| “This
engine, ideal for powering affordable cars
of the future, offers great performance”
Rogelio Rivera-Nava, Car and Driver Mexico |

From the moment that Volkswagen’s
TSI Twincharger technology burst onto the automotive scene in
late 2005, it was clear to all that the technology was something
special. The ability to equip a 1.4-litre engine with enough
power to match a regular 2-litre was revolutionary
and has since been followed by
other downsized powerplants from the likes of Renault and Fiat.
Thanks to its TSI technology, Volkswagen has not only won this
Awards category, but also finished runner-up with the lower-powered
version of the unit, which omits the supercharger from the setup.
The
TSI engine boasts direct injection, enabling a very high compression
ratio (10:1) to be achieved. Dan Vardie from Romania’s
Autoshow magazine was one of the many judges taken by the concept:
“A
great achievement for small engines. Volkswagen deserves praise
for delivering the right engine for a time in history that’s
dominated by debate about CO2 and low consumption.”
The Twincharger’s major elements are an exhaust turbocharger
and a mechanically driven supercharger that increases the boost
pressure build-up of the exhaust turbo and
fills the ‘hole’ in the torque at low revs. The
turbo and the supercharger have a pressure rating of around
1.53 bar, and the maximum system boost pressure is set at 2.5
bar
at 1,500rpm. This configuration
helps the TSI to reach performance figures of 168bhp and 240Nm
at 1,750rpm. The fuel consumption figures returned are quoted
as 9.6L/100km (29.4mpg), compared with 10.6L/100km (26.6mpg)
for Volkswagen’s 2-litre FSI, which is
of comparable performance.
Other jurors to recognise the qualities of the TSI Twincharger
are Italy-based freelance journalist Matt Davis, who commented,
“This engine makes all drivers smile,” and Marc
Noordeloos from the USA’s Automobile magazine: “Small
displacement engines are the future and VW is ahead of the game.” |
