Summary
The original BMW 8 Series first appeared in 1990 as the German brand’s largest two-door coupe, but by 1999 it was not selling well and was dropped.
Two decades later, BMW decided there was now room for a luxury grand tourer with enormous power, in 2018 launching an all-new 8 Series in coupe and soft-top convertible body styles. Later a four-door Gran Coupe was added to the range – we are building a separate page for this version, so check back soon.
There are two petrol engine options or a diesel and all are potent. The 840i puts out 333hp, while diesel fans get 340hp and an all-wheel drive powertrain.
Most rapid of all is the M850i ,with 530hp, put through the all-wheel-drive to produce a blistering 3.8-second 0-62mph time. It’s not the quickest, however, as BMW also offers an the M8 (also not covered by this rating; we’ll add this to our index soon).
Reviewers focus on the 8 Series’ luxury, its potency and price – the Telegraph believes BMW has pitched its car as “a piece of high-performance automotive art, with the emphasis on performance”. Mind you the review adds that such cars with big engines are about to be killed by emissions regulations.
The price exercises the Mirror’s reviewer too, who argues that the 8 Series might “depreciate savagely and within a decade you’ll be able to pick one up for pennies.”
Top Gear sums the 8 Series as possibly the ultimate car for those who like BMWs – “but it is less special than its rivals”. However the Daily Mail, testing the convertible with its top that opens or closes in just 15 seconds, argues that it is; “a sensational luxury grand tourer for those old and experienced enough to appreciate the good things in life – more mature than a regular sports car.”
As of December 2024, the BMW 8 Series holds a New Car Expert Rating of D, with a score of 57%. Although the media reviews have been positive, the 8 Series is a brutally expensive car to live with. Currently, we don’t have safety or reliability data, so check back soon.

“The BMW 8 Series Convertible is a rare thing: a luxurious open-top GT that’ll put a smile on your face around corners. There’s only really room for two, though, and the petrol is thirsty.”

“As a flagship coupe or convertible, the BMW 8 Series ticks many boxes. It’s loaded with technology, features a luxurious cabin and has proper presence on the road. It’s let down by a lack of handling sharpness, cramped rear seats and eye-watering prices.”

The Telegraph
Model reviewed: Convertible
“For all its remarkable qualities, however, I found it hard to love this car. There’s a slight end-of-days ostentation about it, which seems to bring out the worst in fellow road users. You might even observe that this car is too expensive and too accomplished to be a “proper” sports car, which should extract a penalty in practicality and accommodation.”

“Something of an iron fist in a velvet glove. Technology allows this two-door luxury coupé to have a dual personality, which combines old-school road-burning performance with a refined and comfortable cruising ability. This isn’t a big market, but BMW has invested heavily to get back into it and the BMW 8 Series is a credible contender.”

“In BMW language, a GC is a four-door coupe-ish thing. In this case a version of the ritzy 8 Series coupe, with added doors. It’s not just some lazy stretch job. Every exterior panel is different aft of the windscreen.”

The BMW 8 Series has expensive running costs, according to data exclusively provided by our partner Clear Vehicle Data. Petrol models offer 30mpg, which is low compared with the rest of the market. Diesel variants are much more efficient.
Insurance premiums are predictably more expensive than the market average, and service and maintenance costs over five years are more expensive than other models in BMW’s range.
