Volkswagen news - VW TSi engines launched - 2006

Pens at the ready and pay attention; there's a new acronym to add to your vocabulary.

As with so many abbreviations, the latest comes from Volkswagen and is TSi.

And just like VW's FSi moniker, there's no direct explanation of what TSi stands for, but if we tell you it could well be 'turbo supercharger injection', you should begin to get the drift.

VW has launched a new range of engines that use a supercharger to boost power at low revs, while a turbocharger comes into play at higher revs.

The 1.4-litre TSi engine comes in two versions, with either 138bhp or 168bhp.

Buyers can order this new engine in the Golf now, which only comes in sporty GT trim, which starts at £15,995.
