- Audi A2 e-tron will achieve 12.8 kWh per 100 km under WLTP conditions in its 140 kW configuration, making it the brand's most efficient car ever and beating the original A2's famed "three-liter" fuel economy benchmark from over 25 years ago.
- The A2 e-tron posts a drag coefficient of 0.24 — the best in Audi's compact lineup — aided by an active cool-air intake that stays closed during normal driving and at higher speeds.
- The 140 kW version uses a 61 kWh lithium iron phosphate (LFP) battery with 89.6% wallbox charging efficiency, employing a cell-to-pack design to optimize energy density and free interior space.
- Audi equips the entry-level EV with bidirectional charging, enabling Vehicle-to-Load (V2L) and Vehicle-to-Home (V2H) functions so the car can act as a mobile energy bank.
- Pricing starts at approximately €38,200 (~$44,000) in Germany, with a WLTP range of up to 403 miles (649 km) — nearly €10,000 less than the Q4 e-tron's €47,500 starting price.
- The lineup will offer four power outputs (125 kW, 140 kW, 170 kW, and 240 kW) and three battery packs (50 kWh, 58 kWh, and 79 kWh) when it goes on sale this fall.
Why it matters: Audi is pricing its new entry-level EV roughly €10,000 below the Q4 e-tron while delivering the brand's best-ever efficiency at 12.8 kWh/100km, narrowing the gap between premium German EVs and mass-market competitors. The LFP battery choice and cell-to-pack packaging signal Audi is optimizing for cost and longevity over raw energy density, a meaningful strategic shift for a brand long associated with high-spec nickel-based packs.
