Two significantly similar cars, no doubt about that. Still, each one has something different to offer. Having both cars powered by petrol engines and utilizing the 4-door sedan body style within the same 'Large family car' segment, the only major difference here really is their wheel drive configuration (4 x 4 for the Audi and front in the case of the Mazda). The first one has a Volkswagen-engineered powertrain under the hood, a 6-cylinder, 24-valves 333hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 170hp engine designed by Mazda.

A starting point here would be to take a look at the results from European New Car Assessment Programme (Euro NCAP) tests which were performed on both of the cars, with the same number of safety stars gained in the process. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the large family car segment, which is generally a good thing safety-wise, but that fact doesn't break the tie between the two cars. Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, the German car offers a considerable difference of 27% 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, at least on all of the models level. These are the official statistics, 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. Some independent research have also placed A4 as average reliability-wise, and 6 is more or less at the same level.That apart, owners of different cars powered by the same engine as the German car rank it on average as 4.3, while the one under the competitor's bonnet gets 5.0 out of 5.

Audi is undoubtly more agile, reaching 100km/h in 2.9 seconds less than its competitor. In addition to that it accelerates all the way to 250 kilometers per hour, 30km/h more than the other car. When it comes to fuel economy the winner has to be the Japanese car, averaging around 8.1 liters of fuel per 100 kilometers (35 mpg), in combined cycle. We can't ignore that 20% difference compared to the German car.

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 significantly better overall protection, taking the lead here. It all continues in the same direction, with Audi outracing its opponent in any situation possible, making it better choice for boy racers. 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. Nevertheless, let's not forget that people have different preferences and needs, so what really counts is your personal feel. I'm only here to help.
