Two significantly similar cars, no doubt about that. Still, each one has something different to offer. Having both cars powered by diesel 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 224hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 177hp 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. Still, apart from the official crash test results there are other things we need to be aware of. Both vehicles belong to the large family car segment, which is generally a good thing safety-wise, but it doesn't do much to help us decide between the two. Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, the German car offers a marginal difference of 3% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Lexus as a brand displays somewhat better results, all the models observed together. 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.We should definitely mention that owners of cars with the same powertrain as the German car rank it on average as 4.5, while the one under the competitor's bonnet gets 4.2 out of 5.

Mercedes Benz is undoubtly more agile, reaching 100km/h in 2.2 seconds less than its competitor. In addition to that it accelerates all the way to 250 kilometers per hour, 30km/h more than the other car. When it comes to fuel economy an obvious choice would be the Japanese car, averaging around 5.6 liters of fuel per 100 kilometers (50 mpg), in combined cycle. That's 38% difference compared to the German car!

Lexus 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. 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... At the end, as much as I'd like to give you a winner here, it's simply a pure tie if you ask me. 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.
