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 front wheel drive system, it all comes up to the specific petrol engine choice they offer. The first one has a Toyota-engineered powertrain under the hood, a 4-cylinder, 16-valves 160hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 155hp engine designed by Opel.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the Toyota being a slightly better choice apparently. Moving further on, let's take a closer look at some additional safety-related facts. 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, when it comes to weight, a factor that most people underestimate, the Japanese car offers a marginal difference of 1% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that Toyota does have a slight advantage, at least on all of the models level. These are the official statistics, while our visitors describe reliability of Toyota with an average rating of 4.6, and models under the Opel badge with 4.2 out of 5. The same official information place Avensis as average reliability-wise, and Vectra is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as the Japanese car rank it on average as 5.0, while the one under the competitor's bonnet gets 3.0 out of 5.

Toyota is a bit more agile, reaching 100km/h in 0.5 seconds less than its competitor. In addition to that it accelerates all the way to 220 kilometers per hour, 2km/h more than the other car. When it comes to fuel economy the winner has to be the German car, averaging around 7.7 liters of fuel per 100 kilometers (37 mpg), in combined cycle. We can't ignore that 23% difference compared to the Japanese car.

Toyota is apparently more reliable, not too much, but just enough. 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 offers much better overall protection, which launches it ahead of the other contender. It all continues in the same direction, with Toyota 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 Toyota. 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.
