The McLaren MCL33 is a Formula One racing car designed and constructed by McLaren to compete in the 2018 FIA Formula One World Championship. The car is driven by two-time World Drivers' Champion Fernando Alonso and Stoffel Vandoorne, with additional testing and development work carried out by reigning European Formula 3 champion Lando Norris. The MCL33 is the first car built by McLaren to use a Renault engine after the team terminated its engine supply deal with Honda after three years. It made its competitive début at the 2018 Australian Grand Prix.
The car was launched with an orange and blue livery designed as a tribute to some of the team's earliest cars.
Design and development
Engine supply
In September 2017, McLaren terminated their partnership with Honda, citing Honda's repeated failure to supply a reliable and competitive power unit as being behind the decision to end the partnership. During negotiations to secure a new supplier, Renault disclosed that they did not have the capacity to supply McLaren whilst meeting their commitments to customer teams Red Bull Racing and Scuderia Toro Rosso. As part of the agreement between Renault and McLaren, Toro Rosso ended their relationship with Renault and instead acquired Honda engines, freeing up the existing Renault supply chain for McLaren and allowing Renault to supply the team with their 2018-specification engine, the Renault R.E.18.
Chassis design
The decision to change from Honda to Renault engines brought with it several challenges for the design team led by McLaren technical director Tim Goss. Where the Honda engine featured the turbocharger mounted to the back of the engine, the compressor at the front and the Motor Generator Unit-Heat positioned in the V shape of the cylinder bank, the Renault R.E.18 engine included all three components attached to the rear of the engine and thus required McLaren to change their design approach. In order to accommodate the R.E.18, McLaren had to redevelop their engine bay, gearbox and the rear suspension geometry. The R.E.18 engine allowed the team more flexibility with the size and position of the fuel cell and better aerodynamic performance from the bodywork around the engine bay, but required the team to elongate the gearbox and revise the onboard mounting points for the rear suspension in order to fit the engine.
The changes required to accommodate the R.E.18 allowed McLaren to develop a radical design to the rear suspension geometry. The design combined all of the upper elements of the suspension into a single piece, thus minimising the amount of bodywork in a key area of the chassis and in turn reducing drag whilst giving the team a greater degree of control over air flowing over the rear diffuser and producing more aerodynamic grip.
The switch to Renault engines resulted in some problems for the team. During pre-season testing, the MCL33 was observed to have burn marks on the rear of the engine cowling caused by the tight packaging and insufficient cooling for the peak engine temperature. The team introduced a temporary cooling package for the duration of the test ahead of a planned update to the car's bodywork, and later expressed confidence that the engine reliability issues had been resolved.
Mandated changes
Following changes to the sport's technical regulations, the MCL33 features the "halo" cockpit protection device, a wishbone-shaped frame made of titanium that is mounted above and around the driver's head and anchored to the monocoque forward of the cockpit which is designed to improve safety by deflecting debris away from the driver. The final version of the halo weighed several kilograms and forced teams to extensively modify the chassis. Teams reported that the reinforced chassis needed to withstand the equivalent weight of a London bus in order to pass the mandatory crash tests.
The "shark fin", a carbon fibre panel extending backwards from the engine cowling was removed after McLaren lobbied to the FIA to have it written out of the technical regulations. The MCL33 was launched with a carbon fibre fin running perpendicular to the engine cowling from the airbox to the exhaust. The "t-wing", a thin horizontal wing mounted forward of and above the rear wing was also removed after the FIA banned its use for the 2018 championship.

The MCL33 made its track début at the Circuito de Navarra in Spain where it completed a shakedown before moving to the Circuit de Barcelona-Catalunya for pre-season testing. Fernando Alonso reacted positively after the first day of testing, highlighting the Renault R.E.18 engine was an evolution of the established R.E.17 model; by comparison, the Honda engines that McLaren used between 2015 and 2017 had always been brand-new as Honda had not carried elements of the previous engine's design over to subsequent iterations. However, the team struggled with several technical problems—including electrical and hydraulic faults—that limited the car's running. McLaren were forced to defend their design when it was suggested that their reliability issues had been triggered by an inherent flaw in the chassis as the Scuderia Toro Rosso STR13, which used the Honda engines McLaren had abandoned, had run throughout pre-season testing without interruption. At the conclusion of testing, the MCL33 had failed to hit its mileage targets—just 2,788 km (1,732.4 mi) compared to the 4,481 km (2,784.4 mi) completed by Mercedes, who completed the most mileage across the eight days of testing—and McLaren admitted that they were underprepared for the season.
Early development
Prior to the car's launch, McLaren announced plans for an extensive aerodynamic update to be introduced for the opening round of the championship in Australia.
Competition history
In the week before the Australian Grand Prix, Alonso predicted that the race would be the most difficult of the championship for McLaren. Despite this, he and Vandoorne qualified in eleventh and twelfth place, which became tenth and eleventh following the application of penalties to other drivers.

Notes
- ^ McLaren signed a technical partnership with Petrobras that will see the company supply fuel and lubrucants to the team from 2019. As part of the agreement, Petrobras branding appears on the MCL33, but the car uses BP fuels and Castrol lubricants.
