Well, these are two pretty similar cars we have here! It's only details that could potentially make the difference. Considering they both belong to the large family car segment and utilize the same 4-door sedan body style and the front wheel drive system, it all comes up to the specific petrol engine choice they offer. The first one has a Volkswagen-engineered powertrain under the hood, a 4-cylinder, 20-valves 130hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 145hp engine designed by Mazda.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the same number of safety stars gained in the process. Moving further on, let's take a closer look at some additional safety-related facts. Both vehicles belong to the large family car segment, which is generally a good thing safety-wise, but it doesn't do much to help us decide between the two. Furthermore, taking kerb weight as an important factor into account, the German car offers a marginal difference of 3% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that Mazda as a brand displays somewhat better results, when all the models are taken into account. These are the results of an independent reasearch, while our visitors describe reliability of Audi with an average rating of 4.2, and models under the Mazda badge with 4.4 out of 5. Independent research findings rank A4 as average reliability-wise, and 6 is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as the German car rank it on average as 4.9, while the one under the competitor's bonnet gets 4.2 out of 5.

Mazda is a bit more agile, reaching 100km/h in 0.2 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 208 kilometers per hour, 4km/h less than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 8.2 liters of fuel per 100 kilometers (34 mpg), in combined cycle.

Mazda appears just a bit more reliable, although the difference is truly marginal. The most important thing when deciding between any two vehicles should always be safety, both passive and active. In my opinion, everything taken into account, the German car offers slightly better overall protection and takes the lead. From there things take a different direction, with Mazda offering somewhat better performance, just enough to call it quicker. It does come at a cost though, and that's the fuel consumption... No mistake, whatever you decide here, but I'd still go for the Audi. Anyway, that's the most objective conclusion I could've came up with and it's based solely on the information found on this website. Aspects such as design, practicality, brand value and driving experience are there for you to measure them out.
