well, the heavyest diesel i know of being sold here was a 4.2 in a nissan patrol. But only very few were actually sold, due the very high tax rate, any petrol enigne above 2.0, or diesel above 3.0 is close to unafordable to any common ppl.
for example, the grand vitara 2.7 v6, would cost us a yearly $723 on taxes, a 5.7 litre petrol would cost a huge $2.892 each year, only on taxes.
Take a diesel for example, 4.2 litre diesel engine (the biggest i can find data on)would be at $4 038 YEARLY! Taxes only.
Don't care how you put it, but thats unaffordable to most, and those who can, buy a huge v8 or v12 instead.
a 2.8 diesel is quiet a heavy engine to our standards, as said, we get the GV in either 1.6 petrol or 2.0, no word spoken about a 2.7. The XL7 came out with that engine, but i haven't heard of 1 being sold, so quickly replaced with a 1.9 turbo diesel.
