The N420 Vantage came equipped from the factory with a host of unique performance and styling upgrades. Under the hood is a tweaked 4.7L/420hp version of the standard Vantage's V8 (and thus the N420 name), which is backed by a 6-speed SportShift automated gearbox. The N420 also weighs in 27kg lighter than the base car, due in large part to the special carbon fiber body pack (carbon fiber front splitter, side strakes and carbon rear diffuser) and the factory installed Sports Pack with high-performance sport exhaust system.

The luxo-sport theme continues inside the cabin with the handcrafted bucket seats covered in the finest Obsidian Black soft-grain leather with Taylor's Grey Alcantara inserts. Alcantara-trimmed steering wheel, special stitching and N420 logos embroidered in the headrests, N420 sill plaques, and a serial numbered N420 badge under the bonnet reinforce the unique nature of Aston's Vantage N420. This car is further equipped with additionally-optional Satellite Navigation and 700w Premium Audio System, Bluetooth telephone connectivity, iPod integration, optional satellite radio, 6-disc CD changer, auto-dimming mirrors, Double Apex alloy fascia, and the car rolls on 19-inch diamond turned 10-spoke light alloy wheels.
