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 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 IM Electric unit in formation 0 / 1 with 315hp unit, while the other one gets its power and torque from a PMSM Electric unit in formation 0 / 1 with 333hp engine designed by Mercedes Benz.

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 executive car segment, which is generally a fortune safety-wise, but that fact doesn't break the tie between the two cars. On the other hand, taking kerb weight as an important factor into account, the German car offers a considerable difference of 24% 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 Tesla with an average rating of 1.3, and models under the Mercedes Benz badge with 4.3 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 American 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 225 kilometers per hour, 15km/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, with throne undoubtedly being claimed by the German car with its additional 151 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 significantly better overall protection, taking the lead here. From there things take a different direction, with Tesla outracing its opponent in any situation possible, making it better choice for boy racers. The German car is incomparably more generous when it comes to range, which could (and potentially should) be a deal-breaker for the other contender. All together, there's not much more to say, in this case I wouldn't even consider anything but 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. 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.
