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 (front for the Renault and rear in the case of the Smart). The first one has a Renault-engineered powertrain under the hood, a 4-cylinder, 8-valves 86hp unit, while the other one gets its power and torque from a 3-cylinder, 12-valves 54hp engine designed by Mercedes Benz.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the same number of safety stars gained in the process. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the micro car segment, which is generally a misfortune 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, the French car offers a considerable difference of 24% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that both brands display similar results in faults and breakdowns, at least on all of the models level. These are the official statistics, while our visitors describe reliability of Renault with an average rating of 4.2, and models under the Smart badge with 4.3 out of 5. Independent research findings rank Twingo as average reliability-wise, and ForTwo is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as the French car rank it on average as 4.3, while the one under the competitor's bonnet gets 3.0 out of 5.

Renault is way more agile, reaching 100km/h in 5.6 seconds less than its competitor. In addition to that it accelerates all the way to 185 kilometers per hour, 50km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 3.5 liters of fuel per 100 kilometers (82 mpg), in combined cycle.

Renault 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 French car offers significantly better overall protection, taking the lead here. It all continues in the same direction, with Renault 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 Renault. 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.
