Nissan officials answer to angry shareholders on red ink, Ghosn scandal

Smoke engulfs the Nissan logo as workers burn tires during a protest in Barcelona, Spain, where the automaker is closing its plant, costing 3,000 direct jobs. (AP/Emilio Morenatti)     TOKYO — Nissan Chief Executive Makoto Uchida told shareholders Monday he is giving up half his pay after the Japanese automaker sank into the red amid plunging sales and plant closures in Spain and Indonesia. Uchida apologized for the poor results and promised a recovery by 2023, driven by cost cuts and new models showcasing electric-car and automated-driving technology. “We will tackle these challenges without compromise,” he said at a live-streamed meeting. “I promise to bring Nissan back on a growth track.” Executives for the company also blasted suggestions in media reports of a conspiracy within the company to oust Carlos Ghosn. The former chairman's 2018 arrest in Japan on financial misconduct charges has led to much speculation that the move was orchestrated by Nissan executives who opposed closer ties with partner Renault. “I know that in books and the media there has been talk about a conspiracy, but there are no facts whatsoever to support this,” Motoo Nagai, chairman of NissanÂ’s auditing committee, told shareholders at the companyÂ’s annual general meeting. Responding to demands from a shareholder to address the speculation, Nagai argued that the investigation into Ghosn was conducted both internally and by outside law firms. All the worldÂ’s automakers have been hurt by nose-diving sales caused by the coronavirus pandemic. But the problems are especially serious for Nissan, which already was fighting to salvage its reputation after the financial misconduct scandal of former star executive Ghosn. Nissan, based in Yokohama, Japan, sank into its first annual loss in 11 years, reporting a 671.2 billion yen ($6.3 billion) loss for the fiscal year that ended in March. It has not given a projection for this fiscal year, citing uncertainties over the virus outbreak. One angry shareholder got up and said executives should give up more of their pay since investors were getting zero dividends. Another said Nissan needed to do more to strengthen its governance, arguing things have been getting worse, not better, since the departure of Ghosn.

Toyota, Honda, Nissan and more collaborating to increase fuel efficiency

Toyota, Honda, Mazda, Nissan, Subaru, Mitsubishi, Suzuki and Daihatsu have announced an alliance that will see a push to improve fuel economy from both gas-powered and diesel-powered engines by as much as 30 percent before the end of the decade.
The newly assembled Research Association of Automotive Internal Combustion Engines put the roughly $20-million project together, with the Japanese government committing to half the cost while the eight manufacturers will chip in the rest.
According to Automotive News, the automakers will team up and share basic research on internal-combustion engines in a bid to cut costs. Eventually, the results of the research will find its way into a production vehicle, although it's unclear just when we'll see the fruits of this partnership on the road.

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.
