This is the new Wheelracer, containing many great new features including better physics, cameras, new missions and race hazards.

Most exiting are the addition of 6 race missions taking place on Mars using actual Martian terrain geometry obtained from NASA via the MOLA orbiter.

Take the most powerful motorcycle engine ever built and place it and the driver inside a 8 meter diameter high tech wheel constructed of a carbon-fiber rubber compound and you get....a Wheel Racer!

So what is a WheelRacer?

Technically the vehicle uses a gyroscope controlled, center of mass shift, to propel and stabilize the vehicle. In addition, it has a shock absorber travel distance of over 2 meters making it almost crash proof on rough terrain.

The driving experience is awesome and the vehicle can reach 100mph and boasts an automatic gear box. The engine sound is simply amazing and will warm the heart of any "petrol-head".

Random game obstacles - concrete blocks and jump forward/back flags. These are placed along the race track and are never in the same location from race to race which means the track can't become predictable, you never know what to expect.
