Overview

The BMW 8 Series Convertible is the brand’s flagship open-topped car. It’s a four-seat, drop-top version of the 8 Series Coupe, and is meant to rival some of the very best convertible cars on sale today.

BMW promises that the 8 Series is as refined and as engaging as the Coupe that it’s related to, which is quite a claim given that the act of removing a roof always brings compromises. Certainly this and the car’s near six-figure starting means high expectations of a car that can be both fun to drive and superbly luxurious – equal parts sports car and grand tourer.

The competition at this level is exceptionally good, too. The headline competitor is of course the brilliant Porsche 911 Cabriolet – with decades of DNA and driving dynamics at the forte. There’s also the new Mercedes SL, which offers a sportier focus and plenty of in-car tech. Or for a left-field option, Lexus offers the spectacular-looking LC Convertible, with a naturally-aspirated V8 and distinctly old-school feel.

The 8 Series Convertible range has been slimmed down since launch. There are three engine options each tied to their own trim level. The entry-level M Sport 840i uses a 3.0-litre straight-six and as you’d hope comes very well-equipped as standard with niceties such as adaptive LED headlights, Harman Kardon stereo, heated seats, climate control and various assisted driving features.

The M850i and ballistically powerful M8 Competition use a 4.4-litre V8 engine and add adaptive suspension, four-wheel drive and four-wheel steering. On the options list you’ll find things like upgraded ‘Laserlight’ headlights, a more powerful Bowers & Wilkins stereo, seat ventilation, and even BMW’s ‘CraftedClarity’ package – which gives you selected interior switchgear made of pure crystal. Classy.
