Here's your latest look at McLaren's latest Ultimate Series. It gets a name, too. Or at least a codename.

It's just a glimpse. Of what appears to be a brake light hidden in a world of exquisite carbon fibre aerodynamic components. But it's not just any brake light, it's a McLaren brake light.

Put it together with the exhaust tips McLaren posted last month, and you have the rear of the latest in the McLaren Ultimate Series. Or a glimpse of the diffuser part of it, at least. The car is codenamed the P15, and it's the successor to the P1. It'll be the most focused roadgoing McLaren yet. It will sacrifice comfort for speed, in the pursuit of hypercar glory.

McLaren will be showing us the whole car, and hopefully giving us the rest of the details, on December 10th.
