Infiniti's says its growth strategy is on track after a record first quarter. Nissan's premium marque managed worldwide sales of more than 52,000 vehicles for the first quarter of 2015. This is a year-on-year increase of 12%, making it the best quarter in Infiniti's sales history.

"These results are a strong proof point that Infiniti is on a successful growth path, establishing itself as one of the key premium brands globally. We have secured strong momentum and a strong foundation for the coming fiscal year," said Roland Krueger, president of Infiniti.

All four of the company's geographic regions achieved positive growth. In the US, Infiniti's biggest market, sales hit 33,800 vehicles, an increase of 8% compared to first quarter 2014. In China, the brand's biggest growth market, almost 7,900 vehicles were sold, an increase of 28% from the same timeframe last year. In the EMEA (Europe, Middle East, and Africa) and Asia & Oceania regions, first-quarter sales increased 18% and 31% respectively to approximately 6,400 vehicles and 1,400 vehicles. In the highly competitive Western Europe market, Infiniti almost doubled its sales to more than 2,000 vehicles. This represents an increase of 92% and marks a new record for the region. Other regions, such as Mexico, South Africa and Australia, also achieved record sales for the quarter.

The brand says a "successful product lineup keeps driving sustainable sales growth". The premium Q50 sports sedan - Infiniti's top selling model - enjoyed more than 50% growth from the same period last year and increased its volume in every region of the world. Q70 achieved over 50% growth in the Americas and China. QX80, which is one of Infiniti's top SUVs, saw 21% growth. In March, Infiniti launched a refreshed version of the QX50 in China. This vehicle has been presented at the recent New York auto show for the US and will be introduced to other markets subsequently.

"We are pleased to see that Infiniti has made significant progress, transforming itself into a global premium automotive brand," said Krueger. "We are confident that we will achieve another year of strong performance."
