The big difference between these engines when it comes to low RPM torque is the turbo charger. There are turbocharged, direct injection gas engines available in production cars that are a match for the latest DM,PS or Cummins when it comes to low RPM torque per liter of displacement and blow them away when it comes to peak HP. Fuel economy and durability may be a different story however.
Although I agree with you to a point, when your talking car engines I'd still take the diesel.
546 lb ft and 381 HP 3.0 liter 45 mpg diesel
" It's interesting to note the rapid fuel consumption dropaway with the extra weight - the similarly sized BMW M550d xDrive Touring returns consumption of 6.4 litres/100 kilometres (44.1 mpg imp) and CO2 emissions of 169 g/km, while the heavier BMW X5 M50d returns 7.5 litres/100 kilometres (37.7 mpg imp) "
Don't forget they are reporting Impg. So in a slightly heavier vehicle, it's not much over 30USmpg in the SUV. And thats if it hits the rating.
