How the P1 pushed McLaren to new limits.
Introduction
The McLaren P1 is the hypercar that revolutionised the way car companies design and build hypercars.
McLaren’s unique history, especially the legacy of the McLaren F1, pushed the company to regain its lost glory, and the P1 was the only way to achieve it.
McLaren’s philosophy with the P1 is that, unlike its predecessor, the F1, which only focused on speed, the P1 should have the best of both worlds: the speed and the ability to be driven daily
To make that possible, McLaren created a team full of expertise from every department possible, all the way from Rob Melville, the exterior designer, to Dan Parry Williams the chief design engineer and many others just to make the P1 come Alive.
Part One: How everthyting started
After the extraordinary success of the legendary McLaren F1, the company took a break from making road cars for over a decade. The reason is that the F1 was a halo car and for over a decade no car came close to its incredible performance.
That all changed in the early 2000s when McLaren noticed that both Ferraris and Porsches were on the road and track at the same time, and that’s when McLaren felt it was being left behind.
In 2010, everything changed for McLaren because they finally decided to commit to making road production cars, and in 2011, we got the McLaren MP4-12C, the first modern McLaren car.
Even though the MP4-12C was a powerful car, it had a V8 and a strong Formula 1-inspired design philosophy. It wasn’t enough for McLaren. Entre P12 (P1 now), which was conceived even before the 12C hit the roads.
The P1 wasn’t just a 2nd F1, it was meant to represent the new era of McLaren. An era of speed, precision, and F1 Titles.
Finally, after a lot of planning and hard work, the McLaren P1 was unveiled at the 2013 Geneva International Motor Show and turned everyone’s head with its stunning design and the technology it carries. The debut was so successful that Autoweek described the initial impression as “positive, emotional and intense.” Ever since its debut until today, the P1 is still one of the fastest, beautiful and technologically advanced cars McLaren has ever given to the world.
Part Two: Name of the dream
The name McLaren P1 Means (Position One), and that just shows how determined McLaren was to show the world their ability to create a world-class car that can compete with the likes of Ferrari and Porsche.
That just shows that after two decades, the McLaren F1’s soul is still alive, even with the hybrid technology.
From secret sketches to shocking unveilings, the Lamborghini Reventon wasn't supposed to be here.

The Reventon was a styling exercise inspired by modern fighter jets. It was intended to test extreme design language. It wasn't easy to get approval from the management, but it did. pic.twitter.com/PJXbylJfNx
Part Three: A Hybrid Goes Vroom.
The P1’s massive power comes from an aluminium alloy 3.8L V8 that was first used on the MP4-12C, but of course, the P1 uses a much more advanced and powerful version of it.
The new engine is combined with an electric motor that was developed with a Formula E partner, which resulted in a combination of 903 hp and 664 lb-ft (727 hp and 531 lb-ft, from ICE) and (176 hp and 192 lb-ft torque from E-motor)
Other than the massive engine and powerful engine, the P1 has a couple of new tricks under its carbon fibre body
To make the P1 go fast, McLaren used a power system they adopted from Formula 1, which is called IPAS(Instant Power Assist System).
What’s IPAS, you may ask? Well, in simple terms, the IPAS system is like a turbocharged adrenaline shot delivered instantly when you press the accelerator—no waiting, no lag.
The IPAS is made of an electric motor that generates 177 hp and is integrated into the transmission.
It works automatically when you floor the car and regenerates power when braking. Other than the instant boost, the IPAS system eliminates turbo lag to make sure you’re not half a second slower than your competitor. It’s very similar to the KERS system in Formula 1 and is also used by the Ferrari LaFerrari.
Other than the IPAS system the P1 has adopted another Formula 1 technology, which is the DRS (Drag Reduction System).
In Formula 1, the DRS was created to allow cars to overtake others by temporarily reducing aerodynamic drag, which in turn helps the car go faster in a straight line.
McLaren used this technology on their P1 to make it go faster on both track and road, making it one few cars in the automobile world to use this technology in road production cars.
Combining the DRS with the IPAS has made the P1 an uncontrollable beast on the track, and if you’re having a bad day, it may be worse on the street.
Shifting Gears
The P1 has a robust Graziano 7-speed transmission that’s capable of changing gears in just 100 milliseconds. This transmission is made of Cast aluminium alloy, which is great for handling the immense power that’s coming from the engine.
A hybrid song
The P1 has a lightweight Titanium exhaust that sounds more like a racing car on the road rather than a Prius. Would you please not believe me? Take a listen
Crunching the Numbers
Even though the P1 couldn’t save Jeremy Clarkson’s house in The Grand Tour, it still did an incredible job on the race track. The V8 and IPAS can accelerate the P1 from 0-60 in 2.8 seconds, which remains unbelievable to this day, and reach a top speed of 217 MPH. Even though these stats may be “normal”, especially with the emerging full electric hypercars like the Rimac C Two, which can do 0-60 in 1.85 seconds. Still, what made the P1 special is that it was the first hybrid car to go from 0-124MPH in under 7 seconds, plus it can reach 186MPH faster than most sports cars.
Part four: It Looks fast even when not moving
The P1 weighs just 1,395 kgs, which is pretty light for a car that has a V8 and an e-motor, but still a bit heavier than a one:1, but it weighs less than a Koenigsegg Regera.
Nonetheless, McLaren did an incredible job of reducing as much weight as possible, especially with a car that has two massive engines.
The monocage of the P1 is made of CFRP (Pre-preg carbon fibre reinforced polymer), which is used in both the fighter jets, as the incredible F-22 Raptor and the original DNA of the P1, which is Formula 1. All in all, the CFRP only weighs 90kg.
The P1 panels and Aerodynamic Surfaces are made of Autoclaved carbon fibre composites. For those who don’t know what an autoclaved carbon fibre is? Well, an Autoclave is a high-temperature, high-pressure oven that is used to harden carbon composites. This results in very light yet strong carbon compsite that’s mostly used in Formula 1 and Fighter jets.
What’s wrong with that wing?
To support the two massive engines and make the P1 an F1 contender for the road, McLaren needed to create some crazy aerodynamics, and it did.
Let’s start with the craziest part, and that’s the Wing
The wing on the P1 isn’t some wing that automatically adjusts to the speed but its a bit more complicated than that.
The P1 wing has three major roles and thay are as follows:
Generate downforce, at high speeds, 160MPH+, the wing can generate as much as 600kg of downforce.
Those who don’t know what downforce does, downforce is when a car is pushed on the road by air.
This improves the car’s stability at high speeds, during cornering, and braking. The downforce will give the driver the confidence to push the car to its limits during racing.
Furthermore, the wing can also assist in braking. During hard braking, the wing tilts steeply forward to create resistance against the air.
Lastly, the Wing is a major part of the DRS, and that’s because the wing adjusts itself automatically once the DRS button is pressed. After that, the wing flattens, which in return cuts drag by around 23%, which would allow the P1 to accelerate faster in a straight line and reach the top speed much quicker.
Other than the incredible wing, the P1 still has a couple more tricks under its carbon body.
Under the P1’s nose, there are active front laps that extend or retract to balance the car with the rear wing.
Lastly, the entire body of the P1 is sculpted to get in as much air as possible. One of these is the air intake snorkel that’s located at the carbon fibre roof. This snorkel directly feeds the 3.8L twin-turbo V8 clean, high-pressure, cool air that reduces turbo lag and maximises engine performance, especially at high speeds.
The P1 has no carpets!
Inside the P1’s cockpit, we can see that McLaren went with the minimalist and driver-focused style. Most of the interior is made of carbon fibre and other lightweight materials like Alcantara. The steering is made of carbon fibre and Alcantara, with two prominent buttons on it. These Matrix-influenced buttons are the DRS (Blue) and IPAS (Red).
McLaren’s simplicity didn’t stop at the steering wheel; rather, for the sake of saving weight, McLaren had an option of removing the seat’s carpets, which would save around 15-20 kg to go 1 second faster.
Speaking of seats, the P1 has carbon bucket seats that are barely comfortable, but nobody thinks of comfort while driving a hypercar.
Other than that, the P1 has your typical stuff, like an AC, touch screen display and a gear selector, but what you don’t get is no physical cup holders, glove box, or storage bins, no wood trim, no chrome, no bulky switches. And most importantly, you get a drive mode selector which changes this car from an eco-friendly car to a track beast you don’t wish to go against.
What did the P1 achieve?
Lightweight, superfast, very expensive and extremely rare, where did all of this lead the P1 to?
The P1 has multiple race track records, most prominently are the:
Top Gear track (Dunsfold): 1:13.7, faster than the LaFerrari but tied with the 918
EVO Magazine (Anglesey Coastal): 1:12.8
Goodwood Hillclimb: 47.07 sec (very fast)
If you are wondering about a Nürburgring record, then I can’t give you one because McLaren refused to release a time, but they said it’s sub 7 minutes, and I kinda believe them.
Other than the Lap records, the P1 also got a couple of awards, most prominently are:
Car of the Year by Top Gear in 2013, car of the year by EVO Magazine in 2014, and Best Hybrid Performance Car in 2015 by Car Magazine (UK).
Holy Trinity showdown
(Even I will make separate posts about the 918 and the LaFerrari, this comparison is just based on numbers and not innovation.)
The P1 Spirit still lives on
Before the P1, McLaren lacked global recognition as a supercar company for the road like Lamborghini, Porsche or Ferrari, but that all changed after the P1.
After the P1, McLaren got a new beginning, and it was looking great. McLaren became known for proving it could build a technological masterpiece equal to or better than anything from Italy or Germany. It showed that McLaren can get their hypercars onto our everyday roads and destroy nearly every car on the road.
And that’s not all, the P1 also influenced the newer McLaren hypercars like the Senna, which many consider a more brutal version of the P1, and that’s not mentioning other P1 variations like the P1 GTR (not road-legal) and the road-legal P1 GTR by Lanzante Motorsport.
Furthermore, the P1 innovations were later used on the new McLaren models like MonoCage carbon tub, which evolved into the MonoCage carbon tub || and was used on the 720S, the hybrid-electric integration, which was the basis for Artura’s V6 hybrid system and Active aerodynamics, which inspired the designs in the 675LT, 720S, Senna, and Speedtail.
Price and Rarity
The P1’s MSRP was $1.15M but with only 375 units roaming our planet prices have now changed a bit, with the cleanest P1 now goes for around $2M plus and a less kept P1 can go for around $1M-$1.3M. These prices change based on milage and MSO specs.
A final goodbye
All in all, the McLaren P1 is the result of a company that dreamed of making cars that conquer the roads among everyday drivers and conquer race tracks among the world’s best cars and drivers. It was a dream that flourished, maybe more than the expectation of McLaren itself and now in 2025, McLaren will reignite that racing legacy by winning the F1 championship after 17 years of losing.
