Well, these are two pretty similar cars we have here! It's only details that could potentially make the difference. Considering they both belong to the sports car segment and utilize the same 2-door coupe body style and the rear wheel drive system, it all comes up to the specific petrol engine choice they offer. The first one has a Ford-engineered powertrain under the hood, a 8-cylinder, 32-valves 421hp unit, while the other one gets its power and torque from a 8-cylinder, 32-valves 571hp engine designed by Mercedes Benz.

The fact that the Ford got tested by the European New Car Assessment Programme (Euro NCAP), while the other contender didn't, doesn't actually do much for it, as it's still a lousy 2-star coffin on wheels. Moving further on, let's take a closer look at some additional safety-related facts. Both vehicles belong to the sports car segment, which is generally classifying them somewhere in the middle safety-wise, but it doesn't do much to help us decide between the two. Furthermore, taking kerb weight as an important factor into account, the American car offers a marginal difference of 8% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Ford as a brand displays somewhat better results, all the models observed together. These are the results of an independent reasearch, while our visitors describe reliability of Ford with an average rating of 4.4, and models under the Mercedes Benz badge with 4.3 out of 5. The same official information place Mustang as average reliability-wise, and SLS is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as the American car rank it on average as 5.0 out of 5, exactly the same as the other one.

Mercedes Benz is undoubtly more agile, reaching 100km/h in 1 seconds less than its competitor. In addition to that it accelerates all the way to 317 kilometers per hour, 67km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 13.4 liters of fuel per 100 kilometers (21 mpg), in combined cycle.

Ford 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, the American car offers slightly better overall protection and takes the lead. From there things take a different direction, with Mercedes Benz outracing its opponent in any situation possible, making it better choice for boy racers. To make things even better, it consumps less fuel! All together, there's not much more to say, in this case I wouldn't even consider anything but 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. In case you have two minutes to spare I invite you to define your needs, desires and budget and see which car would be chosen by the virtual adviser™, among thousands of similar, yet so different vehicles.
