Algodoo

I took my spring engine + transmission and put it in this Ford.
Its pretty powerful and has plenty of torque. Instructions are in the scene.

It can be easily be tuned to have more power, just adjust the brake strength of first gear, and the 6 springs on the engine. If you make the spring strength 200, and 1st gear 180,000 Nm, You will accelerate the 22 tonne truck to 27 m/s (60 mph) in less than 1.5 seconds. And I'm not cheating either my making the engine super heavy. The vehicle is 9 times heavier.
