Diesel - why aren't there more?

[T3rminator]

Hey guys. I recently traded in the BOSS 260 ute for a Hilux Dual Cab SR 4x4 with a 3L Turbo Diesel. The Hilux isn't actually mine, its my dads but I get to drive it until I head off overseas next year.

I have only had it for a couple of days and I must say I am very impressed with how the 3L 4cylinder turbo carries the hilux, which I think is around 1850kgs. The torque peaks at 1400RPM and it feels like you can almost take off without using the accelerator, although havent tested this yet. : I must admit the available torque at low revs and throttle response with the cable system is very refreshing from the BOSS.

Anyways, I'm curious as to why there aren't more diesel engine driven cars around. They produce peak torque at almost idling RPMs. Fuel efficiency is much better than unleaded cars. And I'm sure with the right mods and development the mid and top range could be improved to match your unleadeds. So why haven't we seen turbo/supercharged diesel V8s in our falcons or commodores yet?
