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 Mercedes Benz-engineered powertrain under the hood, a 6-cylinder, 18-valves 245hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 272hp engine designed by Toyota.

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. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the suv segment, which is generally a very good thing safety-wise, but that fact doesn't break the tie between the two cars. Furthermore, 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.

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. These are the official statistics, while our visitors describe reliability of Mercedes Benz with an average rating of 4.4, and models under the Lexus badge with 4.9 out of 5. The same official information place ML as average reliability-wise, and RX 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 3.8, while the one under the competitor's bonnet gets 3.0 out of 5.

Lexus is a bit more agile, reaching 100km/h in 0.9 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 200 kilometers per hour, 5km/h less 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 26% 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 offering somewhat better performance, just enough to call it quicker. To make things even better, it consumps less fuel! It's really tough to make a final decision here, but if I'd need to, I'd say 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.
