TT Coupe 2.0 TFSI 211PS Improved Engine

Audi designers and engineers have risen to the unenviable challenge of enhancing the celebrated TT for the 2011 Model Year, creating a new generation model that combines measured yet distinct styling refinements with efficiency boosting technology, including a newly adopted 2.0-litre TFSI engine, which improves fuel economy by up to 14%.

The upgraded 2.0-litre Turbo FSI petrol engine is the technological highlight in the latest range, employing Audi valvelift technology to effect improvements in power, torque and overall efficiency compared with the 200PS version it replaces.

Delivering 211PS between 4,300rpm and 6,000rpm and a 350Nm torque peak between 1,600rpm and 4,200rpm, it enables the TT 2.0 TFSI with six-speed manual transmission to reach 62mph from rest in 6.1 seconds – 0.5 seconds more rapidly than its predecessor - and raises its top speed from 149mph to 152mph.

Even more impressively, it boosts economy potential from 36.7mpg in the combined cycle test to 42.8mpg, and pares back CO2 output from 183g/km to 154g/km.

The Audi valvelift system adjusts the lift of the exhaust valves in two stages depending on need. This reduces flushing losses in the combustion chamber and also ensures that the optimal flow of the exhaust gas is directed to the turbocharger, which in turn ensures that torque is developed quickly.

The combination of turbocharging and direct fuel injection also reduces the combustion chamber temperatures and the resulting tendency to knock. This allows a high compression ratio of 9.6:1, which improves efficiency.
