For next Nissan CEO, priority is profit before Renault partnership

The next head of Nissan Motor Co will need to prioritize a recovery in profits at the troubled Japanese firm ahead of trying to fix its relationship with top shareholder Renault SA, executives and analysts say. Reviving earnings would strengthen the carmaker’s hand in negotiations with its French partner, and is something Renault itself would welcome as the owner of a 43.4% stake in Nissan. JapanÂ’s second-largest automaker said on Monday CEO Hiroto Saikawa would step down on Sept. 16 after he admitted to being overpaid in breach of company rules. ItÂ’s another heavy blow for Nissan, which is already reeling from the arrest of former chairman Carlos Ghosn last year and a subsequent plunge in earnings. Its stock is down 20% this year. For SaikawaÂ’s yet-to-be-named replacement, the top priority will be lifting profits from a more than decade low. Earnings have been undercut by years of heavy discounts and low-margin sales to rental firms that have cheapened NissanÂ’s brand image. Renault, which has unsuccessfully sought a full-blown merger with its larger partner, is likely to give the Japanese firm time to focus on its turnaround, a Nissan executive said. “It goes without saying recovery is the biggest priority,” the executive said, declining to be identified because the information is not public. “We have RenaultÂ’s understanding on that.” Tensions in the Nissan-Renault partnership worsened after GhosnÂ’s arrest. He is awaiting trial in Tokyo on financial misconduct charges that he denies. The strain has sparked investor concern about the future of the Franco-Japanese automaking alliance at a time when car companies desperately need scale to keep up with sweeping technological changes like electric vehicles and ride-hailing. Nissan executives have long complained about their unequal partnership with Renault, which saved the Japanese firm from bankruptcy in 1999. Nissan holds a 15% stake in Renault, but without voting rights. Tokyo is also seen as being uneasy about the French governmentÂ’s 15% holding in Renault, which makes Paris an indirect shareholder in Nissan. “Profitability is likely to remain under pressure and it (Nissan) is unlikely to promptly reach an agreement with Renault over the future shape of the alliance,” analysts at Standard & PoorÂ’s said in a note. Tensions worsened when Renault tried to in vain to merge with Nissan and then Fiat Chrysler.

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.

Panoz mulls suing Nissan for ZEOD RC's Deltawing likeness

Imitation might be the sincerest form of flattery, but in racing, where something as simple as a car's shape can lead to a competitive advantage, imitation can be a big no-no. That reality is being played out right now, with the DeltaWing prototype and the Nissan ZEOD RC. The two cars, as you can see from the images above, bear a striking resemblance to each other. They're so similar, in fact, that Dr. Don Panoz, one of the big names behind the DeltaWing program, is assigning some legal eagles to investigate any patent infringement.
The similarity shouldn't be a shock, though. Both cars are penned by Ben Bowlby, and the DeltaWing - which will be arriving as a coupe in the very near future - had Nissan branding and power for a not-insignificant amount of time. But for Panoz, the ZEOD RC's resemblance is just a bit too much, as he told Autoweek, "It's been interesting to watch people from Nissan trying to dodge the question, but the fact is that in their own press release they admit that the configuration of the ZEOD is the same as the DeltaWing. And we do have patents, in fact another one was just issued last week. We are in discussions with our legal advisors and we'll see what happens."
Frankly, it's not difficult to see what Panoz means. The general shape of the ZEOD RC, with its wide rear track and narrow front track arrangement - not to mention the headlights mounted over the rear wheel arches and any arrangements not visible under the body - are so reminiscent of the DeltaWing that differences like the shape of its closed cockpit and more upright front end might not prove different enough to avert Panoz's legal action. We'll stay with this one and let you know as more becomes available.
