Strains between France and Italy risk Renault-FCA merger

PARIS/ROME — Fiat Chrysler's proposed $35 billion merger with Renault has cheered investors, won conditional support from Paris and Rome and even earned cautious backing from trade unions. Beneath this veneer, however, the bold attempt to create the world's third-largest carmaker risks becoming rapidly embroiled in the fraught relationship between France's europhile President Emmanuel Macron and Italy's euroskeptic leaders. For while Deputy Prime Minister Matteo Salvini hailed the proposal as a "brilliant operation," Italy's creaking, state-subsidized Fiat factories are likely to bear the brunt of any production-related cost savings. FCA and Renault said this week that more than 5 billion euros ($5.6 billion) of annual savings would come mainly from combining platforms, consolidating powertrain and electrification investments and the benefits of increased scale. Salvini and France's Finance Minister Bruno Le Maire, who called the deal a "good opportunity" to build a European industrial champion able to compete with China and the United States, have both said they want guarantees on local jobs. "It's not every day that I agree with Salvini," said Le Maire, whose government appears to hold the trump cards. When it comes to where any job cuts fall, France will be helped by its existing 15 percent holding in Renault, whose superior efficiency at its five French plants makes it better placed to handle a supply glut, the demise of the petrol engine and the investments needed for electric and autonomous vehicles. "It will take many, many years to find real savings, and ugly political and operational realities can often swamp the potential of such new entities," Bernstein analyst Max Warburton said of the FCA-Renault plan to rival Japan's Toyota and Germany's Volkswagen. Advantage France? As well as Italy's government having to cope with the aftermath of European elections, which coincided with news of the FCA-Renault plans, political leaders in Rome were only informed shortly before the deal was made public, an FCA source said. This contrasted with the way the French government was treated, with Fiat Chrysler Chairman John Elkann, a fluent French speaker, letting it know of his merger proposal to Renault weeks ago, a French government official said.

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.
