Twin-Charging Explained: Why Certain Automakers Paired Turbochargers with Superchargers

Twin-charging blends a mechanical supercharger with an exhaust-driven turbocharger to provide instant low-end throttle response while preserving top-end power. Though engineering icons like Lancia and Volvo famously adopted the complex setup to maximize smaller internal combustion engines, modern powertrains have largely shifted toward electric assist and hybrid systems to bridge performance gaps.
