About the Bmw X5 G05
AI-generatedThe BMW X5 G05, launched in 2018, represents the fourth generation of BMW's popular luxury SUV. Built on the CLAR platform shared with the 7 Series, it offers a compelling blend of space, technology, and driving dynamics. The G05 is larger than its predecessor, with improved interior space and a more sophisticated cabin featuring BMW's latest iDrive 7.0 infotainment system. Engine options include efficient diesel and petrol units, plus plug-in hybrid variants (xDrive45e), all paired with an 8-speed automatic gearbox and xDrive all-wheel drive as standard. The G05 X5 combines genuine on-road ability with improved off-road capability thanks to optional air suspension and various driving modes. It seats five as standard, with an optional third row for seven-seat capacity. Build quality is generally excellent, with premium materials throughout and a comprehensive suite of driver assistance systems. The X5 competes directly with the Mercedes-Benz GLE, Audi Q7, and Range Rover Sport, offering a more driver-focused experience than most rivals while maintaining strong practicality and comfort credentials.

Did You Know?
Did You Know?
The G05 X5 is up to 230kg lighter than the previous generation despite being larger, thanks to extensive use of aluminium and high-strength steel
The xDrive45e plug-in hybrid can travel up to 54 miles on electric power alone and achieve over 80mpg in ideal conditions
BMW's Reversing Assistant can automatically reverse the X5 along the same path it drove forward for up to 50 metres - useful in tight spaces
The optional Integral Active Steering (rear-wheel steering) reduces the turning circle by up to 1 metre, making it as manoeuvrable as a BMW 5 Series
Alternatives to Consider
Mercedes-Benz GLE
Direct rival with more refined ride, luxurious interior, but less engaging to drive and similar running costs
Audi Q7
Seven seats as standard, excellent interior quality, more conservative styling but less dynamic handling than X5
Range Rover Sport
Superior off-road ability and prestige badge, but higher running costs and historically less reliable than X5
Porsche Cayenne
More performance-focused with better handling, but significantly more expensive to buy and run with smaller boot
Volvo XC90
More affordable, excellent safety, stylish Scandinavian design, but less sporting and smaller engine options
Owner Tips
- 1Budget for extended warranty coverage, especially for air suspension and complex electronics - typical cost £800-£1,500 annually
- 2Check and top up engine oil regularly between services, particularly on B58 petrol engines which can consume oil within normal parameters
- 3Use premium 99 RON fuel in petrol models for optimal performance and to prevent carbon buildup
- 4Have software updates performed regularly at BMW dealers to prevent iDrive glitches and improve system stability
- 5Inspect valve cover and oil filter housing for leaks during servicing - preventative gasket replacement saves money long-term
- 6For xDrive45e models, charge regularly and use electric mode for short journeys to maximise efficiency and battery health
- 7Service air suspension annually including compressor inspection to catch issues early before major failures
- 8Keep sunroof drains clear by flushing them during servicing to prevent water ingress and mechanism issues
