The Buick Blackhawk  is a retro concept 2+2 convertible built by Buick in 2001. Its grille is based on 1939 Buicks and the concept car Buick Y-Job, while its main body is based on the 1948 Buick Roadmaster. It features a retractable hardtop, shaved door handles, and hidden headlights.
The Blackhawk is powered by a 1970 455 in³ (7.5 L) Buick GS Stage III V8, producing 463 hp (345 kW) at 4600 rpm and 510 lb·ft (690 N·m) of torque at 4200 rpm and accelerating the car from 0–60 mph (0–97 km/h) in under five seconds. The engine is mated to an electronically controlled four-speed automatic transmission.
The vehicle is entirely handmade, especially the carbon-fiber top and the frame. The retraction system is also handmade. The Blackhawk also features a fully independent suspension, keyless entry, and dual exhaust with 3 in (7.6 cm) pipes. The vehicle also has 18 in (46 cm) five-spoke alloy wheels with high-speed Z-rated tires. GPS is also provided. The interior is based on the 1996 Buick Riviera.
The car was featured in the film "Bad Boys II". It was driven by actor Will Smith after the mortuary scene.
