The Aston Martin Vanquish is timelessly elegant and carries the strongest engine of the British brand under its hood, a roaring V12. True British power. Also: the tuning company Arden gave a Jaguar a power treatment and transformed the F-Type R to their Arden AJ23 model with breathtaking 650hp. And: a sporty rarity from a traditional manufacturer, the Morgan AR P4 roadster.
