We are here considering two somewhat similar cars, but we can't deny some of the obvious differences. For a start, they are not even classified under the same segment, with the Mercedes Benz being a large family car and the Audi representing sports car vehicle class. Another thing to take into account here is the wheel drive. The first one makes use of a rear wheel drive system, aiming at people who are enthusiastic about driving, and don't hesitate to push their car to the limit, even if that requires some additional effort in snow or ice, whereas the second one transfers the power and torque to the front axel only, making it perfect for those who use their car mostly to get from A to B, remaining in control during the slipery conditions.

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 same number of safety stars gained in the process. That aside, let's consider some other aspects which affect safety. The first vehicle is a large family car and that gives it a marginal advantage over the sports car competitor, at least that's what statistics show. Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, Mercedes Benz C offers a marginal difference of 1% 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, at least on all of the models level. These are the official statistics, while our visitors describe reliability of Mercedes Benz with an average rating of 4.3, and models under the Audi badge with 4.2 out of 5. Independent research findings rank C as average reliability-wise, and A5 Coupe is more or less at the same level.Above it all, drivers of cars with the same engine as Mercedes Benz C rank it on average as 3.0, while the one under the competitor's bonnet gets 2.5 out of 5.

Audi is undoubtly more agile, reaching 100km/h in 1.3 seconds less than its competitor. In addition to that it accelerates all the way to 240 kilometers per hour, 15km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 5.9 liters of fuel per 100 kilometers (48 mpg), in combined cycle.

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, Mercedes Benz C offers significantly better overall protection, taking the lead here. From there things take a different 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... 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. In any case that's my personal view, built upon all the data available to me. What should decide here though is the way you feel about the two vehicles, and I hope you'll find my guidelines useful in the process. 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.
