Pioneered by SEAT's Brand Group partner, Audi, TDI stands for Turbocharged Diesel Injection engine. This type of high performance motor is characterised by economy, reduced emissions and increased, low-end power (torque). The power of the TDI engines takes the Leon to new levels of maximum-strength driving. The motor is available with or without DPF on the New Leon’s 1.9 TDI* 105 hp, 2.0 TDI* 140 hp, 2.0 TDI* 140 hp DSG. The FR promises even more with 2.0 TDI* 170 hp DPF. The general principle behind the TDI is: a turbocharger delivers air to the engine and ensures the cylinder is filled to an optimum level. Then, in the last part of the compression stroke, very high-pressure diesel fuel is injected into the combustion chamber to create a highly combustible air/diesel mix. This reduces emissions, increases performance and, thanks to the engine encapsulation and hydraulic mounts, keeps noise down, ensures smooth running and low vibration. *Complete with selective pump injector technology
