The national car manufacturer said more than 25,000 bookings had been received for the X70 thus far, making it the most popular Proton model in the line-up for 2019.
Chief executive officer Li Chunrong said Proton hoped to reduce waiting times for customers.
Proton said while total industry volume grew by 11.8% year on year in March, the company outpaced the market with a 46.1% increase in registrations, equivalent to a growth rate nearly four times higher than the industry as a whole.
“For the first three months of 2019, the cumulative registration figure is 43.5%, or more than six times the TIV number of 6.7%.
“The overall results position Proton ahead of all rival brands for the month and first quarter of 2019,” it said.
Li said Proton was confident of continued sales growth when updated models of its vehicles are launched later this year.
“With delivery numbers of the Proton X70 increasing, we are hopeful of being able to reduce waiting times for our customers. At the same time, we are working diligently to ensure each unit we deliver is perfect as our aim is for our new SUV to be the highest rated vehicle for the Initial Quality Study rankings for Malaysia in 2019,” said Li in a statement.
