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 Volkswagen-engineered powertrain under the hood, a PMSM Electric unit in formation 1 / 1 with 299hp unit, while the other one gets its power and torque from a IM Electric unit in formation 1 / 1 with 286hp 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 suv segment, which is generally a very good thing safety-wise, but that fact doesn't break the tie between the two cars. On the other hand, if we'd like to consider vehicle mass in this context too, which we definitely should, EQC offers a considerable difference of 10% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that both brands display similar results in faults and breakdowns, when all the models are taken into account. These are the results of an independent reasearch, while our visitors describe reliability of Audi with an average rating of 4.2, 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 Q4 e-tron rank it on average as 3.0 out of 5, exactly the same as the other one.

Audi is a bit more agile, reaching 100km/h in 0.7 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 180 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, giving a significant advantage to Q4 e-tron with its additional 52 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, EQC offers significantly better overall protection, taking the lead here. From there things take a different direction, with Audi offering somewhat better performance, just enough to call it quicker. Q4 e-tron provides significantly better range, something that shouldn't be overlooked. I believe that, when we take all into account, we have only one winner here - the Audi. Nevertheless, let's not forget that people have different preferences and needs, so what really counts is your personal feel. I'm only here to help.
