Virtual Adviser's™ opinion
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 6-cylinder, 24-valves 224hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 115hp engine designed by Opel.
SafetyThe 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, but it doesn't do much to help us decide between the two. Furthermore, taking kerb weight as an important factor into account, Mercedes Benz G offers a considerable difference of 28% more metal.
ReliabilityReliability is not the best thing to consider on the make level, but it is worth mentioning that Opel does have a slight advantage, when all the models are taken into account. These are the results of an independent reasearch, 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. Above it all, drivers of cars with the same engine as Mercedes Benz G rank it on average as 4.5, while the one under the competitor's bonnet gets 3.9 out of 5.
Performance & Fuel economyMercedes Benz is way more agile, reaching 100km/h in 5.1 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 the winner has to be Frontera, averaging around 9.1 liters of fuel per 100 kilometers (31 mpg), in combined cycle. We can't ignore that 21% difference compared to Mercedes Benz G.
Verdict
Mercedes Benz 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 this case though, it seems that both cars show similar levels of passenger protection all together, so that won't break a tie. But one thing that actually could is the performance, 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... It's really tough to make a final decision here, but if I'd need to, I'd say 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 thousands of similar, yet so different vehicles.
