Ferrari’s all-new & forthcoming 812 GTS is basically the drop-top variant of the brand’s 812 Superfast. Powered by the same naturally aspirated 6.5-liter V12, this new open roof roadster cranks out 789 horsepower and 530 pound-feet of torque, making it the most powerful convertible on the market. Top speed: 211MPH. 0-60: sub three seconds. Even though it really should be manual shift, all that power is transferred to the tires through a 7-speed dual-clutch transmission.
