What you're looking at is not some high tech medical laboratory. It is in fact, McLaren Automotive's assembly line for its P1 supercar located in Woking, United Kingdom.

The carmaker posted photos of it on their Facebook page. The 903hp supercar is built on a dedicated line at the McLaren Production Centre, where the 12C and 12C Spider are also manufactured.

McLaren will only build 375 units of the hybrid supercar, which will make the P1 more exclusive than its main competitors, the Ferrari LaFerrari (499 units) and the Porsche 918 Spyder (918 units).

McLaren has confirmed that most of the production run is already sold, with no cars left available for the United States, Asia and Middle East. Few cars remain for European clientele.

The McLaren P1 features a hybrid powertrain combining a 3.8-liter twin-turbocharged V8 engine developing 727 hp and an electric motor producing 176 hp. Combined power output is 903 hp (917PS) and 900 Nm (664 lb-ft) of torque, catapulting the P1 from standstill to 100 km/h (62 mph) in under 3 seconds and allowing it to reach a top speed of 350 km/h (217 mph).
