Torque matters.
All of the Diesel guys are debating when the TQ numbers will go over 1000, and which brand will do it first...
Let me show in simple math why the engine race isn't all it's cracked up to be.
Lets say your motor has 500 TQ.
And your 1st gear is 6 to 1.
You will have 3,000 TQ!, leaving the tranny.
If your differential ratio is 3 to 1, you will have 9,000 TQ!, to the rear wheels.
If the diff is 4 to 1, it will be 12,000 torque!!
These are BIG numbers, so big that it makes the manufacturers adding 20-50 #s to the motors, seem like small potatos.... Of course an extra 50 TQ would mean an extra 900-1,200 to the rear wheels.
That is the secret magic of gearing.
