Audi has revealed its “considerably improved” RS Q e-tron E2 off-road racer prototype, which wears reworked physique panels for better aerodynamic efficiency.
It’s an evolution of the earlier Audi RS Q e-tron revealed in July 2021, which scored 4 stage victories on the 2022 Dakar rally in January.
The E2 naming conference used on this prototype has beforehand been used on the second technology of Audi’s Quattro Group B rally automobiles within the Eighties.
“The Audi RS Q e-tron E2 doesn’t undertake a single physique half from its predecessor,” stated RS Q e-tron chief designer Axel Löffler.
A spotlight of the outside physique modifications embody alterations to the entrance and rear fascias, which now taper inwards and resemble the form of a ship’s hull.
The big wheel arches have additionally been revised to save lots of weight and to optimise air move.
To be able to adjust to prescribed inside dimensions, the cockpit within the Audi RS Q e-tron E2 is now wider than earlier than.
Audi has lowered the prototype’s centre of gravity and claims to have lowered the general aerodynamic drag by 15 per cent by doing computational fluid dynamics (CFD) that simulate testing in a wind tunnel.
“The aerodynamic side shouldn’t be underestimated in desert rallying both,” stated Mr Löffler.
Though Audi doesn’t point out a precise weight for the RS Q e-tron E2, laws stipulate a minimal weight of 2100kg.
The off-road racer prototype has a “simplified operation” which, for example, permits crews to vary tyres within the occasion of a puncture extra successfully.
There are actually detachable physique panels as a substitute of the earlier cumbersome covers on the flanks of the prototype.
Audi additionally notes the brand new 10-spoke Rotiform rims are “a lot simpler to deal with”.
Though there have been quite a few modifications to the RS Q e-tron E2’s physique, its electrical range-extender powertrain is retained.
The Audi RS Q e-tron E2 has electrical motors nicked from the Audi Components E automotive on each axles, backed by a 3rd motor-generator unit performing as an inverter which feeds regenerated power into the 52kWh lithium-ion battery pack.
Supporting the 52kWh battery pack is a 2.0-litre turbocharged four-cylinder petrol engine from Audi’s present DTM automotive.
Relatively than powering the wheels straight, it runs at between 4500 and 6000rpm to feed the battery pack.
Complete system output on this newest prototype is round 288kW of energy, however we already know that it’s able to 500kW.
Drive is shipped by a single-speed racing transmission.
There’s additionally a software-based digital centre differential, in addition to bodily limited-slip differentials on every axle.
Audi claims the RS Q e-tron E2 can do the 0-100km/h dash on a unfastened floor in lower than 4.5 seconds, and high pace is proscribed to 170km/h.
The Audi RS Q e-tron will make its rallying debut on the Rally du Maroc in Morocco, which can run from October 1 to six, earlier than competing on the 2023 Dakar Rally.
