BMW iX review - Engines, performance and drive

A surprisingly accomplished drive, the BMW iX is hard to fault on the road

While BMW’s all-electric iX3 SUV is based on the combustion-engined X3 model, the bigger iX uses a dedicated EV platform and the manufacturer’s fifth-generation eDrive electric motors. The revised motors are more efficient than the setup found in the aging i3 supermini, and also allow the iX’s torque to be delivered more easily at higher speeds - so you shouldn’t see acceleration tail off as you push on.

If you view the iX in terms of raw power then all seems well, with the entry xDrive40 model offering 322bhp, and the 516bhp xDrive50 and 610bhp M60 providing progressively more punch. What isn’t so great is the iX’s hefty 2.4-tonne kerbweight, which raises a question over the impact on its ride and handling. 

Well, you needn’t worry, because the iX is superb to drive; surprisingly agile through the twisty stuff and providing decent steering feel, it offers bags of grip and fills you with confidence as you turn into a corner. The throttle is easy to modulate, too, whether you’re in slower town traffic or travelling more quickly down an A or B road.

The iX isn’t too shabby on longer motorway journeys, either, where you’ll notice just how quiet the cabin is. There’s no typical electric whine from the motors working away underneath and just the faintest undertone of wind noise when up to speed. All this, coupled with the iX’s ability to soak up almost any bump in the road, makes it difficult to find a negative aspect of how BMW’s flagship electric car drives.

Engines, 0-60 acceleration and top speed

The iX range offers a sliding scale of acceleration times as you climb the range, with the entry 322bhp xDrive40 model laying down a 6.1-second sprint marker from 0-62mph. The xDrive50’s power output rises to 516bhp, along with an increase in torque - from 630Nm to 765Nm. 0-62mph is achieved in 4.6 seconds, while both cars have a top speed of 124mph.

Either of the core iX models should be more than quick enough for most, although if you’re after supercar-rivalling pace, then the 610bhp iX M60 should fit the bill. It dispatches the benchmark run in 3.8 seconds, with a 155mph maximum.
