Chip shortage will hit Nissan, Suzuki and Mitsubishi in June

TOKYO — A global chip shortage is forcing Nissan and Suzuki to temporarily halt production at some plants in June, sources with direct knowledge of the plans told Reuters on Friday. Nissan will idle its factory in Kyushu, southern Japan, for three days on June 24, 25 and 28, while making production adjustments during the month at its Tochigi and Oppama plants in Japan, three sources said. Nissan will also temporarily halt production of some of its models at its Mexico plant, they said, declining to be identified because the plan is not public. "A global shortage of semiconductors has affected parts procurement in the auto sector. Due to the shortage, Nissan is adjusting production and taking necessary actions to ensure recovery," a Nissan spokeswoman said. Suzuki will idle its three plants in Shizuoka prefecture from three to nine days, two sources said, also declining to be identified because the plan is not public. The plan "has not been confirmed," a Suzuki spokesman said, explaining that while the carmaker gave its provisional production plan to auto part makers, it is still making adjustments to minimize the impact of the chip shortage. Elsewhere, Mitsubishi will reduce production by 30,000 vehicles in total in June at five plants in Japan, Thailand and Indonesia, a spokeswoman said, adding that the impact has already been factored into its earnings outlook for the current fiscal year.

Nissan Leaf becomes least expensive 5-seat EV with massive price drop

In a roundtable interview today at the North American International Auto Show, Nissan CEO Carlos Ghosn announced a $6,400 price drop for the base-model 2013 Nissan Leaf. Last year's base model was $35,200, while the new base-level 2013 Leaf S starts at $28,800. Ghosn says the new prices make the Leaf the least expensive five-seater electric for sale in the US.
Some of the lower cost is due to a difference in content from last year's low-end model to this year's. But a sizable portion can be chalked up to the Leaf's production moving from Japan to Tennessee. The 2013 Leaf is not only assembled in the US now, but its lithium-ion batteries and the car's electric motors are manufactured in the same southern state.
The Leaf SV will be priced from $31,820 for 2013 compared to $35,200 last year. The high-end Leaf SL now starts at $34,840, down from the 2012 model's $37,250. These models also have differences in content. One big one is a new 6.6-kWh charger that reduces charging times pretty dramatically.

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.
