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 'Small family car' segment, the only major difference here really is their wheel drive configuration (4 x 4 for the Volkswagen and front in the case of the Opel). The first one has a Volkswagen-engineered powertrain under the hood, a 6-cylinder, 24-valves 250hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 240hp 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 small family 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, Golf offers a considerable difference of 13% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that both brands display similar results in faults and breakdowns, at least on all of the models level. That's the official data, while our visitors describe reliability of Volkswagen, as well as Opel, with the same average rating of 4.2 out of 5. Some independent research have also placed Golf as average reliability-wise, and Astra is more or less at the same level.That apart, owners of different cars powered by the same engine as Golf rank it on average as 4.3, while the one under the competitor's bonnet gets 5.0 out of 5.

Opel is a bit more agile, reaching 100km/h in 0.1 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 244 kilometers per hour, 6km/h less than the other car. When it comes to fuel economy the winner has to be Astra, averaging around 9.2 liters of fuel per 100 kilometers (31 mpg), in combined cycle. We can't ignore that 16% difference compared to Golf.

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, Golf offers significantly better overall protection, taking the lead here. When it comes to performance, both vehicles provide similar experience, so I wouldn't point any of them out. Astra , on the other hand, consumps significantly less fuel, and that's a big plus. No mistake, whatever you decide here, but I'd still go for the Opel. 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.
