The latest contract builds on an existing partnership and sees Bill Plant replace its former fleet of i20s with the i30 hatchback, which will make up almost half its vehicles.

The company, which runs a nationwide driving school and training centre for instructors, said that it was important to have the right car for instructors and pupils.

Jake Plant, general manager, commented: 'A city car is the wrong kind of vehicle for learners, it is just too small. You need a family hatch and for us the i30 is the right size. Hyundais are right for us, they are reliable and stylish and an appropriate size for instructors and pupils. It is very important to us that instructors and pupils like the car, and they love the i30.'

Mr Plant added: 'Fuel consumption is important for our instructors which is why we went for the diesel i30 with ISG, Hyundai's stop-start system.'

Guy Pigounakis, Hyundai sales director, said: 'After doing business with them last year for more than 500 i20s we're delighted that Bill Plant Driving School is renewing its fleet with the i30.'

Hyundai will deliver the first of the all-diesel fleet this month.
