2007 HPA Motorsports FT600 Volkswagen Touareg

It's always fun to beat the competition when you're the underdog. It's like the bespectacled nerd taking down the loud-mouthed bully, the ant carrying the rubber-tree plant, or the low-fat ice cream that tastes as good as the real thing--well, maybe not. But in the case of HPA Motorsports' latest tuner creation, you can have an entry-level V-6 Porsche Cayenne or Volkswagen Touareg that pounds out 100 more horses than the new 500-horse ($96,000) Cayenne Turbo.

HPA has a long history of tuning small VW engines to run with big-muscle sports cars. Sister publication Motor Trend has tested a few of HPA's twin-turbo Golf R32s, including one that rocketed to 208 mph.
