2018 Mercedes-Benz A-Class vs. 2018 Audi A3

The 2018 Mercedes-Benz A-Class is a nimble yet luxurious sedan. It comes with all the luxury and modern tech that you have come to expect from Mercedes-Benz but in a compact yet elegant package. The 2018 model is stronger, lighter and has enough legroom for the tallest of passengers.

The Audi A3 hasn’t changed much over the years and the 2018 model is no exception. The A3 is in its third generation now and this sub-compact car now features Xenon headlights with high-pressure washes, 17” alloy wheels, and electric seats.

Design & Style

When it comes to design, the Mercedes-Benz A-Class offers an elegant and refined look housed in a compact package. Its alloy wheels match smoothly with the detail shaping on the lower end of the A-Class which serves to reduce drag and enhance performance. The A-Class stands out in any parking lot in its understated styling.

The Audi A3’s styling hasn’t changed dramatically although a few things have been touched up. For example, buyers now get LED headlights as well as LED taillights. The wide grille, with the distinctive Audi rings, is still there although the grille is slightly bigger and more pronounced than in the earlier versions.

Technology & Safety

The Mercedes-Benz A-Class stands out with its array of features including adaptive cruise control, automatic emergency braking as well as lane assist among many other features. You can also connect your phone to your car through Bluetooth®, Android Auto or AppleCare Play. Regardless of what you use, all the connections are fast and responsive.

The Audi A3 comes with fairly decent safety and technology features including a 4G LTE hotspot for WIFI connections. Although a suite of features is available such as lane assist and adaptive cruise control although most are options and not standard features.


The Mercedes-Benz A-Class is fast, thanks to its 2.0-liter engine. Those looking for something more economical can opt for the 1.3-liter version although it does not quite pack the punch that the 2-liter engine does. All said you won’t feel much difference between the two as both variants are still nimble and powerful.

The Audi A3 comes with a 2.0-liter engine that has two variants. One displacing 220 horsepower while the other displaces 186 horsepower. Regardless of the variant, the engines guarantee decent power at the tip of your fingertips. The Audi comes with a seven-speed dual-clutch automatic transmission.

The Bottom Line

Although the Audi A3 is a strong competitor, the Mercedes-Benz A-class still tops the Audi A3 with its powerful and responsive engine as well as its array of technology and safety suits that come as standard.
