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 2-door cabriolet body style within the same 'Sports car' segment, the only major difference here really is their wheel drive configuration (front for the Opel and rear in the case of the Smart). The first one has a Opel-engineered powertrain under the hood, a 4-cylinder, 16-valves 125hp unit, while the other one gets its power and torque from a 3-cylinder, 6-valves 100hp engine designed by Smart.

The fact that the Opel got tested by the European New Car Assessment Programme (Euro NCAP), while the other contender didn't, offers a slight advantage, as the 4-star rating is better than none. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the sports 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, if we'd like to consider vehicle mass in this context too, which we definitely should, Tigra offers a potentially life-saving difference of 40% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning 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 Opel with an average rating of 4.2, and models under the Smart badge with 4.3 out of 5. Independent research findings rank Tigra as average reliability-wise, and Roadster is more or less at the same level.That apart, owners of different cars powered by the same engine as Tigra rank it on average as 4.7, while the one under the competitor's bonnet gets 3.0 out of 5.

Opel is a bit more agile, reaching 100km/h in 0.4 seconds less than its competitor. In addition to that it accelerates all the way to 204 kilometers per hour, 14km/h more than the other car. When it comes to fuel economy an obvious choice would be Roadster, averaging around 5.3 liters of fuel per 100 kilometers (53 mpg), in combined cycle. That's 45% difference compared to Tigra!

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, Tigra beats the other contender by far, making it the best choice without even considering other things. 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. Nevertheless, let's not forget that people have different preferences and needs, so what really counts is your personal feel. I'm only here to help.
