The manufacturer is offering 0% finance over three years for the i30 in Comfort and Style trims and, for the first time, the entire Santa Fe range.
For buyers of the range topping i30 Premium, meanwhile, can spread the payments over four years.
Hyundai has also extended its PCP finance offer on its biggest selling model, the i10 supermini, in Classic trim.
On the 1.1 litre petrol Comfort, buyers could pay just £99 per month across 35 months, with a one off payment of £254 and a £1,617 deposit.
They can then either make the final payment and own the car, or hand the keys back to the dealer.
