Audi just declared war on energy waste — and it looks like it's winning without burning a single extra kilowatt. The company has revealed the first detailed specs of its compact electric A2 e-tron, set to premiere this fall 2026. The 140 kW (roughly 190 hp) version with the optional efficiency package posted a preliminary WLTP consumption of 12.8 kWh per 100 km. Audi is calling it the most efficient car it has ever built. Final certification, however, isn't finished yet.
The secret isn't just the battery. A big chunk of that result comes down to aerodynamics. The drag coefficient sits at 0.24 — the best among Audi's compact models. Active air intake shutters, a nearly sealed underbody, special wheels and wheel-arch elements together shave up to 0.9 kWh/100 km off consumption compared with the same car without these tricks. Small details? Maybe. But they add up.
The A2 e-tron runs a permanent-magnet synchronous motor, silicon-carbide power electronics and a gearbox with a 10.2:1 ratio. Audi says the upgraded drivetrain is up to 10% more efficient. And the focus here isn't peak power — it's cutting losses during ordinary city and highway driving, the everyday scenario that actually matters.
Then there's the battery. The LFP pack has a capacity of 61 kWh, with 58 kWh usable. On a fast charger, it accepts up to 105 kW and goes from 10 to 80% in 26 minutes. Audi also says drivers can regularly charge to 100%: the more stable LFP chemistry is meant to age more slowly, though only real-world use by production cars will confirm that.
The EV can also power external devices and feed energy back into the home. The Vehicle-to-Home function will launch first in Germany, Austria and Switzerland, and will require an Audi-recommended charging station.
Orders are expected to open after the fall premiere, with first deliveries promised before the end of 2026. Price and official range, though, are still under wraps — and without them, there's no way to judge how appealing that record-low consumption really is. Watch this space.
Audi previously confirmed the return of hybrid models to the US market.
