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. Moving further on, let's take a closer look at some additional safety-related facts. 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. On the other hand, if we'd like to consider vehicle mass in this context too, which we definitely should, A5 Coupe offers a marginal difference of 8% more metal.

Manufacturers 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. That's the official data, 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. Some independent research have also placed C as average reliability-wise, and A5 Coupe is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as Mercedes Benz C rank it on average as 4.8, while the one under the competitor's bonnet gets 3.7 out of 5.

Mercedes Benz is undoubtly more agile, reaching 100km/h in 1.6 seconds less than its competitor. In addition to that it accelerates all the way to 247 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 4.8 liters of fuel per 100 kilometers (59 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 this case though, it seems that both cars show similar levels of passenger protection all together, so that won't break a tie. But one thing that actually could is the performance, with Mercedes Benz 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... I believe that, when we take all into account, we have only one winner here - the Mercedes Benz. Nevertheless, let's not forget that people have different preferences and needs, so what really counts is your personal feel. I'm only here to help.
