Audi has revealed fresh details and camouflaged prototype shots of the upcoming A2 e-tron, confirming that the electric hatchback will be the most efficient production car the brand has ever built. The A2 e-tron is expected to debut in full this fall, with European sales scheduled to begin in the end 2026 to early 2027 timeframe.
Reborn Audi A2 adopts the original's efficiency-first ethos
Achieved 7.81km/kWh WLTP energy efficiency in preliminary testing
Equipped with the optional Efficiency Package, the A2 e-tron recorded a preliminary WLTP energy consumption figure of just 12.8kWh/100km (7.81km/kWh), making it the German carmaker's most energy-efficient model to date. Notably, the original A2 (sold from 1999 to 2005) was built to deliver superb fuel economy, and its EV successor clearly adheres to the same efficiency-first principles.
Audi says the A2 e-tron achieves its impressive claimed efficiency via a combination of advanced aerodynamics, a highly optimised drivetrain, and a battery designed specifically for everyday use. The Efficiency Package lowers the A2 e-tron’s energy consumption by up to 0.9kWh/100km over the standard model.
The A2 e-tron also boasts a drag coefficient of 0.24, the lowest of any compact Audi to date. To achieve this, Audi has equipped the A2 e-tron with a rounded fascia, a flowing roofline, a fully enclosed underbody, air curtains, wheel arch gap reducers, an upright rear end, and an active front cooling intake that remains closed during normal driving to minimise drag. The intake automatically opens during rapid charging, heavy acceleration, or high ambient temperatures to provide additional cooling for the battery and power electronics.
Other observable design highlights on the A2 e-tron prototype include a split-headlamp setup, L-shaped intakes up front, aero-optimised alloy wheels, wide rectangular tail-lamps, subtly flared fenders, and a silhouette that pays homage to the original A2 – the A2 e-tron actually looks quite similar to the Hyundai Ioniq 3 in profile.
Audi A2 e-tron to offer 61kWh battery in base spec
Estimated WLTP range of around 453km
Entry-level versions of the A2 e-tron are confirmed to offer a 61kWh (58kWh usable) LFP battery that powers a rear-mounted 190hp electric motor dubbed APP350. Multiplying the usable battery capacity with the aforementioned 7.81km/kWh efficiency figure yields an indicative WLTP range of 453km.
The A2 e-tron's battery uses a cell-to-pack design that improves packaging efficiency while eliminating conventional battery modules. It can even be routinely charged to 100 percent without the degradation concerns associated with other battery chemistries. A revised thermal management system also improves home wallbox charging efficiency to 89.6 percent.
According to Audi, the A2 e-tron's electric drive system is around 10 percent more efficient than previous designs. Improvements include silicon carbide (SiC) power electronics, thinner motor laminations to reduce energy losses, revised stator windings, and a new low-friction transmission oil paired with a tall 10.2:1 gear ratio for improved highway efficiency.
The A2 e-tron will also support vehicle-to-load (V2L) functionality, allowing owners to power external appliances with up to 2.3kW of output, as well as a vehicle-to-home (V2H) feature that enables the vehicle to act as a home energy storage system when paired with compatible charging equipment.
While Audi has confirmed only the 140kW version of the A2 e-tron for now, more variants are expected to be part of the line-up. Since the A2 e-tron shares its underpinnings with the Volkswagen ID 3 Neo, which gets a 79kWh NMC battery option, the Audi hatchback could offer a similarly sized unit.
