It’s narrow with multiple curves. In fact, it has hardly any straight bits at its southern end, so it’s more like the Millbrook Alpine handling track, used all year to put test cars through their paces.
Both have an incredible variety of curves, cambers and elevation changes and if treated with respect, they will reward any keen driver. Just remember, on the South Downs you won’t have much time to admire the scenery you’ll be so engaged.
It was on the Devil’s Dyke Road that I once took an Aston Martin DB7 for a quiet, relaxing drive in the countryside. A beautiful car, in a beautiful part of the world. Both fully lived up to expectations.
