Virtual Adviser's™ opinion

Overview

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 (front for the Audi and rear in the case of the Mercedes Benz). The first one has a Volkswagen-engineered powertrain under the hood, a 6-cylinder, 24-valves 190hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 190hp engine designed by Mercedes Benz.

Safety

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), 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 it doesn't do much to help us decide between the two. Furthermore, taking kerb weight as an important factor into account, Audi A6 offers a marginal difference of 1% more metal.

Reliability

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, 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 Mercedes Benz badge with 4.4 out of 5. Some independent research have also placed A6 as average reliability-wise, and E is more or less at the same level.Above it all, drivers of cars with the same engine as Audi A6 rank it on average as 4.2, while the one under the competitor's bonnet gets 4.4 out of 5.

Performance & Fuel economy

Audi is a bit more agile, reaching 100km/h in 0.7 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 232 kilometers per hour, 9km/h less than the other car. When it comes to fuel economy the winner has to be Audi A6, averaging around 6.2 liters of fuel per 100 kilometers (46 mpg), in combined cycle. We can't ignore that 11% difference compared to Mercedes Benz E.


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 slightly better overall protection and takes the lead. It all continues in the same direction, with Audi offering somewhat better performance, just enough to call it quicker. To make things even better, it consumps less fuel! All together, there's not much more to say, in this case I wouldn't even consider anything but 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. In case you have two minutes to spare I invite you to define your needs, desires and budget and see which car would be chosen by the virtual adviser, among more than 12.000 different ones in our database.
