Overview

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 (rear for the Smart and front in the case of the Audi). The first one has a Nissan-engineered powertrain under the hood, a 3-cylinder, 12-valves 109hp unit, while the other one gets its power and torque from a 4-cylinder, 8-valves 86hp engine designed by Volkswagen.

Safety

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 Audi 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 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, taking kerb weight as an important factor into account, ForFour offers a marginal difference of 5% more metal.

Reliability

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Smart as a brand displays somewhat better results, at least on all of the models level. These are the results of an independent reasearch, while our visitors describe reliability of Smart with an average rating of 4.3, and models under the Audi 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. We should definitely mention that owners of cars with the same powertrain as ForFour rank it on average as 3.0, while the one under the competitor's bonnet gets 3.9 out of 5.

Performance & Fuel economy

Smart is undoubtly more agile, reaching 100km/h in 1.4 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 180 kilometers per hour, exactly the same as the other car does. When it comes to fuel economy things look pretty much the same for both cars, averaging around 4.9 liters of fuel per 100 kilometers (58 mpg), in combined cycle.

Verdict

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 offers slightly better overall protection and takes the lead. From there things take a different direction, with Smart being considerably quicker, thus putting more smile on driver's face. To make things even better, it consumps less fuel! I believe that, when we take all into account, we have only one winner here - the Smart. 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.
