Nissan Recalls More Than One Million Vehicles For Air Bags

Nissan is recalling just over one million cars, SUVs and vans because the front passenger air bags may not inflate in a crash. It's the company's second recall to fix the same problem. The recall affects the Altima midsize car, Leaf electric car, Pathfinder SUV and Sentra compact models from the 2013 and 2014 model years, as well as the NV200 Taxi van and Infiniti JX35 SUV from 2013. Also covered are the Infiniti QX60 and Q50 SUVs from 2014. In documents filed with the National Highway Traffic Safety Administration, Nissan says the vehicles' computer software may not detect an adult in the passenger seat. If that happens, the air bags won't inflate. Nissan will notify owners and dealers will update the software for free. The recall is expected to start in mid-April. Most of the vehicles were recalled in February of last year for a similar problem. Dealers replaced seat sensors, but Nissan said it continued to get consumer complaints and warranty claims in vehicles that had been repaired. Front passenger seats have sensors that determine the passenger's weight and turn off air bags off if a child is on board. The malfunctioning sensors can turn the air bags off even if an adult is in the seat. Nissan received three reports of air bags failing to inflate in a crash. Spokesman Steve Yeager said in an e-mail that he is not sure if anyone was hurt in those incidents. There have been no deaths due to the problem, he said. The recall affects almost 990,000 vehicles in the U.S., another 60,000 in Canada and small numbers in other countries, Yeager said. Related Gallery Nissan Searches For Identity In America

Basic Continuously Variable Transmission explained with Legos

In recent years, the search for better fuel efficiency and smoother shifting has produced automatic transmissions with double-digit gears. Alternatively, the same quest has boosted the popularity and usage of a different type of automatic transmission without any fixed gears, the continuously variable transmission, or CVT. YouTuber Sariel's Lego Workshop recently took the time to build a CVT demonstration model out of Legos to help explain how they work. Sariel begins by showing the model's input and output shafts that are parallel to each other. Each shaft has a cone attached to it, and they are inversely placed so that the large part of one cone is next to the small part of the other cone. The two cones are connected using a rounded rubber band.  By shifting the rubber band up and down the cones, the machine changes the effective ratio between the cones. So, a 1:4 ratio can be smoothly transitioned to 4:1. No clutch is required to operate the mechanism, and it eliminates hitches or pauses between gear changes. CVTs are also advantageous over 9- or 10-speed automatics in that they are far less complex and weigh less.  To demonstrate how the CVT operates in a vehicle, Sariel used a joke about Top Gear. The original Top Gear is represented by a faster-moving car that has the rubber band around the large part of the cone on the input shaft. Top Gear without former hosts Richard Hammond, Jeremy Clarkson, and James May is represented by a slow-moving car with the rubber band around the large part of the cone on the output shaft.  For an even more detailed explanation of how CVTs work — albeit one that doesn't involve toys — you can click here.

2015 Nissan Micra Cup First Drive [w/video]

A light mist falls on the Circuit Mont-Tremblant. Looming gray skies threaten that more wetness is in store. I'm already nervous about scooting a tiny Nissan around a challenging course in rural Quebec. This damp chill isn't helping. It's an unlikely day to drive an improbable racecar: the Nissan Micra, one of the smallest and cheapest cars sold in Canada. Luckily, the weather and my trepidation ease up. Laps around this gorgeous road course prove to be a lot of fun. The Micra isn't a bad little car, and racing them, well, that sounds like a riot. Nissan is using the time-tested tool of motorsports to raise the profile of its new subcompact with the Micra Cup, a spec series that launches with a pair of races the weekend of May 22-24. It will be followed by five more weekend doubleheaders through the summer and into the fall, including a support race before Formula One's Canadian Grand Prix in June. The investment for Nissan is low, and the six races will all be run in Quebec, a province with a European level of motorsports fervor. Despite the damp conditions, I'm eager for my turn to wheel the diminutive Micra around the Circuit Mont-Tremblant, a 15-turn, 2.65-mile course nestled in the Laurentian Mountains of Quebec. Don't be fooled by the idyllic setting, Mont-Tremblant hosted F1 grands prix in 1968 and 1970, Can-Am and Trans-Am races in the 1960s and 70s, and a Champ Car race as recently as 2007. Racing trim suits the Micra, and the car looks snappy dressed in red, white, and gray livery. I climb into the cabin and strap into the racing harness. It's easy to get comfortable in this basic interior. Nerves steadied, I grip the steering wheel, ease the Micra into first gear, let out the clutch, then shift to second and exit the pit lane. Thankfully I'm not the first guy to get out on the track in this car, so the tires are warm. The rain has stopped, but I'm cautious at first. The track surface is still a little slick, and the front-wheel-drive Micra's rear tires can easily come unbuttoned. As I lap the circuit, my confidence grows. My helpful instructor flashes three and four fingers from the passenger seat to indicate the gear I should be in, and then urges me to floor it in open areas. He's more confident than I am, but as I dart around the track, the adrenaline starts flowing. My peak speed is maybe 93 miles per hour, but that's not the point.
