This is a blast from the past. An 850-hp Buick Riviera took the top hot rod honors at the Detroit Autorama. Alex Lloyd.
Losing its four-seat capability, the award-winning Riviera makes do with two, featuring a 6.2-liter GM-sourced LS-series engine, good for 850 hp thanks to its twin-turbos. Power to the rear wheels arrives via a six-speed manual transmission. The waste gates and turbos are located in the trunk, with heat vents blended into the rear tail lamps. The front fenders feature additional venting, along with a hot-air exit in the hood. It’s far from the stock Riviera it once was, but to win this prize, that’s a necessity.
