The McLaren MP4/1 (initially known as the MP4) was a Formula One racing car produced by the McLaren team. It was used during the 1981, 1982 and 1983 seasons. It was the second Formula One car to use a monocoque chassis wholly manufactured from carbon fibre composite, after the Lotus 88 that debuted at the 1981 US Grand Prix West, a concept which is now ubiquitous. The MP4/1 was first entered in a Formula 1 race at the third grand prix of the season in Argentina.

From 1981 until late 1983 the MP4/1 was powered by the 3.0 litre Ford-Cosworth DFV V8 engine, but in late 1983 the team switched to turbocharging, using a 1.5 litre TAG V6 engine built by Porsche.

Niki Lauda was a three-time F1 World Drivers' Champion, winning in 1975, 1977 and 1984, and is the only driver in F1 history to have been champion for both Ferrari and  McLaren, two of the sport's most successful constructors.

The McLaren MP4-20 is a Formula One racing car that was built by McLaren for the 2005 Formula One season. The chassis was designed by Adrian Newey, Paddy Lowe, Pat Fry, Mike Coughlan and Peter Prodromou with Mario Illien designing the bespoke Ilmor engine. The car was driven by Kimi Räikkönen and Juan Pablo Montoya. The MP4-20 was the last McLaren car to be powered by Mercedes-Benz under the Ilmor partnership since the 1995 season. The car's chassis was an almost completely new design after the failure of the MP4-18 and MP4-19. 

This would be McLaren's last car to feature the grey and black livery of primary sponsor West cigarettes, a partnership which began with the MP4/12 in 1997.

The McLaren MP4-27 is a Formula One racing car designed by Vodafone McLaren Mercedes for the 2012 Formula One season. The chassis was designed by Paddy Lowe, Neil Oatley, Tim Goss, Andrew Bailey and John Iley and was powered by a customer Mercedes-Benz engine. The car was driven by former World Champions Jenson Button and Lewis Hamilton. 

This was the last McLaren car that Lewis Hamilton drove for the team, as he moved to the Mercedes AMG Petronas F1 Team in 2013. This was also the last McLaren Formula One car to win a race until the McLaren MCL35M did so in 2021. The car achieved 7 wins, 8 poles and third place in the Constructors' Championship in 2012.

The McLaren MP4-31 is a Formula One racing car designed by McLaren to compete in the 2016 Formula One season. The car was driven by 2005 and 2006 World Drivers' Champion Fernando Alonso and 2009 World Champion Jenson Button, and reserve driver Stoffel Vandoorne, who replaced Alonso at the Bahrain Grand Prix following the Spaniard's accident at the Australian Grand Prix which deemed him unfit for the next event.

The car used the Honda RA616H power unit, the second engine developed by Honda since their return to the sport with McLaren in 2015.

The MP4-31 is the final McLaren to use the "MP4" prefix following CEO Ron Dennis's departure from the team, and also final McLaren car to use ExxonMobil fuel and lubricant since the transfer of ExxonMobil sponsorship to Red Bull Racing in 2017.
