One weekend. One track. Zero excuses.

The Tire Rack Ultimate Track Car Challenge, our annual no-holds-barred track competition, simply seeks the fastest machines on four wheels. 

The rules are brief: Car and driver must just pass a NASA safety inspection. Period.

Run any tire and any suspension type, add seven turbos plus two superchargers, and re-engineer the chassis to your heart’s content. Concentrate on speed, not excuses.

The Tire Rack Ultimate Track Car Challenge Presented by Grassroots Motorsports returns to Virginia International Raceway in May, happening in the center of NASA’s HyperFest weekend.

Who’s welcome? Everyone, pretty much. New, old, factory-bought and home-built. Wings are cool. So are box flares, giant intercoolers and sequential shifters.

This is also a great chance for shops to show off their work–or settle a grudge with another outfit. Awards go deep into the field, too, meaning lots of hardware to hand out.

Pro cars are invited, too. What's faster: a World Challenge car or a Trans Am titan? Let's find out. 

Just want to watch? No problem. HyperFest puts the spectator first, offering ride-alongs, hands-on activities and more. Spectator tickets are available here. See the cars up close and talk to the people behind them.
