F1 2018 new cars picture special: all now revealed

With just over a month until the 2018 Formula 1 season begins in Australia on March 25, the teams are just about to hit the track for testing with their 2018 machines.

While F1's new owners are making substantial changes to how the sport is presented, the technical rules are relatively stable this year – although there are a couple of notable new regulations that will affect how the cars look.

The most visible change is the introduction of the ‘halo’ cockpit protection device, a wishbone-shaped frame designed to protect drivers from debris. While the halo’s looks have attracted criticism from some, F1 tech chiefs have also moved to tidy up the cars in another area, banning the ‘sharks fins’ and small wings on engine covers.

Check out our gallery featuring all the 2018 cars that have been launched so far. We’ll be updating it with more cars as they are unveiled.

McLaren F1 Team

McLaren MCL33

2 Stoffel Vandoorne (BEL)

14 Fernando Alonso (SPA)

What’s new: This is a huge season for McLaren. The team hasn't won a race for six years or even scored a podium for four years, during a nadir in the team's history as a result of the laggard Honda power unit. For 2018, McLaren has switched to Renault power and is expecting to be back at the sharp end of the field as a result. There's also a new livery for the new era, with the return of McLaren's historic Papaya colour. The driver line-up remains unchanged, although Alonso will also be competing in WEC this year.

Mercedes AMG Petronas Motorsport

Mercedes F1 W09 EQ Power+

44 Lewis Hamilton (GBR)

77 Valtteri Bottas (FIN)

What’s new: Mercedes-AMG has dominated Formula 1 since the hybrid era began in 2014. Although Ferrari and Renault claim to have made powertrain gains over the winter, there's a fair chance this will continue, especially if four-time world champion Hamilton remains at his best. This is a make-or-break season for 28-year-old Bottas, after a sub-par 2017 and with a fair few big names becoming free for 2019.

Scuderia Ferrari

Ferrari SF71H

5 Sebastian Vettel (GER)

7 Kimi Räikkönen (FIN)

What’s new: Ferrari are expecting to further close the gap to leaders Mercedes after lead driver Vettel ran Hamilton close throughout 2017. Ferrari's two-champion driver line-up remains unchanged for what will be 38-year-old Räikkönen's swansong season. In terms of the car, Ferrari has returned to an all-red livery for the first time since 2009 following the loss of main sponsor Santander.

Aston Martin Red Bull Racing

Red Bull Racing-TAG Heuer RB14

3 Daniel Ricciardo (AUS)

33 Max Verstappen (NED)

What’s new: Aston Martin has become Red Bull's title sponsor, one element of a partnership that has already resulted in the Adrian Newey-designed Valkyrie hypercar. The team has launched the RB14, powered by TAG Heuer-branded Renault engines, with a ‘camouflage’ livery. The full 2018 paint scheme is to be unveiled before pre-season testing begins.

Haas F1 Team

Haas-Ferrari VF-18

8 Romain Grosjean (FRA)

20 Kevin Magnussen (DEN)

What's new: American squad Haas has a stable line-up for its third season. After inconsistent form during 2017, the Ferrari-affiliated team has focused on trying to make its VF-18 more stable and predictable, with a particular focus on aerodynamics and weight reduction.

Renault Sport Formula One Team

Renault R.S.18

27 Nico Hülkenberg (GER)

55 Carlos Sainz Jr. (SPA)

What’s new: Renault has been very clear about its ambition to return to the top of Formula 1 and is thus expecting to further the improvement it showed throughout the 2017 season. The driver line-up looks promising, too, with 23-year-old Sainz spending his first full season at Enstone alongside solid veteran Hülkenberg, having replaced the lacklustre Jolyon Palmer for the last four races of 2017.

Williams Martini Racing

Williams-Mercedes FW41

18 Lance Stroll (CAN)

35 Sergey Sirotkin (RUS)

What’s new: Felipe Massa has retired from F1 (for good, this time), and after testing both Robert Kubica and Paul di Resta, Williams signed Sergey Sirotkin to drive its Mercedes-powered FW41 for the 2018 season. The move has been criticised due to the Russian’s pay driver status, although he's hardly without talent, having finished third in the GP2 Series championship in both 2015 and 2016.

Alfa Romeo Sauber F1 Team

Sauber-Ferrari C37

9 Marcus Ericsson (SWE)

16 Charles Leclerc (MON)

What’s new: After withdrawing from a deal to switch to Honda engines for 2018, Sauber will continue to run Ferrari powerplants – and will have closer ties to the FCA Group thanks to new title sponsorship from Alfa Romeo. As well as returning Alfa logos to the grid for the first time since 1987, the deal also means Sauber will run Ferrari’s top junior driver, reigning Formula 2 champion Charles Leclerc.

Red Bull Toro Rosso Honda

Scuderia Toro Rosso-Honda STR13

10 Pierre Gasly (FRA)

28 Brendon Hartley (NZL)

What’s new: Red Bull's junior squad will be nervous heading into 2018, having (for very protracted reasons) swapped Renault powerplants for the lame duck of Honda. However, the Japanese manufacturer is expecting big gains in both performance and reliability to keep Toro Rosso's pairing of full-season debutants, 22-year-old Gasly and Le Mans-winning Hartley, competitive.

Sahara Force India F1 Team

Force India-Mercedes VJM11

11 Sergio Pérez (MEX)

31 Esteban Ocon (FRA)

What’s new: Force India has given F1 fan something to smile about in recent years, by competing at a level well beyond what its budget suggests. The talented driver line-up from last year remains – hopefully with less crashing between them this year – as does Mercedes power and a refined version of the fantastic pink livery. Legal troubles for the team's owner and several prospective buyers circling suggest that the team could have a different name come the first race.
