New specifics regarding the E-Tron's estimated range have just been posted up by AutoGuide. Under the CARB cycle, this electric SUV should provide drivers with around 277 miles on a full charge. Earlier estimates directly from Audi suggested 249 miles under the WLTP, so we will have to wait on real world numbers to see which is more accurate. Keep in mind that top speed is different under each of these tests. In comparison the MB EQC has been set at 200+ miles and the I-Pace claims 234 miles on a single charge.
