V8Star used a mono type tubular chrome-molybdenum steel chassis equipped with 5.7-litre V8 engine. The engine, tuned by Jack Roush, was a lightweight aluminium block unit weighing about 200 kg. Originally the engines produced 445 hp of power, but they were tuned up to 495 hp at 6,500 rpm and 600 Nm at 4,850 rpm for the second season.
The cars weighted 1,295 kg, of which 90 kg was a fibreglass-reinforced plastic silhouette. The silhouettes represented seven different saloon cars. All of them were 1.92 m wide and 1.36 m high. Rear wings, rear diffusers and front spoilers were adjusted in wind tunnel in order to make each body style equal. The silhouettes resembled Audi, BMW, Ford, Jaguar, Lexus Opel and Volkswagen models but were unbranded, as none of the manufacturers were involved in the series.
The cars had independent, double wishbone suspension in front and rear. Wheels were 18 inches in diameter. Slick Goodyear control tyres were 12 inches wide in front and 14 inches in rear.
