The Alfa Romeo Proteo concept car was released at the Geneva Motor Show in 1991. It is a 2-door coupé cabriolet (folding roof) featuring a 3.0 liter quad-cam 24-valve (2959 cc), 60 degree V6 coupled with a 5-speed manual transmission, with a top speed of 250 km/h (155 mph). The engine used in Proteo produces 260 PS (191 kW; 256 hp). The Proteo uses shortened floorpan used in Alfa Romeo 164 and features four wheel drive and steering. Many of the Proteo's design cues were influenced by the Alfa Romeo 916 series GTV/Spider, which was designed in July 1988.
