• TT might cost less to run than expected
• Used diesel boasts impressive claimed economy
• Performance versions much thirstier

Starting with the 40 TFSI claimed fuel economy is rated at 46.3mpg, while the 45 TFSI is capable of 42.8mpg in manual form. The S Tronic performs better with 43.5mpg, while a Quattro model returns up to 40.4mpg. 

Keep things tame and you might even crack 40mpg with the TTS. Audi claims the S Tronic model is capable of 40.9mpg, but if you manage this you’re clearly not making the most of the power and performance on tap. The manual version has slightly lower claimed economy figures of 38.7mpg.

Unsurprisingly, the TT RS is nowhere near as economical as other TTs, especially if you can’t ignore the sonorous 2.5-litre five-pot under the bonnet. 

Claimed economy sits at 34.4mpg when equipped with 19-inch alloy wheels, while examples with larger 20-inch alloys fall to 33.6mpg. Bear in mind that this is in very favourable conditions. If you enjoy driving your TT RS, you won’t see more than 30mpg. 

Used Audi TT running costs

Starting with the 1.8 TFSI, the S Tronic version is the most fuel-efficient, claiming up to 47.9mpg. The manual version of this engine returns up to 47.1mpg.

Go for the more powerful 2.0 TFSI with a manual gearbox and you could see up to 46.3mpg, while the S Tronic version delivers 43.5mpg claimed economy. Opt for Quattro and it falls slightly to 42.8mpg.

The 2.0 TDI Ultra boasts the most impressive economy figures, capable of achieving up to 60.1mpg, while the S Tronic-equipped Quattro model will still return up to 52.3mpg.

Choose the 40 TFSI, and CO2 emissions of 138g/km, making it the greenest of the TT line-up. 

The 45 TFSI Quattro S Tronic emits 161g/km, while the front-wheel drive version produces 148g/km. Go for the manual and you’ll see 150g/km. 

The TTS isn’t far behind, despite the power advantage. The manual version produces 168g/km, but the S Tronic is much lower at 159g/km.

Again, the TT RS is the dirtiest of the lot, producing 187g/km when fitted with 19-inch alloy wheels, while those with 20-inchers produce 192g/km.

The RS is the only TT model to claim different figures depending on the size of the alloy wheels. On some cars the emissions figures can vary depending on the wheels, but the regular TT models are all consistent.

• No official recalls for the TT…
• Though there were some teething troubles
• Should be reliable overall

While there have been no official recalls for this TT, there was some initial problems with the car’s Virtual Cockpit digital instruments. It was the first car to feature the system so it’s not totally unsurprising that there were problems with the software and electronics.

However, if you’re buying a secondhand model, any issues should have been sorted under warranty, and if you’re buying a new one, the system is now so widespread through the Audi range that it’s been honed and any issues should have been ironed out. In our experience, Virtual Cockpit works well.

Everywhere else, the TT uses fixtures and fittings from elsewhere in the Audi range, while the engines and gearboxes are used throughout the VW Group on hundreds of thousands of cars, so there should be little to be concerned about.
