New Abarth 124 Spider vs Audi TT Roadster

7. Audi TT Roadster 1.8 TFSI

True MPG 39.8mpg

We've always rated the TT Roadster highly, with this version's near-40mpg average fuel economy joining a list of attributes that also includes sharp handling and a gorgeous, high-tech interior.

6. Audi TT Coupé 1.8 TFSI

2019 Audi TT cornering

True MPG 40.4mpg

As good as the TT Roadster is, it's the hard-top version that we'd choose; indeed, no car has won more What Car? awards than the TT Coupé. It's even better than the Roadster to drive and that bit more practical and efficient.

5. Mini Convertible Cooper

Mini Convertible

True MPG 43.4mpg

There are more practical drop-tops than the Mini Convertible, because its rear seats are distinctly cramped. However, with strong resale values and a True MPG figure of 43.4mpg, it still makes plenty of sense.
