Virtual Adviser's™ opinion
Two significantly similar cars, no doubt about that. Still, each one has something different to offer. Having both cars powered by petrol engines and utilizing the 4-door sedan body style within the same 'Luxury car' segment, the only major difference here really is their wheel drive configuration (front for the Volvo and rear in the case of the Mercedes Benz). The first one has a Mazda-engineered powertrain under the hood, a 4-cylinder, 16-valves 145hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 272hp 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. Still, apart from the official crash test results there are other things we need to be aware of. Both vehicles belong to the luxury car segment, which is generally a very good thing safety-wise, but that fact doesn't break the tie between the two cars. On the other hand, if we'd like to consider vehicle mass in this context too, which we definitely should, the German car offers a considerable difference of 15% more metal.
ReliabilityI don't like generalizing things when it comes to reliability, although it does seem that Volvo does have a slight advantage, all the models observed together. These are the results of an independent reasearch, while our visitors describe reliability of Volvo with an average rating of 4.6, and models under the Mercedes Benz badge with 4.4 out of 5. The same official information place S80 as average reliability-wise, and CLS is more or less at the same level.Above it all, drivers of cars with the same engine as the Swedish car rank it on average as 4.2, while the one under the competitor's bonnet gets 5.0 out of 5.
Performance & Fuel economyMercedes Benz is way more agile, reaching 100km/h in 3.9 seconds less than its competitor. In addition to that it accelerates all the way to 250 kilometers per hour, 45km/h more than the other car. When it comes to fuel economy the winner has to be the Swedish car, averaging around 8.3 liters of fuel per 100 kilometers (34 mpg), in combined cycle. We can't ignore that 22% difference compared to the German car.
Verdict
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 German car offers significantly better overall protection, taking the lead here. It all continues in the same 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... It's really tough to make a final decision here, but if I'd need to, I'd say 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.
