Power gear
Some cars in stunts have the ability to reach a so-called power gear or 6th gear. This usually happens while driving in the last official gear with a high RPM, and doing a jump. Some cars can reach it from any speed, when driving on a loop, and shifting to the last gear.
6th gear allows cars to go a lot faster than the given maximum speed and more importantly not even slow down on grass, when driving in 6th gear. These are: Porsche March INDY, Ferrari GTO, Corvette ZR1 and Acura NSX. There are some important differences betwen Power Gear behaviour of those cars:
- The INDY, Ferrari and Corvette go 245 mph in 6th gear, while the Acura only goes 203 mph.
- The INDY and the Acura can reach power gear from any speed using a loop, shifting up to 5th gear before reaching halfway through it.
- Also, INDY and Acura can reach Power Gear on a jump before getting airborne, or while driving around a left/right corkscrew.
- Unlike the other mentioned cars, the Acura is unable to do slide turns on grass or road while in Power Gear - attempting to do so will get the car out of Power Gear. (see, however, Helicopter trick)
For all four cars, power gear also allows the Fence Sliding trick on water. Finding the 6th gear spots on a competition track is the key to victory. 6th gear was officially confirmed by Stunts lead programmer Kevin Pickell as a programming bug.
