BMW iX vs Audi e-tron Sportback: verdict and specifications

It’s a clear win for the BMW iX here, which bests the Audi e-tron Sportback in almost every area

BMW iX vs Audi e-tron

This twin test has served as a very clear illustration of how quickly electric-car technology and design are advancing. While the e-tron was an impressive contender at the time of its launch, it and other cars like it built on combustion-engine platforms are starting to be eclipsed by a new generation of EVs that sit on dedicated electric architecture. Admittedly, the iX’s looks could be an insurmountable barrier for some, but under its curiously shaped metal it’s an extremely impressive and accomplished luxury electric SUV.

1st: BMW iX – 4.5 stars

The iX is a stunning achievement for BMW and bodes well for future electric models from the brand. It’s very refined and comfortable, has a powerful and efficient drivetrain, boasts excellent in-car technology, has plenty of space for passengers and luggage and – perhaps most importantly for a BMW – handles well, too. For those with plenty of cash to spend, it’s a close-run thing between the iX and Porsche Taycan for the title of ‘best electric car you can buy right now’. Read more in our full review.

2nd: Audi e-tron Sportback – 3.5 stars

It seems like only yesterday that the Audi e-tron was the impressive new kid on the electric SUV block, but automotive development is moving fast these days. Many will prefer the Audi’s more traditional looks, and it has the edge over the BMW for practicality, but when it comes to vital areas such as range, efficiency, on-board technology, comfort and handling prowess, the e-tron Sportback is simply outclassed here.
