Hyundai has taken more than 17,000 orders since the beginning of the scrappage scheme, averaging almost 300 orders per day.
The most popular car under the scheme is the i10, taking one in 12 of all orders placed in the UK under scrappage.
The carmaker said extra supplies of the car have been secured from the factory and the company’s import centre in Tilbury, Essex is to get cars to customers quickly.
Hyundai’s managing director Tony Whitehorn said: “It’s crucial that we get the cars out to buyers as soon as possible, and not only because the customers want their nice new car.
"The government funds are fast running out, and we want to make sure Hyundai buyers can secure their slice of the scrappage handout before the scheme ends.”
