Vauxhall has added an automatic transmission to its Astra TwinTop line-up.

The new model is the first in the Vauxhall range to mate the 138bhp 1.8-litre VVT petrol engine to an auto gearbox. The auto TwinTop goes from 0-60mph in 11.9 seconds and has a top speed of 117mph.

The 1.8-litre automatic TwinTop Sport costs £19,330 on the road, while the higher trimmed Design model is priced at £20,030. Both variants are on sale now.
