1985 Buick Wildcat IV
Buick brought this radical concept to the '85 SEMA show in Vegas. This was the 4th out of 5 Buick concepts dubbed the Wildcat. There were 3 made in the '50s, this one in '85, and then one in '97.
Two cars were actually built. The first one, brought to the SEMA show, was a non-functioning concept. The second, however, was a fully working model used for engineering tests. This car may have been a preproduction car used for development, but other sources claim this car was only a testing bed for Buick's ideas. GM still owns the operational concept car.
While many Buick concept cars emphasized expressive styling, the Wildcat turned the spotlight on performance and Buick’s signature V-6 engine.
The Buick V-6 was the centerpiece of the division’s motorsports program in the ’80s and ’90s. The Wildcat took performance to the next level with four-wheel drive and a rear-mounted engine prepared by noted racing specialist McLaren Engines. Based on Buick’s 3.8-liter V-6 block, the experimental powerplant has 24 valves, dual overhead camshafts and programmable sequential-port fuel injection. The formidable V-6 is visible through an opening in the Wildcat’s rear deck.
