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 front 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 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. Still, apart from the official crash test results there are other things we need to be aware of. 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, taking kerb weight as an important factor into account, Audi A4 offers a marginal difference of 1% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Volkswagen does have a slight advantage, when all the models are taken into account. These are the results of an independent reasearch, 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 0.3 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 226 kilometers per hour, 2km/h less than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 9.5 liters of fuel per 100 kilometers (30 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, Audi A4 offers slightly better overall protection and takes the lead. It all continues in the same direction, with Audi offering somewhat better performance, just enough to call it quicker. It does come at a cost though, and that's the fuel consumption... At the end, as much as I'd like to give you a winner here, it's simply a pure tie if you ask me. In any case that's my personal view, built upon all the data available to me. What should decide here though is the way you feel about the two vehicles, and I hope you'll find my guidelines useful in the process.
