The engineering team at Red Bull Advanced Technologies faced an unusual problem. They were given a completely blank sheet of paper. For legendary aerodynamicist Adrian Newey’s swansong project, the goal was simple: build an ultra-exclusive, track-only machine that defies modern racing regulations. That vision is becoming reality in Milton Keynes.
The Red Bull RB17 hypercar will hit the tarmac with a clean-sheet, naturally aspirated 4.5-liter V10 engine that revs to an ear-splitting 15,000 rpm. Built by Cosworth, this bespoke powertrain generates 1,000 horsepower entirely on its own. Add in a 200-horsepower electric motor, and total system output reaches a blistering 1,200 horsepower and 811 pound-feet of torque. But arriving at this exact engine configuration took serious debate.
Cosworth Managing Director Bruce Wood recently detailed the grueling decision process. The team originally conceptualized the car with a twin-turbo V8. They also heavily analyzed V6 turbos and V12 setups before finally settling on the V10. Why? Weight and speed. The V10 allowed them to hit the aggressive 15,000 rpm target without exceeding a strict 150 kg engine weight limit.
Having zero restrictions actually threw the engineers a curveball. Wood noted that the complete absence of FIA racing regulations or street-legal emissions constraints made the design process surprisingly difficult. Without an established rulebook to push against, crystallizing their initial ideas felt like trying to anchor a ship in open water.
Because the RB17 bypasses both strict homologation racing formulas and Euro 6 standards, Newey and Cosworth had unprecedented engineering freedom. They integrated active aerodynamics and active suspension systems that are explicitly outlawed in modern Formula 1 grids. The result is a car capable of pulling lateral loads exceeding 5G, cementing its extreme F1 connections and track-only specifications.
Production is strictly capped at 50 units. While it is engineered exclusively for closed circuits, third-party modifiers like Lanzante are already exploring expensive aftermarket conversion kits to make the RB17 road-legal in the UK.
How Unregulated Engineering Outpaces Formula 1
Red Bull is selling a driving experience that literal Formula 1 drivers are no longer allowed to have. The RB17 utilizes Air Valve Spring (AVS) technology directly mirroring the Cosworth TJ2005 V10 engine from Red Bull Racing’s 2005 debut F1 car. By ignoring modern rulebooks, the vehicle instantly reframes its competitive positioning against the Aston Martin Valkyrie and the Mercedes-AMG One. While rivals compromise output to maintain street legality, Red Bull built a time machine to the high-revving era of motorsport.
