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 (4 x 4 for the Mercedes Benz and rear in the case of the Lexus). The first one has a Mercedes Benz-engineered powertrain under the hood, a 6-cylinder, 24-valves 231hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 207hp engine designed by Toyota.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the same number of safety stars gained in the process. That aside, let's consider some other aspects which affect safety. 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 Japanese car offers a marginal difference of 2% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Lexus 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 Mercedes Benz with an average rating of 4.3, and models under the Lexus badge with 4.9 out of 5. Some independent research have also placed C as average reliability-wise, and IS is more or less at the same level.Above it all, drivers of cars with the same engine as the German car rank it on average as 4.0, while the one under the competitor's bonnet gets 5.0 out of 5.

Mercedes 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 247 kilometers per hour, 17km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 9.8 liters of fuel per 100 kilometers (29 mpg), in combined cycle.

Lexus is apparently more reliable, not too much, but just enough. 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 Japanese 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. Fuel consumption is more or less the same. It's really tough to make a final decision here, but if I'd need to, I'd say 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. In case you have two minutes to spare I invite you to define your needs, desires and budget and see which car would be chosen by the virtual adviser™, among thousands of similar, yet so different vehicles.
