Who Killed The Twincharger?Not a valid youtube URL
VW’s 1.4 TSI “Twincharger” engine may well have been the most groundbreaking mass-market of the last 20 years, combining a supercharger and turbocharger to create a lag-free, forced-induction driving experience (a feat only Group B racers had previously attempted with any seriousness). Making either 120 HP or 158 HP in a Golf, the 1.4 TSI is rated on the Euro-cycle (non-EPA) at 6 liters per 100 km, or 39 MPG (please note, cross-cycle mileage comparisons are problematic). In the (smaller, lighter) 177 HP Polo GTI, it gets an even better 5.9l/100km. In short, it can be quite powerful, extremely efficient, and more importantly, it offers the flexibility to be tuned for a number of different applications. As a result, it won the International Engine Of The Year Award for 1.0-1.4 liter displacements four times running, and added “Best New Engine” in 2006, as well as “Green Engine Of The Year” and “International Engine Of The Year” in 2009.
And now, according to Autocar, the industry’s tortured tug-of-war between outstanding technical achievements and
crushing profit-seeking grind will call the Twincharger its latest victim. The British mag reports
The company’s 1.4-litre engine, which mixes turbocharging and supercharging, is said to be too complex and expensive to produce.
Instead, VW engineers now believe that new turbocharging technology can achieve similar results at a much-reduced cost.
