Audi is reviving the A2 name later this year, and reactions to that news will likely split people into two camps. For some, it will bring back memories of a genuinely forward thinking small car. For others, the original A2 is remembered as the model that looked like Audi’s design department had lost an internal argument and been forced to compromise on nearly every principle it held dear, arguably still the ugliest car the brand has ever put into production. What the original lacked in looks, though, it made up for in substance: a lightweight aluminium body developed with an unusually strong focus on low consumption. That same philosophy is exactly what Audi is now trying to bring back with the electric A2 e-tron.
Audi A2 e-tron efficiency sets a new bar for the brand
The new model gets its world premiere in autumn 2026, but Audi has already released a number of the key technical details ahead of launch.
The headline figure is a provisional WLTP consumption of just 12.8 kWh per 100 km for the 140 kW (190 hp) version fitted with the optional efficiency package, a number Audi says makes the A2 e-tron the most energy efficient car the brand has ever built.
Aerodynamics do most of the heavy lifting
A large part of that efficiency comes down to aerodynamics. With the efficiency package fitted, the A2 e-tron achieves a drag coefficient of 0.24. Audi’s engineers worked through a rounded front end, a smoothly sloping roofline, optimised wheel arches, and an active cooling air intake that stays closed whenever the battery and drivetrain don’t need extra cooling. That kind of detail matters most at higher speeds, where aerodynamic drag accounts for a large share of overall energy use.
Depending on version and equipment, Audi quotes a provisional combined WLTP consumption ranging from 12.8 to 15.6 kWh per 100 km.
A new drivetrain cuts energy losses further
Under the skin, the A2 e-tron uses a permanent magnet synchronous motor paired with a new inverter built around silicon carbide semiconductors. Audi has also trimmed losses within the motor and transmission themselves, and says the resulting drivetrain is up to 10 percent more efficient than previous generations.
Audi A2 e-tron battery uses LFP chemistry
The battery carries a gross capacity of 61 kWh and a usable capacity of 58 kWh, built around LFP chemistry. That choice brings a longer service life and makes it less of a concern to regularly charge the car to 100 percent.
Audi is using a cell to pack design, where the battery cells are integrated directly into the pack structure to make better use of the available space.
Audi A2 e-tron vehicle-to-home turns the car into a power source
The A2 e-tron also supports bidirectional charging. Through Vehicle-to-Load, the car can supply power to tools, laptops or other electrical equipment. Vehicle-to-Home goes a step further, letting the car function as a form of energy storage for the house itself.
That second feature requires a compatible charging box and will initially only be available in select markets. Audi has not yet confirmed whether Denmark will be among them.
Audi A2 e-tron preliminary specifications
| Spec | Detail |
|---|---|
| Power (140 kW version) | 140 kW / 190 hp |
| WLTP consumption (with efficiency package) | 12.8 kWh/100 km |
| WLTP consumption range | 12.8 to 15.6 kWh/100 km |
| Drag coefficient (with efficiency package) | 0.24 |
| Motor | Permanent magnet synchronous motor |
| Inverter | Silicon carbide semiconductors |
| Drivetrain efficiency gain | Up to 10% vs previous generation |

Audi has not yet confirmed final range figures or pricing for Denmark. The finished Audi A2 e-tron will be unveiled in autumn 2026, and if Audi can hold real world consumption close to that provisional 12.8 kWh/100 km figure, the new A2 looks set to be considerably more interesting than its predecessor ever was good looking.
