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 4-cylinder, 16-valves 225hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 211hp 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. Still, apart from the official crash test results there are other things we need to be aware of. 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 marginal difference of 9% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears 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 5.0, while the one under the competitor's bonnet gets 3.4 out of 5.

Audi TT is a bit more agile, reaching 100km/h in 0.8 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 243 kilometers per hour, 7km/h less than the other car. When it comes to fuel economy the winner has to be A5 Coupe, averaging around 6.6 liters of fuel per 100 kilometers (43 mpg), in combined cycle. We can't ignore that 9% difference compared to Audi TT.

A5 Coupe 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 much better overall protection, which launches it ahead of the other contender. 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. Anyway, that's the most objective conclusion I could've came up with and it's based solely on the information found on this website. Aspects such as design, practicality, brand value and driving experience are there for you to measure them out.
