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 3-door hatchback body style within the same 'City car' segment, the only major difference here really is their wheel drive configuration (rear for the Renault and front in the case of the Opel). The first one has a Renault-engineered powertrain under the hood, a 6-cylinder, 24-valves 254hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 125hp engine designed by Opel.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), 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 city car segment, which is generally not a very good thing safety-wise, but that fact doesn't break the tie between the two cars. Furthermore, when it comes to weight, a factor that most people underestimate, the French car offers a potentially life-saving difference of 36% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Renault does have a slight advantage, all the models observed together. That's the official data, while our visitors describe reliability of Renault, as well as Opel, with the same average rating of 4.2 out of 5. The same official information place Clio as average reliability-wise, and Corsa is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as the French car rank it on average as 4.0, while the one under the competitor's bonnet gets 4.7 out of 5.

Renault is way more agile, reaching 100km/h in 3.2 seconds less than its competitor. In addition to that it accelerates all the way to 245 kilometers per hour, 43km/h more than the other car. When it comes to fuel economy an obvious choice would be the German car, averaging around 7.7 liters of fuel per 100 kilometers (37 mpg), in combined cycle. That's 55% difference compared to the French car!

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, the French car offers much better overall protection, which launches it ahead of the other contender. It all continues in the same direction, with Renault outracing its opponent in any situation possible, making it better choice for boy racers. It does come at a cost though, and that's the fuel consumption... I believe that, when we take all into account, we have only one winner here - the Renault. 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.
