Overview

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 6-cylinder, 24-valves 333hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 325hp engine designed by Opel.

Safety

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), 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 2% more metal.

Reliability

I don't like generalizing things when it comes to reliability, although it does seem that Opel does have a slight advantage, when all the models are taken into account. 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. The same official information place A4 as average reliability-wise, and Insignia 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 4.3, while the one under the competitor's bonnet gets 5.0 out of 5.

Performance & Fuel economy

Audi is undoubtly more agile, reaching 100km/h in 1 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 250 kilometers per hour, exactly the same as the other car does. When it comes to fuel economy an obvious choice would be Audi A4, averaging around 8.1 liters of fuel per 100 kilometers (35 mpg), in combined cycle. That's 31% difference compared to Insignia!

Verdict

Opel 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. 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! All together, there's not much more to say, in this case I wouldn't even consider anything but 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.
