The McLaren Senna is a limited-production mid-engine sports car manufactured by McLaren Automotive. The car is the newest addition in the McLaren Ultimate Series, joining the F1 and the P1; however, it is not a direct successor to both of the cars. The Senna was unveiled online by the company on December 10, 2017, with the official unveiling taking place at the 2018 Geneva Motor Show.
The car is named after the Brazilian Formula One race car driver Ayrton Senna, honouring and giving tribute to his success with the McLaren Formula One Team between 1988 and 1993 Formula 1 seasons. Senna won three Formula One World Driver's Championship titles and thirty-five Formula One Grand Prix with the team; McLaren also won four consecutive Formula One World Constructor's Championship titles with Senna as part of their driver line-up.
McLaren Automotive holds the rights to the Senna family name along with the Instituto Ayrton Senna. The organization and McLaren have made the Senna name exclusive to the car, thereby prohibiting any other company from using the name.
McLaren's main focus while designing the Senna was to achieve faster lap times. In order to do so, McLaren developed a lightweight design that incorporated aerodynamic elements.
The Senna is largely based on the McLaren 720S, using a modified version of its carbon fibre monocoque and engine. The Senna is powered by a modified version of the 720S' 3,994 cc (4.0 L; 243.7 cu in) twin-turbocharged V8 engine codenamed the M840TR. It utilises a seven-speed dual-clutch transmission that delivers all 800 PS (789 bhp; 588 kW) at 7,250 rpm and 590 lb⋅ft (800 N⋅m) of torque at 5,500 rpm to the rear wheels. Unlike the previous offering in the Ultimate Series, the P1, the Senna does not use an electric motor in favour of its low dry weight of 1,198 kg (2,641 lb), which allows for a power-to-weight ratio of 658 hp (491 kW; 667 PS) per ton.
Carbon fibre aerodynamic pieces constitute the car, with a large adjustable double-element rear wing (that is operated electronically and has various settings in order to provide optimum performance while also acting as an airbrake), double-element diffuser, Formula One-inspired roof scoop, front and side air intakes, rear air louvres, and large front fenders. Inside the panel beside the intakes is a small set of mini-canards. Areas of low pressure are accompanied using high-performance radiators that ensure improved engine cooling. The car uses dihedral doors, like the previous offerings in the Ultimate Series, and also has optional windows applied on the lower area of its doors.
The Senna uses a new generation of Brembo's carbon ceramic brakes, containing a compound that has three and a half times better thermal conductivity than before, making the brakes smaller and lighter. It also features a new set of lightweight center-lock alloy wheels designed for Pirelli P-Zero Trofeo R tyres. Its central design is a new generation of McLaren's carbon fibre monocoque named MonoCage III, which contributes to the car's relatively low dry weight. The car utilises a top mounted inconel-titanium exhaust system with three outlet pipes in order for a better engine sound track and engine emissions. The interior consists largely of exposed carbon fibre and Alcantara, with seats that can be upholstered in Alcantara or leather, depending on the customer's preference. Behind the two seats is room large enough for two helmets and race suits, reflecting the car's minimalist and track focused design. The car utilises McLaren's hydraulic RaceActive Chassis Control II (RCC II) suspension along with double-wishbone control arms.
Manufacturer claimed figures: In February 2018, McLaren released the full performance statistics of the track-oriented Senna model:
- 0–100 km/h (0–62 mph): 2.8 seconds. 
- 0–200 km/h (0–124 mph): 6.8 seconds.
- 0–300 km/h (0–186 mph): 17.5 seconds.
- Standing 1⁄4 mile (402 m): 9.9 seconds.
- Power-to-weight ratio: 659 hp/tonne.
- Top speed: 211 mph (340 km/h) (redline limited).
Independent test (done by Autocar):
- 0–97 km/h (0–60 mph) in 3.1 seconds
- 0–161 km/h (0–100 mph) in 5.5 seconds
- 0–193 km/h (0–120 mph) in 7.1 seconds
- 0–290 km/h (0–180 mph) in 19.8 seconds
- Standing 1/4 mile in 10.4 seconds.
Every car will be hand-built at the McLaren Production Centre in Woking, Surrey, England with a production run of just 500 units, all of which are already sold. The McLaren Senna is listed at the price of £750,000 (US$837,000) with the final car auctioned at a price of £1,916,793 (US$2,670,000). Deliveries are scheduled to begin in the third quarter of 2018.
McLaren Senna GTR
At the 2018 Geneva Motor Show, McLaren unveiled the track-only iteration of the Senna dubbed the Senna GTR. The GTR utilises a dual-clutch race transmission for faster gear shifts, a revised suspension system and Pirelli racing slicks in order to make it the fastest non-Formula One vehicle McLaren has ever created for faster lap times. The Senna GTR is estimated to produce at least 825 PS (607 kW; 814 hp) from its 4.0 L twin-turbocharged V8 engine and is meant to be faster and more agile than its road-going counterpart. On the exterior, the GTR utilises wider front and rear fenders, a larger front splitter, new wheels and a bigger rear diffuser in order to make the car generate about 2,204 lb (1,000 kg) of downforce. The Senna GTR will be limited to only 75 examples and will have a cost of £1 million each.
In reviewing the future regulations for the World Endurance Championship, the Fédération Internationale de l'Automobile (FIA) identified the Senna GTR as one of several models that fit their vision of a replacement for the Le Mans Prototype class.
