TSi
All of the petrol engines available on the new SEAT Leon feature TSI technology, which together with the in-line, liquid cooling system, direct injection, DOHC, and transverse in front, provides a dynamic performance.
TDi
The whole range of diesel engines, supplied with the common rail fuel injection system, features a turbocharger with self-aligning blades, delivering a superior performance.
DSG
A direct-shift gearbox (German: Direkt-Schalt-Getriebe), commonly abbreviated to DSG, is an electronically controlled dual-clutch multiple-shaft manual gearbox in a transaxle design, without a conventional clutch pedal and with fully automatic or semi-manual control.
Ecomotive
Ecomotive models feature SEAT’s ultra-efficient engines. Although the engines have very similar power and performance figures to their non-eco siblings, lots of tiny little changes have been made to drastically improve fuel economy – a special turbocharger provides the power when it’s needed. It’ll use much less fuel than other turbos when you don’t though. A Stop/Start system is fitted to most Ecomotive models – this will help you get the most out of every last drop of fuel. Other fuel-saving aids include an energy recuperation system meaning you waste less of the car’s energy when you brake.
