It’s hard to not at least like the Audi RS e-tron GT. It’s a 600-ish horsepower, all-electric super sedan with supermodel looks. What’s not to like? Well, actually, the range isn’t great. Despite having a big, whopping 93.4 kWh battery pack, the Audi RS e-tron GT has an EPA-rated range of 232 miles. That’s not bad but it’s not great, either. It essentially means you’re on a 115-mile leash unless you can find a fast-charger. However, according to Edmunds, the RS e-tron GT is actually quite bit more long-legged than the EPA claims.
Edmunds tests all electric vehicles on the same real-world test loop, which takes the electric car from full to flat over the course of many hours. In the case of the Audi RS e-tron GT, Edmunds drove for eight hours and traveled a total of 285 miles. That’s 53 miles more than the EPA-rated range, or a 22 percent increase. Not bad, Audi. Not bad.
The test car used was wearing the larger (heavier) 21″ wheel option but that was offset by the lighter carbon ceramic brakes. Tire pressures were set to the manufacturer’s recommendation, so there was no funny business there. Admittedly, test conditions were ideal, at 79 degrees and dry. Using the heat or air conditioning extensively could drastically reduce the range achieved.
However, there’s a bit of an oddity with the RS e-tron GT’s Edmunds-tested range. The Porsche Taycan 4S (equivalent to the standard e-tron GT), which uses the same battery, achieved 120 miles more than the EPA-rated range. According to the EPA, the Taycan is only capable of 203 miles and yet Edmunds saw 323 miles. That’s not only a massive difference between from the EPA’s numbers but it’s almost 40 more miles than the RS e-tron GT.
Interestingly, the standard Audi e-tron GT only achieved 35 miles more than the EPA-rated figure. So, despite having more power, the Audi RS e-tron GT was more efficient during Edmunds’ time with it than its less powerful sibling.
So if you’re looking at an Audi RS e-tron GT — or even the standard e-tron GT or Porsche Taycan — but are concerned with its claimed range, understand that any of those cars will likely beat the EPA-rated figures by a decent margin.
