I've been seeing a few of the Mazda's around lately - they are going to take some getting used to ! Some people don't like the look of the Mitsubishi Triton, the Mazda BT50 makes it look beautiful.
You forgot the Triton on your list (on purpose I bet) Mitsi dropped the 3.2 in 2010, but it's still in the Pajero. Probably some emission thing - the Triton doesn't have a DPF, the Pajero has. But the 2.5 puts out more grunt than the 3.2 did, has a 3,000kg towing capacity, and is supposed to get 12km/l.
For those who don't ''get'' why we use diesels down here, our work Triton is a 2.4 petrol engine, it puts out 94kw and 194Nm of torque. The 2.5 diesel puts out 131kw and 400Nm of torque - that's a 40% increase in HP, and double the torque....and what feels like twice the fuel economy, our petrol ute really suck in many ways. It's a no brainer, no one wants a petrol ute.
The new V6 Nissan should be out soon.
