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 suv segment and utilize the same 5-door suv body style and the 4 x 4 wheel drive system, it all comes up to the specific petrol engine choice they offer. The first one has a Toyota-engineered powertrain under the hood, a 6-cylinder, 24-valves 272hp unit, while the other one gets its power and torque from a 6-cylinder, 18-valves 218hp engine designed by Mercedes Benz.

The fact that the Mercedes Benz got tested by the European New Car Assessment Programme (Euro NCAP), while the other contender didn't, offers a slight advantage, as the 4-star rating is better than none. Still, apart from the official crash test results there are other things we need to be aware of. Both vehicles belong to the suv segment, which is generally a very good thing safety-wise, still it doesn't help us solve our dilemma, does it? On the other hand, taking kerb weight as an important factor into account, the German car offers a considerable difference of 16% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that Lexus as a brand displays somewhat better results, when all the models are taken into account. These are the official statistics, while our visitors describe reliability of Lexus with an average rating of 4.9, and models under the Mercedes Benz badge with 4.3 out of 5. Some independent research have also placed RX as average reliability-wise, and ML is more or less at the same level.That apart, owners of different cars powered by the same engine as the Japanese car rank it on average as 3.0, while the one under the competitor's bonnet gets 4.6 out of 5.

Lexus is undoubtly more agile, reaching 100km/h in 1.2 seconds less than its competitor. In addition to that it accelerates all the way to 200 kilometers per hour, 5km/h more than the other car. When it comes to fuel economy an obvious choice would be the Japanese car, averaging around 11.2 liters of fuel per 100 kilometers (25 mpg), in combined cycle. That's 21% 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 beats the other contender by far, making it the best choice without even considering other things. From there things take a different direction, with Lexus outracing its opponent in any situation possible, making it better choice for boy racers. To make things even better, it consumps less fuel! I believe that, when we take all into account, we have only one winner here - the Lexus. 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. Also, you could use the oportunity to find out which car, everything taken into account, would be the perfect choice for you in the eyes of the virtual adviser™, among thousands of similar, yet so different vehicles.
