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 5-door wagon 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.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the same number of safety stars gained in the process. Moving further on, let's take a closer look at some additional safety-related facts. Both vehicles belong to the luxury car segment, which is generally a very good thing safety-wise, still it doesn't help us solve our dilemma, does it? Furthermore, when it comes to weight, a factor that most people underestimate, the German car offers a marginal difference of 4% 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, all the models observed together. These are the official statistics, while our visitors describe reliability of Mercedes Benz with an average rating of 4.3, 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.We should definitely mention that owners of cars with the same powertrain 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 0.5 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 206 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 10.9 liters of fuel per 100 kilometers (26 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. When it comes to performance, both vehicles provide similar experience, so I wouldn't point any of them out. the British car still consumps less fuel, which needs to be taken into consideration. No mistake, whatever you decide here, but I'd still go for 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.
