Professional Driver magazine editor Mark Bursa said of the rationale behind the ranking: ‘The Audi A8 L edges it on low running costs, excellent manufacturer support thanks to the Audi Chauffeur Programme, and, perhaps crucially, its four-wheel drive ability. This gives the A8 L an edge over its rear-wheel drive competitors, and that could make all the difference in the winter snow.’

As part of the testing process, the A8 L 3.0 TDI quattro SE was reviewed on a circular route taking in a variety of typical road types. Vital chauffeur requirements such as high-end infotainment systems and boot space were considered, and a point-scoring system was used to rate various features of the car, before an overall average score was calculated. Further marks were factored in for the financial aspects of owning and operating each car tested, including purchase price, whole life costs and monthly contract hire prices provided through manufacturer chauffeur or fleet programmes.

This autumn also saw the new-generation Audi A8 (pictured) make its world public debut at September’s Frankfurt Motor Show. Now available to order priced from £58,800 OTR, the latest A8 offers a revised body structure as well as an engine line-up that offers more power along with better fuel efficiency and EU6 compliancy. The new model is set to start first UK deliveries start in January 2014.

Businesses and professional drivers can also benefit from the Audi Chauffeur Programme, which offers finance, service and maintenance packages designed with professional users in mind. Available for a range of high-end Audi models, including the A6, A7 Sportback, Q7 and A8 L, the programme includes comprehensive servicing and maintenance for the duration of the agreement, as well as an enhanced unlimited mileage Audi warranty for three years, extending to a five-year limited warranty upon request.
