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 diesel engine choice they offer. The first one has a Toyota-engineered powertrain under the hood, a 4-cylinder, 16-valves 177hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 150hp engine designed by FIAT.

A starting point here would be to take a look at the results from European New Car Assessment Programme (Euro NCAP) tests which were performed on both of the cars, with the Toyota being a slightly better choice apparently. 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 it doesn't do much to help us decide between the two. Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, the Japanese car offers a marginal difference of 1% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Toyota does have a slight advantage, when all the models are taken into account. That's the official data, 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.That apart, owners of different cars powered by the same engine as the Japanese car rank it on average as 4.1 out of 5, exactly the same as the other one.

Toyota is undoubtly more agile, reaching 100km/h in 1.2 seconds less than its competitor. In addition to that it accelerates all the way to 220 kilometers per hour, 3km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 6 liters of fuel per 100 kilometers (47 mpg), in combined cycle.

Toyota 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 offers much better overall protection, which launches it ahead of the other contender. It all continues in the same direction, with Toyota being considerably quicker, thus putting more smile on driver's face. 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 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.
