The V8 Vantage Roadster is the drop-version of Aston Martin's entry-level V8 Vantage sports car. It isn't the quickest or best-handling convertible on the market, but the V8 Vantage Roadster does boast some of the sexiest sheetmetal ever fitted to a automobile.
The V8 Vantage Roadster is powered by a hand-assembled 4.7 liter naturally aspirated V8 producing 420 horsepower at 7,000 rpm along with 347 lb-ft at 5,000 rpm. The high-revving V8 is mated to a choice two transaxles, both of which are equipped with a limited-slip differential.
The first is a traditional manual with six forward gears, while the optional transaxle is a new seven-speed Sportshift "automated-manual." Aston says the Sportshift provides faster and more precise shifts than the old six-speed unit, but the gearbox still sports an old-fashioned single clutch design (many competitors have switched to super-quick dual-clutch transmissions).
A top speed of 180 mph is possible, and good handling on the track is ensured by a 49/51 front/rear weight distribution. Aston Martin claims the car will reach 60 mph in 4.7 seconds with the standard transmission, while another important performance metric - the total closing time of the top - is only 18 seconds. The cloth top features a heated glass rear window, and as the coupe is a two-seater anyhow, the only thing it takes away from is cargo capacity.
Fuel economy isn't likely to be of prime importance for most buyers, but, for the record, the V8 Vantage returns 14/21 mpg and 13/19 mpg with the automatic and manual transmissions, respectively.
Stopping power is increased thanks to new 380mm two-piece ventilated cast-iron front discs and six piston calipers along with 10mm wider tires. A re-valved power-steering pump and a quicker ratio of 15:1 (compared to 17:1) give the V8 Vantage a more responsive helm, while a new Hill Start Assist system works to prevent rollback on steep hills.
A Sport Package is available for those who demand only the best performance from their Aston Martin. The Sports Pack features forged lightweight alloy wheels, re-tuned Bilstein dampers, up-rated springs, and an anti-roll bar for the rear. the combined effects of the Sport Pack result in a vehicle that is better behaved at higher speeds.
As one would expect of the brand, even the smallest Aston Martin comes luxuriously equipped and includes full grain leather seating surfaces with alcantara inserts and headliner, electronic climate control, tire pressure monitoring system, and a 160-watt six-disc audio system capable of playing audio from mobile devices thanks to an iPod interface and USB connection. There is an optional 700-watt Aston Martin premium audio system with Dolby Pro Logic II support for those for whom the sound of that V8 engine is not enough.
Other major options comprise 19-inch wheels, an improved Hard Disk Drive navigation system, satellite radio, Bluetooth communication interface, and Xenon HID headlights.
V8 Vantage GT Roadster
The GT boasts the uprated 4.7-liter V8 from the Vantage S that produces 430 horsepower and 361 lb-ft of torque. With the help of either a standard six-speed manual - a transmission that Aston has purged from many of its other models - or an optional seven-speed, single-clutch automated manual, that output is enough for a zero-to-60 mph sprint of 4.6 seconds and a top speed of 190 mph.
A stiffened suspension similar to that of the Vantage S is also part of the package.
Black exterior trim, clear-lens taillights, Vantage S side sills and graphite painted, diamond-turned 19-inch wheels give the GT a unique look. Buyers can also spec an exterior appearance package that evokes Aston's racing heritage with contrasting grille "lipstick," mirror caps, A-pillar rails and rear diffuser blade.
Interior upgrades include sports seats cribbed from the V12 Vantage S, "Plisse" Alcantara trim, machined carbon sill plaques and black magnesium paddle-shifters or a carbon fiber gearshift surround.
All V8 Vantage Roadster models are fitted as standard with dual front and side airbags in addition to traction and stability control systems. There are also pop-up rollbars that protect occupants' heads in the unlikely event of a rollover situation.
Drop-top rivals to the V8 Vantage Roadster include the high-performance Porsche 911 Carrera S Cabriolet, the charismatic Maserati GranTurismo Convertible and the Mercedes-Benz SL550, which offers the versatility of a hard-top convertible configuration.
