Renault-Nissan alliance to start autonomous EV testing

The Renault-Nissan alliance is joining the self-driving electric-vehicle party. The French-Japanese automaking collaboration, which has been selling electric vehicles to the masses since introducing the Nissan Leaf in 2010, said Monday that it will work with transportation-technology consultant Transdev on developing a fleet of self-driving EVs for testing purposes. The model of choice, though, won't be the Leaf, but instead will be the Renault Zoe. Details aren't abundant, but the group does say it will perform the field testing in the Paris area. Transdev's pedigree includes operating what it says is the world's first commercial driverless service at France's EDF campus. The company, which is majority-owned by Caisse des Depots, is no small potatoes, generating about $7 billion in revenue in 2015. Take a look at the alliance's statement here. The alliance has already been working with Microsoft on driving-technology advancements and has teamed up with Japan-based DeNA to hatch a driverless-vehicle initiative for commercial services. And in January, Nissan said its ProPilot features, which include increased self-driving capabilities, would be added to its Leaf EV "in the near future." Of course, other automakers have already jumped into the self-driving EV game. California-based EV maker Tesla has long been pushing its vehicle technology toward autonomy, and General Motors said in December that it would start field testing driverless Chevrolet Bolt EVs sometime this year. In the meantime, the Alliance is gearing up a changeover in leadership, as Carlos Ghosn said last week that he was stepping down as Nissan's CEO on April 1. Ghosn, long a champion of electric-vehicle technology, will be succeeded by Nissan co-CEO Hiroto Saikawa.

NHTSA opens investigation into Nissan's handling of airbag recall

In March of 2014, Nissan recalled eight models among its Nissan and Infiniti brands, totaling more than one million vehicles, over faulty occupant classification system software controlling the passenger airbag. The company discovered a variety of factors that would interfere with the system's ability to detect an adult passenger in the shotgun seat, resulting in an illuminated warning on on the dashboard and the passenger airbag not deploying in an accident. Yet 124 complaints submitted to the National Highway Traffic Safety Administration since the recall allege that the dealer-installed fix hasn't actually fixed the problem; some consumers say the problem persists after multiple trips to the dealer. The Detroit News reports that NHTSA is opening an investigation into the matter to determine whether a new recall is needed. The occupant sensor has been a bugbear for Nissan over the past couple of years; a much smaller recall for the issue in 2013 covered five of the eight vehicles that were recalled in 2014, and that earlier recall also continued to generate complaints after the issue had supposedly been fixed. At the same time, the company learned that in two instances there was another twist, where the dashboard warning wasn't illuminated but the passenger airbag still didn't go off in an accident. Nissan isn't alone, though, with airbag recalls on a steep upswing across the industry even before the Takata debacle.

A look inside Infiniti's variable-compression engine

We're sympathetic to anyone who had trouble understanding what's going on with Infiniti's new variable-compression engine. While we got a full tech briefing on the novel VC-Turbo back in August, the visual aids were lacking. The cutaway engine Infiniti brought to the Paris show fixes all of that. You can thank the little green and pink lines on the cutaway for making the whole idea a little more clear. Click through the gallery to see two lines – one green and one pink – that represent the different strokes allowing for different compression ratios. Remember, the compression ratio is the amount of volume in the cylinder on intake compared to the amount at the end of the compression stroke. Leave more room at the end and you lower that ratio. The length of the stroke doesn't change with this system, but where it sits along the cylinder does. Hence those two lines. The variable compression ratio allows this new turbocharged engine to maximize fuel economy when the turbo isn't needed by raising the compression ratio. It will see its first use in the next Infiniti QX50 crossover, previewed by the QX Sport Inspiration concept that's also on display in Paris, and has performance targets of 268 horsepower and 288 pound-feet of torque. After, it will migrate to other Infiniti and Nissan vehicles, with transverse front-drive-based applications first in line. Eventually, it's likely to completely replace Nissan's corporate 3.5-liter V6. We'll be poking around the engine a little more in Paris today to try and get some more info. For now, enjoy those cutaway images and those friendly little lines.
