The Bentley Arnage will celebrate a decade of aristocratic motoring with a 150 car final series production run. Due to commemorate 10 years of the Arnage, 50 years of its anachronistic pushrod V8 engine and 90 years of the Bentley marque, VW’s British luxury division will launch its limited edition model at the Paris Motor Show next week. Hardly a stickler for originality it’s called the Bentley Arnage Final Series. Bentley says you get the performance of an Arnage T blended with the refinement of an Arnage R garnished with design elements from the Brooklands coupe.Perusing the specification sheet you’ll come to the conclusion it’s a marketing exercise dabbling in exterior and interior trim upgrades. Old school performanceAesthetically the Final Series features a retractable ‘Flying B’ bonnet mascot, body coloured headlamp bezels, lower front wing air vents, obligatory ‘Final Series’ badging and a ‘Jewel’ fuel filler cap. Overall the right-hand lane overtaking presence is still fearsome, and it should be with 372kW and 1 000Nm on tap from the 6.75-litre turbocharged V8.The lumbering pushrod V8 powers the Final Series from 0-100km/h in 5.5 seconds on its way to a 288km/h top speed. Effortless performance is the overriding characteristic though, and equipped with a six-speed ZF sourced automatic transmission, the Final Series surges forward without drama thanks to 1 000Nm of torque being available at only 3 200r/min. Chassis dynamics are predisposed to providing seamless ride quality of the highest order – despite riding on 20-inch wheels. Thanks in part to a fully independent, double wishbone front and rear damping set-up with electro-hydraulic ride height control the 2585kg Final Series manages to blend superb ride comfort with some remnant of handling fluidity. Bespoke interiorBentley owners live and die by the bespoke nature of their interior customisation options, and with the Final Series it's quite a contemporary state of affairs. Beyond the tacky Final Series treadplates, flasks and shot glasses there is a practically limitless choice of unbleached wood veneer finishes. A stylish cocktail cabinet hides tax evasion flowcharts, whilst the four Bentley branded umbrellas make for stylish pavement to penthouse transition even during inclement weather.Disappointingly the ten speaker, 1 100watt Nain surround audio system and iPod connectivity are optional. Seemingly you can’t always have your cake and eat it. The Final Series will be limited to a run of 150 cars.
