Power gear

Some cars in stunts have the ability to reach a so-called 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)

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.
