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 2-door cabriolet body style within the same 'Micro car' segment, the only major difference here really is their wheel drive configuration (front for the Mini and rear in the case of the Smart). The first one has a Peugeot-engineered powertrain under the hood, a 4-cylinder, 16-valves 110hp unit, while the other one gets its power and torque from a 3-cylinder, 12-valves 54hp engine designed by Mercedes Benz.

A starting point here would be to take a look at the results from European New Car Assessment Programme (Euro NCAP) tests which were performed on both of the cars, with the Mini being a slightly better choice apparently. 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. Furthermore, taking kerb weight as an important factor into account, the British car offers a potentially life-saving difference of 47% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Smart does have a slight advantage, at least on all of the models level. That's the official data, while our visitors describe reliability of Mini with an average rating of 4.1, and models under the Smart badge with 3.9 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 the British car rank it on average as 4.4, while the one under the competitor's bonnet gets 3.0 out of 5.

Mini is way more agile, reaching 100km/h in 6.5 seconds less than its competitor. In addition to that it accelerates all the way to 194 kilometers per hour, 59km/h more than the other car. When it comes to fuel economy the winner has to be the German car, averaging around 3.3 liters of fuel per 100 kilometers (86 mpg), in combined cycle. We can't ignore that 21% difference compared to the British car.

Mini 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, the British car beats the other contender by far, making it the best choice without even considering other things. It all continues in the same direction, with Mini 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... All together, there's not much more to say, in this case I wouldn't even consider anything but Mini. 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. In case you have two minutes to spare I invite you to define your needs, desires and budget and see which car would be chosen by the virtual adviser™, among thousands of similar, yet so different vehicles.
