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 5-door wagon body style within the same 'Luxury car' segment, the only major difference here really is their wheel drive configuration (front for the Audi and 4 x 4 in the case of the Mercedes Benz). The first one has a Volkswagen-engineered powertrain under the hood, a 6-cylinder, 30-valves 193hp unit, while the other one gets its power and torque from a 6-cylinder, 18-valves 204hp engine designed by Mercedes Benz.

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 Mercedes Benz being a slightly better choice apparently. 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, 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, Mercedes Benz E offers a considerable difference of 15% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that both brands display similar results in faults and breakdowns, all the models observed together. That's the official data, while our visitors describe reliability of Audi with an average rating of 4.2, and models under the Mercedes Benz badge with 4.4 out of 5. The same official information place A6 as average reliability-wise, and E is more or less at the same level.That apart, owners of different cars powered by the same engine as Audi A6 rank it on average as 4.9, while the one under the competitor's bonnet gets 3.0 out of 5.

Audi is undoubtly more agile, reaching 100km/h in 1.8 seconds less than its competitor. In addition to that it accelerates all the way to 234 kilometers per hour, 17km/h more than the other car. When it comes to fuel economy the winner has to be Audi A6, averaging around 9.9 liters of fuel per 100 kilometers (29 mpg), in combined cycle. We can't ignore that 16% difference compared to Mercedes Benz E.

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 beats the other contender by far, making it the best choice without even considering other things. From there things take a different direction, with Audi being considerably quicker, thus putting more smile on driver's face. To make things even better, it consumps less fuel! I believe that, when we take all into account, we have only one winner here - the 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. Also, you could use the oportunity to find out which car, everything taken into account, would be the perfect choice for you in the eyes of the virtual adviser™, among thousands of similar, yet so different vehicles.
