Nissan does its best Google Glass impression with 3E headgear [w/video]

The jury may still be out on whether it'll be legal to drive with Google Glass on your nose, but that doesn't mean automakers are going to sit around waiting to see which way the wind blows in one jurisdiction or another. Mercedes-Benz, for example, is already working on ways to integrate its infotainment system into Google Glass, but Nissan is taking things a step further by developing its own wearable tech.
The device is called Nissan 3E, and we don't have much information to go on at this point - just a couple of images, a terse press release and the highly stylized (and rather painful-looking) video below. The Japanese automaker lists internet connectivity and communication as the primary features. But we'd have to assume that, if an automaker is developing it, the device would have some relevance to, you know... driving.
The possibilities are endless, extending from turn-by-turn directions and track information to vehicle metrics and intuitive control of the car's auxiliary controls. We'll have to wait until we get to Tokyo to find out more, but between this and the smartwatch concept it revealed in Frankfurt, Nissan seems to be on a bit of a gadget streak lately.

Nissan Quest under investigation for inaccurate fuel gauges

After receiving 12 complaints in the last 14 months, the National Highway Traffic Safety Administration has begun a preliminary investigation into a fuel gauge issue with the 2007 Nissan Quest. Drivers have reported that the fuel level gauge will show there's gas in the tank when there actually isn't - in two cases, the digital distance-to-empty gauge indicated more than 70 miles of remaining range - and it will stall out.
This is the second time the 2007-model-year Quest has been involved in the same fuel gauge issue. In 2010 Nissan recalled seven models, including the Quest, from the 2005-2008 model years because of faulty fuel readings. The 12 vehicles in this latest complaint could have slipped through the cracks then, but we'll find out more when NHTSA updates its progress with the investigation into the estimated 37,656 units.

This tiny 1.5L engine from Nissan makes 400 horsepower

Back in 2012, Ford packed its tiny 1.0-liter EcoBoost three-cylinder in a carry-on suitcase, destined for use in the Fiesta here in the US. In June, Nissan will pack its tiny new three-cylinder engine in a 24 Hours of Le Mans racecar. Nissan's don't-call-me-DeltaWing ZEOD RC racecar will still be able to tackle a single lap under full electric power, but the rest of the time it will be powered by the new 1.5-liter turbocharged three-cylinder engine.
Holding the lightweight engine (at right) is Nismo president Shoichi Miyatani, and he's likely smiling because that 40-kilogram (88-pound) engine packs quite a punch with 400 horsepower and 280 pound-feet of torque. Nissan would like to take a moment to point out this engine's power-to-weight is better than the engines currently used in Formula One racecars. Scroll down for more information on this new race engine, which we'll see in action at Le Mans in June.
