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 Volkswagen-engineered powertrain under the hood, a 12-cylinder, 48-valves 450hp unit, while the other one gets its power and torque from a 8-cylinder, 32-valves 360hp engine designed by BMW.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), 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 suv segment, which is generally a very good thing safety-wise, still it doesn't help us solve our dilemma, does it? Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, Touareg offers a marginal difference of 5% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Volkswagen does have a slight advantage, at least on all of the models level. That's the official data, while our visitors describe reliability of Volkswagen, as well as BMW, with the same average rating of 4.2 out of 5. Independent research findings rank Touareg as average reliability-wise, and X5 is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as Touareg rank it on average as 3.0, while the one under the competitor's bonnet gets 4.0 out of 5.

Volkswagen is a bit more agile, reaching 100km/h in 0.2 seconds less than its competitor. In addition to that it accelerates all the way to 250 kilometers per hour, 4km/h more than the other car. When it comes to fuel economy an obvious choice would be BMW X5, averaging around 13.5 liters of fuel per 100 kilometers (21 mpg), in combined cycle. That's 18% difference compared to Touareg!

BMW 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, Touareg offers slightly better overall protection and takes the lead. It all continues in the same direction, with Volkswagen offering somewhat better performance, just enough to call it quicker. It does come at a cost though, and that's the fuel consumption... All together, there's not much more to say, in this case I wouldn't even consider anything but 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. 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.
