A look inside Infiniti's variable-compression engine

We're sympathetic to anyone who had trouble understanding what's going on with Infiniti's new variable-compression engine. While we got a full tech briefing on the novel VC-Turbo back in August, the visual aids were lacking. The cutaway engine Infiniti brought to the Paris show fixes all of that. You can thank the little green and pink lines on the cutaway for making the whole idea a little more clear. Click through the gallery to see two lines – one green and one pink – that represent the different strokes allowing for different compression ratios. Remember, the compression ratio is the amount of volume in the cylinder on intake compared to the amount at the end of the compression stroke. Leave more room at the end and you lower that ratio. The length of the stroke doesn't change with this system, but where it sits along the cylinder does. Hence those two lines. The variable compression ratio allows this new turbocharged engine to maximize fuel economy when the turbo isn't needed by raising the compression ratio. It will see its first use in the next Infiniti QX50 crossover, previewed by the QX Sport Inspiration concept that's also on display in Paris, and has performance targets of 268 horsepower and 288 pound-feet of torque. After, it will migrate to other Infiniti and Nissan vehicles, with transverse front-drive-based applications first in line. Eventually, it's likely to completely replace Nissan's corporate 3.5-liter V6. We'll be poking around the engine a little more in Paris today to try and get some more info. For now, enjoy those cutaway images and those friendly little lines.

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.

UAW calls on US State Department to help with Nissan plant

The United Auto Workers is calling for reinforcements in its ongoing battle with Nissan at the manufacturer's Canton, MS factory, where the Altima, Armada, Titan and NV (and eventually, the next Murano) are built. The union has been attempting to organize the employees at the factory for several years, but it's been largely unsuccessful.
Now, Reuters is reporting that the UAW is teaming with the IndustriALL Global Union and requesting intervention by the US State Department, with both groups accusing Nissan of using "threats, intimidation and fear" to keep the 5,600 workers at the facility from organizing. The two unions say this violates the guidelines of the Organization for Economic Cooperation and Development, an international organization dedicated to stimulating economic growth.
The UAW and IndustriALL are asking the State Department's National Contact Point to serve as mediator with Nissan, to make sure things play out fairly. Speaking to Reuters, though, there's at least one Michigan-based labor adviser that's skeptical of the move.
