Audi a3 allstreet vs. mercedes a 250 e: a plug-in hybrid showdown
The contenders: a quick overview
The automotive landscape is buzzing with plug-in hybrid options, and two frontrunners have emerged: the Audi A3 allstreet TFSI e and the Mercedes A 250 e. While the A3 is a relatively new addition to Audi’s portfolio, the A 250 e has been around since 2018. Both vehicles were showcased at the IAA Frankfurt Motor Show, and offer a compelling blend of gasoline and electric power, though their approaches differ significantly. This review breaks down the key differences to help you decide which is the better choice.
nn
Performance and powertrain
The Mercedes A 250 e boasts a combined system output of 218 horsepower and 450 Nm of torque, derived from a 163 hp four-cylinder engine and a 109 hp electric motor. This allows for a swift 0-100 km/h sprint in just 7.3 seconds, with ample power for overtaking. The top speed reaches 225 km/h. The Audi A3 allstreet, in comparison, produces a combined 204 hp, with a 150 hp four-cylinder engine and an 116 hp electric motor. It manages the 0-100 km/h dash in 7.4 seconds, a marginal difference, but it excels in how it delivers that power.
nn
Driving dynamics and handling
While the Mercedes A 250 e offers a comfortable ride, particularly over uneven surfaces, the Audi A3 allstreet demonstrates a more agile and controlled driving experience. The A3’s higher center of gravity is noticeable on undulating roads, resulting in more pronounced body roll. However, it delivers power to the front wheels with greater dexterity, minimizing wheelspin compared to the Mercedes’ tendency to “scrabble” for traction on the asphalt. Both models are electronically limited to a top speed of 225 km/h.
nn
Battery range and charging
Here’s where the differences become more significant. The Audi A3 allstreet features a 19.7 kWh battery, providing a claimed electric range of up to 132 kilometers. In real-world testing at 5 degrees Celsius, it managed 89 kilometers. The Mercedes A 250 e has a smaller 13 kWh battery, offering a shorter claimed range of 79 kilometers, and a real-world range of only 65 kilometers. The Audi also benefits from a larger fuel tank, holding five liters more than the Mercedes.
nn
Charging times and infrastructure
The Audi A3 allstreet features a standard 40 kW charger, allowing for a 10-80% charge in just 26 minutes at a compatible charging station. Mercedes, on the other hand, comes standard with a 3.7 kW charger, extending the charging time to 4.5 hours. However, for an additional 500 euros, you can upgrade to a 22 kW charger, significantly reducing charging time to around half an hour. This highlights a key difference in charging capabilities and overall convenience.
nn
Interior and technology
The Mercedes A 250 e’s interior boasts a higher-quality feel, with meticulously crafted materials and a visually appealing design. The centerpiece is its generously sized infotainment screen and the acclaimed MBUX system, which has been praised for its intuitive operation and extensive functionality. The Audi’s interior, while well-finished, doesn't quite match the Mercedes in terms of material quality. The A3’s 12.3-inch display is only available as part of the navigation package, and while the “Hey Audi” voice command system is functional, it can be slightly delayed.

Final verdict
Both the Audi A3 allstreet TFSI e and the Mercedes A 250 e offer compelling plug-in hybrid experiences. AUTO BILD awarded the Audi a score of 8.2, praising its modern design, improved charging technology, and longer range. The Mercedes A 250 e received a score of 8, commended for its longevity, although criticized for its shorter electric range and smaller fuel tank. Ultimately, the Audi A3 allstreet emerges as the slightly more well-rounded package, offering a more modern feel and better overall practicality.
