BMW 8 Series (2018-present) Pros and Cons

Pros	Cons
Quick, and handles well	Not as exciting as a Porsche 911
xDrive 4x4 models perform in all weathers	Not as luxurious as a Mercedes S-Class Coupe
Choice of convertible, coupe, and four-door body styles	Coupe and convertible are cramped in the back

Quick Summary

The BMW 8 Series (2018-present) serves as BMW's flagship, blending sporting prowess with luxury as a grand tourer. Available as a coupe, convertible, or the more practical four-door Gran Coupe, it aims to strike a balance between the outright sportiness of a Porsche 911 and the opulence of a Mercedes S-Class Coupe. While its size and weight lean it towards a grand tourer, especially in M8 Competition guise, it offers truly breathtaking acceleration and lusty performance across the range. Interior quality is generally opulent, and the iDrive infotainment system is a strong point, though rear space in two-door models is limited. Running costs vary significantly; the 840d can achieve around 40mpg, while the M8 Competition manages closer to 22mpg. All models incur a £475 annual road tax, with higher first-year rates for powerful petrol variants. Insurance is consistently high, falling into group 44 or above. Despite potentially high servicing and tyre costs, BMW offers fixed-price service plans to manage maintenance expenses, making it a luxurious yet manageable performance choice.

Best for: Drivers seeking a luxurious grand tourer with strong performance, those who want a blend of sportiness and comfort, buyers desiring BMW's flagship model, or an incredibly fast road car (M8 Competition).

Not ideal for: Buyers prioritising outright sports car agility (like a 911), those needing generous rear passenger space in two-door variants, or those seeking the ultimate in interior luxury and architectural design (like an S-Class Coupe).


Comparison vs Key Rivals



The Verdict

You should buy the 8 Series if: You're seeking a luxurious grand tourer with strong performance, a blend of sportiness and comfort, or BMW's flagship model.

Consider alternatives if: You prioritise outright sports car agility, generous rear passenger space in two-door variants, or the ultimate in interior luxury and architectural design.

Competitive Position: The BMW 8 Series (2018-present) successfully carves out a niche between the pure sports car (Porsche 911) and the ultra-luxurious coupe (Mercedes S-Class Coupe). It offers a compelling blend of powerful performance, opulent interiors, and striking design across its coupe, convertible, and Gran Coupe body styles. While it doesn't excel in outright track performance or rear passenger space in two-door variants, its versatility, advanced infotainment, and grand touring capabilities make it an attractive option for those seeking a sophisticated and high-performance luxury vehicle that stands apart from its more focused rivals.
