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 cooks up throwback livery for Le Mans

Nissan may not have won the overall 24 Hours of Le Mans before – Mazda remains the only Japanese automaker to have done so – but when it returns to Le Mans this year, it will be armed with other bragging rights. And it's that past accomplishment that Nissan is celebrating with this throwback livery. Twenty-five years ago, Mark Blundell set a blistering qualifying lap in the No. 24 Nissan R90CK, lapping La Sarthe in 3:27.020. That was enough to put the Datsun on pole for the race, and though it never made it to the finish line, it set a record that stands to this day when it hit 227 miles per hour on the Mulsanne straight – even with the chicanes in place. That car wore a blue livery with white and red that still holds a place of honor in the hearts of racing fans. So to mark its return to Le Mans a quarter century later, Nissan is decking out its new GT-R LM Nismo in a tribute livery that will be worn by the third entry the company will be fielding in the race. Nissan celebrates 1990 pole lap of Le Mans with retro livery for LM P1 car LE MANS, France – Nissan today revealed a very special livery that will feature on the No.21 Nissan GT-R LM NISMO at Le Mans. Exactly 25 years ago, at the peak of the Group C era, Mark Blundell put the Nissan R90CK on pole position with a stunning 3:27.020 lap of the Le Mans circuit. The No.21 Nissan GT-R LM NISMO is Nissan's third LM P1 car that will be raced by current Super GT Champion Tsugio Matsuda (JAP) and two winners of GT Academy, Lucas Ordonez (ESP) and Mark Shulzhitskiy (RUS). The No.24 Nissan R90CK will also appear at Le Mans in a special parade to mark the anniversary of the pole lap in the hands of the man who took it to the top of the tables 25 years ago, Mark Blundell. The 1100bhp car may not reach speeds of 366 km/h (227 mph) as it did in 1990, but it is certain to grab everyone's attention. "That lap of Le Mans is certainly a very fond memory for me," said Blundell. "It was one of those moments where time stood still and everything went perfectly. You remember those moments, as they don't happen all that often. It's great to see Nissan celebrating that time with the retro livery on the #21 Nissan GT-R LM NISMO. I can't wait to see it on track at Le Mans." "Our racing heritage is hugely important to us," said Darren Cox, Global Head of Brand, Marketing & Sales, NISMO.

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.
