That’s according to Avis, which has created the Avis Driving Ratio (ADR) to determine once and for all the leader of the list of great UK drives.

When applied to three UK roads which are often cited by motoring forums, car clubs and the media as the nation’s best due to their stunning locations and challenging drives, the Avis Driving Ratio (ADR) found the stretch of the A591 topped the list, followed by B315 in Somerset and A535 in Cheshire

“There are four key phases of a drive,” said eminent quantum physicist, Dr Mark Hadley, who led the research. “Bends, acceleration, cruising and braking. A great driving road strikes just the right balance between the phases so you get the exhilaration of speed and acceleration whilst corners test your driving capabilities and long stretches allow you to enjoy the scenery. In creating the Avis Driving Ratio (ADR) we have calculated the optimum balance between those components, to scientifically establish the world’s best driving roads.”

The research revealed the A591 from Kendal to Keswick most closely matches the ideal ADR of 10:1 (10 seconds on a straight to every 1 second spent on a bend) with a ratio of 14:3, ranking it top in the UK as the ultimate road for driving.

“The time spent on the straight allows for the optimum time to appreciate the surrounding scenery before moving into the next bend, whilst still giving the driver the thrill and excitement you get from a challenging drive,” continued Dr Hadley. 

The N-222 from Peso de Régua to Pinhão in Portugal was identified as offering the world’s best overall driving experience, as it cuts right through the heart of the Douro Valley, and offering spectacular views and which also most closely matches the ideal ADR of 10:1 (10 seconds on a straight to every 1 second spent on a bend) with a ratio of 11:1.

In second place overall was Big Sur in California with a ratio of 8.5:1. For drivers wanting more of a challenge, the Nihon Romantic Highway in Japan with a ratio of 2:1 is full of hairpin bends, whilst in Europe, Italy’s Amalfi Coast drive with a ratio of 1:1 will leave drivers holding their breath as they navigate sharp bends and take in the views when they can. The Overseas Highway in Florida offers a ratio of 1240:1, making it the perfect road for those looking for a low intensity yet beautiful driving experience.
