BMW 428i vs BMW X5

What's the difference?

Tim Robson road tests and reviews the BMW 4 Series with specs, fuel consumption and verdict at its Australian launch.

Following on from the mid-life tweaks to BMW's mainstay 3 Series in December 2015, the spin-off 4 Series line has now been updated along the same powertrain and equipment lines.

Based on the same mechanicals as the 3 Series, the three-year-old 4 Series was ostensibly formed to give BMW's nomenclature some sense of logic by designating its two-door machines as 'evens' (2 Series, 4 Series and 6 Series) and its four-door cars as 'odds'.

Three variants currently make up the 4 Series range, including a two-door Coupe, a two-door Convertible and – oddly, given the naming regime – a four-door Gran Coupe that also sports a hatch-like tailgate.

The BMW X5 is a leading contender in the ‘Over $70K Large SUV’ division of Australia’s new car market, which is a hotly-contested segment boasting 15 marques and 25 models.

The X5 has hit an enduring sweet spot with Aussie buyers in terms of size, performance and price. BMW prefers to call it a Sports Activity Vehicle (SAV) as distinct from its Sports Utility Vehicle (SUV) rivals.

Clearly, any word association with a utility is something BMW Group Australia wants to avoid after recently launching its latest X5 range, which brings numerous enhancements including design revisions, increased standard equipment, refreshed powertrains and more.

We were entrusted with the digital ‘Comfort Access’ key to one of the latest X5s, to understand from a family car perspective why this model range enjoys such enduring popularity with prestige SUV (sorry, SAV) buyers.
