Two significantly similar cars, no doubt about that. Still, each one has something different to offer. Having both cars powered by petrol engines and utilizing the 5-door wagon body style within the same 'Large family car' segment, the only major difference here really is their wheel drive configuration (4 x 4 for the Volkswagen and front in the case of the Audi). Both the engines are Volkswagen-engineered . The first one has a 5-cylinder, 20-valves 170hp unit, while the other one gets its power and torque from a 6-cylinder, 30-valves 170hp one.

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 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 large family car segment, which is generally a good thing safety-wise, but it doesn't do much to help us decide between the two. Furthermore, when it comes to weight, a factor that most people underestimate, Passat offers a marginal difference of 5% 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 official statistics, while our visitors describe reliability of Volkswagen, as well as Audi, with the same average rating of 4.2 out of 5. The same official information place Passat as average reliability-wise, and A4 is more or less at the same level.Above it all, drivers of cars with the same engine as Passat rank it on average as 5.0 out of 5, exactly the same as the other one.

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 223 kilometers per hour, 6km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 9.8 liters of fuel per 100 kilometers (29 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 offering somewhat better performance, just enough to call it quicker. To make things even better, it consumps less fuel! No mistake, whatever you decide here, but I'd still go for the Audi. 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.
