Review: BMW 8 Series Convertible – Luxurious Performance and Style

The BMW 8 Series Convertible offers a luxury escape with high structural rigidity yet light materials, positioning it against models like the Bentley Continental GT Convertible and Mercedes-AMG SL. Available with either a six-cylinder or a powerful V8 engine, it excels as a grand tourer but not a true sports car. The M850i version stands out for its performance, featuring a twin-turbo V8 and all-wheel drive. While the interior is understated compared to rivals, BMW’s latest iDrive infotainment system impresses. Front space is ample, but rear seating is limited. The 8 Series balances luxury and performance, offering good value compared to high-end competitors.

BMW 8 Series Convertible: A Luxurious and Dynamic Ride


When it comes to luxury convertibles, cars like the BMW 8 Series Convertible provide a true tonic for the soul. With one in your driveway, the prospect of an escape is just at your doorstep—grab the keys, drop the top, and head off to where the skies are bluer and the grass greener.

At the heart of the 8 Series Convertible lies a platform that ingeniously combines high-strength steel, aluminum, magnesium, and carbon fiber-reinforced plastic. This strategic mix keeps the weight low while ensuring high structural rigidity. Yet, despite BMW’s reputation as the manufacturer of the Ultimate Driving Machine, the 8 Series boasts quite a large footprint.

While it leans more towards luxury than sportiness, the BMW 8 Series still holds its ground against rivals like the Bentley Continental GT Convertible, Lexus LC 500 Convertible, and Mercedes-AMG SL. Available with either a sleek six-cylinder petrol engine or a robust V8 powering all four wheels, the 8 Series Convertible never fails to impress.

Performance and Drive

Despite sharing an engine with the BMW M5, the BMW 8 Series Convertible M850i has a detuned version, but trust us, it’s still thrilling. The 4.4-liter twin-turbo V8 delivers superb refinement and response, aligning perfectly with the grand touring spirit of this open-top marvel. With 523bhp, the M850i is effortlessly powerful, and its xDrive four-wheel drive ensures you can deploy all that power with ease, even when roads open up.

However, the engine note isn’t quite as thrilling as the V8 in the Lexus LC 500 Convertible. That being said, the V8 engine of the M850i is undoubtedly the go-to option when craving power and refinement. And for those even more performance-oriented, the BMW M8 Convertible is worth considering.

With the roof up, some road noise and wind whistle make their presence known at 70mph, but it’s nearly as refined as its hardtop sibling. It’s also vastly quieter than the Mercedes-AMG SL—less wind and road noise permeate the cabin. With the top down, its wind deflector does a commendable job, even allowing conversations at highway speeds.

The 8 Series Convertible’s rigidity stands out, handling rough surfaces well with minimal body flex. Thanks to the inclusion of four-wheel steering, a clever eDiff on the rear axle, and optional M Adaptive anti-roll bars, it feels engaging and nimble.


Stepping into the 8 Series Convertible reveals an interior that may be less dramatic than its exterior but is still exceptionally refined. Expect BMW’s signature understated elegance rather than flashy designs, ensuring exceptional build quality. From the precise stitching on the leather dashboard to brushed chrome trim pieces, everything feels well-honed and luxurious.

The centerpiece of the interior is the excellent iDrive infotainment system with its 12.3-inch touchscreen. It’s intuitive, responsive, and complements well with the rotary controller, making it effortless to use. Standard features include Android Auto and Apple CarPlay, along with another 12.3-inch digital instrument display and a head-up display.

Passenger and Boot Space

In terms of space, the front seats of the BMW 8 Series Convertible offer ample head and legroom for tall occupants. The back seats, however, provide minimal legroom—better suited for bags rather than people. The boot delivers a reasonable 350 liters of space, sufficient for small suitcases but too shallow for anything bulky.

Buying and Owning

Positioned at the premium end of the market, the BMW 8 Series Convertible offers good value relative to its rivals. The 840i is cheaper than the Porsche 911 Cabriolet, and the top M850i undercuts the Mercedes-AMG SL 55 and Bentley Continental GT Convertible. For those favoring V8 engines, the Lexus LC 500 Convertible remains an excellent value proposition.

Reliability and Safety

While the 8 Series Convertible hasn’t been crash-tested by Euro NCAP, it comes with a robust suite of active safety aids like automatic emergency braking (AEB), lane-keeping assist, and blind-spot warning. BMW’s reputation for reliability places it mid-pack among luxury brands, with a three-year unlimited mileage warranty as standard.
