About 333,000 new cars, worth £4.95 billion, are expected to be registered in September on the newly available plate numbers, according to the Society of Motor Manufacturers and Traders (SMMT).
The other month that features a plate change is March and it remains the busiest, but September traditionally sees a fifth of the year's trade being done.
Motorists in the UK have a choice of upwards of 300 models which offer the efficient use of fuel and many other pieces of technology. A new car is a valuable asset and should be protect with an first-ratecar insurance policy.
Paul Everitt, SMMT Chief Executive said "September is a significant month for the UK motor industry and the wider economy.
"A strong month for new vehicle registrations will help put both on the right track. Franchised dealers have a fantastic range of exciting new models on offer, each with enhanced levels of fuel efficiency, safety, comfort and affordable finance.
"These advantages make it a great time to buy a new car and motorists should visit their local dealer to secure a new 62-plate in September." Plate numbers are now changed every September and March using the year as a means of identification. Previously up to 1999 it was altered alphabetically each year. The current systems identifies a car through the first two digits representing the region it was registered in and the next two the year.
