Technology
TDI (Turbo Direct Injection)
Performance or Fuel Economy?
Old logic said you had to choose. New logic says you can enjoy both - in equally generous portions, and with added environmental benefits too. Introducing Volkswagen's TDI technology - proof that truly great ideas can combine seeming opposites! Visit your nearest Volkswagen Dealer and arrange to test drive a Volkswagen TDI today.
Performance
The new Volkswagen TDI performs like a sprinter. Whichever TDI model you choose to test drive, prepare to be faced with an impressive amount of power and speed. And not only are TDI's comparable with any of their petrol counterparts when it comes to performance, but they also lose less power at high altitude than other cars.
Environmentally friendly
Optimum combustion is the key to the TDI's ample torque, high efficiency and unbelievable utilisation of energy in the fuel. The Volkswagen TDI engines actually produce fewer emissions than petrol-driven cars. Technological advances have also led to a smoother, quieter combustion process. TDI's use the earth's natural resources sparingly, which means you can drive with a cleaner conscience, not just a cleaner engine.
Fuel efficiency
The new generation Volkswagen TDI engine operates at a very high efficiency. This translates to 30% better fuel economy which means that stops at fuel pumps will be few and far between. With this kind of advantage, it's plain to see the benefit that TDI has on your wallet.
Why diesel?
Long gone are the days where the only vehicles that used diesel were trucks, and the only advantage was fuel economy. Powerful performance, quieter engines, cleaner emissions and plenty of double takes from passers-by... Volkswagen's new generation TDI models have a whole lot more going for them. And as you would expect from Volkswagen, our innovative TDI engines run on this fuel of the future...
- Diesel has a high energy density which means when burned, it releases about 30% more energy than petrol. So you use less to get the same result.
- Diesel burns more efficiently - resulting in less wastage.
- Diesel produces power at lower RPM, resulting in less friction and more power, while burning less fuel.
- With diesel you get more mileage per litre of fuel.
- Due to its increased density (weight) less fuel is lost due to evaporation.
- Diesel emits less carbon dioxide which makes it more environmentally-friendly.
- Diesel emits less carbon monoxide which is highly toxic to humans and animals.
- Diesel does not ignite as easily and is therefore safer in the event of an accident.
Why TDI?
The benefits of Volkswagen TDI are numerous and obvious... even at a glance:
- Efficiency - in some models, you can get over 1000 km on a single tank of diesel
- Power - the high torque output of TDI engines makes for excellent towing vehicles.
- Convenience - there are less trips to the fuel pumps.
- Environmentally friendly - diesel has lower harmful emissions.
- Choice - there's a Volkswagen TDI available to suit your needs.
- Volkswagen's unique Pumpe Deuse "pump-jet technology" allows for a smoother, quieter combustion process, resulting in reduced heat loss and improved low-end torque.
- TDI engines have a high combustion ratio which means more complete combustion and better fuel economy.
- TDI's have a low "pumping loss" (the power needed to draw air into the engine), which results in less energy loss and more energy to power the vehicle.
- High pressure fuel injection results in atomisation of the fuel which means it ignites more easily and more efficiently.
- TDI's innovative technology has resulted in very little air/fuel mixture which means that less unburned fuel is lost through the tailpipe.
- TDI engines are built with more soundproofing, more swirl chambers, a computer that takes engine speed, temperature, air intake and altitude into consideration before delivering the diesel to the engine - resulting in lower noise, increased performance and better fuel efficiency.
