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 4-cylinder, 16-valves 317hp 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, still it doesn't help us solve our dilemma, does it? Furthermore, when it comes to weight, a factor that most people underestimate, the American car offers a marginal difference of 4% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Ford as a brand displays somewhat better results, all the models observed together. These are the official statistics, 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.Above it all, drivers of cars with the same engine as the American car rank it on average as 3.0, while the one under the competitor's bonnet gets 5.0 out of 5.

Mercedes Benz is undoubtly more agile, reaching 100km/h in 2 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 an obvious choice would be the American car, averaging around 8 liters of fuel per 100 kilometers (35 mpg), in combined cycle. That's 65% difference compared to the German car!

Mercedes Benz 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. It does come at a cost though, and that's the fuel consumption... No mistake, whatever you decide here, but I'd still go for the Ford. 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.
