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 both the axels, making it perfect for those who plan to leave their safety zone and challenge the surfface, both in the terms of reduced grip and offroading.

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. Still, apart from the official crash test results there are other things we need to be aware of. 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, taking kerb weight as an important factor into account, A5 Coupe offers a marginal difference of 7% 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, when all the models are taken into account. 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. Some independent research have also placed 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 5.0 out of 5.

Audi is undoubtly more agile, reaching 100km/h in 2.6 seconds less than its competitor. In addition to that it accelerates all the way to 250 kilometers per hour, 35km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 6.5 liters of fuel per 100 kilometers (44 mpg), in combined cycle.

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 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 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 not difficult to say then that if I'd need to make a choice, it would definitely be the Audi. 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.
