Customer Review, October 12, 2018," and was rumored to refer to a production version of the Gran Turismo concept. It's said that MSO showed those in attendance a sketch of what's to come.
The Supercar Blog broke the story, and McLaren MSO just confirmed to UK car blog Pistonheads that the " BC-03 is a bespoke customer commission being created by McLaren Special Operations." It wouldn't divulge anything more "because the specifics of the project are confidential between MSO and its client." We have only circumstantial evidence and hearsay at the moment, but two days after dan_am_i posted the slide, he returned to Instagram to post a side shot of the McLaren Ultimate VGT concept with #BC03 as one of the hashtags.
The McLaren Life forum chimed in, saying MSO is making just five examples, and three have already been claimed. One goes to the aforementioned dan_i_am, the others to fellow seven-figure-car buyers x_marc_the_spot and mannykhoshbin. The BC-03, according to the forum post, is "inspired by" the Playstation concept and will "use new cutting-edge technologies, and a special type of carbon fiber."
How much inspiration will make it to reality, that's the question. The Vision GT car was a track-only single-seater with 1,134 horsepower and 940 pound-feet of torque. Those numbers came from a combination of the brand's 4.0-liter twin-turbo V8 powering the rear wheels, and two high-output electric motors powering the fronts. It weighed 2,204 virtual pounds. If the real thing comes close to those numbers, the BC-03 would be lighter than the Senna, with just as much if not more power than the Speedtail. We have yet to see if it will be a track-only car, but that wouldn't surprise us if so. We're confident that one aspect that won't make production is the prone, "motorcycle-like" driving position.
The rumored price: $3 million, which — considering what's happening in the segment — isn't bad. The BC-03 probably won't possess the same monumental old-time Formula 1 engine note as the Aston Martin Valkyrie AMR Pro, but it should provide some good competition should any of the five owners care to risk the BC-03 on the curbs. And if Le Mans really does create a hypercar LMP1 class ...
