F1 world champ Surtees surfaces in France
The 1964 Formula 1 winner, who is still the only person to have claimed world records on both 2 and 4 wheels, drove an electric powered Ginetta G50 EV through the 31-mile tunnel.
He didn't break any speed records this time though as he had to stick to the 50km/h speed limit.
What didn't help with keeping a good time was also his constant stopping to have a closer look at the tunnel, which he called "a tremendous engineering feat".
"You certainly wouldn't want to be subject to any claustrophobic feelings down there.The tunnel is very small in parts," added the 75-year-old after eventually resurfacing in Coquelles, France.
