Virtual Adviser's™ opinion

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 sports car segment and utilize the same 2-door cabriolet body style and the rear wheel drive system, it all comes up to the specific petrol engine choice they offer. The first one has a Nissan-engineered powertrain under the hood, a 6-cylinder, 24-valves 280hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 147hp engine designed by Opel.

Safety

Unfortunatelly, neither of the two vehicles was submitted to the European New Car Assessment Programme (Euro NCAP) testing. This makes it virtually impossible for me to pick one over the other and I'm generally against buying such cars as the safety should really always come first. Moving further on, let's take a closer look at some additional safety-related facts. Both vehicles belong to the sports car segment, which is generally classifying them somewhere in the middle 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 Japanese car offers a self-explainatory difference of 85% more metal.

Reliability

I don't like generalizing things when it comes to reliability, although it does seem that Nissan does have a slight advantage, at least on all of the models level. These are the results of an independent reasearch, while our visitors describe reliability of Nissan with an average rating of 4.3, and models under the Opel badge with 4.2 out of 5. Unfortunatelly, I don't have enough insight that would allow me to comment in more details on the specific models level. Above it all, drivers of cars with the same engine as the Japanese car rank it on average as 3.0, while the one under the competitor's bonnet gets 4.2 out of 5.

Performance & Fuel economy

Opel is a bit more agile, reaching 100km/h in 0.5 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 217 kilometers per hour, 33km/h less than the other car. When it comes to fuel economy an obvious choice would be the German car, averaging around 8.5 liters of fuel per 100 kilometers (33 mpg), in combined cycle. That's 34% difference compared to the Japanese car!


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, the Japanese car beats the other contender by far, making it the best choice without even considering other things. From there things take a different direction, with Opel offering somewhat better performance, just enough to call it quicker. To make things even better, it consumps less fuel! I believe that, when we take all into account, we have only one winner here - the Opel. 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. I suggest you spend two more minutes in order to find out which car, based on your needs and budget, would be picked by the virtual adviser, among more than 12.000 different ones in our database.
