CREWE, England — Now in its 11th year, the Bentley Arnage is coming to the end of its production run. To mark its passing, the company, a subsidiary of the Volkswagen Group, is building a limited edition of 150 cars that will be badged as the Arnage Final Series.Bentley says the Final Series will combine the refinement of the Arnage R with the performance of the Arnage T as 'the ultimate expression of class-leading luxury and effortless power' while signaling 'the end of an era.'The Arnage made its debut in 1998 as one of the last products engineered under its previous owner, Rolls-Royce. Under new parent Volkswagen, Bentley has launched several new-generation models, including the Continental GT, and Continental Flying Spur.The Arnage Final Series gets the 500-horsepower 6.75-liter V8 from the Arnage T, mated to a six-speed ZF gearbox with a locking torque converter. Standard features include an electronic stability program, 20-inch five-spoke alloy wheels, twin tailpipes and a retractable Flying B hood ornament.Inside, the car is fitted with a rear cocktail cabinet with stainless steel flask and shot glasses, two picnic tables finished in unbleached veneers, four Bentley umbrellas and a 1,100-watt Naim audio system.What this means to you: The last legacy from the old Rolls-Royce days will soon bite the dust. — Paul Lienert, Correspondent
