Performance

Being a plug-in hybrid, the X5 xDrive 45e has two power sources – a 2,998cc six-cylinder petrol engine that generates 282bhp and an electric motor that produces 111bhp. Together, they give the X5 a total power output of 389bhp with a total torque figure of 442 lb ft. Power is fed to all four wheels via an eight-speed automatic. As we’ve come to expect from BMW hybrids, the X5 45e’s power management system is remarkably efficient and somehow manages to blend petrol power with electric power seamlessly. Despite tipping the scales at more than two and a half tonnes (2,510kg to be precise), the X5’s huge reserves of power make it feel like half that. If defeat in the traffic light grand prix is likely to spoil your day, you’ll be pleased to know that the X5’s 0-62mph time of 5.6 seconds is likely to see off most competition. And if mid-range flexibility is more your thing, the X5’s ability to deliver instant chunks of acceleration makes it feel exceptionally lively. 

Drive

Despite its incredible complexity, the X5 45e is refreshingly simple to drive. If drive modes and menus bore you to tears, you can simply stick it into Drive and let the car’s electronic brainpower do the rest. However, if you want to tailor the driving experience to your needs and potentially get more out of the car in terms of performance or range, BMW offers a number of different modes. Drivers can choose between Sport, Electric, Hybrid and Adaptive, and there’s a fifth mode called Sport Individual hidden in the menus for those who want to play even more. There’s also a button called ‘Battery Hold’ which allows you fill up the battery to 100% during normal driving to use later on. In normal driving, the X5 alternates between electric and petrol power, mixing both to give the optimal driving experience. However, selecting Electric mode locks out petrol power and allows you to run on battery for as long as the charge lasts.
