The A-pillar and floorplan strengthening the Roadster receives over the hard-top TT helps it to feel brilliantly stiff and, together with light but quick steering and high grip levels, this is an agile, faithful car that has the ability to gratify. Yes, this is a front-wheel-drive car that will stray at its front axle if pushed too hard, and it can be a little predictable if you prefer your roadsters to be rear-wheel drive. But is it engaging? Certainly.
From the driver's seat, if you’re extremely long-legged, you might prefer to have your seat slid a bit farther back, but the chances are that drivers of most shapes and sizes will be able to get comfortable, thanks to lots of adjustment to the supportive seat and steering wheel. You’ll have no problem working out the dashboard controls, because there are only a handful of clearly labelled buttons set neatly into the fascia.
All Roadsters feature Audi's 12.3in Virtual Cockpit colour display where you’d normally expect to find the instrument dials. Audi's MMI infotainment system is easy to use; you control it via a large rotary dial between the seats and there are also handy shortcut buttons to take you directly to specific functions. The Roadster’s interior really is special, too, with high-quality and solid-feeling materials throughout.
Boot space is quite a bit smaller than that of the TT Coupé, but you’ll still fit more in it than you would in a BMW Z4's or a Mercedes SLC's. What’s more, the size of the load area stays the same whether the hood is up or down, whereas many rivals with folding metal roofs eat into their load space.
Should I buy one?
You certainly won't feel short-changed. The 1.8 has all the performance you're likely to want for a reduced price, but crucially, it doesn't stop being a brilliant open-top. Audi really has nailed interior quality on the head, while the Roadster's infotainment, refinement and comfort are some of the best you can buy at this level.
In fact, travelling a tad more slowly in the 1.8 and enjoying the open-air experience probably makes it a more fitting choice. Without doubt, the TT remains a more rounded package than an equivalent Z4 or Mercedes SLC with it, even if those rivals' looks and rear-driven set-up will continue to win their own sales.
