This configuration enhances handling balance and driving dynamics dramatically compared to previous front-engine models. The C8 Convertible features a retractable hardtop roof that can be operated at speeds up to 30 km/h (18 mph), allowing open-air driving without compromising structural rigidity. Power comes from a 6.2-liter V8 engine, delivering excellent horsepower and torque, paired with an 8-speed dual-clutch transmission. The car includes modern tech like a digital cockpit, advanced driver-assistance systems, and customizable driving modes. It blends supercar performance with relative affordability in its segment.
