Renault plans engine patch

Renault plans engine patch, Renault said on Tuesday it planned a software advancement to cut nitrogen oxide (NOx) abuse from its agent engines, which accept appear beneath blaze for their almost top emissions in the deathwatch of the Volkswagen test-rigging scandal.

Following VW's acknowledgment endure September for application software "defeat devices" to bluff U.S. authoritative tests, the French carmaker has fatigued accessible and broker analysis over its own emissions performance.

As of Monday's bazaar close, Renault shares had collapsed 14 percent back the Jan. 14 acknowledgment that board raided its offices this ages over suspicions of emissions artifice - back about denied by aggregation and government officials. At 7.36 a.m. ET, the banal was up 1.8 percent at 75.50 euros.

Besides VW's absolute cheating, the agent aspersion has acute acquaintance of real-world NOx emissions by the broader auto industry far beyond those abstinent in awry European authoritative tests - with Renault generally cited by campaigners as a part of the affliction offenders.

Bollore, agent to Chief Executive Carlos Ghosn, had already appear endure ages that Renault was dispatch up investment to advance its NOx emissions performance.

The carmaker has appropriate 50 actor euros ($54 million) to advancement its accepted diesels, while accelerating the 1.2 billion euro development of their next bearing - dubbed Euro 6D - from 5 years to three.

Renault's almost poor almanac on NOx - abhorrent for a host of respiratory illnesses - contrasts acutely with its achievements in developing agent and gasoline engines that accomplish industry-leading levels of ammunition economy, and accompanying low carbon dioxide emissions.

Separately, Renault accepted on Tuesday it was abandoning added than 15,000 agent versions of its Captur mini-SUV to actual an engine processor accountability that disabled its bankrupt after-treatment system, causing NOx levels to soar.

The recall, appear by French Environment Minister Segolene Royal beforehand in the day, was launched in November in acknowledgment to problems detected endure July, Bollore said.

The official agency accustomed by Royal is currently testing 100 car models from all above automotive brands to analyze on-the-road emissions with authoritative test-bench array as it looks for any affirmation of added boundless analysis rigging.
