(+Ex-Factory Price)The BMW M8 Competition Convertible is an open-top four-seat grand tourer for Australian enthusiasts who want the sound and performance of a 460 kW twin-turbo V8 with the added theatre of a fabric roof that can open or close in about 15 seconds, while M xDrive, an eight-speed M Steptronic transmission and 750 Nm provide rapid all-weather traction and a 0–100 km/h time of approximately 3.3 seconds. It combines a richly finished cabin, neck-warming comfort, adaptive M suspension and configurable driving modes with genuine interstate ability, but the roof mechanism adds weight and reduces luggage space compared with the coupé. Because BMW Australia no longer lists the M8 Convertible in its current open-order range, local buyers should compare remaining stock and BMW Premium Certified cars carefully for roof condition, service history, option content, tyre and brake wear, warranty commencement and any previous cosmetic or structural repair.
The BMW M8 Competition Convertible applies BMW M’s flagship V8 performance package to an open four-seat body. Its 4.4-litre twin-turbocharged engine produces 460 kW and 750 Nm, paired with an eight-speed M Steptronic transmission and rear-biased M xDrive. BMW quoted 0–100 km/h in approximately 3.3 seconds, only slightly behind the lighter coupe, while the electronically controlled drivetrain provides strong traction in dry or wet Australian conditions.
The multi-layer fabric roof is designed to preserve the 8 Series’ long, low profile and can open or close in around 15 seconds, including while the vehicle is moving slowly. With the roof raised, insulation is strong enough for comfortable highway travel, while lowering it exposes the V8 soundtrack and creates the model’s main emotional advantage over the coupe. Buyers should remember that the roof mechanism, extra body reinforcement and rollover protection increase weight and reduce luggage capacity.
Driving technology includes adaptive M suspension, M Servotronic steering, an Active M Differential and configurable engine, damper, steering, brake and transmission settings. M xDrive offers 4WD and 4WD Sport modes, with a rear-wheel-drive setting available only after the stability system is disabled. This flexibility allows the Convertible to behave as a secure grand tourer in normal use while still offering the response and adjustability expected from a full BMW M model.
The cabin provides two spacious front seats and two compact rear seats. Merino leather, M-specific digital displays, a head-up display, navigation, wireless connectivity and premium audio were included or commonly specified on Australian cars. Front-seat heating and neck-level warming make roof-down driving more comfortable in cooler weather, while optional M Carbon bucket seats create a more focused feel but can make entry and long journeys less comfortable for some occupants.
The M8 Competition Convertible is no longer shown in BMW Australia’s current model catalogue as an open factory-order car. Most available examples will therefore be used, BMW Premium Certified, demonstrator or remaining dealer stock. The build date, compliance date and warranty start should be checked because a low-kilometre vehicle may still have been registered well after production. Factory build records are also valuable because individual paint, carbon packages and ceramic brakes can change both value and future repair cost.
Pre-purchase checks should include the roof fabric, seals, drains, hydraulic or electric operation, wind deflector and any water staining inside the cabin or luggage area. The V8 cooling system, transmission, all-wheel-drive hardware, adaptive dampers, tyres and brakes also require specialist assessment. Owners should budget for roof care, battery maintenance during storage, premium fuel and the possibility of imported replacement components. Secure covered parking is particularly important in harsh Australian sun and heavy summer rain.
For Australian buyers who prioritise open-air performance and luxury, the M8 Convertible remains a compelling flagship. It is refined enough for interstate touring and dramatic enough for special-occasion use, but it is less practical than the coupe and carries substantial fuel, insurance, tyre, roof-maintenance and servicing costs. The strongest purchase is a locally delivered example with complete history, carefully documented options and no evidence of neglected roof or chassis maintenance.
