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 diesel engines and utilizing the 4-door sedan body style within the same 'Luxury car' segment, the only major difference here really is their wheel drive configuration (rear for the Mercedes Benz and 4 x 4 in the case of the Audi). The first one has a Mercedes Benz-engineered powertrain under the hood, a 6-cylinder, 24-valves 231hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 245hp engine designed by Audi.
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 luxury car segment, which is generally a very 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, Mercedes Benz E offers a marginal difference of 3% more metal.
ReliabilityManufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that both brands display similar results in faults and breakdowns, all the models observed together. These are the official statistics, while our visitors describe reliability of Mercedes Benz with an average rating of 4.4, and models under the Audi badge with 4.2 out of 5. Some independent research have also placed E as average reliability-wise, and A6 is more or less at the same level.That apart, owners of different cars powered by the same engine as Mercedes Benz E rank it on average as 4.2, while the one under the competitor's bonnet gets 4.7 out of 5.
Performance & Fuel economyAudi is undoubtly more agile, reaching 100km/h in 1.4 seconds less than its competitor. In addition to that it accelerates all the way to 250 kilometers per hour, 8km/h more than the other car. When it comes to fuel economy the winner has to be Mercedes Benz E, averaging around 4.2 liters of fuel per 100 kilometers (67 mpg), in combined cycle. We can't ignore that 43% difference compared to Audi A6.
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, Mercedes Benz E offers slightly better overall protection and takes the lead. From there things take a different 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... I believe that, when we take all into account, we have only one winner here - the Mercedes Benz. 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.
