The award is organised by Practical Caravan magazine, the Camping and Caravanning Club and What Car? magazine, and reveals the best towing performers in all classes.
Practical Caravan editor Nigel Donnelly said: 'The Volkswagen Passat Estate tows brilliantly. It’s a pleasure to drive and travel in, economical to run and easy to live with. It also provides unshakeable stability and responsive steering, which leaves drivers fresh, ready to unhitch and start enjoying their holiday.'
Volkswagen also scooped the Up to 1424kg category with its Golf 2.0 TDI Match 5dr for the second year in a row.
The Ford Mondeo Estate 2.0 TDCi won the 1575-1724kg category and the BMW 520d Touring SE the 1725-1899kg category. Last year’s overall winner, the Land Rover Discovery, proved it’s still a great towcar by picking up the 1900kg and above category.
Chevrolet’s seven-seat Orlando 2.0 VCDi MPV was named as the Budget MPV winner.
This year’s Green Award went to Vauxhall for the Astra Sports Tourer.
Jim Holder, editor of What Car? magazine, said: 'What Car? has long helped people to buy their next new car with confidence, and we’re proud to be part of tests that help people to choose their next towcar with the same confidence.'
