The car was based on second-hand Tatra 613-2 model, which was originally modified by AMK Narex (since 1992 Narimex) who specialized in rescue operations. This business had been set up by former racer, Cyril Svoboda, who was notorious for having adapted a Lancia Beta for rescue duties.
Because of the need of organizers for a car capable of keeping up with F1 cars on the opening race, the then T-623 was further developed into the 2-seat, lightweight and more powerful T-623 R. And it led to a fleet of eight cars being used in Formula One as a safety cars at the inaugural 1986 Hungarian Grand Prix. The latest Hungarian Grand Prix that T-623 R was participated was held in 1995.
The car now featured a 3.8-Litre V8 engine producing over 300 horsepower, and was capable of a top speed 250 km/h. Its features included: a removable steering wheel and racing seats; adjustable and lowered suspension; upgraded braking system and tyres. Its aluminum fenders, hood, and doors, plus plexiglass windows, contributed to a kerb weight of 1270 kg or a significant weight reduction of 350 kg (771 lbs).
