The most famous motor racing outfit has unveil their 2015 challenger with the SF15-T.

Ferrari hopes that this new Formula 1 car can get back into the winning circle thanks to a driver line-up in the shape of Sebastian Vettel and Kimi Raikkonen.

After a disappointing 2014 season that has prompted a major management and staffing overhaul, the Maranello-based outfit is determined that the changes it has made will help move it back up the grid.

The James Allison-designed SF15-T features a long protruding nose and an aggressive sidepod concept.

Allison has commented that the main focus from the team is to resolve the issue regarding the “unacceptably large gap in our performance” last season, when Ferrari failed to win a race for the first time since 1993.

“We’ve tried to make sure the weaknesses we felt were particularly notable on the ’14 car were put right for the ’15 car,” he said.

Allison added that the team have made major gains with the packaging of the car at the rear.

“The back of the car is something that is noticeably different from the 2014 car where we have been successful in pulling the bodywork much tighter to everything underneath the skin,” he explained.

“That’s been done through a lot of work not just in the wind tunnel but also in the design heart of the company to try and find radiator designs that were fundamentally more efficient. So for every square centimetre of radiator we’re able to extract more cooling this year than last and therefore able to close the car down at the back significantly.”

The front of the SF15-T features a long, smooth nose which is familiar from other designs which have already appeared following another change in the regulations.

“I think all the cars on the grid this year are going to be more appealing around the front,” said Allison, “because after after a few years of trying I think we’ve finally invented a regulation that gets what we wanted from a safety point of view but also doesn’t create the rather unappealing features of the last few years”.

“So I think everyone will look a lot prettier from the front and the 2015 Ferrari is, I think, nice in that regard.”

New signing Sebastian Vettel will be given the unique opportunity to shakedown the car in the first official run at Jerez.

This is the new bold look for Sauber. The familiar fifty shade of grey over the last couple of seasons has been replaced by blue as the team unveiled images of its new C34 online.

Following a disappointing 2014 Formula 1 campaign, where it failed to score a single world championship point, the Swiss-based outfit is hoping it can rediscover the form that had it fighting for podiums in previous seasons.

Sauber has opted for a fresh new look for the 2015 championship ahead, with its colour scheme switching from white and grey to blue and yellow.

The Ferrari-powered car also has a striking nose design – featuring a more rounded front edge than seen on the other 2015 cars so far.

Sauber’s design team has focused on three areas for improvement over last year’s car: better performance in slow-speed corners, weight reduction and improved braking stability.

The car features slimmer sidepods compared to the C33, and the team has overhauled its radiator concept and now mounted them horizontally.

Packaging around the rear of the car is much tighter, and Sauber’s quest to get under the weight limit to allow maximum ballast has been boosted by the raising of F1’s minimum weight limit to 702kg.

The team also has an all-new driver line-up for 2015, as Marcus Ericsson joins Formula 1 rookie Felipe Nasr in place of Adrian Sutil and Esteban Gutierrez.

Ericsson will be the first man to drive the car when he takes to the track at Jerez on Sunday.

Sauber plans to use an interim version of the car for the first test, which will include some parts still from the C33. These will be replaced with bespoke 2015 components ahead of the season.

The 2014 Formula 1 champions provided a sneak view of their new race car during a shakedown test with the W06 Hybrid at Silverstone.

Mercedes hopes that this new car can defend their constructors’ title as well as giving the chance for Lewis Hamilton to seek his third drivers’ championship.

These images were provided by the outfit’s social media channel as Mercedes conducted a filming day with Nico Rosberg and champion Hamilton behind the wheel.

The W06 Hybrid covered 18 laps in icy conditions at the home of British motor racing.

Mercedes will officially launch the 2015 challenger on the first day of pre-season testing at Jerez on February 1.

The famous Formula 1 team and motor manufacturer are reunited for the upcoming season. This is the new McLaren-Honda MP4-30 which was unveiled on the team’s social media network.

The Woking-based outfit hopes that progress in its design structure, as well as its new relationship with Honda, can help Jenson Button and Fernando Alonso move back to the competitive end of the grid.

The silver, red and black race car features a long low nose design without the thumb extension seen on the Williams FW37 – and a tightly packaged rear end around the new power unit.

It also features a split roll-hoop inlet. The MP4-30 has been heavily influenced by chief engineer Peter Prodromou, who arrived at McLaren from Red Bull Racing.

Honda is returning to Formula 1 after a six-year absence, and is renewing a relationship with McLaren that delivered multiple victories and world titles from 1988 to 1992.

Honda’s motorsport chief Yasuhira Arai said that the design of the MP4-30 was one of no-compromise as the Japanese manufacturer bid to make a success of its return.

“As you can see with the new MP4-30, we’ve dedicated ourselves as one team with McLaren to creating a new car that compromises on nothing – either power or aerodynamics,” he said.

“Yet, in the midst of the excitement, both myself and our engineers are 100 per cent focused in both Sakura and Milton Keynes to prepare for Jerez and beyond. We’re confident that the technology is there, and I’m looking forward to see how it will perform.

“We’re about to commence a long season, with numerous challenges, but Honda is determined to face them head-on. After all, we’re here to drive Formula 1’s technology forward and give our fans a thrilling ride.”

With Fernando Alonso back to McLaren after a period with Renault (2008-2009) and Ferrari (2010-2014), the double world champion hope that this car can deliver that third title. As for Jenson Button, this is a great opportunity for him to remain commitment to the sport despite the off-season rumors of retirement.

It’s going to be a fascinating to see if this experience world champion partnership, along with the Honda engine, will return back to the glory days. Huge expectations is on everyone at McLaren to succeed and win that elusive championship this season.

Lotus F1 became the third team to unveil their 2015 challenger by releasing images of the new Mercedes-powered E23 Hybrid via social media.

The Enstone-based outfit are hoping that this new car will a be more competitive following a disappointing 2014 championship. A switch to a new engine manufacturer is certainly a positive step.

In addition, Lotus has spend much of last season consolidating its finances and restructuring its technical organisation so as to ensure that it returned to form this year.

The E23 Hybrid looks very beautiful, especially the front nose. This is a major contrast to that ugly and now-outlawed twin-tusk concept in 2014.

Lotus technical director Nick Chester described the car, which will be powered by Mercedes’ V6 hybrid turbo, as “a massive step forward”.

“It’s no secret that we struggled with last year’s car so we’ve targeted every area that caused us an issue,” he said. “We’ve made strong progress in the wind tunnel as well as in areas such as packaging and cooling.”

“We expect the E23 to perform far, far better than its predecessor.”

Chester said the new power unit “looks to be the one area of the car which could bring us the greatest performance gain”.

“It’s not just performance, but reliability and driveability as well as packaging and cooling too,” he explained.

Romain Grosjean and Pastor Maldonado have been retained for another season while the first shakedown of the new car will take place at Jerez, as part of pre-season testing.

Fingers crossed the E23 goes as quicly as it looks at the race tracks this season.
