Volkswagen has replaced its two-litre FSI direct petrol injection engine with a 1.4-litre TSI unit – an FSI engine which is then dual-charged through a combination of an engine driven supercharger and an exhaust gas turbocharger arranged in series.

The automaker said the driving characteristics of the new TSI engine are improved over those of the current FSI unit. The belt-driven supercharger operates at lower engine speeds, with the turbocharger coming in as the engine speed increases. The result of this is claimed to be excellent driveability and performance throughout the range with no turbo lag and high maximum torque.


The new TSI engine produces either 140 (same as the outgoing 2.0FSI) or 170 PS. The 170 PS version has the same peak power as a conventional 2.3-litre petrol unit but with % lower fuel consumption, returning 38.2 mpg on the combined cycle. It also produces impressive torque of 177 lbs ft (240 Nm) from 1,750 through to 4,500 rpm.


“The combination of these technologies enables a small capacity engine with a high compression ratio to cruise at part load on high gearing to combine dramatic performance with exceptional fuel consumption for a petrol engine,” VW said in a statement.


Volkswagen is also adding a new 170PS variant to its two-litre TDI engine line.

A development of the 140PS engine, the new motor uses piezo electric elements to control precisely the fuel injection, thus maximising power output but minimising consumption and emissions. Emissions are further reduced by a maintenance-free particulate filter.


Maximum torque of 258 lbs ft (350 Nm) is available from 1,750 rpm. Top speed is 137 mph and 0-62mph (100km/h) acceleration is in 8.2 seconds with combined fuel consumption of 46.3 mpg.


Along with the new petrol and diesel engines, the Golf GT trim has been altered to look more like the GTI with new grille, GT badges, 17″ alloy wheels, lowered suspension (by 15 mm) and twin exhaust pipes.
