Which used Audi A4 saloon should I buy?
While the 2.0 TDI is the economy champion (especially the ‘Ultra’ low emission model), there's plenty to recommend for the petrol cars. The 1.4 TFSI has excellent on-paper credentials but its lower-powered engine can become a little busy; as the 2.0 TFSI (in 190 guise) offers similar economy with improved performance, it’s a better choice. if you're going for petrol it's our pick. The 3.0 TDI models are also good to drive and reasonably economical, but it’s the 2.0 TDI 150 version in the earlier cars, and the later updated 35 TDI cars, that offer the best blend of economy, performance and running costs.
