Michelin open to F1 comeback – with 18-inch rims

1 Comment

Michelin director Pascal Couasnon says the French tire manufacturer could be open to an F1 return in 2014 – providing the sport changes its wheel rim size.

Strict rules on Formula One wheel sizes force teams to use 13-inch wheels which are considerably smaller than those seen in other racing series. Couasnon told Le Figaro Michelin would prefer to use 18-inch wheel rims if it returned to F1.

This is not the first time Michelin has mooted an F1 comeback but stipulated it must come with a concession on wheel size. It made similar noises in 2010, when Bridgestone was poised to quit the sport, but F1 eventually chose to stick with 13-inch wheels and appoint Pirelli as official tire suppliers.

The obstacles to an increase in wheel rim size are the same now as they were then. The change in size would force a costly re-think of suspension configurations and potentially put gearboxes under greater strain.

Teams are unlikely to swallow such a major shake-up in the technical rules at this late stage in the year. Particularly when they are already grappling with the cost and complexity of the new power trains.

Formula One boss Bernie Ecclestone has ruled out Michelin making a return. He is believed to have signed a new advertising deal with Pirelli which extends beyond the end of this season.

It is the FIA’s decision who will be awarded the F1 tire contract. But it is doubtful a rival constructor would want to supply tires to a series which is already contracted to advertise Pirelli’s product in future seasons.

Toyota victorious in Bahrain on Porsche’s LMP1 swansong

SAKHIR, Bahrain – Toyota denied Porsche a swansong victory in its final LMP1 appearance in the FIA World Endurance Championship by taking a commanding win in the 6 Hours of Bahrain on Saturday.

Porsche started from pole in the last competitive outing for the three-time Le Mans-winning 919 Hybrid car, only to lose out to Toyota’s Sebastien Buemi within the first half an hour of the race.

Porsche lost one of its cars from contention for victory after an errant bollard got stuck underneath Timo Bernhard’s No. 2 entry, leaving Nick Tandy to lead its charge in the No. 1 car.

Tandy moved into the lead just past half distance after a bold strategy call from Porsche to triple-stint the Briton after a fuel-only stop, vaulting him ahead of Anthony Davidson in the No. 8 Toyota.

Tandy’s win hopes were soon dashed when he tangled with a GTE-Am backmarker at Turn 1, sustaining damage that forced Porsche into an unplanned pit stop that put the car a lap down.

With the No. 7 Toyota losing two laps following a clash with a GTE-Pro car earlier on, Davidson, Buemi and Kazuki Nakajima went unchallenged en route to the car’s fifth victory of the season.

Porsche rounded out the podium with its cars, with the No. 2 leading home the No. 1, leaving Toyota’s No. 7 car to settle for P4 at the checkered flag.

Vaillante Rebellion clinched the title in LMP2 after a stunning fightback led by Bruno Senna, with the Brazilian securing his maiden motorsport championship win in the process.

GTE-Pro saw AF Corse complete a hat-trick of titles in 2017, with James Calado and Alessandro Pier Guidi wining the class’ first world championship recognized by the FIA, while Paul Dalla Lana, Pedro Lamy and Mathias Lauda sewed up the GTE-Am title.
