Continuing our pre-show Geneva Salon reports, we have just received word that Audi's booth will host the world premieres of the long-awaited TT RS and the A4 Allroad. Details are still sketchy, but it has been said that the range-topping TT RS will make use of a turbocharged version of Volkswagen's U.S. spec 2.5-litre five-cylinder petrol engine pumping out close to 340HP. Naturally, the TT-RS will be fitted with Audi's quattro all-wheel drive system as well as with the latest version of the firm's S tronic twin-clutch semi-automatic gearbox. The TT RS will be available in both coupe and roadster bodystyles.As for the first-ever A4 Allroad model, it will be based on the latest-generation A4 Avant. To justify its existence in the range, the A4 will feature the same Allroad cues as the larger A6, including a higher road clearance, larger wheels and dark-grey wheelarch extensions and redesigned bumpers. The engine range will of course be sourced from the A4.
