Mercedes lead Madrid F1 upgrades as teams brace for fresh challenge

Several F1 teams have brought new parts to their cars for the Spanish Grand Prix as they look to enjoy a successful weekend around the new Madring Circuit.

Fresh from its victory last time out at Monza, Mercedes has arrived at the event with some circuit-specific upgrades.

These are found at the rear of the car, with modifications made to the rear wing and exhaust tailpipe to reduce drag.

It has also noted a reprofiling of the front lip around the brake drums, as the Brackley-based squad hunts for its 10th victory of the season.

At Red Bull, the team has battled concerns with its car in recent times, with Max Verstappen noting at Monza that the car was degrading throughout the race.

In an attempt to fix the concern, the Milton Keynes-based squad has introduced changes to the rear wheel bodywork assembly and a geometric change between the floor and chassis.

Ferrari has listed just one upgrade, a reprofiling of the rear top wishbone of the suspension to improve local load.

Likewise, McLaren's has just a sole modification to the car, focused on the rear wing to improve airflow.

Across the midfield teams, upgrades are a lot more scarce.

After taking pole position last time out at the Italian GP, Alpine has brought an updated floorboard to Madrid, while Cadillac has made changes to its rear wing and diffuser.

Williams, Racing Bulls, Aston Martin, Haas and Audi have all arrived at the race with no notable upgrades.
