Mazda Turnpike in Japan shut down for racing

The people behind Motorhead Magazine in Japan clearly have some friends in high places. Not only did they manage to shutdown eight kilometers of the Mazda Turnpike up the Hakone mountain, but they invited some of the country's premiere racers to take a drive up the hill. This wasn't just a Sunday cruise either. Featuring a BMW Z4 from the Super GT series, a classic Ford GT40, two flavors of Nissan GT-R and two takes on the Subaru Impreza WRX STI, these guys came ready to run. When an opportunity to let racecars challenge a curvy mountain road presents itself, you don't squander it. Thankfully, the folks at Motorhead knew that and outfitted the course with a plethora of cameras and high-quality sound equipment to capture the action. The result is nothing short of sublime. Take the video's urging to turn up your speakers for this one, and watch as these racers hit ludicrous speeds in a beautiful place never meant for them.

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.

Nissan adds 500 jobs in Mississippi for Murano production [w/video]

Nissan is bolstering its workforce at its Canton, MS factory, adding 500 workers for this fall's production kickoff of the heavily redesigned Murano crossover.
"The addition of Murano to our portfolio, coupled with the continued growth and success of the Canton plant, will move us even closer to our goal to build more than 85 percent of the vehicles we sell in the US right here in North America," said senior vice president of manufacturing, supply chain management and purchasing for Nissan's North American ops, John Martin.
The Murano will eventually be exported to over 100 markets and will be built alongside the current Xterra, Frontier, Titan and Armada. The addition of 500 jobs to the Canton facility elevates its total workforce past 6,000 people.
