Not long after the 2014 Mercedes-Benz S63 AMG debuted, its big brother, the Mercedes-Benz S65 AMG was recently spotted testing completely undisguised at the Nurburgring.
Details about the 2014 Mercedes-Benz S63 AMG are fairly limited at the moment, but it’s expected to feature a 6.0-liter twin-turbocharged V12 engine pumping out an impressive 630hp and 737lb-ft of torque. An official debut is expected at the upcoming IAA Frankfurt Motor Show 2013 next month!
