However there are nonetheless carbonfibre parts to the RS Q E-tron, in that the battery and motors are mounted on enormous, 20mm-thick carbonfibre plates that slot up into the spaceframe chassis and are protected by alloy/foam sheets. This achieves two issues: it makes the components simple to swap out and it offers extra flexibility to the packaging than you’ll anticipate with a normal tubular chassis. However it does run the chance of issues getting too stiff.
As such, they’re controversial. Quandt was very nervous about them at the beginning of the undertaking. He says: “We linked all of the areas [of the chassis] with carbon plates. This can be a new thought, however I used to be sceptical about them as a result of the chassis strikes and these are inflexible carbon plates. However actually, now I’m very pleased with how they’ve carried out.”
There are single shocks all spherical. A twin- shock set-up was investigated, however the weight was a difficulty (Audi readily acknowledges that the two-tonne-plus automobile must go on a food regimen, however reliability has been prioritised over weight-saving), so singles it was. And in addition to, suspension journey is the true key. “You probably have extra suspension journey, you can be quicker than a automobile with 100bhp extra energy,” claims Quandt.
The full measurement of the RS Q E-tron? 4500mm lengthy, 1950mm excessive and 2300mm extensive, with a 3080mm wheelbase for its wheel-at-each-corner stance. To present you an thought of perspective, that’s a bit bit shorter than the BMW 3 Collection however practically 10cm taller and wider than the Vary Rover.
As ever, the important thing to all this might be reliability. That’s partly why Audi has performed what it has performed: the components are confirmed and, in a programme that has been going for under 12 months, testing and improvement time has been woefully brief.
Software program goes to be the massive headache, as Quandt factors out: “We now have 4 separate programs that need to be taught to speak with one another. It’s been a giant problem.” Certainly, on high of the same old coding complexity, these programs might be continuously pounded by mud and vibration.
Not that the situations have helped the comparatively well-proven engine, both. The temperatures and humidity in Saudi Arabia fluctuate wildly over the course of a day, and this, mixed with the altitude adjustments the automobile will expertise, made working vary a giant problem within the 8500 kilometres of testing that the crew has performed.
