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.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the same number of safety stars gained in the process. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the micro car segment, which is generally a misfortune safety-wise, but that fact doesn't break the tie between the two cars. On the other hand, taking kerb weight as an important factor into account, Adam offers a potentially life-saving difference of 32% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Smart does have a slight advantage, when all the models are taken into account. These are the official statistics, while our visitors describe reliability of Smart with an average rating of 4.3, 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 ForTwo rank it on average as 3.0 out of 5, exactly the same as the other one.

Opel 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.

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 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 not difficult to say then that if I'd need to make a choice, it would definitely be 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.
