If you're in the market for a large, luxurious SUV with a premium badge, BMW offers two compelling but distinct options: the X5 and the X6. They share the same fundamental engineering, powerful engines, and high-tech interiors, but they're aimed at slightly different buyers.
The X5 is the traditional, practical choice. It's a spacious, versatile SUV with a commanding road presence and the option of seven seats, making it a go-to for families who need space without sacrificing performance. The X6, on the other hand, is all about style. It takes the X5's mechanicals and wraps them in a sleek, coupe-like body that prioritises looks over outright utility. So, is it a case of substance over style, or can you have it all?

Practicality
BMW X5 practicality score: 5/5
BMW X6 practicality score: 4/5
This is where the two cars really diverge. The BMW X5 is a masterclass in practicality. With a huge 650-litre boot, a useful split tailgate, and the option of a third row of seats for seven-person capacity, it's an ideal choice for families. The cabin is spacious and airy, with plenty of room for passengers in the back.
The X6, with its sloping coupe roofline, makes a compromise. While its 580-litre boot is still a good size, it's smaller than the X5's, and the shape of the opening is less convenient for bulky items. More significantly, rear headroom is reduced, and there's no seven-seat option. It’s still a practical car, but if you regularly carry tall passengers or have a large family, the X5 is the clear winner here.
Driving Impressions
BMW X5 driving score: 5/5
BMW X6 driving score: 5/5
Being BMWs, both the X5 and X6 are excellent to drive. They share a range of powerful and smooth six-cylinder petrol and diesel engines, plus some potent V8 options for those who want serious performance. Even the entry-level diesel models provide brisk acceleration and feel effortless on the motorway.
Both cars handle with a precision that belies their size, with well-weighted steering and impressive body control. The standard xDrive all-wheel-drive system provides confidence in all weather conditions. While the X6's sportier styling might suggest it's the sharper car to drive, in reality, there's very little to separate them. Both offer an engaging and comfortable driving experience that’s at the top of the large SUV class.
Technology and Equipment
BMW X5 technology and equipment score: 5/5
BMW X6 technology and equipment score: 4/5
Step inside either model and you're greeted by a beautifully built cabin packed with technology. Both cars feature BMW's excellent iDrive infotainment system, displayed on a large, crisp central screen, alongside a digital driver's display. The system is intuitive to use and comes with Apple CarPlay and Android Auto as standard.
The X5 comes generously equipped from the base model, with features like heated leather seats, air suspension and wireless phone charging. The X6 mirrors this, offering a similar high level of standard kit. The main difference is that the X5 has seen more recent updates, giving it access to BMW's latest Curved Display screen layout and tech features, which gives it a slight edge over the X6.
Running Costs
BMW X5 running costs score: 3/5
BMW X6 running costs score: 3/5
As large, premium SUVs, neither the X5 nor the X6 will be cheap to run. Fuel, insurance, and maintenance costs will be higher than for a mainstream family car. However, there are ways to manage the bills. The diesel engines in both ranges offer respectable fuel economy, capable of around 35-40mpg.
The standout for running costs is the X5 xDrive50e plug-in hybrid (PHEV). With an official electric-only range of over 60 miles, it can handle most daily commutes without using a drop of petrol, and it offers significant company car tax savings. The X6 doesn't have a PHEV option, making the X5 the default choice for those looking to minimise their fuel and tax bills. Both cars come with a three-year, unlimited-mileage warranty.

The Verdict
BMW X5 Overall CarGurus rating: 4.6/5
BMW X6 Overall CarGurus rating: 4.2/5
This is a classic head vs. heart decision, but when you look at the data, there is a clear winner. Based on our comprehensive CarGurus Buyer Insights, the BMW X5 takes the victory. It scores higher with our experts and, more significantly, with owners themselves. It also offers a wider range of powertrains, including the cost-effective plug-in hybrid.
The X5’s combination of a superb driving experience, a high-quality interior, and superior practicality makes it one of the most complete large SUVs on the market. It does everything you could ask of a premium family car, and it does it with real class.
That's not to say the X6 should be ignored. If you love its head-turning, coupe-like design and don't need the extra space or seven-seat capability of the X5, it remains a desirable and impressive machine. But for the majority of buyers, the X5 is the smarter, more versatile, and ultimately better all-round package.
