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 4 x 4 wheel drive system, aiming at people who plan to leave their safety zone and challenge the surfface, both in the terms of reduced grip and offroading, 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.

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 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. On the other hand, when it comes to weight, a factor that most people underestimate, A5 Coupe 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, all the models observed together. That's the official data, 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. Some independent research have also placed A5 Coupe as average reliability-wise, and C is more or less at the same level.Above it all, drivers of cars with the same engine as A5 Coupe rank it on average as 5.0, while the one under the competitor's bonnet gets 3.0 out of 5.

Audi is a bit more agile, reaching 100km/h in 0.2 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 250 kilometers per hour, exactly the same as the other car does. When it comes to fuel economy things look pretty much the same for both cars, averaging around 6.6 liters of fuel per 100 kilometers (43 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 offering somewhat better performance, just enough to call it quicker. To make things even better, it consumps less fuel! It's not difficult to say then that if I'd need to make a choice, it would definitely be the 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.
