Red Bull keeps 2015 RB11 F1 challenger under wraps [UPDATE]

UPDATE: A previous version of this post suggested that Daniil Kvyat drove for Red Bull last year, when he actually drove for its affiliate team Toro Rosso. The text below has been updated with the correct information. This season will be one of new beginnings for Red Bull Racing. It's the first time in three years that it's not returning to the Formula One grid as defending champions, and without a world champion at the helm. But return it will to fight to regain its title, and this is the car with which it intends to do so. Revealed ahead of the season's first test session in Jerez this weekend, the new RB11 is wearing a bold camouflage "testing livery" of the type we're more accustomed to seeing on road-going prototype than on a racing car. Expect it to be replaced by the familiar blue, red and yellow by the time the season kicks off in Melbourne next month. Though the camouflage may keep certain aero developments disguised (if not altogether hidden) from the prying eyes of its rivals, the sloping nose mandated by the new regulations is plain to see. Otherwise the new RB11 is likely more of an evolution rather than a revolutionary clean-sheet redesign over the RB10 that returning hot-shoe Daniel Ricciardo drove last year, to be joined this season by Daniil Kvyat, who's been promoted from Toro Rosso to replace departing four-time champion Sebastian Vettel. Whether they can succeed, however, will largely depend on the engine. Red Bull has emerged as the primary partner for engine supplier Renault (sister company to the team's title sponsor Infiniti). In fact, after Lotus switched to Mercedes (and assuming Caterham doesn't make it back to the grid), Red Bull and its sister team Toro Rosso will be the only teams running Renault engines this season. The team says it has worked closer than ever with the French automaker to develop the Renault power unit, but chances are slim that they'll be able to catch up to Mercedes given the restrictions on engine development. If anyone can catch the Silver Arrows, though, it'll surely be Red Bull – the only other team to win a grand prix last season. THE RB11 REVEALED After an intensely busy off-season, Infiniti Red Bull's Racing's 2015 Formula One car, the RB11, has hit the track and begun testing at the Circuito de Jerez in Spain ahead of the new season.

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.

Infiniti spruces up the Q50 for 2018

Though overshadowed by the literally larger QX80 Monograph SUV concept, Infiniti's revised 2018 Q50 still made an appearance at the stand in New York. It joins a long list of cars including the Acura TLX, Hyundai Sonata, Mitsubishi Outlander Sport, VW Golf, and Toyota Sienna and Yaris that all went under the knife for the show. The Infiniti Q50's update may be one of the most mild, though, as it only consisted of cosmetic changes. Up front, the grille has been enlarged and given more prominent swoops at each corner. On the S version, sharp creases appear on either side of the primary grille and descend down to the lower, center grille. The outboard grilles of the front bumper have changed shape, too, and they now feature contrasting black plastic trim. The standard Q50 has a new bumper, as well, and though less aggressive than the S version, it still looks sporty with a more pronounced chin spoiler. Both iterations of the 2018 Q50 share the same tail end. The main change is in the rear bumper. A center diffuser has now appeared at the base. The contour of the diffuser is echoed by two creases in the bumper at progressively higher points. On the S model, the panel between the diffuser and the first crease is painted black, and the diffuser is painted in the body color. The standard model's entire bumper is painted in body color, and the diffuser looks to be a more muted black or gray. Inside, even fewer changes have been made. A new steering wheel with reshaped thumb grips is now included. Infiniti also added new stitching to the instrument panel cover and leather shift knob. You'll be able to examine all of these changes up close at an Infiniti dealer this summer when the cars arrive. Related Video: This content is hosted by a third party.
