Two significantly similar cars, no doubt about that. Still, each one has something different to offer. Having both cars powered by electric engines and utilizing the 5-door hatchback body style within the same 'Large family car' segment, the only major difference here really is their wheel drive configuration (4 x 4 for the Tesla and rear in the case of the BMW). The first one has a Tesla-engineered powertrain under the hood, a PMSM Electric unit in formation 1 / 1 with 346hp unit, while the other one gets its power and torque from a IM Electric unit in formation 0 / 1 with 340hp engine designed by BMW.

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 Tesla being a slightly better choice apparently. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the large family car segment, which is generally a good thing safety-wise, but it doesn't do much to help us decide between the two. On the other hand, when it comes to weight, a factor that most people underestimate, the German car offers a considerable difference of 15% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that Tesla is significantly less fault-prone, at least on all of the models level. These are the official statistics, 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 3 as average reliability-wise, and i4 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.

Tesla is undoubtly more agile, reaching 100km/h in 1.3 seconds less than its competitor. In addition to that it accelerates all the way to 233 kilometers per hour, 43km/h more than the other car. 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 570 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 this case though, it seems that both cars show similar levels of passenger protection all together, so that won't break a tie. But one thing that actually could is the performance, with Tesla outracing its opponent in any situation possible, making it better choice for boy racers. The German car offers somewhat better range. All together, there's not much more to say, in this case I wouldn't even consider anything but Tesla.
