Favourable response to the new range has prompted studies into a go-faster version.
Managing director Paul Williams said: 'Reaction has been so positive that we are looking at introducing a more powerful model with lowered suspension, extra trim and Sport badging.
'Our prices start at £5,495, so we expected interest to be relatively high. But the response has been so good that we're now also thinking about launching a one-make racing or rally series.'
With 10,000 sales in the first few months, the South Korean brand may register 33,000 cars this year, thereby making inroads in the fleet sector.
Williams added: 'We've spent 18 months talking to the industry. The Picanto is picking up interest from fleets and I expect our next car, the Cerato, to account for about 1,000 corporate sales this year.'
Due on sale in July, the C-sector hatchback and saloon range will also carry aggressive pricing.
