The Bentley Arnage was a large luxury car produced by Bentley Motors in Crewe, England from 1998 to 2009. The Arnage, and its Rolls-Royce-branded sibling, the Silver Seraph, were introduced in the Spring of 1998, and were the first entirely new designs for the two marques since 1980.
Following the uplift in sales for all of Rolls-Royce, and resurgence of the Bentley marque, the then-owner, Vickers, set about preparing a new model to replace the derivatives of the Rolls-Royce Silver Spirit/Bentley Mulsanne which it had been selling since 1980. In a complete switch from tradition, these new cars would have bodies built at the Crewe factory, with its internal combustion engines built elsewhere.
Bentley marked its 60 years of production at the Crewe factory with a special Diamond Series Arnage in 2006. 60 vehicles were planned, the majority for the United States, with diamond wood inlays, diamond quilted leather seats, a stainless steel front bumper, special 19 inch alloy wheels, and Union Jack badges on the front wings.
In September 2008, it was announced that Arnage production would cease in 2009, once a final run of 150 "Final Series" models has been completed. The Arnage Final Series includes the Arnage T powertrain, including the aforementioned twin-turbo 6.75-litre V8 engine that produces 500 metric horsepower (368 kW; 493 bhp) and approximately 1,000 newton metres (738 lb·ft) of torque. The powertrain delivers torque to the rear wheels via a six-speed ZF automatic transmission.
