|Never before has Formula One technology been so integrated into the design and performance of a road car. The McLaren P1 touts a kinetic energy recovery system (KERS) and Drag Reduction System (DRS), both enabled by buttons on the steering wheel. Practical application of KERS gives the P1 176 additional horsepower that can be tapped to boost speed, increase overall output, or solely power the car up to 12 miles before needing to charge. This isn’t a car anyone is going to hyper-mile for a little savings at the pump, but it is a hybrid nonetheless. Coupled with 3.8-litre, twin-turbocharged, V8, horsepower numbers exceed 900 with torque above 660 lb. ft. A seven-speed, dual-clutch transmission carries the P1 up to a stratospheric top speed of 217 mph. To bring the P1 back down to Earth, carbon-fiber braking by Akebono is precise. When given a chance to drive the P1, Formula One driver Sergio Perez said, “When I first touch the brake it really feels like stopping a Formula One.” So, your McLaren P1 should feel right at home taking on any cars that dare attempt to challenge it.|

Succeeding the F1 that was introduced in 1993, the P1, whose name stands for "Position 1" (which means "first place"), is the second model in McLaren's "Ultimate Series" model range and the first one since McLaren Automotive's founding in 2010. Designed to "be the best driver's car in the world", the P1 utilizes technologies from Formula One, including a hybrid powertrain.
The McLaren P1 uses a specialized version of the McLaren MP4-12C's 3.8 L (3,799 cc) twin-turbocharged V8 engine, with the new codename as M838TQ and the power output at 727 hp (542 kW) and torque output at 531 ft·lb (720 N·m). A new technology in supercars, however, is the addition of an electric motor for additional performance. In this case, the P1's V8 engine is paired with an in-house-developed electric motor that produces 176 hp (131 kW) and 192 ft·lb (260 N·m) of torque, giving out a total power output of 903 hp (673 kW) and a torque output of 723 ft·lb (980 N·m), although McLaren instead claims 664 ft·lb (900 N·m) in order to protect the gearbox; this torque figure is also used in the Forza installments. When the electric motor runs out of battery, the V8 engine activates and the battery self-recharges.
The car has a dry weight of 3075 lb (1395 kg) and a curb weight of 3411 lb (1547 kg). The resulting power-to-weight ratio is a minimum of 584 hp (435 kW) per tonne (3.41 lb/1.54 kg per hp) and a maximum of 647 hp (482 kW) per tonne (3.78 lb/1.54 kg per hp). Sending power to the rear wheels is a seven-speed McLaren SSG dual-clutch automatic gearbox like the one used in the 12C, but upgraded.
The McLaren P1 uses a seven-speed dual-clutch automatic transmission just like the one in the 12C, but improved. The car can do 0 - 60 mph (97 km/h) in 2.8 seconds, 0 - 100 mph (161 km/h) in 5.2 seconds, 0 - 124 mph (200 km/h) in 6.8 seconds, and 0-186 mph (300 km/h) in 16.5 seconds, a "full 15 seconds faster than the McLaren F1", as well as 0 - 200 mph (322 km/h) in 23.3 seconds. McLaren claims that the P1's top speed is electronically restricted to 217 mph (350 km/h). However, with the electronic limiter removed, the P1 has a top speed in excess of 245 mph (394 km/h), which not only correctly makes the P1 faster than the F1 in every performance aspect, but is also always reached or exceeded in the Forza games. At 160 mph (257 km/h), the P1 generates 1323 lb (600 kg) of downforce.
Limited Collector Edition
The McLaren P1 Limited Collector Edition is a special tuned variant of the P1 in Forza Motorsport 5. It is exclusive to the Limited Edition release of Forza Motorsport 5, with a special livery and performance upgraded to the top of Class R.
The McLaren P1 appears with a Team Forza variant in the Ten Year Anniversary Car Pack add-ons for Forza Horizon 2 and Forza Motorsport 6. In the former game, the Team Forza P1 is basically a reskinned P1 with a Ten Year Anniversary livery. In the latter game, the Team Forza P1 remains the same as in Forza Horizon 2, but with performance upgraded close to the top of Class R.

The McLaren P1 is currently the best-performing road-legal McLaren in the series, with a high-powered twin-turbo hybrid V8 powerplant paired with other Formula One technologies for maximum performance. Off the line, the P1 has tremendous acceleration, capable of reaching 100 mph (161 km/h) in 5.2 seconds, as well as being able to reach 200 mph (322 km/h) faster than most cars, making it one of the fastest-accelerating RWD cars in the series. This is partly due to the use of tight gear ratios. The P1's trick suspension and 1323 lb (600 kg) of downforce at 160 mph (257 km/h) enable fast cornering; in conjunction with the Drag Reduction System (DRS) that operates the rear wing and folds it up under heavy braking to decrease braking distances, the P1 gains a handy performance advantage over many cars. Outperforming its predecessor in all performance aspects, the P1 also has a very high top speed exceeding 246 mph (396 km/h), later increased to 255 mph (410 km/h) in Forza Horizon 3. Its closest competition includes the Ferrari LaFerrari, Porsche 918 Spyder, and Pagani Huayra BC.
In Forza Horizon 3, due to the P1's tight gearing, the car can benefit greatly from a top speed-oriented setup, which exploits wider gearing and subsequently yields a maximum top speed of 272 mph (438 km/h), which can then be increased even further to 295 mph (474 km/h) with the right gearing and the use of the Loop-the-Loop stunt track pieces in the Hot Wheels Expansion. In the same game, the car's braking performance was increased to outmatch that of the LaFerrari, which is also slower to 186 mph (300 km/h) by one full second (the P1 does that in 13 seconds).
- There are multiple achievements related to the P1 in the Forza series:
- Silver and Gold (Forza Motorsport 5) - Earn gold at Silverstone Grand Prix Circuit in the P1 and Aston Martin One-77
- P1 vs. the Nordschleife (Forza Motorsport 5) - Finish the P1 vs. the Nordschleife Rivals event having set a lap time of 07:15.000 or better
- Just don't scratch it (Forza Horizon 2 Presents Fast & Furious) - Obtain the P1
- Pre-release screenshots and videos of Forza Motorsport 5 depict a P1 with different hood vents (pictured in Gallery below).
- In Forza Horizon 3, the P1's front bumper, carbon fiber exterior door inserts on the sides, rear engine cover, and rear bumper cannot be painted with any decals at all.
- The P1's mirrors are permanently carbon fiber black and cannot be recolored, despite some real life examples of the car having differently colored mirrors.
- The McLaren P1's active rear wing works differently in the games than in real life. It always stays up, even when the car is standing still. The wing also tilts to a 0° angle at 140 mph (225 km/h) and stays permanently up, even at speeds of over 230 mph (370 km/h).
- The P1 comes with only Volcano Orange and Volcano Yellow as manufacturer colors, despite the large amount of colors the car can use in real life.
- The McLaren P1's electric motor was later used in the Formula E SRT_01E electric formula race car.
- The Horizon renditions of the P1 use a front weight distribution stat of 41%.
