The latest BMW series 8 is what you call a true successor of a revered lineage -a beautiful symphony of silicon and soul that carves its own legend and paves the path for forthcoming BMW series and rivals luxury grand tourers.

An urbane embodiment of power and grace that offers commendable on-road presence and versatility, a poetic confession from the BMW’s den that fuses long-haul comfort with sports-car acceleration. 

But beware a shortcoming on its way !

Yes, you have read it right. Loophole exists even in a six-figure suave luxury GT. Lets put on your detective coat and detect what’s that flaw that lingers under its unmistakable silhouette.

So, the magic of BMW starts to fade in the interior design. Yes, the same interior that feels like a sanctuary in motion. Actually, it is shortcoming many reviews tiptoe around saying, “it is not much of a big deal” but we believe our valued readers must know the whole truth!

The Interior design appears flashy and plush but it doesn’t break the ground, seems more like an upscale 5 series than a dominant flagship that may disappoint purists and enthusiasts craving cabin drama Porsche or Mercedes offer.

Irrespective of that, BMW 8 Series stands tall with its amazing lineup powered with impressive specifications and unmatchable finesses to seduce purists to modernists craving power + poise.
