Review: Audi TT Roadster (2015)

Rating:

Impressive levels of grip. Good to drive. Efficient diesel model. Quality cabin with excellent 'Virtual Cockpit' as standard.

Still not a sports car. Jittery ride over broken British backroads. Numerous reports of water from roof unable to drain, filling battery tray and fusing MMI system.

Audi TT Roadster (2015): At A Glance

Open-top motoring is part of the Audi TT’s DNA. The original 1998 car appeared as a concept in both coupe and roadster forms before production started, so a soft-top variant of the third generation model was something of an inevitability. No doubt it will be as popular as its predecessors.

And it deserves to be popular. The latest TT Roadster is every bit as good to drive as the coupe model, with masses of grip and impressive body control. It also shares its fantastic cabin with the coupe, complete with the high-tech virtual cockpit instrument binnacle. This is a large digital display incorporating navigation, speedo, rev counter and connectivity.

The party-piece of the TT Roadster is, of course, the folding fabric roof. It can be operated at speeds up to 30mph and takes 10 seconds. Audi elected not to install a multi-piece metal roof in order to keep the proportions correct and the weight down – which means less to go wrong, but poorer security when parked up.

Refinement with the roof down is good even at high speeds, with little in the way of buffeting thanks in part to an optional retractable wind break that keeps turbulence from forming behind the seats. For those cool but dry days buyers can specify a pack that includes heated seats and ventilation that blows warm air on the your neck.

The folding roof does mean there are no rear seats in the TT Roadster, but the rear seats in the coupe are so small you can barely use them anyway. There is also an impact on the boot, which at 280 litres is okay for shopping or a weekend away, but is too shallow for anything particularly bulky.

The engine range is the same as the coupe, with a 184PS 2.0 TDI and a 230PS petrol forming the mainstay with a 310PS TTS quattro petrol at the top of the range. The petrol engines suit that TT Roadster best thanks to a great exhaust note and linear, strong power delivery. The diesel is fine too, but with the roof down it lacks the aural drama of the petrol models.

The TT isn’t quite as exciting to drive as the more expensive Porsche Boxster and it can get a bit jittery on poor roads, but it is still a tremendously impressive car. It is solidly made, good to drive and features plenty of neat, high-tech features. For those seeking a premium soft top it ticks all the right boxes.

Full specifications

From the driver’s seat the cabin of the TT Roadster is exactly the same as that of the coupe – which is a very good thing. The digital instrument binnacle is the centrepiece, incorporating the rev counter, speedometer, navigation, audio display, trip computer and connectivity into one clear, crisp, colour display.

It works really well and it doesn't take too long to get used to. There is a large control dial mounted behind the gear selector with a touch sensitive pad for inputting letters, plus there are controls on the steering wheel for changing the display when on the move. You can even minimise the rev counter and speedo, filling the screen with a large, clear map.

The placement of the infotainment screen means the rest of the cabin is uncluttered and classily laid out. The switches in the centre of the turbine-style air vents are used to set the climate control which keeps the rest of the centre dash clear and neat. It looks great and everything feels very well made, as you would expect from Audi.

The folding fabric roof can be operated when moving at speeds up to 30mph and takes 10 seconds to extend or retract, so you ought not to get caught out in a rain shower. There is an optional pack that includes an electronically controlled windbreak to keep cabin noise down at speed, along with heated seats and a neck warmer for cold days.

The fitment of the soft top means there are no rear seats in the Roadster, but they were so small in the coupe it isn’t a huge loss. The boot is less practical, however. It has a decent volume of 280 litres with the roof up or down, but it is quite shallow, so bulky items won’t fit properly.

Standard equipment includes the nifty ‘virtual cockpit’, along with useful features like DAB radio and Bluetooth, but there are also plenty of optional extras including full LED headlights and various safety gear like collision mitigating brakes.

Standard equipment:

Sport gets 18-inch 10 spoke alloy wheels, xenon headlights with LED daytime running lights, LED rear lights, heated door mirrors, manual air con, a retractable rear spoiler, Audi drive select with five driving modes, Audi virtual cockpit, MMI control system for infotainment, keyless start, sport seats finished in part leather and a first aid kit.

S line has 19-inch five arm design alloy wheels, light and rain sensors, sports seats finished in black leather, S line badges, LED headlights, LED indicator lights and S line bumpers.

What's the Audi TT Roadster (2015) like to drive?

Audi is offering the same range of engines for the TT Roadster as it is for the Coupe, meaning a choice of 2.0-litre TFSI petrol or 2.0-litre TDI diesel. The petrol produces 230PS and is offered with either a six-speed manual and front-wheel drive or a six-speed S Tronic automatic with quattro all-wheel drive.

The diesel is only available with a six-speed manual and front wheel drive and – as you would expect – it is the most economical option. Official economy is 65.7mpg and emissions are 114g/km, so tax is cheap. Performance is still impressive though, especially when on the move thanks to a hefty 380Nm of torque.

If you go for a manual, whether petrol or diesel, you’ll get a slick and precise gear change. Despite being front-wheel drive only, there’s plenty of grip thorough corners. The diesel really suits the coupe, but with the roof down in the Roadster it doesn’t sound very good.

The 2.0-litre TFSI can be paired to a six-speed S Tronic transmission and quattro all-wheel drive. This set up really helps the TT Roadster get all its power down, improving traction when cornering or when accelerating hard – plus there is a wonderful pop from the exhaust on upshifts.

The top-of-the range TTS gets the same 2.0-litre TFSI engine, S Tronic transmission and quattro system but with power boosted to 310PS. Performance is impressive, but it is perhaps a bit much for UK roads – we’d recommend the less powerful 230PS model since it's more useable in everyday situations.

The TT Roadster gets a Drive Mode Selector, which allows the driver to set up the steering weight, throttle response and, in the S Tronic, the shifting pattern to suit different situations. 

There are five driving modes - Comfort for town driving, dynamic for a twisting route, an efficiency mode for saving fuel on a long journey, an automatic mode that adapts to the situation plus a customisable ‘Individual’ mode. This allows the driver to tune various options to suit personal preferences.

Find a twisting road and the TT Roadster can be a lot of fun. Performance is good and there is plenty of grip, but broken British road surfaces upset the overly firm suspension, which can sometimes make the car jittery or even uncomfortable over partiuclarly large potholes and bumps

In fact the firm suspension doesn't do much for your confidence when pressing on at pace. In fact, though the TT Roadster is certainly fun, it would be a stretch to call it a genuine sports car – it lacks the nimbleness, agiity and composure of the admittedly more expensive Porsche Boxster. 

Nonetheless it is very good fun to drive on the right road. But it is also easy to live with in town thanks to the selectable driving modes and steering that can change its weighting – it’s light when parking or in town and heavier when driving hard. For an everyday car that is fun when you want it to be there is plenty to like about the TT Roadster.

I bought a used TT that turned out to have a water leak - is the dealer liable?

I purchased a 2016 Audi TT Roadster from large dealer group in July 2019 - the garage was taken over by another firm three weeks later. In November I heard a sloshing sound behind the passenger seat so I booked it in. The dealer informed me I had a water leak which had got into the amplifier so I would have to pay for a new amplifier and the hours worked on the car. I thought this should have been covered by my warranty or the fact I had only had the car under six months. I was informed this was not the case, I phoned Audi, the dealers and Trading Standards all to no avail. In the end, I had to wait three weeks for the amplifier to arrive it was then fitted. I collected the car Friday before last and the dealer did give me half the cost of the amplifier off the bill, although I still ended up paying £1500. When I purchased the car in July we had great weather and the car is garaged so did not go out in the rain much but of course, eventually, it was left in the rain for a few hours. The car was an Audi approved used vehicle but I doubt they tested in for a leak, so one would assume it had the leak when I purchased it. My whole problem was no one is prepared to accept responsibility because the garage changed hands after I brought the car.
I think you have a case for a small claim because the fault that led to the water ingress must have been present before you bought the car and the dealer is liable for any fault that could have been present or developing before date of sale for six months from date of sale and much longer than that if it is proven that the car was always faulty. See: https://www.honestjohn.co.uk/faq/consumer-rights/ In fact, this is quite a common fault with this generation of Audi TT Roadster.
