When the opportunity presented itself for Subaru to take Gymkhana over from Ken Block and Ford with the help of Travis Pastrana, the team at Vermont Sportscar and Subaru Motorsport began to build the most intense STI before the ink ran out. dry on contracts. Subaru had a year to develop the car and organize the massive shoot, only to complete the shoot in Pastrana’s hometown of Annapolis in just four days. It’s a narrow window by any standard, let alone with an 862 horsepower STI pushed to unknown limits.
The Gymkhana 11 STI is built from a 2020 Subaru WRX STI body that is cut and drilled with holes for lightness. The end result is more akin to a tubular silhouette racing car, with a flat underbody, full roll cage and the most complex, drift-ready active aero package rallycross experts have ever concocted in the wind tunnel. The body is mostly Kevlar and pre-preg carbon fiber, while the engine uses the powerful, low-stroke crankshaft from the Subaru rallycross car with the larger 2.5-liter block to end up with 2.3-liters. The icing on the cake is the 3D printed Inconel exhaust through the hood.
Building a race car without having to adhere to any rules is every engineer’s dream, and the WRX STI’s longer wheelbase really allowed for better handling, even with nearly 900 horsepower from a flat four. . To deal with the wild horsepower and torque, the gearbox has larger gears, while custom electronics have given Travis Pastrana buttons such as Send It, Shake, and Bake.
Apparently the Bake is for flames, pops and bangs, while Send It optimizes speed and the rear fin for jumps. Despite the furious turbo, the engine has been tuned to provide good handling, which is what you need to perform borderline stunts.
