A new McLaren hypercar may be just around the corner, and not just any old hypercar, but the successor to the P1.

McLaren on Wednesday released a video to social media listing the attributes of its cars whose names end with the number “1,” i.e. the F1 and P1. The video concludes with the date Oct. 6 on display, suggesting that this is when the P1 successor will be revealed.

The timeline corroborates a report from March, which claimed the P1 successor would be revealed by the end of the year, based on information provided by dealer sources.

An earlier report claimed the car would arrive in 2026, though this may be when production starts.

The new car, code-named P18, will be the next installment in McLaren’s Ultimate Series, whose last addition was the Speedtail grand tourer.

The P18 is expected to feature a plug-in hybrid powertrain using a newly developed twin-turbocharged V-8 as its gas component. While the configuration is the same as what McLaren used in the P1 launched more than a decade ago, the new car is expected to benefit from a much lighter hybrid system. Peak output should also be higher than the 1,055 hp of the Speedtail, which was also a V-8 plug-in hybrid. That should result in a significant boost in performance compared to the P1, which had 903 hp.

Other features are tipped to include a newly developed carbon-fiber tub, gullwing doors (instead of McLaren’s typical butterfly doors), and Formula 1-inspired styling. Production is expected to be limited to less than 400 units.
