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 150hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 136hp engine designed by Opel.

The first thing to look into here would be the results from European New Car Assessment Programme (Euro NCAP) tests performed on the two cars. Good thing is that both vehicles got tested, with the same number of safety stars gained in the process. 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. On the other hand, if we'd like to consider vehicle mass in this context too, which we definitely should, the German car offers a marginal difference of 4% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Toyota does have a slight advantage, when all the models are taken into account. 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.Above it all, drivers of cars with the same engine as the Japanese car rank it on average as 4.6, while the one under the competitor's bonnet gets 5.0 out of 5.

Toyota is a bit more agile, reaching 100km/h in 0.9 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 210 kilometers per hour, 5km/h less than the other car. When it comes to fuel economy the winner has to be the Japanese car, averaging around 7.7 liters of fuel per 100 kilometers (37 mpg), in combined cycle. We can't ignore that 12% difference compared to the German car.

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 German car offers slightly better overall protection and takes the lead. From there things take a different direction, with Toyota offering somewhat better performance, just enough to call it quicker. To make things even better, it consumps less fuel! All together, there's not much more to say, in this case I wouldn't even consider anything but Toyota. In any case that's my personal view, built upon all the data available to me. What should decide here though is the way you feel about the two vehicles, and I hope you'll find my guidelines useful in the process.
