Over 17 years coming, 1990 Audi Coupe Quattro includes Bluetooth drive-by-wire and rare body kit, potential to make 1,200 horses.
Over 17 years ago, Hoonigan Industries co-founder Brian Scotto purchased a 1990 Audi Coupe Quattro, with the intent of one day running up a few hills. Other projects and life in general took his attention away from the Audi,though. Then, Toyo Tires called.
Scotto’s Audi Coupe Quattro debuted at SEMA 2021 at the Toyo Tires Treadpass booth alongside Ken Block‘s Sport Quattro. Though only “SEMA-ready” at the time of filming, Scotto was only happy to talk about the “completed” project with fellow Hoonigan Ron Zaras about the build.
“To start, it’s a 1990 Audi Coupe Quattro,” said Scotto. “What makes it so wild right now is the Prior Design kit. Based out Germany, they normally do Lamborghinis and stuff. Decided they wanted to build a crazy kit for the Coupe Quattro, of all cars […] This is actually number nine of 40. It’s a limited-edition kit. Looking at it, it adds a lot.”
Including tons of functionality. The main purpose of the Prior Design kit is to allow Scotto to run wide Toyo R888s for improved control and grip up those mountains; the Sport Quattro-style ventilation and more aggressive appearance are bonuses. Each R888 surrounds an 18×12-inch Audi Tradition hollow-spoke magnesium wheel, inspired by the Group B Quattro’s 15-inch Rotiforms.
“I’m big, right?” asks Scotto. “Six-foot-eight. I needed to fit in this car with a helmet, and be able to pass tech. Which means I need about two inches of clearance from the top of my helmet to the bottom of the roll bar. That’s a really difficult thing to do.”
The first part was finding a seat with a halo suitable for Scotto’s build. Sparco happened to have just the thing with their Pilot, “the tallest seat in the game right now” without building a custom seat. Meanwhile, the cage was welded as close to the Audi’s interior frame as possible, maximizing room for Scotto. Built to American Rally Association specs, the cage ensures Scotto gets to go home to his kid.
“Bluetooth everything,” said Scotto. “There’s no wiring. Coil pack, injectors, everything is Bluetooth. I don’t even run an ECU; it’s all cloud-based now.”
The rest of the Audi’s sorcery comes from a 3B 2.2-liter inline-five from an Audi 200. Currently linked to a six-speed from an S4, the I5 stroker is now 2.6 liters; it’ll soon have a dog box with paddles, though. Next to it is a shared footprint turbo, allowing Scotto to run six different size turbos in one location. Current output is up to 750 horsepower. However, with the right turbo, the I5 can send up to 1,200 horses to the corners.
