A week ago, our spies spotted what appears to be a test mule for McLaren's P1 successor. Sighted at the Nurburgring, it looks like the Woking-based manufacturer was using a 675 LT that was fitted with several exterior add-ons including a rear wing and larger air intakes at the front. It even bears the internal code for McLaren's supposed P1 successor, MV715-23 or BP-23 for short.

Now, McLaren has officially released new photos of the P1 successor draped in heavy camo. Called the BP-23 prototype, the upcoming hypercar is currently being tested on a 720S mule and is set to become the 'fastest ever McLaren'.

Based on the photos provided, the BP-23 has been converted to a single-seater, with the driver's seat placed at the center of the cockpit. This is reminiscent of the McLaren F1 which had a three-seat layout and the driver was placed at the center. With the heavy camouflage, it's hard to tell what McLaren changed on the 720S test mule but we do get to see cameras placed on the side mirrors. This could mean that the P1 successor will have digital displays for the side mirrors.

Inside, it has a minimalist design which follows with the same layout of the original 720S and F1 supercar. An array of switches dominate the dashboard and is joined by the unique folding digital instrument panel.

Its powertrain still remains a mystery but as it is set to succeed the P1, it will likely have a hybrid powertrain that is capable of producing more than 900 PS. In review, the P1 is powered by a 3.8-liter twin-turbo V8 that is helped along by an electric motor. It generates 916 PS and can sprint from 0 – 100 km/h in 2.8 seconds. Top speed is electronically limited to 350 km/h.

Apparently, only 106 examples of the BP23 will be made and all have been spoken for already. When launched, the BP23 Prototype will bear its official name, Hyper GT. As to why only 106 cars will be built, that's because McLaren sold 106 examples of the original F1.
