Vauxhall design boss Mark Adams has given several hints on what the next-generation Astra and Corsa models will look like.
In an interview on YouTube, Adams said the next Corsa would take the model's design "to a different level".
"It's not too far away, it is very close," he said "We're excited about it. It takes the technology, appearance and powertrain to a new level to make us truly competitive again.
"In the UK the Corsa has been consistently first or second on the sales lists, we're confident the new car will take it to the next level".
Adams says the new-generation Corsa will major on perceived quality and will have a "sophisticated feel".
The new Corsa, which is expected to launch in 2015, has already been spotted testing at the Nurburgring. The fifth-generation car will be built on a GM platform, which itself will likely be a development of the platform used for the Vauxhall Mokka.
A range of highly efficient turbocharged petrol engines, likely ranging between 1.0 and 1.4-litres in capacity, are expected alongside a frugal 1.6-litre diesel variant.
