Audi just announced some of its eTron R8 specs and detail nuts like me will note some pretty impressive numbers starting at the huge 92kWh battery that has 7kWh more storage than Tesla’s top end option. Tesla has said on numerous occasions that it *could* build a bigger more dense battery in the same space (perhaps as a later upgrade), but hasn’t because of cost constraints.
Also the e-Tron has a Drag coefficient of .28 — .04 higher than the Model S. It should be noted that the e-Tron is a theoretical sports car and the Model S is a 7 seat family sedan that has been on the road for almost 3 years. But Audi clearly is keeping a lot of the petrol edition’s drag-inducing air intakes for the electric edition.
That takes a toll on range with the Audi sports car tallying just under 280 mile range compared to the Model S 85D range of 285 miles. The e-Tron’s speed is also a bit behind Tesla with a reported 3.9 second 0-62 and top speed of 130. That’s almost a full second behind the P85D and 20 mph slower. Torque is also impressive, but still far behind Tesla.
On the other hand it looks like a sports car inside and out which will certainly appeal to some folks.
But for Tesla, this is a win. Audi’s just announced R8 doesn’t beat Tesla’s 3 year old Model S in any relevant space with speed or range and holds 5 fewer passengers.
Relevant from press release below:
Electrified: Audi R8 e-tron The second generation of the Audi R8 forms the basis for two more models. Audi has made major engineering developments in its high-performance electric sports car, the R8 e-tron. The latest evolution of the vehicle takes up the multimaterial Audi Space Frame from the new series-production model.
The supporting structure was enhanced by a CFRP rear-section module comprising the luggage compartment. The walls of the CFRP luggage compartment well are corrugated. This way, in the event of a rear-end collision, more energy can be absorbed despite the reduced material weight.
Thanks to targeted modifications to the outer shell and on the wheels, the Audi R8 e‑tron achieves an aerodynamic drag coefficient (cd) value of 0.28. In terms of performance and range, the car enters entirely new dimensions.
The large T-shaped battery is structurally integrated into the center tunnel and behind the occupant cell – optimally positioned in the car. It supports the dynamics of the R8 e-tron with its low center of gravity. Audi produces the high-voltage battery itself, for the first time based on a newly developed lithium-ion technology which was specially conceived for a purely electric vehicle drive. In comparison to the first technology platform, the battery capacity has grown from 49 kWh to approximately 92 kWh. This progress was possible without changing the package.
The R8 e-tron achieves an electric range of 450 kilometers (279.6 mi) instead of a previous 215 kilometers (133.6 mi) with an energy density that has been increased from 84 Wh/kg to 154 Wh/kg and some other modifications to the car. The electrically powered high-performance sports car has the Combined Charging System (CCS) on board, which allows charging with direct and alternating current. Using this system, it is possible to fully charge the battery in significantly less than two hours.
The power is now twice 170 kW and the maximum torque twice 460 Nm (339.3 lb-ft). The R8 e-tron 2.0 accelerates from 0 to 100 km/h (62.1 mph) in 3.9 seconds on its way to an electronically restricted top speed of 210 km/h (130.5 mph) or 250 km/h (155.3 mph). Intelligent energy management and an electromechanical brake system enable high energy recuperation rates. Targeted torque vectoring – needs-based distribution of power transmission between the rear wheels – ensures maximum stability and dynamism.
Audi uses the electrical high-performance sports car primarily as a mobile high-tech laboratory. Accordingly, the findings from the R8 e-tron help in creating a vehicle with a sedan character. Upon customer request, the R8 e-tron will be available for order in 2015 as an electrically powered sports car in supreme hand-built quality.
