Mercedes-Benz unleashed on the web today their all-new 2015 S65 AMG Coupe, a big brother to their recently revealed S63 AMG Coupe. Without straying too far from the S63’s overall appearance, the new S65 features flashy yellow brake calipers, a different set of 20-inch wheels, a sparkling mesh grille, and a more distinguished rear diffuser. Under the hood there’s a V12 6.0-liter twin-turbo engine with 738 pound-feet of torque and 621 horsepower. The S65 boasts a clocked 0-62 mph in just 4.1 seconds before capping off at 186 mph in the United States; 155 mph in Europe. Additional features to mention is the car’s Designo Nappa leather sport seats, a seven-speed AMG Speedshift, and a Magic Body Control suspension system for easy handling into sharp bends. The Mercedes-Benz S65 AMG Coupe will drop later this year with a hefty price tag of around $250,000 USD, so keep an eye out.
