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, if we'd like to consider vehicle mass in this context too, which we definitely should, 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, when all the models are taken into account. That's the official data, while our visitors describe reliability of Ford, as well as Mercedes Benz, with the same average rating of 4.4 out of 5. Some independent research have also placed 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 being considerably quicker, thus putting more smile on driver's face. To make things even better, it consumps less fuel! No mistake, whatever you decide here, but I'd still go for the 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.
