McLaren P1: What you need to know
Almost visually unchanged from the Paris concept, the P1 will boast a total of 903bhp: 727bhp comes from the 3.8-litre twin-turbo V8 found in the 12C (albeit with larger turbos and a special crankcase), and 176bhp from an electric motor. This will allow the P1 to reach 186mph from standstill in less than 17 seconds, on its way to an electronically limited 217mph top speed. The P1 can produce up to 600kg of downforce, which approaches that of a Le Mans car.
At an average speed of 30mph, the new McLaren will be able to travel around 12.5 miles under electric-only propulsion.
No more than 375 units of the P1 will be produced, each with a price tag of £866,000.
