Audi TT has world's fastest electronic folding roof

The soft-top Audi TT can raise and lower its fabric roof in around 10 seconds, which is incredibly fast. Add to this the fact that this function can be accessed when the car is travelling at speeds of up to 31mph and this is about as good as it can get for a convertible.

Another great feature of the roof is that the frame overlaps upon itself and does not encroach into the boot; however, its separate compartment means that boot space is limited.

The TT is aimed about 75% at the sports car market and 25% at the lifestyle. It is not a car that you would buy if you needed something spacious for your luggage, but the cabin space is ample for two people.

The 2.0-litre TFSI comes with quattro four-wheel drive and the turbocharged four-cylinder petrol engine produces 227bhp. This will propel it from 0-62mph in just 5.6 seconds and onwards to a top speed of 155mph. The TT is relatively economical, returning 42.2 mpg, and has a CO2 rating of 154g/km.

The least expensive model is the entry point diesel, which costs £31,995. This rises to £37,555 for the range-topping TFSI with S line spec, with petrol engines starting at £32,045.

The TT is a genuine head-turner and is fun to drive. Thanks to the quattro four-wheel system it handles and feels just like a junior sports car should and is likely to be irresistible to the Audi purist.
