Mercedes AMG C63 Cabriolet Is One Bad Mother
In 2015 Mercedes AMG released the updated C63 to the public in their typical fashion of giving the public access to the 4-door sedan first and then roll out the coupe.
The C63 is now going to be delivered in a cabriolet version making a whopping 503bhp. The C63 is powered by a 4.0-liter twin-turbo V8. The C63 is electronically capped at a 155mph limit but can be bumped to 174mph if you purchase the AMG Driver’s Package from the factory.
