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 4-door sedan body style and the 4 x 4 wheel drive system, it all comes up to the specific petrol engine choice they offer. Both the engines are Volkswagen-engineered . The first one has a 6-cylinder, 30-valves 220hp unit, while the other one gets its power and torque from a 6-cylinder, 30-valves 193hp one.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the same number of safety stars gained in the process. Moving further on, let's take a closer look at some additional safety-related facts. Both vehicles belong to the large family car segment, which is generally a 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, Passat offers a marginal difference of 1% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Volkswagen does have a slight advantage, at least on all of the models level. These are the results of an independent reasearch, while our visitors describe reliability of Audi, as well as Volkswagen, with the same average rating of 4.2 out of 5. Independent research findings rank A4 as average reliability-wise, and Passat is more or less at the same level.That apart, owners of different cars powered by the same engine as Audi A4 rank it on average as 5.0, while the one under the competitor's bonnet gets 4.9 out of 5.

Audi 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 243 kilometers per hour, 5km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 10.6 liters of fuel per 100 kilometers (27 mpg), in combined cycle.

Volkswagen 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, Passat offers slightly better overall protection and takes the lead. From there things take a different direction, with Audi being considerably quicker, thus putting more smile on driver's face. To make things even better, it consumps less fuel! 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. I suggest you spend two more minutes in order to find out which car, based on your needs and budget, would be picked by the virtual adviser™, among thousands of similar, yet so different vehicles.
