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 2-door cabriolet body style within the same 'Sports car' segment, the only major difference here really is their wheel drive configuration (front for the Audi and rear in the case of the BMW). The first one has a Audi-engineered powertrain under the hood, a 4-cylinder, 20-valves 163hp unit, while the other one gets its power and torque from a 4-cylinder, 8-valves 115hp engine designed by BMW.

The fact that the Audi got tested by the European New Car Assessment Programme (Euro NCAP), while the other contender didn't, offers a slight advantage, as the 4-star rating is better than none. Moving further on, let's take a closer look at some additional safety-related facts. Both vehicles belong to the sports car segment, which is generally classifying them somewhere in the middle 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 TT offers a considerable difference of 15% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that both brands display similar results in faults and breakdowns, at least on all of the models level. These are the results of an independent reasearch, while our visitors describe reliability of Audi, as well as BMW, with the same average rating of 4.2 out of 5. The same official information place TT as average reliability-wise, and Z3 is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as Audi TT rank it on average as 3.7, while the one under the competitor's bonnet gets 3.0 out of 5.

Audi is undoubtly more agile, reaching 100km/h in 2.3 seconds less than its competitor. In addition to that it accelerates all the way to 218 kilometers per hour, 24km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 8 liters of fuel per 100 kilometers (35 mpg), in combined cycle.

Audi 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 TT 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 being considerably quicker, thus putting more smile on driver's face. 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. 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.
