BMW i4 Review

Written by Allan Noble · 16/09/21

The new BMW i4 has been designed by the German carmaker from the ground up and it certainly feels like something of a game-changer in all-electric vehicles. Will this set the standard with electric cars? Read our BMW i4 review and find out for yourself!

Summary

To begin with, the BMW i4 prototype was only unveiled as recently as 2017. Back then, the BMW i4 prototype was the first all-electric designed by BMW's motorsports division. However, the BMW i4 prototype has now morphed into an electric car that is just as much at home on the road as it is on the track. The new i4 may be built on the same platform that the carmaker has already used for some of its other electric cars but that does not mean that this 2021 BMW isn't something very different as, in fairness, most car reviews thus far have pointed out. Overall, this is BMW's liftback style of saloon with styling that would make owners of the 3 series drool. BMW claims that the four-door saloon counts as a gran coupé and it certainly falls into that general bracket. The wheelbase is 2,856 mm long while the weight of the car varies from 2,125 kilos to 2,290 kilos depending on the model variant you buy.

Range, Charging, & Emissions

Firstly, the BMW i4 will provide 316 miles of driving under WLTP, or test conditions. The battery technology BMW has chosen makes use of a high voltage system, allowing for fast charging. This means the battery pack conforms to the fifth-generation i4 eDrive40 system. The car has two main versions, the single motor i4 eDrive40 and the twin motor M50. Both have an 81.5 kWh battery to run the electric motor. What most i4 news reviews fail to point out, however, is that the lithium-ion battery pack offers 83.9 kWh gross power output. This constitutes 40 per cent more volumetric density than you'd find in a BMW i3 because extra battery modules adding up to 72 cells each have been fitted. Fortunately, they're all hunkered down in the car so that the centre of gravity remains low in the i4.

As for charging, the full 367 miles of range can be obtained from zero within eight hours or 13 hours from a 7.4 kW wall box. However, with fast-charging outlets, the car will be able to accept loads of up to 200 kW. Accordingly, the i4 edrive40 is said to be able to offer a 102-mile charge up within just ten minutes. The equivalent distance for the M50 is 87 miles for the same length of time charging. Indeed, a 10 per cent to 80 per cent charge would be possible in a little over half an hour when using a 200 kW charging station. This is something that is likely to make the ears of any electric car buyer prick up!
