As the most powerful model in Mercedes' stable, the S65 AMG isn't a car you would think owners would want to try and eek more power from. The super sedan comes stock with a 6.0-liter twin-turbo V12 delivering 630 horsepower and 737 pound-feet of torque, but hardcore owners wanting more can head to German tuner Voltage Design to boost output to either 680 hp ($3,899 Euros) or to a massive 720 hp and 848 lb-ft.
The bigger power package (7,899 Euros) will help the S65 hit a top speed of 199 mph, while both kits come with racing air filters, custom downpipes and an unlockable top speed module. On top of that, Voltage offers a carbon-fiber aerodynamic body kit priced at 24,900 Euros made up of a front splitter, side skirts, roof spoiler and diffuser. A new carbon-fiber hood is an additional 3,000 Euros. Other upgrades include carbon-ceramic brakes (14,850 Euros), and a set of 21-inch alloys.
