The three-seater hypercar ("it's more of a GT", says McLaren, with wonderful British understatement), with its hybrid powertrain, is being built by McLaren Special operations (MSO), and all 106 examples (a nod to its spiritual predecessor, the McLaren F1, which was built in the same number), are already sold.
GRR attended a McLaren dinner last month, when the BP23 was discussed in more detail. There will, apparently, be no spiders and no track cars. The BP23 is definitively "not a replacement for the F1 but an homage to the F1". The number of applications to own a BP23 has outnumbered the number of cars being built by three to one.
MSO is currently starting the specification process on each car with prospective owners, with a view to introducing the hypercar, which will be an addition to the Ultimate Series model range, to the market in 2019.
The cost of each hypercar is £1.65m plus tax. Given that demand has outstripped supply by a factor of three, that price already looks like a bargain.
