But you miss the point...
The increased torque will only matter if the gearing isn't proprionately longer...
For cars of equal mass, torque spread and drag, a car with 150 lb/ft of torque but gearing of 15mph/1000rpm will accelerate at the same rate as a car with 300 lb/ft and gearing of 30 mph/1000rpm regardless of terrain...
Absolute torque is irrelevant, you need to take into account the gearing...
