The story

The M8 opens its roof.

The M8 Competition Convertible pairs the twin-turbo V8 with a folding fabric roof. It is a distinct body configuration from the F92 Coupé, so mass and acceleration should be compared in context.

Best for

Open-air V8 grand touring.

Trade-off

Roof hardware and seals need checks alongside the powertrain.

The F91 roof is fabric, rather than a folding metal hardtop.
