Nissan plans to slash May car output in Japan by 78%

TOKYO — Nissan plans to slash the number of cars it produces at home in May by 78% from last year, as the impact of the coronavirus shakes the troubled automaker which has already been struggling with falling sales. As global automakers reel from plunging sales amid lockdowns imposed in many countries to curb the spread of the virus, the hit is particularly severe for Nissan, whose profitability has been deteriorating as it grapples with the turmoil that followed the ousting of former Chairman Carlos Ghosn. Nissan plans to manufacture around 13,400 vehicles next month, according to documents seen by Reuters, compared with nearly 61,000 units made in May last year. The cut represents a big hit to Nissan's plant in Kyushu, southern Japan, which the automaker plans to operate on a single shift for much of this month and all of next month, due to a lack of demand for the Rogue Sport SUV crossover model, according to the documents, which are not public. Output will decline 70% from initial plans to build around 44,800 units. In June, domestic production will be cut to 33,700 vehicles, a drop from around 63,700 units last year, and down 43% from a previous plan for around 59,300. Nissan declined to comment on its production plans. The automaker has stopped production at its plant in Tochigi, north of Tokyo, since early April, and plans to keep output suspended through the end of May. Periodic stoppages at Nissan's Oppama plant in Kanagawa Prefecture have been common since earlier this month. The coronavirus pandemic has piled urgency on Nissan's efforts to downsize, after two years of falling sales, deteriorating margins and depleting cash reserves has forced the company to restructure. Nissan's management has become convinced that the company needs to be much smaller and its latest recovery plan due next month will likely assume a cut of 1 million cars to its annual sales target, senior company officials told Reuters earlier this month. Automaking partner Mitsubishi, also suffering from a cut to demand for its cars, is planning to slash domestic output by nearly one-third over the next two months. As both Nissan and Mitsubishi struggle with tanking sales, production plans show one bright spot: Nissan is planning an increase in production of the Nissan Dayz minicar model, which Mitsubishi manufactures for Nissan for the Japanese market.

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.

Nissan recalling 909k vehicles globally over accelerator issue

Nissan is issuing a massive recall that will see the Japanese automaker repair 908,900 vehicles worldwide, with nearly 100,000 of the affected models in the United States. While an official recall notice from Nissan or the National Highway Traffic Safety Administration is not yet available, Reuters has been able to confirm the recall with Nissan.
Nissan's recall is kind of the opposite of the Toyota unintended acceleration, in that it covers a lack of acceleration. According to the report, a sensor in the gas pedal can develop faults, leading to a sluggish acceleration or an outright stall regardless of how much throttle the driver dials in. The huge recall covers mostly Japanese domestic models like the Serena, X-Trail, Lafesta and Fuga, which make up for 764,800 of the 908,900 faulty vehicles. However, 98,300 Infiniti M sedans are being recalled in the US, although it's unclear at this time which model years and trims are affected. The remaining vehicles are found in Europe and Oceania, according to Nissan spokesman Chris Keefe.
No injuries or accidents have been reported due to the faults. The 90-minute repair will see techs replace the accelerator pedal and tweak the engine control programs. We'll update this story as soon as Nissan or NHTSA makes an official statement.
