In November of 1985, Buick presented in SEMA, the Wildcat concept. The car had an engine that was mounted in the middle, just behind the seats, with its design to be very futuristic. Its main feature was the huge glass dome, with its curvy body being made from carbon and its weight reaching just 1,320 kg.
It was equipped with a 3.8-liter V6 engine, which produced 360 hp at 7,000 rpm with 540 Nm of torque at 5,000 rpm, combined with a 4-speed automatic transmission, which was sending the power to all the wheels.
Its interior had a screen in the centre console that showed information such as torque measurement, oil pressure, while it also had a compass. Moreover, the car featured a head-up display that projected on the windshield the selected gear, speed and mileage.
The prototype that was unveiled at SEMA was not functional, but Buick had built a second, fully functional prototype, that was used in a series of tests, but unfortunately they never took the decision to sent it to production.
