Expert opinion: how things have changed for BMW

Dino Buratti, Which? cars expert

BMW cars were once famed for their easy-to-use interiors and sheer driving pleasure, but in my opinion the brand has lost some of its shine. That said, its cars still fare better in this respect compared to recent Audi and Mercedes models.

BMW’s decision to introduce its iDrive touchscreen system in 2001 was initially controversial because of how hard it was to use, but thanks to significant updates and refinements it is now one of the most functional touchscreen and control systems of any manufacturer.

While many BMW models still have a rotary controller system for the central screen, it’s sadly missing from some models (such as the X1). Several other BMW cars (such as the BMW 5 Series, pictured below) are now fitted with panoramic displays that integrate the instrument display with the central screen.

BMW’s EVs and PHEVs were initially very innovative – the BMW i3 and BMW i8 ranges caused a stir when they were first introduced over 10 years ago. And while the brand’s electrified cars are still very popular today, many of its rivals (including Mercedes, Smart and XPeng) offer more innovative models that are based on bespoke electric car platforms and have higher rapid-charging speeds.

BMW’s newly launched iX3 electric SUV is its first EV for several years not to be based on a petrol or diesel car, and it has a driving range of up to 500 miles. However, it will face stiff competition from the likes of the Mercedes GLC EQ and Volvo EX60.
