We're continually refining our Turbocharged Direct Injection (TDI) diesel engines to make them even more efficient while still being great fun to drive. They offer refined power, even at low revs, and exceptional fuel economy, which all helps to lower emissions. We are now converting our full range of TDI engines to common rail engines that are responsive, incredibly efficient, cleaner and quieter. And if you're looking for high performance diesel technology you'll find our V6 and V8 TDI engines very impressive. Our award-winning TSI petrol engines mean you no longer have to choose between performance and economy. Small, light and powerful, they blend the best of our TDI diesel and FSI (Direct Injection) engines. The result is outstanding fuel saving, lower emissions and, best of all, greater performance.
