The McLaren P1 GTR-18 is an aftermarket conversion of the McLaren P1 supercar performed by Lanzante. The package is essentially an exterior upgrade that enhances aerodynamics, but the cars are also finished in historic racing liveries. Now specialized in servicing and restoration of classic cars, Lanzante used to run its own motorsport team, including the one that won the 1995 24 Hours of Le Mans with a McLaren F1 GTR under Kokusai Kaihatsu sponsorship. In 2016, Lanzante converted six P1 GTR models to road-legal specs and called them the P1 LM. The P1 GTR-18 is thus Lanzante's second project based on the P1.

What sets the McLaren P1 GTR-18 apart from the standard P1 GTR?

At first glance, you can notice that the front fascia boasts a notably larger splitter. The plate extends more than usual onto the sides, but it also extends farther away from the body in the center too, which likely improves aerodynamics. There's also a new scoop on the roof, which improves cooling to the engine, but it also directs air over the car to enhance aerodynamics.

But arguably the biggest improvement is the longer body. This is visible only if you look at the car's profile, which reveals a longer rear overhang and a longer rear deck. It's only a few inches, but this upgrade also improves aerodynamics. The rear wing was also altered, now sitting a bit higher. It's also a tad wider, so it generates more downforce that the P1 GTR's standard wing.

The looks are rounded off by a special tint for the exposed carbon-fiber elements, as well as the unique livery. This specific model is finished in the Gulf Team Davidoff livery of the last F1 GTR produced by Lanzante for racing. It combines the iconic light blue and bright orange of the Gulf livery with black and dark red on the sides. Lanzante took the codes and samples from the original F1, so the hues are the real deal.

Lanzante will make five more cars and each will sport an F1 GTR-based livery. There's no word as to what liveries we will see on the other cars, but definitely expect one based on the F1 GTR that won Le Mans in 1995. That car isn't as flashy in black and dark grey, but I'm sure McLaren will find a way to spice things up.

What other goodies are available with the McLaren P1 GTR-18?

Lanzante is offering a few extras with the car, starting with a headset finished in the same paint scheme as the car. Why would you need a headset in the P1 GTR-18? Well, this car was designed for track use, so you can use it to talk to your passenger while doing laps on the Nurburgring. It will come in handy if you have a racing engineer in the pits as well.

How powerful is the McLaren P1 GTR-18?

Well, Lanzante didn't say whether it meddled with the GTR's drivetrain or not for this conversion, but the lack of info usually means that the drivetrain remains stock.

The drivetrain delivers a total output of 986 horsepower and 774 pound-feet of torque. That's an extra 83 horses and 51 pound-feet compared to the standard P1. The P1 GTR-18's output is also identical to the P1 LM, also based on the P1 GTR.

How fast is the McLaren P1 GTR-18?

Again, there are no official figures yet, but it's safe to assume that performance is very similar to the standard P1 GTR. So this race car should be able to hit 60 mph from a standing start in 2.8 seconds and reach a top speed of around 217 mph. That's also identical to the regular P1, but it's three mph higher than Lanzante's previous conversion, the P1 LM, limited to 214 mph.

How many McLaren P1 GTR-18s are being built?

Lanzante is planning to make six conversions with this package. But it's yet unclear if Lanzante is converting existing P1 GTR cars or if McLaren is building an additional six examples for them. For the P1 LM project, McLaren actually supplies six extra P1 GTRs, but production of the P1 ended four years ago, so McLaren might not have what it takes to build extra cars now. Either way, the P1 GTR-18 will be, alongside the P1 LM, one of the rarest iterations of the supercar.

How much does the McLaren P1 GTR-18 cost?

Pricing information is not yet available, but expect this highly limited model to cost significantly more than the P1 GTR. The latter retailed for around £2 million ($2.5 million as of April 2020) back in the day, so the P1 GTR-18 will likely fetch almost £3 million (about $3.7 million).
