McLaren has yet to launch the long-awaited three-seat Speedtail, yet it’s just been revealed that its MSO division is working on its next project that, according to reports, will be even more extreme and limited than the Speedtail.

A pair of prolific car collectors in the U.S., dan_am_i and x_marc_the_spot on Instagram, recently published images teasing the project. Dubbed BC-03, the car will allegedly be limited to just 5 units worldwide and will not be a three-seater like the Speedtail.

Understandably, the two future owners of the vehicle are remaining tight-lipped about it, but reports claim the BC-03 will be a production version of the Vision GT concept McLaren designed for Gran Turismo last year.

If true, this means the BC-03 will be a single seater focused on track performance. It could, therefore, make use of similar aerodynamic elements as the concept, including a towering rear wing, huge air intakes, and ultra-lightweight body panels. Think of it as the McLaren equivalent of the Lamborghini Veneno, albeit with much more performance and advanced technologies.

The Vision GT concept used McLaren’s 4.0-liter twin-turbo V8 mated to a pair of electric motors driving the front wheels for a total of 1150 hp and 1275 Nm of torque. If these figures are replicated on the BC-03, it will be comfortably the fastest vehicle the British automaker has ever produced.

Buyers of the car have apparently been previewed the vehicle by way of a single 2D sketch. Right now, it remains unknown when McLaren will unveil the BC-03 hypercar.
