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 coupe body style and the 4 x 4 wheel drive system, it all comes up to the specific diesel engine choice they offer. Both the engines are Volkswagen-engineered . The first one has a 4-cylinder, 16-valves 177hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 170hp one.

Safety

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, but it doesn't do much to help us decide between the two. Furthermore, when it comes to weight, a factor that most people underestimate, A5 Coupe offers a considerable difference of 10% more metal.

Reliability

I don't like generalizing things when it comes to reliability, although it does seem that Audi displays higher than average breakdown numbers, at least on all of the models level. That's the official data, while our visitors describe reliability of Audi with an average rating of 4.2 out of 5. Some independent research have also placed A5 Coupe 50% below average, and TT 35% above the first one. That apart, owners of different cars powered by the same engine as A5 Coupe rank it on average as 3.9, while the one under the competitor's bonnet gets 4.2 out of 5.

Performance & Fuel economy

Audi TT is a bit more agile, reaching 100km/h in 0.3 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 226 kilometers per hour, 2km/h less than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 5.2 liters of fuel per 100 kilometers (54 mpg), in combined cycle.

Verdict

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. When it comes to performance, both vehicles provide similar experience, so I wouldn't point any of them out. A5 Coupe still consumps less fuel, which needs to be taken into consideration. It's really tough to make a final decision here, but if I'd need to, I'd say Audi TT. In any case that's my personal view, built upon all the data available to me. What should decide here though is the way you feel about the two vehicles, and I hope you'll find my guidelines useful in the process.
