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 hatchback 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 Opel and front in the case of the Renault). The first one has a Opel-engineered powertrain under the hood, a 4-cylinder, 16-valves 220hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 205hp engine designed by Renault.

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. Furthermore, taking kerb weight as an important factor into account, the German car offers a considerable difference of 13% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Renault does have a slight advantage, all the models observed together. These are the results of an independent reasearch, while our visitors describe reliability of Opel with an average rating of 4.2, and models under the Renault badge with 4.1 out of 5. The same official information place Insignia as average reliability-wise, and Laguna is more or less at the same level.Above it all, drivers of cars with the same engine as the German car rank it on average as 4.7, while the one under the competitor's bonnet gets 4.8 out of 5.

Opel is a bit more agile, reaching 100km/h in 0.1 seconds less than its competitor. In addition to that it accelerates all the way to 240 kilometers per hour, 8km/h more than the other car. When it comes to fuel economy the winner has to be the French car, averaging around 8.2 liters of fuel per 100 kilometers (34 mpg), in combined cycle. We can't ignore that 9% difference compared to the German car.

Renault 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 German car offers significantly better overall protection, taking the lead here. 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... No mistake, whatever you decide here, but I'd still go for the Renault. 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.
