Mercedes unveils powerful new AMG 4.0-litre twin-turbo V8

By John Mahoney Motor Industry 25 July 2014 17:09 Mercedes AMG has released details of an all-new 503bhp 4.0-litre twin-turbo V8 that will help fill the void when the production of its normally aspirated 6.2-litre V8 ends. Lightweight, compact and more efficient than the big 6.2-litre it replaces, the new smaller capacity turbocharged V8 produces 479lb ft from just 1750rpm.

Like many of the latest generation of convertibles, the Cascada ditches a folding solid hardtop in favor of a lighter, more space-efficient and cheaper soft fabric set-up.
