Overview

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 Audi being a sports car and the Mercedes Benz representing large family car vehicle class. Another thing to take into account here is the wheel drive. The first one makes use of a front wheel drive system, aiming at people who use their car mostly to get from A to B, remaining in control during the slipery conditions, whereas the second one transfers the power and torque to the rear axel only, making it perfect for those 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.

Safety

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 second 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 3% 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 results of an independent reasearch, while our visitors describe reliability of Audi with an average rating of 4.2, and models under the Mercedes Benz badge with 4.3 out of 5. Independent research findings rank A5 Coupe as average reliability-wise, and C is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as A5 Coupe rank it on average as 2.5, while the one under the competitor's bonnet gets 5.0 out of 5.

Performance & Fuel economy

Audi is a bit more agile, reaching 100km/h in 0.5 seconds less than its competitor. In addition to that it accelerates all the way to 240 kilometers per hour, 3km/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.

Verdict

Mercedes Benz is apparently more reliable, not too much, but just enough. 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 being considerably quicker, thus putting more smile on driver's face. Fuel consumption is more or less the same. It's really tough to make a final decision here, but if I'd need to, I'd say Mercedes Benz. 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.
