NASCAR has confirmed that its Car of Tomorrow will be used in 16 races during 2007, and will be fully implemented by 2009.
The Car of Tomorrow is the new specification NASCAR, designed by the governing body's research and development wing over the last five years. The aim of the car is to increase safety and performance, while being cheaper.
The Car of Tomorrow is bigger than the current design and features several innovations to make the car run easier in traffic, including a front air splitter, a straight rather than curved spoiler and a higher angle of windscreen.
The car will make its debut in Bristol's spring race in 2007 and will predominantly be used at short tracks throughout the season. The only exception to this will be the autumn event at the restrictor-plate track at Talladega and the tour's two Road Courses at Watkins Glen and Sonoma.
The 2008 Car of Tomorrow implementation schedule includes 26 events including both races at Daytona and the race at Indianapolis. All events will be covered by 2009.
Manufacturers, teams and industry suppliers all contributed during the design phase, with teams and drivers offering important feedback during the latest round of on-track testing at Daytona.
"The Car of Tomorrow represents one of the sport's most significant innovations, and we feel everyone involved in NASCAR will experience the benefits," said NASCAR president Mike Helton.
"No subject is more important than safety, and while the Car of Tomorrow was built around safety considerations, the competition and cost improvements will prove vital as well."
