Virtual Adviser's™ opinion
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 'Micro car' segment, the only major difference here really is their wheel drive configuration (rear for the Smart and front in the case of the Opel). The first one has a Renault-engineered powertrain under the hood, a 4-cylinder, 16-valves 70hp unit, while the other one gets its power and torque from a 3-cylinder, 12-valves 90hp engine designed by General Motors.
SafetyThe 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 micro car segment, which is generally a misfortune safety-wise, but it doesn't do much to help us decide between the two. On the other hand, when it comes to weight, a factor that most people underestimate, Adam offers a potentially life-saving difference of 32% more metal.
ReliabilityManufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Smart does have a slight advantage, all the models observed together. That's the official data, while our visitors describe reliability of Smart with an average rating of 3.9, 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. We should definitely mention that owners of cars with the same powertrain as ForTwo rank it on average as 3.0 out of 5, exactly the same as the other one.
Performance & Fuel economyOpel is undoubtly more agile, reaching 100km/h in 2.5 seconds less than its competitor. In addition to that it accelerates all the way to 180 kilometers per hour, 29km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 4.2 liters of fuel per 100 kilometers (68 mpg), in combined cycle.
Verdict
Smart 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, Adam offers much better overall protection, which launches it ahead of the other contender. It all continues in the same direction, with Opel 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 Opel. Anyway, that's the most objective conclusion I could've came up with and it's based solely on the information found on this website. Aspects such as design, practicality, brand value and driving experience are there for you to measure them out.
