How does Audi’s RS Q e-tron Dakar automotive work?

Properly, there is a query and a half. Brace your mind for this one, as a result of you are going to want it.

its prepared.

You are proper, then. Let’s get began.

At its core, the RS Q e-tron is an electrical automotive. Which is one thing of a blessing for Audi, because it’s solely spent seven years in Components E. So it is protected to say that any kinks in its electrical drivetrains have been ironed out by now.

Not that they actually appear to want a repair – Lucas di Grassi gained the primary Components E race in 2014 for Audi Sport ABT, in spite of everything, and claimed the driving force’s title in 2017. A 12 months later, the crew would safe its first Components E title, and di Grassi would by no means end outdoors the highest three within the championship.

So it is protected to say that the electrical motors on every axle have been battle-tested, even earlier than the RS Q e-tron first headed to the Arabian Desert final 12 months. And contemplating it claimed 4 stage wins in its first race and has been very dependable this 12 months, we might say it is battle-proven too.

Electrical? They are not standard within the vary, are they?

However. The RS Q e-tron has a 52kWh battery. So, even with a full cost, you possibly can see how scything via smooth sand dunes at racing speeds may be fleeting. Fixing this puzzle is the place the third motor is available in.

This third electrical motor works as a generator and it replenishes the battery. So, like virtually any cell generator, there may be an inside combustion engine connected to the enter shaft of the electrical motor. However, in contrast to different mills, this one is connected to the engine from a DTM automotive.

Wait. Did you say DTM?

Sure. The DTM switched to turbocharged four-cylinder engines in 2019, so it is not the long-lasting V8 you may instantly consider. It is a 2.0-litre four-cylinder, mated to a Garrett turbo that may pump out an absurdly low 51 PSI – extra energy than the V8 produced: over 600bhp within the DTM.

Because of the limitations imposed by the Dakar organizers, about half of that is completed on the RS Q e-tron. However Dakar guidelines additionally restrict the quantity of energy going to the wheels to a shade over 350bhp.

So there is a DTM engine, charging the battery, powering a pair of Components E motors. And that automotive is driving the hardest race on the planet?

That is proper. The rule of thumb while you’re out within the wilderness is ‘simplicity’ – including complexity is simply including methods one thing can go improper. And the RS Q e-tron is loaded down the gunwales with the type of engineering that may encourage a profession in artwork, simply so your future mind won’t ever be good.

However in 2022, after a drawing-to-Dakar growth interval of simply 16 months, the three RS Q e-trons do not have a single problem with their drivetrains. The principle problem was, in true Dakar custom, one thing nobody anticipated.

As crew boss Sven Quandt instructed Prime Gear at Dakar 2022, “I assumed we may land this automotive on the moon, the suspension is so robust, and after I noticed the items and the way they bent… nothing but I noticed one thing like this. earlier than.”

And this can be a man who gained the T1 Marathon World Cup as a driver within the late Nineties, had many victories within the Dakar with totally different groups, even himself. So if he says he is by no means seen something prefer it earlier than, he is by no means seen something prefer it earlier than.

Okay, honest play. However, as sturdy as it’s, does all this know-how have sensible advantages?

Operating the engine in its greatest a part of the rev vary (between 4,500 and 6,000rpm) means getting probably the most energy from each liter of gas. So the RS Q e-tron can go the complete race distance with much less gas, which implies a smaller tank, much less reliance on gas vehicles and so forth. And it’s sustainable gas, referred to as reFuels, that can permit the Audi RS Q e-tron to save lots of greater than 60 p.c carbon dioxide within the 2023 Dakar Rally.

What’s it wish to drive?

The electrical powertrain of the RS Q e-tron additionally has advantages when it comes to driving. Immediate-on torque at any pace, and highly effective regenerative braking, means drivers do not must consistently assume and plan the place they should be within the rev vary to make it up a dune, or maintain their pace down the rocky. refuse. Which is considerable within the desert of Saudia Arabia. And once we say ‘robust regenerative braking’, we imply it – as a result of the Dakar limits the quantity of energy the motors can ship, they will really brake more durable than they will speed up.

However that does not imply acceleration is sluggish – it is nonetheless an AWD electrical automotive, choosing up pace in a manner you possibly can solely obtain with electrical motors. With clean surfaces, huge 37-inch wheels, and a couple of.1 tonnes of RS Q e-tron, the progressive prototype will nonetheless drag itself from a standstill to nicely over 60mph in simply over 4 seconds. And that has about 350bhp going to the wheels, too. There may be extra potential whether it is allowed to be uncorked.

What’s the prime pace of the Audi RS Q e-tron?

Dakar programs are more and more about technical sections that check driver and navigator ability reasonably than hammer-down blasts throughout flat deserts, and prime pace is now restricted to 105mph. So the short build-up between the slower sections means the next common pace throughout the stage, though the highest pace is identical because the purely combustion-powered automobiles.

Then there are issues you do not actually take into consideration. As a result of the entrance and rear motors are unbiased energy sources, there is no such thing as a want for switch circumstances, middle differentials or driveshafts operating the size of the automotive. So there may be extra clearance over the terrain, and fewer harm to the underside of the automotive if they’re lowered.
