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 suv segment and utilize the same 3-door suv body style and the 4 x 4 wheel drive system, it all comes up to the specific diesel engine choice they offer. The first one has a Mercedes Benz-engineered powertrain under the hood, a 8-cylinder, 32-valves 250hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 115hp engine designed by Opel.

Safety

The fact that the Opel got tested by the European New Car Assessment Programme (Euro NCAP), while the other contender didn't, isn't really an advantage, taken the poor 3-star rating it received. Moving further on, let's take a closer look at some additional safety-related facts. Both vehicles belong to the suv segment, which is generally a very good thing safety-wise, still it doesn't help us solve our dilemma, does it? Furthermore, taking kerb weight as an important factor into account, Mercedes Benz G offers a potentially life-saving difference of 34% more metal.

Reliability

I don't like generalizing things when it comes to reliability, although it does seem that Opel does have a slight advantage, at least on all of the models level. These are the official statistics, while our visitors describe reliability of Mercedes Benz with an average rating of 4.4, 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. That apart, owners of different cars powered by the same engine as Mercedes Benz G rank it on average as 4.0, while the one under the competitor's bonnet gets 4.8 out of 5.

Performance & Fuel economy

Mercedes Benz is way more agile, reaching 100km/h in 3.6 seconds less than its competitor. In addition to that it accelerates all the way to 180 kilometers per hour, 25km/h more than the other car. When it comes to fuel economy an obvious choice would be Frontera, averaging around 9.1 liters of fuel per 100 kilometers (31 mpg), in combined cycle. That's 41% difference compared to Mercedes Benz G!


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, Mercedes Benz G offers slightly better overall protection and takes the lead. It all continues in the same direction, with Mercedes Benz outracing its opponent in any situation possible, making it better choice for boy racers. 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 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. Also, you could use the oportunity to find out which car, everything taken into account, would be the perfect choice for you in the eyes of the virtual adviser, among more than 12.000 different ones in our database.
