Overview

Well, these are two pretty similar cars we have here! It's only details that could potentially make the difference. Considering they both belong to the sports car segment and utilize the same 2-door cabriolet body style and the 4 x 4 wheel drive system, it all comes up to the specific petrol engine choice they offer. The first one has a Porsche-engineered powertrain under the hood, a 6-cylinder, 24-valves 480hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 250hp engine designed by Volkswagen.

Safety

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. That aside, let's consider some other aspects which affect safety. 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, 911 offers a considerable difference of 13% more metal.

Reliability

I don't like generalizing things when it comes to reliability, although it does seem that Audi does have a slight advantage, when all the models are taken into account. These are the official statistics, while our visitors describe reliability of Porsche with an average rating of 4.0, 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. Above it all, drivers of cars with the same engine as 911 rank it on average as 3.0, while the one under the competitor's bonnet gets 4.3 out of 5.

Performance & Fuel economy

Porsche is undoubtly more agile, reaching 100km/h in 2.1 seconds less than its competitor. In addition to that it accelerates all the way to 310 kilometers per hour, 60km/h more than the other car. When it comes to fuel economy an obvious choice would be Audi TT, averaging around 10.4 liters of fuel per 100 kilometers (27 mpg), in combined cycle. That's 24% difference compared to 911!

Verdict

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 offers significantly better overall protection, taking the lead here. From there things take a different direction, with Porsche 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... It's not difficult to say then that if I'd need to make a choice, it would definitely be the 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.
