The BMW 8 series received a red-carpet welcome amongst the people who still insisted on getting more. After remaining long discontinued for years, the BMW 8 series has stood to the expectations of its customers. In 2021, though, BMW has no new plans for those who are willing to buy a BMW 8 series gran coupe. This successor of the exotic 8 series coupe, with two extra pillarless doors, already offers a lot more to catch one’s mind. However, it's totally unchanged for the upcoming model except for the prices.

The BMW 8 series although having the same DNA stands out from its pack with more evolutions, a twin turbo V8 engine, robust performance, comfort, safety, and advanced tech goodies. Often termed as the “gentleman’s racer” this supreme trim serves to its name in every sense. However, the BMW M850i gran coupe has remained unchanged since the 2019 release but it still manages to look new and fresh everytime in the market. Even with a high fanbase, the BMW M850i Gran Coupe has to compete with the highly capable Lexus LC 500, the mighty Mercedes-Benz AMG S63, and the powerful Porsche 911 Carrera S.

Overall Rating


The 2021 BMW M850i is set to showcase itself in dealers near you, however, it is going to remain unchanged from its previous version and is offered in all three coupe, gran coupe and convertible versions. Some addition to the features list could have better justified the hike in prices. However, it is similarly safe, and drives with the same smoothness and carries the same ride and handling aesthetics of the previous version. BMW still could have worked on the shortcomings of the vehicles, however, the slow demand of the vehicle might have hindered the thought.

Is buying a used BMW M850i Gran Coupe a good idea?

7.0/10

The intelligent engine and powertrain of the 2021 M850i Gran Coupe offer good mpg figures indeed. The figures are made far better and practical than competitors.

2021 BMW M850i Gran Coupe Exterior

9.9/10

The gorgeous looking 8-series BMW of 2020 is being carried over as such to the 2021 model year with a bit more refined look. The sharp front and rear fascia and the bold lines on the hood leave an uncompromised impression in the minds of the spectators. The side profile with the additional rear row helps to distinguish it easily from its two-door sibling.

The wheelbase is longer to improve the interior room to accommodate the passengers in the rear row without congestion. The highlight of the whole exterior design is the stunning long tapering roofline that defines the exact shape to which the Gran Coupe is built. A panoramic sunroof comes standard and an optional carbon-fiber roof is also available.
