Two McLaren employees were killed when the sports car they were travelling in crashed near to the Formula 1 giant's technology centre.
The staff members, who were in a blue Subaru Impreza, were pronounced dead at the scene following a collision with a Ford Transit van on the A320 in Ottershaw, Surrey, at 12.10pm today.
A man in his 60s who was driving the van was taken to St George's Hospital in Tooting with serious injuries, Surrey Police said.
McLaren confirmed that the two staff worked for McLaren Automotive which produces road cars and is based at the same site as the McLaren Formula 1 team.
A Surrey Police spokesman said: "Officers are appealing for witnesses. Anyone who may have seen the incident, or the events surrounding it, is urged to contact Surrey Police as a matter of urgency."
