The all new Volvo S60 is coming our way “in 2011” according to Volvo Car Malaysia (VCM). The statement from VCM also mentions the “possibility of offering the T3 and/or T4 for future Volvo models offered here in Malaysia”. The new 1.6-litre GTDi engine badged as T3 and T4 will make its worldwide debut on the S60 and V60, so these cars could be the “future models” VCM is talking about. It’s likely that the S60 will be locally assembled in Shah Alam.

Before we proceed, note that the “T” designation is no longer reserved for performance range toppers. Volvo has a new naming system in place that “ranks” the engines for each model – T6 is more powerful than T4, which is more powerful than T3, for instance. The same thing applies for the diesel “D” variants.

The GTDi name makes one think of a diesel, but is actually a four-cylinder turbocharged direct injection petrol range, downsized like how the Europeans like it. The 1.6 GTDi T3 has 150 hp and 240 Nm while T4 spec gives it 180 hp and 240 Nm, which rises to 270 Nm on overboost. VVT on both inlet and exhaust valves are employed. These engines can be paired to either a six-speed manual or a six-speed Powershift twin-clutch unit – no prizes for guessing which we’ll get!

For the 1.6-litre GTDi, Volvo positioned each injector centrally above the piston, just beside the spark plug. The injectors have six holes each, somewhat unusual for centrally positioned injectors. This gives particularly uniform and finely atomised fuel distribution and greater control on fuel dosage.

In cold starts, the fuel is sprayed into the middle of the combustion chamber prior to ignition. The high fuel injection pressure of 100 bar means that preparation is perfect and less fuel ends up on the cold combustion chamber walls. This helps cut emissions and reduces the amount of fuel consumed. Another benefit is reduced soot particulates compared with a side-positioned injector. In cold starts, this injection style also contributes to quick heating of the catalytic converter, which in turn speeds up the exhaust cleaning process.
