Renault said on Thursday its first-half profit rose sharply as a European market recovery and currency windfall overcame pricing setbacks for older models, driving margins to a 10-year high.
The tailwinds helped Renault lift group operating profit by almost a half to 1.07 billion euros ($1.17 billion), or 4.8 percent of sales.
"This is our best margin performance since 2005," Chief Financial Officer Dominique Thormann told reporters and analysts at Renault's Boulogne-Billancourt headquarters west of Paris.
"The group is on track to reach its operating margin target - probably sooner than planned."
Under Chief Executive Carlos Ghosn, Renault is stepping up productivity and technology sharing with 43.4 percent-owned Nissan, Daimler and other partners in pursuit of a 5 percent operating margin in 2017.
Growing business with the two affiliates accounted for about half of the group's 12 percent revenue gain - to 22.2 billion euros - as Renault sites began production of the Rogue sport utility vehicle for Nissan and Smart minis for Daimler.
