Motorsport
Time attack (alternatively known as Super Lap or Tuner Battles) originated in Japan when the tuning media organized the event on race circuits such as Tsukuba Circuit, where it commonly occurs, as a proving ground for street tuned cars built with a large budget by tuning companies. As a result of the quick rise in popularity, tuners developed purpose built cars for the competition, including HKS CT230R Lancer Evolution, with its body made entirely out of carbon fiber. The Lancer Evo is the OEM chassis time attack record holder at Tsukuba.
Unlike other timed motorsport disciplines such as sprinting and hillclimbing, the car is required to start off under full rolling start conditions following a warm up lap where they will have to accelerate out as fast as possible to determine how fast they enter their timed lap. Commonly, as cars consist of modified roadgoing cars, cars are required to wear tires authorized for road use and in all, drivers are allocated to three laps in a final event run; warm-up, timed and cool-down.
Largely as a result of the popularity of the tuning industry, the name appears as a category for modified production vehicles at the annual Pikes Peak International Hill Climb utilizing time attack regulations allowing aftermarket modifications to the car.
Time attack and time trial events differ by competition format and rules. Time attack has a limited number of laps, time trial has open sessions. Rules for time trials are more restrictive.
National Auto Sport Association Time Trial (NASA TT) series is a national auto competition program, utilizing regional series based on a time trial style format, with rules that establish car classifications to provide a contest of driver skill. NASA TT is designed to bridge the gap between NASA HPDE (High Performance Driving Events), and wheel-to-wheel racing.
NASA TT provides a venue for spirited on-track competition with a high degree of both safety and convenience. NASA TT competition will take place during NASA HPDE-4 sessions or in separate TT run groups, depending on the event schedule and number of participants. In addition to having a set of National NASA TT Rules, the rules, safety guidelines, and driving requirements of the HPDE-4 program apply to NASA TT. These rules can be found in the NASA CCR (Club Codes and Regs).
