Nissan recalls over 120,000 Altimas due to... spare tire inflation?!

A pressure regulator that over- or underinflated spare tires for five days earlier this year has led to a recall of 123,308 units of the 2013 Nissan Altima. Sedans that were manufactured from March 21-26 are those possibly affected by the temporary tire snafu, the recall for which will begin on May 3.
Those notified of the issue can take their sedans to their local Nissan dealer, who will check the tire pressure and correct it if necessary, but we imagine owners can probably just whip out a tire gauge to check and adjust the inflation for themselves. Should you need it, there's an official notice from the National Highway Traffic Safety Administration below with a few more details.

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 seeks tech tie-up without Renault as alliance nears end of road

Nissan is developing growth plans in areas such as software and electric vehicles (EVs) independent of Renault SA as the automakers work to finalize terms of a sharply limited alliance, said seven people with knowledge of the matter. Japan's third-biggest automaker by sales is seeking a partner outside the auto industry to develop software that connects vehicles to cloud-based services, two people involved in discussions said, without elaborating on candidates. That would address a relative weakness for Nissan as it tries to make cars "smarter and more connected," one of the people said. It is also working on an expanded strategy for all-battery and plug-in EVs for North American and Asian markets that will be for Nissan alone, they said. The revelations come as the alliance oversight board met this week to discuss a rebalance that will see Renault cut its stake in Nissan to 15% from 43% — matching the size of Nissan's stake in Renault — and Nissan gain reciprocal voting rights. Under the deal, to be finalized by mid-year, Nissan will also invest in the French automaker's new Ampere EV business. Imbalance had long riled Nissan executives who complained Renault did not pay its fair share of costs for innovation and development. Nissan's emerging strategy reflects a belief within the automaker that the 23-year-old alliance has run its course for many of the biggest challenges it faces, the people said. While Nissan sees continued savings in shared parts procurement with Renault, it has no plan to provide engineering support to Ampere, said two of the people, who all asked not to be identified because talks between the pair are ongoing. It also has no plan to provide its e-Power hybrid technology to a gasoline powertrain-focused joint venture Renault has with China's Zhejiang Geely Holding Group Co Ltd and Saudi Aramco Base Oil Co JSC, two of the people said. GOING SOLO Such go-it-alone thinking is shaping a longer-term plan that could be announced by year-end focusing on improved operational performance, electrification and software allowing self-driving and other "connected car" features, one of the people said. "Even if Renault gets something from Nissan, benefits moving in the other direction are hard," a second person with knowledge of Nissan's stance said.
