Red Bull launch secretive RB21 ahead of pre-season testing

Red Bull have unveiled their 2025 challenger, the RB21, but have kelp plenty of cards close to their chest before its track debut.

Following Mercedes on Monday, Red Bull have lifted the covers on their 2025 car but fans – and rival teams – will have difficulty making out many differences given the images released by the Milton Keynes constructor.

The RB21 has been shot from a studio at their HQ but Red Bull have dimmed the lights, making it hard to make out any key features as they look to regain their Constructors’ crown.

They have at least given some specifics on the car itself with the RB21 being powered by a Honda RBPTH003 engine. The hearbox is eight-speed, longitudinally mounted with hydraulic power shift and clutch operation. The fuel is Esso Synergy and the pil is Mobil 1.

The brakes are carbon composite discs and pads and the callipers are made by Brembo. The wheel diameter is 18in on the front and rear.
