Can a sports car have four doors and offer the stress-relieving qualities of a luxury saloon? And can a saloon boast so much power and torque? The answer to both questions is a resounding "yes". Every Mercedes-AMG S-Class is a high-end saloon par excellence, after all. The AMG 12-cylinder biturbo engine is under the bonnet, brings a form of driving that is simply unmatched. More assured, dynamic and agile than any performance figures could possibly convey.
