I have just seen this tweet from @paulvalet7 showing a brand new McLaren Speedtail after it had been in a fire. This seems to be a recurring theme with McLaren's at the moment. First the 600LT, then Senna, now the brand new Speedtail.
This incident occurred on a test car on the A3. Luckily the Surrey Fire and Rescue department made it before it got too serious.
