The new BMW 7 Series, aimed to rival the Mercedes S-Class, is BMW's latest flagship saloon, superseding the previous 'G11' model with a host of innovative technical features. These advancements are set to later cascade to more affordable BMW models. Built on a tweaked version of BMW's 'CLAR' platform, the 'G70' generation 7 Series offers flexibility in powertrains, from pure combustion to plug-in hybrid and the all-electric i7, with the UK market primarily focusing on the latter two. Dimension-wise, the new model is notably longer, wider, and taller than its predecessor.
