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 large family car segment and utilize the same 5-door hatchback body style and the rear 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 PMSM Electric unit in formation 0 / 1 with 261hp unit, while the other one gets its power and torque from a IM Electric unit in formation 0 / 1 with 286hp 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. Still, apart from the official crash test results there are other things we need to be aware of. Both vehicles belong to the large family car segment, which is generally a good thing safety-wise, still it doesn't help us solve our dilemma, does it? On the other hand, when it comes to weight, a factor that most people underestimate, the German car offers a considerable difference of 22% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Tesla is significantly less fault-prone, when all the models are taken into account. These are the results of an independent reasearch, 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. Some independent research have also placed Model 3 as average reliability-wise, and i4 is more or less at the same level.Above it all, drivers of cars with the same engine as the American car rank it on average as 3.0, while the one under the competitor's bonnet gets 1.0 out of 5.

Tesla is a bit more agile, reaching 100km/h in 0.9 seconds less than its competitor. In addition to that it accelerates all the way to 225 kilometers per hour, 35km/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, giving a significant advantage to the German car with its additional 65 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 provides significantly better range, something that shouldn't be overlooked. It's really tough to make a final decision here, but if I'd need to, I'd say Tesla. 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.
