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 coupe body style and the 4 x 4 wheel drive system, it all comes up to the specific petrol engine choice they offer. Both the engines are Volkswagen-engineered . The first one has a 6-cylinder, 24-valves 333hp unit, while the other one gets its power and torque from a 5-cylinder, 20-valves 340hp one.

The fact that the Audi TT 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, A5 Coupe offers a considerable difference of 14% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Audi displays higher than average breakdown numbers, all the models observed together. These are the results of an independent reasearch, while our visitors describe reliability of Audi with an average rating of 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. That apart, owners of different cars powered by the same engine as A5 Coupe rank it on average as 4.3, while the one under the competitor's bonnet gets 5.0 out of 5.

Audi TT is a bit more agile, reaching 100km/h in 0.3 seconds less than its competitor. In addition to that it accelerates all the way to 250 kilometers per hour, exactly the same as the other car does. When it comes to fuel economy the winner has to be A5 Coupe, averaging around 8.1 liters of fuel per 100 kilometers (35 mpg), in combined cycle. We can't ignore that 14% difference compared to Audi TT.

Audi TT 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. It all continues in the same direction, with Audi TT offering somewhat better performance, just enough to call it quicker. It does come at a cost though, and that's the fuel consumption... It's really tough to make a final decision here, but if I'd need to, I'd say A5 Coupe.
