factor was evaluated along with their average consumption compared to the NEDC figure for the city cycle.

The 2.0 TFSI is available on the Audi A3, S3, A4, A6 as well as on the Audi Q5 and TT in power classes ranging from 125 kW (170 hp) to 195 kW (265 hp). In the highest power class of 200 kW (272 hp), the engine enables an Audi TTS Coupé equipped with the optional S tronic dual-clutch transmission to accelerate from 0 to 100 kilometers per hour in just 5.2 seconds.”

• Fifth win in a row for the Audi 2.0 TFSI four-cylinder engine
• Already over 1.3 million sold worldwide
• Even greater torque and efficiency thanks to Audi valvelift system

For the fifth time in a row, a jury of 64 leading motoring journalists from over 30 countries has voted the 2.0-liter FSI the ‘International Engine of the Year’ in the 1.8 to 2.0-liter category.

‘A blend of performance and efficiency. An example to all engine manufacturers’, concluded the jury. It was particularly impressed by the way the Audi-developed engine combines pulling power, economy and excellent handling.

The latest version of the two-liter TFSI engine in the Audi A4, A5 and Q5 is equipped with the Audi valvelift system that regulates the valve lift in two stages. It acts on the turbo engine’s exhaust valves. Together with the intake camshaft that can be adjusted through 60 degrees, it improves the charge cycle and boosts pulling power. The driver experiences the Audi valvelift system as a technology designed to enhance driving fun – it guarantees a spontaneous, dynamic torque buildup all the way up from rock-bottom revs. This characteristic means the engine encourages the driver to shift up sooner, promoting lower revving and therefore a more economical driving style.

The 2.0 TFSI is available in performance categories ranging from 125 kW (170 hp) to 195 kW (265 hp) for the A3, S3, A4, A5 and A6 car lines, as well as for the Audi Q5 and TT. In its most powerful manifestation with an output of 200 kW (272 hp), the engine propels an Audi TTS Coupé, equipped with the optional S tronic dual-clutch transmission, from 0 to 100 kilometers (0-62.14 mph) per hour in just 5.2 seconds.

Audi was the first manufacturer in the world to combine gasoline direct injection with turbocharging in volume production. The success story of the 2.0 TFSI started in summer 2004, when it made its debut in the Audi A3 Sportback. Over the subsequent five years it was not only crowned ‘International Engine of the Year’ on five occasions, but also the engine of choice for over 1.3 million customers.
