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.

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.

Mercedes was set to sell version of Nissan Titan, now Infiniti might instead

Mercedes-Benz Titan. Mercedes-Benz Frontier. Mercedes-Benz pickup truck. None of these things roll off the tongue particularly well. We'd like to think that's the reason Daimler opted to kill the idea of rebadged Titan and Frontier pickups from corporate ally Nissan. In reality, the execution before the Frankfurt Motor Show was due to more complicated issues.
Yes, Mercedes, byword for German luxury, style and quality, would have slapped a three-pointed star on a pair of Japanese pickup trucks that have failed to resonate with consumers in the world's largest truck market. That slapping of badges isn't much of an exaggeration, at least on the outside. According to the report from Road & Track, the truck's front clip would have been tweaked, but beyond that, the sheetmetal would have been unchanged. The interior would have received a more thorough going-over by the team at Mercedes, while the suspension and noise, vibration and harshness tuning would have also received significant attention.
The trucks would have ended up being sold through the light-commercial branch of Mercedes-Benz - the same folks that will happily sell you a Sprinter van - had the deal gone through. Issues arose, though, first with the engines. Mercedes wanted a wider range of powertrains to allow it to tune models for specific markets, while Nissan said it couldn't engineer the wide variety of engines that MB wanted to drop under the hood. For the smaller truck, meanwhile, MB was interested in a hybrid or plug-in variant, according to R&T, although this was also shot down by Nissan.
