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 'Large family car' segment, the only major difference here really is their wheel drive configuration (rear for the Mercedes Benz and 4 x 4 in the case of the Volvo). The first one has a Mercedes Benz-engineered powertrain under the hood, a 6-cylinder, 18-valves 170hp unit, while the other one gets its power and torque from a 5-cylinder, 20-valves 213hp engine designed by Volvo.

The first thing to look into here would be the results from European New Car Assessment Programme (Euro NCAP) tests performed on the two cars. Good thing is that both vehicles got tested, with the Mercedes Benz being a slightly better choice apparently. Moving further on, let's take a closer look at some additional safety-related facts. Both vehicles belong to the large family car segment, which is generally a good thing safety-wise, still it doesn't help us solve our dilemma, does it? On the other hand, when it comes to weight, a factor that most people underestimate, the Swedish car offers a marginal difference of 6% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Volvo does have a slight advantage, when all the models are taken into account. That's the official data, while our visitors describe reliability of Mercedes Benz with an average rating of 4.4, and models under the Volvo badge with 4.6 out of 5. Some independent research have also placed C as average reliability-wise, and S60 is more or less at the same level.That apart, owners of different cars powered by the same engine as the German car rank it on average as 4.7, while the one under the competitor's bonnet gets 4.6 out of 5.

Volvo is undoubtly more agile, reaching 100km/h in 1.9 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 225 kilometers per hour, 10km/h less than the other car. When it comes to fuel economy the winner has to be the Swedish car, averaging around 9.7 liters of fuel per 100 kilometers (29 mpg), in combined cycle. We can't ignore that 10% difference compared to the German car.

Volvo 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 slightly better overall protection and takes the lead. From there things take a different direction, with Volvo being considerably quicker, thus putting more smile on driver's face. 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 Volvo. 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.
