600+hp Coloni C4 12,000rpm F1 Sound (Cosworth DFR 3.5 V8)

Here's some footage of a 1989 Coloni C3 and a 1991 Coloni C4. Both of these formula one cars are powered by the 3.5 litre naturally aspirated DFR V8 engine, built by Cosworth. The DFR produces approximately 630 bhp. The best thing: these engines rev up to 12,000 rpm! Doesn't it sound wonderful? Event: 2018 Historic Grand Prix (Zandvoort, The Netherlands).
