'Pure sportiness and powerful performance, combined with sensational efficiency: the Audi TT Coupé 2.0 TDI quattro (pictured) and the Audi TT Roadster 2.0 TDI quattro are the first series-production sports cars driven by a diesel engine.
These new models are now available to order, priced at £26,350 OTR for the TT Coupé and £28,350 for the TT Roadster. To order or find out more, please contact your Audi Centre.'
So £1k more than the 2litre 200BHP but you get quattro. I think I'd being going for the petrol one though, if I was wanting one!
