Ferrari has introduced a new front wing for the US GP, which features a shorter endplate and another aggressively out-turned vane that's anchored to the rear of it (arrowed).

After Ferrari toyed around with a new diffuser concept in the post-Hungarian GP test but failed to race it, the team is set to trial another design in Austin. The revised layout features a flat central section (white arrow), rather than the curved one used previously (see inset). Meanwhile, another vertical fence has been added to the side of the crash structure in order to work the airflow harder and assist the revision below.

Haas has introduced a sizeable update package, which includes the revised bargeboard and new sidepod deflector pictured here. The bargeboard features a series of serrations in the footplate (red arrow), while the deflector (blue arrow) is a horizontally-louvred panel in a similar vein to the appendage used by Ferrari throughout 2017 and recently introduced by Red Bull in Singapore.

Williams continues to optimise the FW40 as the season draws to a close, with the deflectors introduced a few races ago now floated rather than the forwardmost element being anchored to the floor. The team has also revised the floor's axehead inline with these changes in order to bolster performance in that area of the car.

Ferrari returns to a five-slot configuration in the floor deck ahead of the rear wheel in order to quell the effects of tyre squirt. This falls in line with the changes the team has made to the diffuser itself.

Mercedes is seemingly looking to run its conventionally-shaped rear wing for the US GP, rather than the ‘spoon’-shaped wing we’ve seen used previously this season.

The final throes of Brazil's fleetingly successful F1 team

Emerson Fittipaldi is better remembered for his Formula 1 world championships and Indianapolis 500 successes than for the spell running his eponymous F1 team. Despite a hugely talented roll call of staff, it was a period of internal strife, limited funding and few results - as remembered by Tim Wright.

Why McLaren's expanding agenda will benefit its F1 resurgence

In the 1960s and 1970s, McLaren juggled works entries in F1, sportscars and the Indy 500 while building cars for F3 and F2. Now it’s returning to its roots, expanding into IndyCars and Extreme E while continuing its F1 renaissance. There’s talk of Formula E and WEC entries too. But is this all too much, too soon? Stuart Codling talks to the man in charge.

Yuki Tsunoda arrived in grand prix racing amid a whirlwind of hype, which only increased after his first race impressed the biggest wigs in Formula 1.

This is another example of Formula 1 and the FIA scoring an own goal by forgetting what makes motorsport magic, with the Istanbul race winner also a victim of this in the championship’s recent history
