Virtual Adviser's™ opinion
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 cabriolet 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 Nissan-engineered powertrain under the hood, a 6-cylinder, 24-valves 320hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 306hp engine designed by Mercedes Benz.
SafetyUnfortunatelly, neither of the two vehicles was submitted to the European New Car Assessment Programme (Euro NCAP) testing. This makes it virtually impossible for me to pick one over the other and I'm generally against buying such cars as the safety should really always come first. 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?
ReliabilityI don't like generalizing things when it comes to reliability, although it does seem that Infiniti does have a slight advantage, at least on all of the models level. That's the official data, while our visitors describe reliability of Infiniti with an average rating of 4.5, and models under the Mercedes Benz badge with 4.4 out of 5. Some independent research have also placed Q60 as average reliability-wise, and SL is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as the Japanese car rank it on average as 5.0 out of 5, exactly the same as the other one.
Performance & Fuel economyMercedes Benz 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 250 kilometers per hour, exactly the same as the other car does. When it comes to fuel economy an obvious choice would be the German car, averaging around 6.8 liters of fuel per 100 kilometers (42 mpg), in combined cycle. That's 68% difference compared to the Japanese car!
Verdict
Infiniti 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 Mercedes Benz offering somewhat better performance, just enough to call it quicker. 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. 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.
