Audi is showing off its first ever diesel-powered TT in Geneva.
The car has a 168bhp 2.0-litre four-cylinder TDI engine that powers the TT Coupe from zero to 62mph in 7.5 seconds, but it can achieve an average of 53.3mpg and emits 140g/km of carbon dioxide.
The Roadster almost matches the Coupe's stats, with a 0-62mph time of 7.7 seconds, average fuel consumption of 51.3mpg and carbon dioxide emissions of 145g/km.
The Coupe costs from 26,350 and the Roadster starts at 28,350.
Order books open next week, with the first deliveries expected in the summer.
