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 5-door hatchback body style within the same 'City car' segment, the only major difference here really is their wheel drive configuration (front for the Audi and rear in the case of the Smart). The first one has a Volkswagen-engineered powertrain under the hood, a 4-cylinder, 16-valves 140hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 70hp engine designed by Renault.

The 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 Audi being a slightly better choice apparently. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the city car segment, which is generally not a very good thing safety-wise, still it doesn't help us solve our dilemma, does it? Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, Audi A1 offers a considerable difference of 27% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Smart as a brand displays somewhat better results, all the models observed together. These are the official statistics, while our visitors describe reliability of Audi with an average rating of 4.2, 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. Above it all, drivers of cars with the same engine as Audi A1 rank it on average as 3.8, while the one under the competitor's bonnet gets 3.0 out of 5.

Audi is way more agile, reaching 100km/h in 8.9 seconds less than its competitor. In addition to that it accelerates all the way to 212 kilometers per hour, 61km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 4.5 liters of fuel per 100 kilometers (63 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, Audi A1 beats the other contender by far, making it the best choice without even considering other things. It all continues in the same direction, with Audi 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 Audi. 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.
