es aiming at ensuring the best driving experience. What most people don't know, however, is that VW engine technologies, such as TSI, TDI and FSI, are ground-breaking systems that also help reduce fuel consumption and emissions, for the sake of a better environment. With the price of crude oil on the global market soaring in recent months, Volkswagen's unique technologies can be seen as a key factor in reducing oil consumption and pollution worldwide.
TSI
Volkswagen TSI engine has a small capacity in comparison to traditional performance engines but it boasts both a "turbo-charger" and mechanically driven "super-charger."
This innovative combination ensures power delivery throughout the speed range with no turbo lag, allowing this unique technology and engine to not only deliver outstanding power, but also lower fuel consumption.
As a result, the 1.4 liter petrol engine, which first fit the Golf GT, and now the Golf GT Sport, puts out an impressive 168 bhp and uses its twin-charger technology to propel you from 0 to 100 kph in 7.9 seconds.
Yet, incredibly, it also does over 38.7mpg, and emits just 169g of CO2 per kilometer. When it comes to cost the TSI offers the benefits of low maintenance and durable technology, promising more driving enjoyment from your car.
The innovative TSI engine technology is now available in the Golf GT Sport along with the Golf Plus, Touran SE, Jetta and upcoming Tiguan. Volkswagen has further plans to make TSI technology available in other models, enabling the improved driving pleasure and economy to be experienced on more models in the range.
TDI
Volkswagen's Turbocharged Direct injection (TDI) diesels have led the way in the diesel revolution. Thanks to the "pump injector" system they employ, the TDI engines are responsive and fun to drive, as well as being incredibly efficient.
The pump injector overcomes the problem of pressure lost through fuel pipes. The injector and pump are integrated into a single devise unit. Each cylinder has its own pump unit mounted in the cylinder head and operated by the camshaft, injecting fuel directly into the combustion chamber at pressures up to 30,000psi. These high pressures produce a far more efficient blending of the fuel/air mix, precise control of fuel quantities and injection timings.
It is this clever technology that enables TDI to offer the benefits it does: good fuel economy, reduced exhaust emissions, and substantially increased performance with more torque than traditional injection systems.
Based on TDI technology, Volkswagen has created the impressive 5.0 V10 engine, one of the most powerful diesel engines ever fitted to a passenger car, and more recently the 170PS 2.0 TDI. Fitted to the new Golf GT Sport TDI, this 170PS engine makes it one of the most powerful diesel cars in its segment.
FSI
Volkswagen has moved boundaries for petrol technology with its FSI unit, which takes the TDI principal of directly injecting fuel into the combustion chamber at a very high pressure. Precise metering of both the quantity of fuel injected and the fuel spray pattern brings the petrol engine closer to the efficiency of today's reborn diesel engines.
The benefits of FSI are increased fuel efficiency, better performance and lower emissions, compared with similar-sized non-FSI engines. And yet FSI units produce more power than their equivalent predecessors.
The new Golf, for instance, has several FSI engine options, including 1.6 FSI with 115PS.
