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. The first one has a Volkswagen-engineered powertrain under the hood, a 4-cylinder, 16-valves 180hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 220hp engine designed by Opel.

A starting point here would be to take a look at the results from European New Car Assessment Programme (Euro NCAP) tests which were performed on both of the cars, 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 that fact doesn't break the tie between the two cars. On the other hand, taking kerb weight as an important factor into account, Insignia offers a marginal difference of 6% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Opel does have a slight advantage, all the models observed together. These are the official statistics, while our visitors describe reliability of Audi, as well as Opel, with the same average rating of 4.2 out of 5. Some independent research have also placed A4 as average reliability-wise, and Insignia is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as Audi A4 rank it on average as 5.0, while the one under the competitor's bonnet gets 4.3 out of 5.

Both of the cars accelerate exactly the same, so we couldn't put one above the other. Car No. 2 is faster though, reaching top speed of 240 kilometers per hour, 8km/h more than the other car. When it comes to fuel economy an obvious choice would be Audi A4, averaging around 6.8 liters of fuel per 100 kilometers (42 mpg), in combined cycle. That's 31% difference compared to Insignia!

Audi 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, Insignia offers slightly better overall protection and takes the lead. It all continues in the same direction, with Opel offering somewhat better performance, just enough to call it quicker. It does come at a cost though, and that's the fuel consumption... It's not difficult to say then that if I'd need to make a choice, it would definitely be 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.
