Two significantly similar cars, no doubt about that. Still, each one has something different to offer. Having both cars powered by diesel 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 Seat). The first one has a Smart-engineered powertrain under the hood, a 3-cylinder, 6-valves 41hp unit, while the other one gets its power and torque from a 3-cylinder, 6-valves 75hp engine designed by Volkswagen.

The fact that the Smart 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. Still, apart from the official crash test results there are other things we need to be aware of. 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, taking kerb weight as an important factor into account, the Spanish car offers a considerable difference of 29% more metal.

Manufacturers 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 Seat badge with 4.4 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 the German car rank it on average as 4.5, while the one under the competitor's bonnet gets 4.4 out of 5.

Seat is way more agile, reaching 100km/h in 7.7 seconds less than its competitor. In addition to that it accelerates all the way to 170 kilometers per hour, 35km/h more than the other car. When it comes to fuel economy the winner has to be the German car, averaging around 3.4 liters of fuel per 100 kilometers (83 mpg), in combined cycle. We can't ignore that 26% difference compared to the Spanish car.

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 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 Seat 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 Smart. 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.
