As the marketplace—and technology—for electric vehicles continues to mature, high-end luxury brands have entered the space with some truly compelling products. Audi, no stranger to innovation, offers a host of electrified models under the “e-tron” banner. (And before one asks, yes, it is supposed to be all lowercase.) Much like Audi’s famed “quattro” moniker (also all-lowercase per Audi’s rules), the e-tron name is used to denote both the lineup of electrified offerings, and is also the dedicated name of two specific Audi models: the e-tron crossover and the e-tron GT.
