Two significantly similar cars, no doubt about that. Still, each one has something different to offer. Having both cars powered by diesel engines and utilizing the 4-door sedan 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 Ford and front in the case of the Audi). The first one has a Peugeot-engineered powertrain under the hood, a 4-cylinder, 16-valves 150hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 150hp engine designed by Volkswagen.

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. 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. Furthermore, taking kerb weight as an important factor into account, the American car offers a marginal difference of 5% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Ford as a brand displays somewhat better results, all the models observed together. That's the official data, while our visitors describe reliability of Ford with an average rating of 4.4, and models under the Audi badge with 4.2 out of 5. Some independent research have also placed Mondeo as average reliability-wise, and A4 is more or less at the same level.That apart, owners of different cars powered by the same engine as the American car rank it on average as 4.6 out of 5, exactly the same as the other one.

Audi is undoubtly more agile, reaching 100km/h in 1.4 seconds less than its competitor. In addition to that it accelerates all the way to 220 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 4.5 liters of fuel per 100 kilometers (63 mpg), in combined cycle.

Ford 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 American car 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! No mistake, whatever you decide here, but I'd still go for 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.
