The evidence that dismisses Haas-Ferrari F1 2018 critics

Force India and McLaren called for an investigation into the Haas-Ferrari collaboration to ensure the restrictions put in place on aerodynamic development are being adhered to.

However, as Craig Scarborough explains on Motorsport.tv's Motorsport Show, there are clear differences between the Ferrari SF71H and the Haas VF-18.

"The performance of a Formula 1 car is down to the aero and the aero on the Haas is significantly different," said Scarborough.

"You're looking at areas like the bargeboards, the X-vanes - these shutter-like things that go up the side of the sidepods - they're very different from the Ferrari's.

"Even the halo treatment is completely different to Ferrari's with all these little vortex generators above and below it.

"It's just an independent project. You can find things that are similar to the Ferrari but equally you can find Ferrari ideas on the Mercedes, the Red Bull, up and down the grid."

Scarborough also explores the "unusual" scenario of mistakes being made in both pitstops, after Kevin Magnussen and Romain Grosjean were forced into retirement with improperly-fitted wheels after running fourth and fifth in the opening stint.

"The wheel already has the wheelnut spinning inside it," he explains. "You've got to get that wheel perfectly lined up over the axle.

"Then, when the wheel gun comes in if the nut tightens up, everything tightens up.

"But if that wheel is slightly misaligned and the nut starts to be tightened by these really powerful wheel guns, it's just going to chew the nut over the thread and the whole thing won't connect properly."
