TSI is Volkswagen's award-winning technology for petrol engines. It results in excellent drivability and instant acceleration in every gear. Plus, overtaking is safer and you can power up hills effortlessly, all with impressively low fuel consumption.
Smaller engines, better for the environment
At the heart of TSI is a smaller engine. It's more efficient, as there is less power loss resulting from friction. TSI engines are also cleaner, you'll also save on car tax. So they have a smaller impact on the environment, are kinder to your pocket - and, best of all, they're fun to drive.
Direct petrol injection with charging
Direct petrol injection is combined with a turbocharger. This enhances the engine's combustion efficiency so the TSI engine power output is much higher than that of conventional, naturally aspirated engines.
Torque when you want it
TSI engines are designed to deliver maximum torque from engine speeds as low as 1500 or 1750 rpm. And that has the twin benefit of not only increasing your driving pleasure, but also, cutting fuel consumption.
Direct Shift Gearbox (DSG)
Two independent gearboxes are connected under load to the engine in turn, depending on the current gear, via two drive shafts.
An output shaft assigned to each gearbox applies the torque to the driven wheels via the differential gear. Clutches and gearboxes are operated hydraulically by the gearbox mechatronics.
The electronic transmission control unit, sensors and hydraulic control unit form one compact unit. The control unit uses information such as engine speed, road speed, accelerator position and driving mode to select the optimum gear and to determine the ideal shift point.
The control unit then implements the shift commands in a sequence of precisely co-ordinated actions. Each change takes less than four-hundredths of a second. DSG can be used manually, via the Tiptronic gearlever or the optional paddle shifts.
Advanced Electronic Differential Lock (XDS)
XDS is an advanced electronic differential lock, linked to a sophisticated Electronic Stabilisation Programme (ESP) system.
We designed it to maximise road holding and improve responses, especially when cornering. In moments of fast cornering XDS gives out exactly the right amount of power, providing pressure on the inside wheel to prevent wheel spinning.
The result is better traction and a reduction of any tendency to under steer. You'll experience a more agile, precise and calm driving performance with better traction out of bends. In other words, you can enjoy sporty driving in your Volkswagen, knowing you have a reassuringly higher level of safety.
