Suzuki has taken 2,100 car orders due to the scrappage scheme.
Customers trading in their old car for the £2,000 can get a new Suzuki Alto for £4,795.
Apart from the upturn in Alto sales, other models in the range are also proving to be high in demand with a sharp increase in sales of Swift and Splash models.
David Seward, Suzuki UK sales and marketing director, said: “The Alto and Splash models had already got off to a very good start in March and now registrations across the whole range are climbing steadily as customers take advantage of the savings on offer.
“Our dealers are reporting greatly increased showroom traffic and some are experiencing a four fold increase in orders.”
