VW Touareg Challenge is a good, free racing game for your iPhone. It is also a HD version available for the iPad. downloads4mac tested the app and tells you whether it is worth the app to load.
VW Touareg Challenge offers a good interface and has no long load times. It involves some levels that must be unlocked only with time trials.
Negative: In the app there is only a stage, which includes levels. An update should provide even more stages.
