Billie: Ringbrothers' 650-HP Carbon-Fiber 1965 Pontiac GTO Debuts at SEMA

Ringbrothers, the Wisconsin-based custom car builder, unveiled its latest creation at the 2024 SEMA Show in Las Vegas: a heavily modified 1965 Pontiac GTO named 'Billie.' The build features extensive carbon-fiber bodywork that reduces weight, and it is powered by a supercharged LT4 V-8 engine producing 650 horsepower. The car combines classic muscle car styling with modern performance and materials. This project highlights the ongoing trend of restomodding classic American cars with contemporary drivetrains and lightweight composites. The SEMA debut underscores Ringbrothers' reputation for high-end, bespoke builds that push the boundaries of automotive customization. Billie is a showcase of craftsmanship and engineering, likely to inspire enthusiasts and builders alike.
