Audi TT Roadster (2015-present): dimensions and boot space

Everything you need to know about the Audi TT and TTS Roadster dimensions including width, length, height and boot size

Jan 31, 2022

The Audi TT Roadster is a two-seater convertible sports car with a focus on ease-of-use, comfort, a high-quality cabin and lots of standard equipment. The base model is great for daily driving, but if you want something more sporty and powerful, there’s also the TTS Roadster that has a more powerful engine and tuned suspension to make it better to drive.

Then at the very top of the range there’s the TT RS Roadster, which has a five-cylinder petrol engine that produces a dramatic warbling sound when worked hard and offers astonishing performance - it goes from 0-62mph in less than four seconds. This version is even more hardcore, but it’s hardly any different when it comes to size and practicality.

The Audi TT Roadster is a rival for other two-seater sports cars such as the Mazda MX-5, Porsche Boxster, Mercedes SLC and BMW Z4. The Audi’s niche within that group of rivals is that it’s really easy to drive and works well as something you can drive to work and enjoy roof-down driving on normal roads. It’s not as fun to drive as some of the others, but it’s easier to live with.

You can read on to find out more about the TT Roadster’s dimensions, and we’ve also included the size details for the higher-performance TTS and TT RS models too.


Audi TT Roadster dimensions

The TT Roadster is 4.2m long, 1.8m wide and 1.4m tall, which means it’s almost identical in size to the fixed-roof Audi TT Coupe. It’s bigger than the Mazda MX-5 in every dimension, but since its still a fairly small car overall, that doesn’t mean it’s harder to park - it’s very easy to drive overall and that’s thanks in part to the compact size.

There are only two seats but they are nice and roomy, plus visibility from the driver’s seat is good. There’s plenty of adjustment in the seat so you can get a good view of the road. The TTS and TT RS models are slightly longer than the normal model, which is because of their sporty body kits, and slightly less tall because the suspension sits lower.

Audi TT Roadster boot space

Audi TT RS Roadster

All versions of the Audi TT Roadster, including the TT S Roadster and TT RS Roadster, have a 280-litre boot. This isn’t impacted by the folding roof, as the mechanism is designed to store away in its own section behind the seats.

The luggage area opening is a little narrow in terms of getting things in and out but the space is surprisingly deep, so there’s plenty of room for shopping or luggage for a trip away for two people. It’s much more than you get in the Mazda MX-5, which has only 130 litres of space in the boot.

It’s the same as you get in an Audi A3 plug-in hybrid, which is really impressive for a sports car, though that A3's boot volume is reduced by the presence of the batteries needed for the plug-in hybrid system.

Audi TT Roadster weight

To find out how much a car weighs, you can check the kerbweight - this figure includes engine fluids, fuel and in some cases a 75kg driver, so it’s representative of what the car weighs in the real world.

The Audi TT Roadster is just under 100kg heavier than an equivalent Coupe version. This is because in removing the roof, Audi needs to add extra strength to the structure of the car under the floor to keep the car nice and rigid, along with the addition of an electric folding roof mechanism; these add a substantial amount of weight.

Lower-spec models without four-wheel-drive weigh the least, while models equipped with 'quattro' four-wheel-drive and lots of extra optional equipment weigh more - particularly the TTS and TT RS models, which are the heaviest in the range.
