Virtual Adviser's™ opinion
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, 30-valves 220hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 166hp engine designed by Mazda.
SafetyA 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. Still, apart from the official crash test results there are other things we need to be aware of. 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? Furthermore, when it comes to weight, a factor that most people underestimate, the German car offers a considerable difference of 13% more metal.
ReliabilityReliability 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 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. The same official information place 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 5.0, while the one under the competitor's bonnet gets 3.0 out of 5.
Performance & Fuel economyAudi is undoubtly more agile, reaching 100km/h in 2 seconds less than its competitor. In addition to that it accelerates all the way to 243 kilometers per hour, 29km/h more than the other car. When it comes to fuel economy the winner has to be the Japanese car, averaging around 8.9 liters of fuel per 100 kilometers (32 mpg), in combined cycle. We can't ignore that 18% difference compared to the German car.
Verdict
Audi 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 being considerably quicker, thus putting more smile on driver's face. It does come at a cost though, and that's the fuel consumption... At the end, as much as I'd like to give you a winner here, it's simply a pure tie if you ask me. 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.
