Modern Formula 1 engines are engineering marvels that can produce over 1,000 horsepower from just 1.6 liters of displacement. Relying on technologies such as turbocharging, and a hybrid-electric powertrain (MGU-H and MGU-K), another fascinating element of these engines is their lack of traditional valve springs. First introduced by Renault in the Lotus 98T driven by Ayrton Senna and Johnny Dumfries, pneumatic valve springs have allowed F1 engines to rev higher, make more power, and are still in use today. In this video, we’ll explore why they were invented, how they work, as well as the advantages and disadvantages of their use.
