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's Carlos Ghosn offers to wear electronic ankle tag if released

TOKYO — Ousted Nissan Chairman Carlos Ghosn has offered to wear an electronic ankle tag and hire guards to monitor him in an unusual bid to secure his release on bail after two months of harsh detention in Japan for alleged financial crimes. Ghosn is also willing to remain in Tokyo, where he has leased an apartment, and post stock he owns in Nissan as collateral, his spokeswoman said. A new bail hearing is set for Monday after an earlier request was denied due partly to concerns the French executive was a flight risk. His release would allow Ghosn to meet more frequently with his lawyers and defend himself before the board of Renault, where he remains chairman and CEO, amid calls for his removal and potential moves to restructure the Nissan tie-up. Ghosn denies any wrongdoing as he awaits trial on charges of financial misconduct. "I will attend my trial not only because I am legally obligated to do so, but because I am eager to finally have the opportunity to defend myself," Ghosn said in a statement on Sunday. "I am not guilty of the charges against me, and I look forward to defending my reputation in the courtroom." Meanwhile, Ghosn's wife, Carole Ghosn, has written to French President Emmanuel Macron to discuss her husband's situation, her public relations representative said. The representative, Devon Spurgeon, confirmed a report in French paper Journal du Dimanche that a letter had been sent to Macron this month, but declined to provide details. France wants a full merger As Ghosn's arrest on Nov. 19 continued to cloud the outlook for Nissan's three-way alliance with France's Renault and Mitsubishi Motors, Nissan said it was not the time to discuss revising the partners' capital ties. Ghosn, who spearheaded Nissan's turnaround two decades ago, had pushed for a deeper tie-up between Nissan and Renault, including possibly a full merger by 2020, despite strong reservations at the Japanese firm. "We are not at the stage for such discussions," Nissan CEO Hiroto Saikawa told reporters on Monday. Saikawa said he had not heard directly about a reported proposal by the French government to integrate the Japanese carmaker's management with Renault. The Nikkei newspaper reported on Sunday that a French government delegation had informed Tokyo that it would seek an integration of Renault and Nissan, most likely under the umbrella of a single holding company. "Since I have not heard this directly, I cannot comment," Saikawa told reporters.

Nissan, Mitsubishi Motors unveil light EVs for Japan

KURASHIKI, Japan — Japan's Mitsubishi Motors Corp and Nissan Motor Co unveiled their first jointly developed light electric vehicles (EVs), aiming to draw more Japanese drivers to battery-powered cars by offering low-priced micro models. The two Japanese automakers, part of an alliance with French carmaker Renault SA, were once considered trailblazers in Japan's EV market but have struggled to attract customers and face challenges from fast-growing newcomers such as Tesla. "I'm confident that (the new vehicles) representing the alliance will be a game changer for electric vehicles in Japan," Nissan Chief Executive Officer Makoto Uchida said at an unveiling of the new models in the western Japan city of Kurashiki. The automakers are hoping to leverage their presence in Japan's unique market for micro "kei" cars, which account for nearly 40% of cars on the road in Japan. The three companies' alliance early this year detailed a five-year plan to invest $26 billion on EV development, including kei cars. Nissan, which produces the Leaf and the Ariya electric vehicles, will offer its first light EV, the Sakura, starting at about 1.78 million yen ($13,891) after factoring in a government subsidy, and with a range of 180 km (112 miles). Mitsubishi Motors, maker of i-MiEV electric cars, will release the "eK cross EV" starting from about 1.85 million yen including the subsidy, also with a range of 180 km. Both automakers said they would start selling their new line-up of electric "kei" cars this summer. "People who used to think that EVs are too expensive will become a little more interested in EVs and will be willing to give them a try," said Riho Suzuki, Nissan regional product manager.
