The BMW 5 Series needs no introduction. Through seven generations, it has set a high bar for quality, driveability and executive comfort. So how much improvement can a new generation bring? As it turns out, quite a lot.

The eighth generation model has grown larger in size, and with the relevant design changes to emphasises its imposing presence. The illuminated Iconic Glow kidney grilles come as standard, while a sleek and clean rear end accentuates the car’s new-found proportions.

Inside, the 5 Series receives many of the modern amenities found in the flagship 7 Series, including the Curved Display and Interaction Bar. Notably, the car runs the updated Operating System 8.5, which has a much more intuitive user interface through which a wide range of functions are accessed.

Quality and luxury has also been taken up a notch. Beyond just the materials and fit-and-finish, which are expectedly high quality, classy appointments like the fine-wood trim deliver an improved sense of classiness.

On the road, the new 5 Series’ greatest calling card is a new-found comfort and cushiness. Considering it is over five metres long, it’s hard to imagine it being lithe and compact. Instead, the 5 Series leans into ride comfort – supple and fuss-free over bumps, quiet and cosseting when on the move, all helped on by a refined 2.0-litre mild-hybrid engine producing 187bhp and 310Nm of torque.

In its eighth generation, the BMW 5 Series delivers increased space and cabin comfort, coupled with an upgrade in interior technology and functionality. With its plush ride and serene driving experience, it also brings an increased sense of luxury and quality. Considering its high levels of refinement and equipment, the new 5 Series is our Most Improved Car of the Year.
