When I drive the Commodore, esp the 3.0L SIDI version V6 it lacks torque and hunts around for gears quite easily. The engine lacks torque as it is 290nm @ 2900rpm.
Would it not be better to fit a Turbo to the SIDI engine, like the LAU six version?
The LAU engine (or LP9) in its lowest power level (186kw) is similar to the LF1 3.0L SIDI six but has 350nm in a wide band 1900-4500rpm.
Off course the current version uses SIDI where as the turbo engine does not.
So, Holden if you want to keep your V6 engine plant in Australia, how about creating a turbo low boost SIDI engine that could keep lower rpm, noise and use less fuel (ULP)? You could have a Hi Pressure version (PULP) to replace the 3.6. Therefore, one engine size in two configurations. Dropping the engine size to 2.5-2.6 L would also help the fuel economy and Holden would not need to spend money to upgrade the Plant.
