FCA-Renault revival may hinge on willingness to cut Nissan stake

Fiat Chrysler Automobiles and Renault are looking for ways to resuscitate their collapsed merger plan and secure the approval of the French carmaker's alliance partner Nissan, according to several sources close to the companies. Nissan is poised to urge Renault to significantly reduce its 43.4% stake in the Japanese company in return for supporting a FCA-Renault tie-up, two people with knowledge of its thinking also told Reuters. It is still far from clear whether any concerted effort to revive the complex and politically fraught deal can succeed. FCA Chairman John Elkann abruptly withdrew his $35 billion merger offer in the early hours of June 6 after the French government, Renault's biggest shareholder, blocked a vote by its board and demanded more time to win Nissan's backing. Nissan representatives had said they would abstain. The failure, which FCA and Renault blamed squarely on the French government, deprived both companies of an opportunity to create the world's third-biggest carmaker with 5 billion euros ($5.6 billion) in promised annual synergies. It also shone a harsh light on Renault's relations with Nissan, which have gone from frayed to fried since the November arrest of former alliance Chairman Carlos Ghosn, now awaiting trial in Japan on financial misconduct charges he denies. REVIVAL TALKS Italian-American FCA — whose brand stable encompasses Fiat runabouts, Jeep SUVs, RAM pickups, Alfa Romeo luxury cars and Maserati sports cars — has so far turned a deaf ear to suggestions by French officials that its merger proposal could be revisited. But since the breakdown, Elkann and his French counterpart Jean-Dominique Senard have had talks about reviving the plan that left the Renault chairman and his Chief Executive Thierry Bollore upbeat about that prospect, three alliance sources said. Renault and a spokesman for FCA declined to comment. One of Elkann's senior advisors on the Renault merger bid, Toby Myerson, was expected at Nissan headquarters in Yokohama on Monday for exploratory discussions with top management, two people with knowledge of the matter said. Nissan CEO Hiroto Saikawa is likely to attend. Myerson did not respond to a message from Reuters seeking comment. The meeting comes amid mounting strains that may preclude compromise, after Senard warned Saikawa that Renault was prepared to block key Nissan governance reforms in a dispute over board committees.

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.
