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 diesel engine choice they offer. The first one has a Volkswagen-engineered powertrain under the hood, a 4-cylinder, 8-valves 100hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 121hp engine designed by Mazda.

The first thing to look into here would be the results from European New Car Assessment Programme (Euro NCAP) tests performed on the two cars. Good thing is that both vehicles got tested, 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, still it doesn't help us solve our dilemma, does it? On the other hand, when it comes to weight, a factor that most people underestimate, the Japanese car offers a marginal difference of 3% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears 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.Above it all, drivers of cars with the same engine as the German car rank it on average as 4.4 out of 5, exactly the same as the other one.

Mazda is undoubtly more agile, reaching 100km/h in 1.3 seconds less than its competitor. In addition to that it accelerates all the way to 198 kilometers per hour, 3km/h more than the other car. When it comes to fuel economy the winner has to be the German car, averaging around 5.4 liters of fuel per 100 kilometers (52 mpg), in combined cycle. We can't ignore that 20% difference compared to the Japanese 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 Japanese car offers slightly better overall protection and takes the lead. It all continues in the same direction, with Mazda being considerably quicker, thus putting more smile on driver's face. It does come at a cost though, and that's the fuel consumption... It's really tough to make a final decision here, but if I'd need to, I'd say 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.
