After watching this video, we can’t but feel for the McLaren engineers trying to do their work testing or simply driving the P1 under normal conditions and having to deal with all the (justified) attention that comes along with the job.
On the other hand, we're also grateful for supercar-spotter and YouTube channel owner Shmee150 and his friend in a deliciously sounding Ferrari 458 Spider for tracking down and filming the pre-production P1, without making any inherently dangerous moves in the process (or at least none that we saw in this video).
"We were out for a drive today in a brand new Ferrari 458 Spider and stumbled into a McLaren P1, with the new 903hp engine and electric motors as announced this morning," Shmee150 told CarScoop in an email. "It looked like a perspective buyer was out for a test drive, but great to hear the sound of the car and some clips out on the roads in the UK."
Earlier today, McLaren spilled the beans on the P1's hybrid powertrain revealing that the car features a twin-turbocharged 3.8-liter V8 petrol engine and an electric motor delivering a combined system output of 903HP (916PS) and 900 Nm (664 lb-ft) of torque.
