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 BMW and front in the case of the Rover). The first one has a BMW-engineered powertrain under the hood, a 6-cylinder, 24-valves 218hp 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. Still, apart from the official crash test results there are other things we need to be aware of. Both vehicles belong to the luxury car segment, which is generally a very good thing safety-wise, but it doesn't do much to help us decide between the two. On the other hand, if we'd like to consider vehicle mass in this context too, which we definitely should, the British car offers a marginal difference of 4% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Rover as a brand displays somewhat better results, when all the models are taken into account. These are the results of an independent reasearch, while our visitors describe reliability of BMW with an average rating of 4.2, and models under the Rover badge with 4.5 out of 5. Independent research findings rank 5 Series 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 3.8, while the one under the competitor's bonnet gets 5.0 out of 5.

BMW is undoubtly more agile, reaching 100km/h in 2 seconds less than its competitor. In addition to that it accelerates all the way to 245 kilometers per hour, 30km/h more than the other car. When it comes to fuel economy the winner has to be the German car, averaging around 8.7 liters of fuel per 100 kilometers (32 mpg), in combined cycle. We can't ignore that 21% difference compared to the British car.

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 British car offers slightly better overall protection and takes the lead. From there things take a different direction, with BMW being considerably quicker, thus putting more smile on driver's face. To make things even better, it consumps less fuel! It's not difficult to say then that if I'd need to make a choice, it would definitely be the BMW. 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.
