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 'Luxury car' segment, the only major difference here really is their wheel drive configuration (rear for the Mercedes Benz and front in the case of the Rover). 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 6-cylinder, 24-valves 177hp engine designed by Rover.

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 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 luxury car 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 marginal difference of 2% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that Rover as a brand displays somewhat better results, at least on all of the models level. These are the results of an independent reasearch, while our visitors describe reliability of Mercedes Benz with an average rating of 4.4, and models under the Rover badge with 4.5 out of 5. Independent research findings rank E as average reliability-wise, and 75 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 5.0 out of 5.

Rover is a bit more agile, reaching 100km/h in 0.3 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 215 kilometers per hour, 9km/h less than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 10.7 liters of fuel per 100 kilometers (27 mpg), in combined cycle.

Rover 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 Rover offering somewhat better performance, just enough to call it quicker. 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 Rover. 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.
