Chris Barrie presents National Geographic?s latest series celebrating British machinery through the ages.

In March filming took place near Epping for the Deloreans? inclusion in the series. It was a cold and windy day but for the participants the day turned out to be much cooler than that.

Two Deloreans took part in the filming. The Timecar and a beautiful automatic Delorean with black interior.

I truly believe that no vehicle in the forthcoming series is going to eclipse the Delorean. But then I am, just slightly, biased.
