Williams remove illegal exhaust from FW35

1 Comment

After protests from many of their rival Formula One teams, Williams have decided to change the design of their exhaust system to meet FIA regulations.

Having unveiled their car at the second test in Barcelona, attention was drawn to the design of the exhaust on the FW35, with Caterham’s similar design also coming under close scrutiny.

The exhaust appeared to contain turning vanes within the coanda tunnel. These are outlawed by the FIA, who inspected the car at the first test in Barcelona nine days ago. Not wishing to bring their new car into disrepute, Williams have elected to revert to a vane-free exhaust.

Talking to Autosport, Williams’ chief engineer Xevi Pujolar confirmed the move.

“Yeah, we have made some modifications and now it is finished. We have changed it and that is it.”

It was a radical move by the team, especially given the reaction to Caterham’s exhaust design at the first test in Jerez. Over 80% of the car was redesigned for 2013, and it appears that the changes have been fruitful following Valtteri Bottas’ good showing in Barcelona today. The flying Finn spoke to his team following the session about his progress.

“It was a good day overall and we had no problems with the car.

“It’s a shame we were disrupted a bit by the wet weather, although this did allow us to run on the wet, intermediate and dry tires.”

Williams will be looking to bridge the gap to the front runners in 2013, building upon their 2012 success that saw Pastor Maldonado take their first win in seven years at the Spanish Grand Prix. By clearing their new exhaust with the FIA, they will not face any uncertainty heading to the Australian Grand Prix on March 17th.

Save for two occasions, in 2006, and 2010, the Australian Grand Prix has served as the season-opening event for the FIA Formula 1 World Championship since 1996, and this weekend’s event will be the 21st time that the city of Melbourne has kicked off the Formula 1 campaign.

The 2018 season is the fifth one of the current hybrid power unit era, the second season of the current aero regulations, and the second under Liberty Media’s guidance.

Last year saw titans Mercedes AMG Petronas and Scuderia Ferrari duel for supremacy for most of the season before Mercedes distanced Ferrari late in the season to take the constructor’s title and the driver’s title, with Lewis Hamilton, who is now tied with Sebastian Vettel on four world championships apiece.

Four drivers on the grid have Formula 1 world championships to their name: Hamilton, Vettel, Kimi Raikkonen, and Fernando Alonso. Scuderia Toro Rosso’s Brendon Hartley also has a world championship to his name as a two-time titlist in the FIA World Endurance Championship.

So, what can viewers expect from the 2018 curtain-raiser in Australia? A handful of things to watch are below?

2018 Australian Grand Prix – Talking Points

Does Anyone Have Anything for Mercedes?

Only on one day during pre-season testing did a Mercedes driver lead the way – Lewis Hamilton was fastest on the final day of Week 1 at the Circuit de Barcelona-Catalunya.

However, all indications were that was by design, with the team focusing the majority of the second week, if not the entire second week, on long runs with their W09 EQ Power+ chassis.

Such a decision is an ominous one, in that it indicates the team is very comfortable with the amount of speed in the car and did not see a need, or desire, to show their hand during testing.

With that in mind, the Mercedes duo of Hamilton and Valtteri Bottas may yet again have the best and fastest cars, and the team looks poised to potentially make it five constructor’s and driver’s championships in a row.

Ferrari and Red Bull Look to End Mercedes Reign

The biggest threats to Mercedes are undoubtedly Ferrari and Red Bull, the only other teams to win in 2017.

And both teams displayed a lot of pace during testing, particularly in the “one-lap speed” category. Ricciardo set a lap record around the Catalunya circuit during the second week, only for Vettel to supplant that mark later in the week. Teammate Kimi Raikkonen led the way during the final day of testing.

It is unknown how that pace will translate over the course of a race distance. Mercedes appeared to have an edge on both Ferrari and Red Bull over long runs and race simulations, but there is also a theory that neither Ferrari nor Red Bull had their true long-run form on display.

Still, if a team is going to knock off Mercedes, it will likely be either Ferrari or Red Bull.

McLaren on the Rebound?

Put simply, the previous three seasons for McLaren F1 Team were a bit of a disaster. Their partnership with Honda yielded point totals of 27 (2015), 76 (2016), and 30 (2017) in a three-year venture that was defined by poor reliability and underwhelming power.

The relationship hit a boiling point last year and both entities parted ways ahead of the 2018 season, with McLaren signing a new power unit deal with Renault.

Testing went better than in previous years, though the team continued to battle reliability problems. However, all issues appeared to be minor, needling issues rather than more significant, foundational problems, as the other Renault teams (Red Bull and Renault Sport F1 Team) had solid runs with few reliability issues.

The car does appear to have speed in it, so if the reliability problems are behind them, McLaren could be in for a rebound season.

Stuck in the Midfield Again

Formula 1’s battle amongst the midfield is set to be as fierce as ever as a host of a several teams have a chance at being “best of the rest.”

Sahara Force India has been the frontrunner from the the midfield teams each of the last two years, finishing fourth in the constructor’s title in both 2016 and 2017, though if the steady conflict between drivers Esteban Ocon and Sergio Perez continues through 2018, it could hamper their efforts significantly.

Renault Sport F1 Team and Haas F1 Team look to improve on their 2017 form, while Toro Rosso is in a new partnership with Honda power units…and has experienced a surprisingly smooth pre-season as Honda’s 2018 platform looks significantly better, with the team enjoying a solid run of testing with few, if any, reliability problems.

Williams Martini Racing and Alfa Romeo Sauber appear to be at the back of the pack entering the season, but both could battle for points finishes if those ahead of them falter.
