Costs, insurance groups, MPG and CO2
The TT Roadster slightly undercuts the Z4, but the TTS Roadster is slightly pricier than its 718 Boxster equivalent. The TT Roadster is predicted to hold on to its value better than its key rivals, though.
The entry-level engine represents great value considering the performance it offers. It also makes a tempting company car proposition, thanks to offering fairly low CO2 emissions as far as sports cars go.
The official fuel consumption figure for our favourite engine (that in the 40 TFSI) is 44.8mpg, but you should expect it to hover around 35-40mpg in the traffic-ridden real world. Remarkably, the quicker 45 TFSI doesn’t use much more fuel, making the TT quite the fuel-sipper considering its decent performance.
Equipment, options and extras
We’d recommend sticking with entry-level Sport trim; this gets you air conditioning, heated Alcantara and leather seats, folding mirrors, 18in alloy wheels, Bluetooth, a USB port and a DAB radio.
S line trim really isn’t worth the extra unless you value the more aggressive styling it brings, although it also gives you rain-sensing wipers and larger (19in) alloys. Black Edition sits above S line and takes style cues from the TT RS, but it doesn’t add much in the way of equipment apart from piano black interior inlays. By contrast, range-topping Vorsprung models come with very few option boxes left unticked.
Unless you choose the Vorsprung, TTS or TT RS, you’ll have to pay extra for climate control and cruise control. Sat-nav is also an expensive optional extra, coming only as part of the Technology Pack.
Safety and security
Every TT Roadster comes with four airbags as standard, along with a ‘secondary collision assist’ system that helps bring the car to a stop as soon as possible after a crash. Optional kit includes a blindspot warning system, hill-hold assistance and traffic sign recognition.
Although the TT Roadster hasn’t been safety tested by Euro NCAP, the regular TT was awarded four stars out of five in 2015, a fifth star eluding it due to the absence of automatic emergency braking. We regard this as an essential safety feature, and it’s one that every Z4 has as standard.
Security experts Thatcham awarded the TT Roadster five out of five for its resistance to being stolen and four out of five for its resistance to being broken into. Every version is fitted with an alarm as standard.
