REINVENTING THE WHEEL

AUK-based consortium has been perfecting the in-wheel motors that could represent a step change in EV packaging and production. Mark Tisshaw drives a modified Defender and finds out more

Electromods are not to everyone's taste, it would be fair to say. Take this Land Rover Defender: shorn of all its traditional drivetrain hardware driveshafts, transfer cases, engine, differential locks - is it even a Defender at all any more?

Yet this is an electromod with a difference, because it previews some very real and very relevant technology that could transform electric cars in particular and vehicle design more generally.

The Defender 110 conversion is the work of the Farnham-based Bedeo Group, which comprises battery maker and electric vehicle integration specialist Bedeo and electric motor maker Protean Electric. But it's the Protean part of this story that's most intriguing, as four of the firm's in-wheel motors are fitted to this Defender-based rolling technological showcase.

The perceived primary benefit of such motors is the far more precise control of each wheel they offer, and that's true of them here in this Defender. Yet those benefits are secondary in the long run, as in-wheel motors pave the way for a revolution in architecture design. They would allow car makers to do away with axles, driveshafts and subframes, in turn reducing overall mass and therefore cost because smaller batteries can be fitted and packaged in such a way that needn't make the EV so tall. Put simply, in-wheel motors help cars get lighter, smaller and cheaper.
