The other TLX is a TLX GT. This is the type of car from which the A-Spec borrows engine components, but not the TLX GT's twin-turbocharger system. TLX GTs have already been competing in motorsports, specifically in the Pirelli World Challenge. Acura did make some changes to this car for Pikes Peak, though. The suspension and engine computer have been tweaked, gear ratios shortened, and additional aerodynamic bits added for more downforce. The TLX GT will compete in the open class.
Despite the focus on the TLX, Acura is still bringing an NSX to the hill climb. This car is similar to the one that raced in the Time Attack 1 class last year, but has some changes for the Time Attack 2 class. Most notable of these changes are the massive rear wing and front splitter. According to Acura, these aerodynamic aids were based on those used for the NSX GT3 race car. Acura also reduced weight, changed the tuning on the engine computer, and fitted sticky R-compound tires.
