Asking price for Paul Walker's GT-R from Fast & Furious nearly triples [w/video]

The German owner of the only Nissan Skyline GT-R to survive filming Fast & Furious (a.k.a., The Fast and the Furious 4) has put his car up for sale following the death of Paul Walker, Yahoo Autos reports. The original sale price was reportedly an already hefty 300,000 euros ($412,110), but it has since been raised to 1,000,000 euros ($1.37 million).
Despite many well-intentioned efforts, the Skyline GT-R was (and still is) illegal to import for street use in the US, so this R34-generation GT-R and seven others were shipped here without engines and classified as kit cars to sidestep federal law. Once here, the engines were installed, and seven street-legal GT-Rs proceeded to be destroyed during the filming of F&F. But one car, the "hero" car for sale here, was driven by Walker in non-violent scenes and thus is the only GT-R that survived filming.
Then, in July 2009, the federal government cracked down on importers of these cars, seizing almost 50 GT-Rs, including this one, telling owners to export them or risk having them destroyed. The hero GT-R was therefore exported, and its whereabouts have been unknown until recently, when the current German owner allowed it to be featured in a review (watch the German-language video below). You can see the online ad (also German) of the heavily modified GT-R here, where it sits proudly with its sky-high price tag.

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.

Renault delays decision on merger with Fiat Chrysler

PARIS — Renault has delayed a decision on whether to merge with Fiat Chrysler Automobiles, a deal that could reshape the global auto industry as carmakers race to make electric and autonomous vehicles for the masses. The deal still looks likely, but faced new criticism Tuesday from Renault's leading union and questions from its Japanese alliance partner Nissan. The French government is also putting conditions on the deal, including job guarantees and an operational headquarters based in France. The French carmaker's board will meet again at the end of the day Wednesday to "continue to study with interest" last week's merger proposal from FCA, Renault said in a statement. A Renault board meeting Tuesday to study the deal was inconclusive. The company didn't explain why, but a French government official said board members don't want to rush into a deal and are seeking agreement on all parts of the potential merger. The official, who spoke on condition of anonymity in line with government policy, told The Associated Press the conditions outlined by France's finance minister still "need to be met." France and Italy are both painting themselves as winners in the deal, which could save both companies 5 billion euros ($5.6 billion) a year. But workers worry a merger could lead to job losses, and analysts warn it could bog down in the challenges of managing such a hulking company across multiple countries. And a possible loser is Japan's Nissan, whose once-mighty alliance with Renault and Mitsubishi is on the rocks since star CEO Carlos Ghosn's arrest in November. Nissan CEO Hiroto Saikawa cast doubt Tuesday on whether his company will be involved in a Renault-Fiat Chrysler merger — and suggested adding Fiat Chrysler to the looser Renault-Nissan-Mitsubishi alliance instead. Saikawa said in a statement that the Renault-Fiat Chrysler deal would "significantly alter" the structure of Nissan's longtime partnership with Renault, and Nissan would analyze its contractual relationships to protect the company's interests. If Renault's board says "yes" to Fiat Chrysler, that would open the way for a non-binding memorandum of understanding to start exclusive merger negotiations. The ensuing process — including consultations with unions, the French government, antitrust authorities and other regulators — would take about a year. A merger would create the world's third-biggest automaker, worth almost $40 billion and producing some 8.7 million vehicles a year.
