Martin Wilson (pictured) has become sales director at Hyundai, taking over from Guy Piguonakis.
Piguonakis takes on Wilson's old role as fleet director, while dealer development director Paul Wills will now report to CEO Tony Whitehorn.
Hyundai's UK sales last year grew 7.5% to 88,257 - the highest total in the manufacturer's 33 years of vehicle sales in the UK.
Its retail sales increased by 4%, while fleet sales grew 10.7%.
"After a hugely successful year for Hyundai Motor UK Ltd in 2015, we are now entering the next phase of development moving towards our 2020 target of more than 100,000 sales and a 5% market share," said a spokesman.
"We have a host of all-new products which will take us into new segments of the market in that time.
"In preparation, we have completed a senior level reorganisation in the sales division, with specific focus on three key areas for future business growth."
The changes in full are:
- Martin Wilson, currently fleet director, has been appointed to the role of sales director - reporting directly to the president and CEO Tony Whitehorn. His responsibilities will include sales operations, sales and market planning and Tilbury Import Centre.
- Guy Pigounakis, currently sales director, has been appointed to the role of fleet director - reporting directly to Whitehorn. Pigounakis's sales experience will be focused on the continued development of Hyundai Motor UK's fleet operations - maximising the company's presence across all sales channels.
- Paul Wills, currently dealer development director, will continue in the role which will now report directly to Whitehorn.
These changes will be effective immediately.
