Nissan's crowdsourced Project Titan is ready to tackle Alaska [w/videos]

Alaska still offers Americans the chance to really experience the wilderness, and Nissan is challenging its Titan pickup to its offroad extremes with a little help from its fans. After crowdsourcing a heap of mods, the company is handing it over to two Wounded Warrior Project Alumni to do their worst in the backcountry to see what the truck can do.
Nissan last experimented with the crowdsourcing idea on its Project 370Z in 2012 but might have taken things even further this time. For Project Titan, the automaker let fans vote on 10 different areas to customize on a 2014 Titan Crew Cab PRO-4X. To fit the rugged look, the company covered it up with a custom digital-camouflage wrap with a Wounded Warrior Project emblem and even outfitted its all-terrain camping trailer in a similar scheme. An LED lighting rig was also added to the new bull bar and roof rack to brighten the night. For a just little more grunt, the 5.6-liter V8 was outfitted with a Nismo cold-air intake and Borla cat-back exhaust, and to keep from getting stuck, the pickup got an upgraded suspension with more travel and 18-inch wheels with 35-inch Nitto offroad tires. The interior was also slightly revised with big GPS system and custom embroidered seats.
Now, it's time to see if the truck's mods can handle what the Alaskan wilderness can throw at it. The two Wounded Warrior Project Alumni are just starting their expedition and are expecting snow on the way. Scroll down to watch three build videos for the Titan and read Nissan's official announcement. You can also follow their journey on Nissan Trucks' Facebook page.

Convocation of eagles takes over bed of Nissan pickup

Let this be a lesson to those of you who plan to visit Unalaska, Alaska (yes, it's a real city on Unalaska Island in the Aleutian Islands): If you park at Safeway with a garbage bag full of fish fillets in your pickup's bed, the eagles will find you. That's what happened above when an unidentified man parked his Nissan and returned to find a convocation of bald eagles feasting on his fish.
Neither the man nor those parked near his truck could get to their cars for fear of getting a beatdown from The 'Murica Bird, and police were called to break it up, which they did with neither beast nor fowl injured in the process.
Other than being awesome watching, other things we can take away from this video are the question who comes up with bird gathering names (a "murmuration" of herons and an "unkindness" of ravens?), and the bounty of this comment left by user "Abraham" at the KUCB news report: "It's just that the luxury edition has so much more eagle, it saddens me to think of you missing out." See what caused it all in the video below.

Infiniti's new VC-T changes the rules of small turbocharged engines

The upcoming Infiniti QX50 crossover does not get our pulse racing, no matter how shapely the QX Sport Inspiration concept that previews it may be. No midsize SUV does, to be fair. But it has something special under the hood – the world's first production variable-compression-ratio engine. That means the QX50's 2.0-liter turbo four, which makes 268 horsepower and 288 pound-feet of torque, will have up to 27 percent better fuel economy. Here's how it works. The trend of moving to smaller, turbocharged engines carries with it one big falsehood. Under low load when the turbo isn't needed, these engines are less efficient than an equivalent engine without a turbo because of the low compression ratio the turbo requires. That is, if you never need the extra power, you're wasting fuel. Turbocharged (and supercharged) engines use a lower compression ratio to prevent detonation. When you force extra air in a cylinder and mix it with fuel, it's more likely to prematurely go boom. Lowering the compression ratio prevents this problem, but it's less efficient. Infiniti's VC-T promises the best of both worlds, with a compression ratio that ranges from 8.0:1 for high-power turbo needs to a 14.0:1 ratio for fuel-sipping efficiency. At its heart the VC-T engine is a simple idea, but it's complicated to explain. Consider yourself warned. The photo below from Infiniti serves as a good visual overview. For the truly nerdy, this patent application covers the mechanical concept. Instead of having the pistons connected to the crankshaft, Infiniti's engine has a pivot arm with a connection on each end. One end connects to the piston, the other connects to a second lower shaft, which is controlled by an actuator arm. At any given time the engine's pistons move up and down according to the lobes on the crankshaft. But the actuator arm can change the angle of the pivot arm up and down. That is, the pistons still move in the same motion with the same stroke, but phase the entire stroke up or down. Move the pivot up and there's less room at the top, which means a higher compression ratio. Move the pivot down and the compression ratio goes down, too. As an added bonus, the lower shaft eliminates the need for counter-rotating balance shafts. Infiniti says this system works constantly and can vary the compression ratio to any number between 8:1 and 14:1. It also uses electronic variable valve timing on the intake valves to switch into Atkinson-cycle combustion for greater efficiency.
