Club to restore amazeballs Datsun Safari Rally Z

Thanks to the Nissan Restoration Club, a legendary rally car is coming back to life. At the recent Nissan 360 media event, the Japanese automaker announced that its restoration club is bringing the Safari Rally Z back to original running condition. A variant of the Fairlady Z (or Datsun 240Z in the US), the Safari Rally Z has a fastback coupe body and a 215-horsepower inline-six engine. It won East African Safari Rally championships in both 1971 and 1973. The restoration is scheduled for completion this December.
Formed in 2006, Nissan's Restoration Club is comprised of 60 volunteer members who are passionate about Nissan's historic racecars. The club's past restoration projects include the 1964 Skyline racecar and 1947 Tama electric vehicle. Read the press release below for all the details on the latest restoration, and check out the gallery for photos of the Safari Rally Z as well as the 1972 Fairlady 240Z.

Pretty scenery alert: Nissan Leaf drives up a volcano on Maui

Gravity taketh away but gravity giveth back, Nissan is trying to teach all of us. The Japanese automaker has posted a two-minute video about Maui resident Neil Wagner using his Nissan Leaf to catch the legendary sunrise over the volcano in Haleakala National Park. After climbing the more-than-10,000-foot elevation, the Leaf is shown having lost about 84 percent of its usable battery capacity. The finer point, though, is that electric vehicles have a regenerative braking system, meaning that the downhill ride and all of its switchbacks actually replenish battery capacity. Of course, the video didn't show exactly how much of that capacity was replenished, but the point is well-made, and with really cool scenery. Sales for the Leaf have already been strong this year. Through the first three months of the year, Nissan boosted sales 46 percent from 2013 numbers up to 5,184 units. This is after more than doubling sales last year to 22,610 units. And, for anyone curious, there are six publicly-accessible plug-in vehicle charging stations in Kahului and another eight in Lahaina, two of Maui's largest cities, according to the US Department of Energy. We're pretty sure that Mr. Wagner already knows that but we're going to take notes in case we need to make the sunrise drive one day. For now, we're going to check out Nissan's two-minute video below one more time. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.

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.
