Matt Prior: why electrical SUVs will rewrite the off-road rulebook


I am intrigued by James Attwood’s current drive of the Audi Q8 E-tron Version Dakar.

It’s a automotive that directly could possibly be simply dismissed as an costly folly: just a few will likely be just a few made, it prices some £20,000 greater than a daily Q8 E-tron and Audi will cost you one other £8600 for a wrap that appears like its Dakar Rally raider, simply to make sure that you received’t need to be seen in it.

But on the similar time, it feels to me like a related, early and still-rare foray into electrical off-roading, which is a factor that someday must develop into not extraordinary.

And in the best way that, say, the multifaceted Hyundai Ioniq 5 N can change what we anticipate from efficiency automobiles, so an electrical 4×4 may redefine what we anticipate from off-roaders.

It received’t simply try to copy what an internal-combustion 4×4 can do now however rewrite the e book on it.

Jaguar, for instance, by no means pitched the I-Tempo as an off-roader, but on its launch in 2018 it took us not solely to a race observe to pattern how properly it may rotate into corners but additionally up stupidly steep gravel tracks, by riverbeds and extra.

The I-Tempo has a little-publicised wade depth of 500mm, which individuals don’t routinely got down to problem.

However, after all, not needing oxygen for a whole bunch of explosions each minute, the proper electrical automotive may theoretically wade as deep because it wished. Simply pack scuba gear for the occupants.

There’s extra: as Attwood notes, the Version Dakar has no extra underbody cladding than another Q8 E-tron.

Partly that’s as a result of it’s not a severe rock-crawler but additionally partly as a result of EVs have already got heavy armour for his or her batteries and have fewer spinning or delicate ancillaries that want it.

Lastly, and most significantly for going off highway, there’s the facility supply. The way in which an engine delivers its energy is essentially ruled by the best way it’s designed.

As an illustration, huge journey or scrambling bikes have large-capacity, few-cylinder engines as a result of they make good quantities of torque but additionally as a result of the uneven, pulsing energy supply may help a tyre discover higher traction than a smoother torque supply.

An EV can ship torque to wherever it needs, at any time when it needs, fully the way it needs.
