Enthusiasts can now enjoy the soul of a classic 1950s icon with the comfort, reliability, performance and safety of modern 21st-century engineering.”Starke adds that it “prides itself as being at the forefront of the ‘classic car reimagined’ movement, utilizing 3D scanning and Computer-Aided Design to create a custom body that fits precisely over a 718 chassis. Underneath is the option of either a 2.0-liter 300-horsepower turbocharged flat-four, 2.5-liter 350-horsepower turbocharged flat-four, or a 4.0-liter 394-horsepower naturally-aspirated flat-six, with the choice of a six-speed manual or a seven-speed paddle-shift transmission. Virtually the entire drivetrain, suspension and crash structure are carried over directly from the 718, Starke says, including all ADAS features (when optioned with the original exterior rearview mirrors). All modern interior features are retained, too, including heated seats and a heated steering wheel, full power accessories and a power soft top, ensuring the comfort and livability of a modern sports car.”
