At the corners, though, the dangers come into play in reduced maneuverability and greater likelihood of losing control. While such application may be useful for racing, for most road vehicles this would produce minimal improvement in overall drag reduction. This equation is simply a rearrangement of the drag equation where we solve for the drag coefficient in terms of the other variables. drag area The trailing car suffers a reduction of downforce on its front tires, resulting in a loss of stability and handling coming out of turns. Side mirrors both increase the frontal area of the vehicle and increase the coefficient of drag since they protrude from the side of the vehicle. "ESPN Will Show the Unseen of NASCAR." The Physics of NASCAR: How to Make Steel + Gas + Rubber = Speed. A boattail can greatly reduce a vehicle's total drag. Wing appendages, used on Formula One and Indy cars, are turned upside-down to provide downforce instead of lift. Replica of Buddy Baker's 1969 Dodge Charger Daytona - Source: Wikipedia Because lift and downforce are opposing forces, part of the effort to build a stock car with a strong downforce involves overcoming lift. PJ1 Trackbite is a sticky, water-resistant substance that increases grip. The air that glides smoothly over the roof grows turbulent above the rear window and behind the car, exerting a backward force on the vehicle. NASCARs last generation vehicle, the Generation 6, or Gen 6, as its known, was introduced in 2013. Nonetheless, for practical and style reasons, a kammback is more commonly seen in racing, high efficiency vehicles, and trucking.[24]. After eight years of racing, though, it was time to update the look of NASCARs top series to more closely resemble their roadgoing counterparts, which too had evolved over that stretch. Are you surprised at how slippery some cars are compared to others? This leads to various interpretations of what is acceptable, and often lengthy lists of revisions from NASCAR in terms of qualitative styling, as compared to the production vehicle. According to. Both cars can travel faster than either car can go by itself [source: Turner].
