Paris: French car maker Renault says its earnings soared last year thanks to lower restructuring costs, and forecasts further growth in 2015. France’s number two car maker behind PSA Peugeot Citroen says in a statement Thursday net profit more than doubled to €1.89 billion (Dh7.9 billion, $2.1 billion) last year, while new car and light truck registrations climbed 3.2 per cent to 2.7 million vehicles. Renault’s 2013 earnings were weighed down by a €1.3-billion restructuring charge. The maker of the best-selling Clio hatchback forecast 2 per cent growth in Europe’s car market this year but warned it expects “high volatility” in its main emerging markets. Europe’s car market grew 5.7 per cent in 2014, the first positive year-on-year result since the global financial crisis began in 2007.
