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 electric engine choice they offer. The first one has a Tesla-engineered powertrain under the hood, a IM Electric unit in formation 1 / 1 with 539hp unit, while the other one gets its power and torque from a PMSM Electric unit in formation 1 / 1 with 540hp 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. Still, apart from the official crash test results there are other things we need to be aware of. 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? On the other hand, taking kerb weight as an important factor into account, the German car offers a marginal difference of 9% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Tesla is significantly less fault-prone, when all the models are taken into account. That's the official data, while our visitors describe reliability of Tesla with an average rating of 1.3, and models under the BMW badge with 4.1 out of 5. Independent research findings rank Model X as average reliability-wise, and iX is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as the American car rank it on average as 3.0 out of 5, exactly the same as the other one.

BMW 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, exactly the same as the other car does. When it comes to fuel economy things look pretty much the same for both cars, especially if you take into account all the free charging points provided by the manufacturer and/or the local government's environmental programs. One of the essential things to consider when it comes to this type of vehicles would be range, although here it's more or less the same, orbiting around 480 kilometers on a single charge.

Tesla 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. It all continues in the same direction, with BMW offering somewhat better performance, just enough to call it quicker. The German car offers somewhat better range. No mistake, whatever you decide here, but I'd still go for 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. 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.
