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, Fisker in advanced talks on investment, partnership

Nissan is in advanced talks to invest in electric vehicle maker Fisker in a deal that could provide the Japanese automaker with access to an electric pickup truck while giving the struggling startup a financial lifeline, according to two people familiar with the negotiations. The deal could close this month, said the sources, who asked not to be identified because the talks are ongoing and have not been finalized. Terms being discussed include Nissan investing more than $400 million in Fisker's truck platform and building Fisker's planned Alaska pickup starting in 2026 at one of its U.S. assembly plants, one of the sources said. Nissan would build its own electric pickup on the same platform, the source said. Nissan has U.S. assembly plants in Mississippi and Tennessee. Fisker said on Thursday, when it announced it might not be able to continue as a going concern and would cut 15% of its workforce, that it was in talks with a large automaker for a potential investment and joint development partnership. It did not name the automaker. A Fisker spokesman said the company does not comment on speculation, while Nissan officials were not immediately available to comment. Fisker shares had been down about 45% before the Reuters report but pared those losses and were trading down about 25% with a market capitalization of more than $295 million. The term sheet is ready and the deal is going through due diligence, one of the sources said. Nissan was an EV pioneer with its fully battery powered Leaf hatchback in 2010 but has since struggled in the face of nimbler new entrants. A deal with Fisker would help it move into the growing U.S. electric pickup market. Nissan's talks with Fisker comes in the wake of the former's “rebalanced” relationship with its long-time alliance partner Renault. Last year, Nissan and Renault finalised terms of a restructured alliance after months of negotiations. They aim to have cross-shareholdings of 15% as part of the deal. The more limited alliance removes certain restrictions and has opened the door for Nissan to develop growth plans in areas such as EVs and software independent of Renault, said one of the sources, who is familiar with Nissan's thinking. The Yokohama-headquartered automaker is scouring “many, many opportunities,” the person said.

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.
