Virtual Adviser's™ opinion
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 luxury car segment and utilize the same 5-door wagon body style and the 4 x 4 wheel drive system, it all comes up to the specific petrol engine choice they offer. The first one has a Mercedes Benz-engineered powertrain under the hood, a 6-cylinder, 24-valves 252hp unit, while the other one gets its power and torque from a 8-cylinder, 32-valves 420hp engine designed by Volkswagen.
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. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the luxury car segment, which is generally a very good thing safety-wise, but that fact doesn't break the tie between the two cars. On the other hand, if we'd like to consider vehicle mass in this context too, which we definitely should, Audi A6 offers a considerable difference of 10% 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. The same official information place E as average reliability-wise, and A6 is more or less at the same level.Above it all, drivers of cars with the same engine as Mercedes Benz E rank it on average as 3.0 out of 5, exactly the same as the other one.
Performance & Fuel economyAudi is way more agile, reaching 100km/h in 3.1 seconds less than its competitor. In addition to that it accelerates all the way to 250 kilometers per hour, 7km/h more than the other car. When it comes to fuel economy the winner has to be Mercedes Benz E, averaging around 7.8 liters of fuel per 100 kilometers (36 mpg), in combined cycle. We can't ignore that 24% difference compared to Audi A6.
Verdict
Mercedes Benz 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, Audi A6 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... It's really tough to make a final decision here, but if I'd need to, I'd say 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.
