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 executive car segment and utilize the same 5-door hatchback 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 Mercedes Benz-engineered powertrain under the hood, a PMSM Electric unit in formation 1 / 1 with 449hp unit, while the other one gets its power and torque from a IM Electric unit in formation 1 / 1 with 423hp engine designed by Tesla.

A starting point here would be to take a look at the results from European New Car Assessment Programme (Euro NCAP) tests which were performed on both of the cars, 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 executive car segment, which is generally a fortune safety-wise, still it doesn't help us solve our dilemma, does it? Furthermore, taking kerb weight as an important factor into account, the German car offers a considerable difference of 19% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Tesla is significantly less fault-prone, all the models observed together. These are the official statistics, while our visitors describe reliability of Mercedes Benz with an average rating of 4.4, and models under the Tesla badge with out of 5. Unfortunatelly, I don't have enough insight that would allow me to comment in more details on the specific models level. That apart, owners of different cars powered by the same engine as the German car rank it on average as 3.0 out of 5, exactly the same as the other one.

Tesla is a bit more agile, reaching 100km/h in 0.4 seconds less than its competitor. In addition to that it accelerates all the way to 250 kilometers per hour, 40km/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 560 kilometers on a single charge.

Mercedes Benz 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 significantly better overall protection, taking the lead here. From there things take a different direction, with Tesla offering somewhat better performance, just enough to call it quicker. The American car offers somewhat better range. It's really tough to make a final decision here, but if I'd need to, I'd say Mercedes Benz. Anyway, that's the most objective conclusion I could've came up with and it's based solely on the information found on this website. Aspects such as design, practicality, brand value and driving experience are there for you to measure them out. In case you have two minutes to spare I invite you to define your needs, desires and budget and see which car would be chosen by the virtual adviser™, among thousands of similar, yet so different vehicles.
