Morgan Plus Four / Plus Six (CX-Generation)

Production Years: 2019 - 20255 Documented Faults

The CX-Generation represents a revolution for Morgan, replacing the century-old steel ladder chassis with a state-of-the-art bonded aluminium platform while retaining the traditional ash-wood body frame and classic styling. Powered by modern, turbocharged BMW engines (a 2.0L four-cylinder in the Plus Four and a 3.0L inline-six in the Plus Six), they offer vastly improved performance, handling, and daily usability. In the UK, they bridge the gap between vintage charm and modern sports car capability. Reliability is excellent, underpinned by the bulletproof BMW drivetrains. It perfectly suits buyers who want classic looks and craftsmanship but demand modern starting reliability and brisk performance.
