The launch of the all-new e-tron Quattro is just the first on a long line of upcoming electrics from Audi. The automaker has already promised that there is a slew of all-electric models coming.

"We plan to offer more than 20 electrified models by 2025 – some will be plug-in-hybrids – more than half will be fully-electric," acting Audi CEO Bram Schot said at the reveal of the e-tron.

Word is that "more than half" means a dozen EVs in all key markets and over nearly every segment.

So which ones will be arriving next? After the e-tron will be the e-tron Sportback. That one's coming next year. We've already seen a concept version of the e-tron Sportback. The sleek second EV looks like a beefed-up version of the current A5 and A7 Sportback models. Like a Sportback Allroad.

Audi will be bringing electrification to more segments. After the Sportback will be a compact model in 2020 and a four-door Gran Turismo will arrive that same year. Joining the electric fray will be a new e-tron GT that Schot said "will be the sporty spearhead of our electrified cars."

What does all this mean for the brand? It believes that by the middle of the next decade, one-third of the cars it sells will be electrified.

Helping boost those sales will be the Electrify America charging network in the U.S. In Europe, the e-tron Charging Service will give access to more than 72,000 public charge points including the high-power Ionity network. And in China, "customers will benefit from a strong charging network."
