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 CEO Hiroto Saikawa resigns, successor to be named

YOKOHAMA, Japan — Nissan Chief Executive Hiroto Saikawa tendered his resignation Monday after acknowledging that he had received dubious income and vowed to pass the leadership of the Japanese automaker to a new generation. Board member Yasushi Kimura told reporters at an evening news conference at company headquarters in Yokohama that the board has approved Saikawa's resignation, effective Sept. 16, and a successor will be appointed next month. A search is underway, he added. Calls for Saikawa's resignation, which arose after the arrest last year of his predecessor, Carlos Ghosn, on various financial misconduct allegations, have grown louder after Saikawa acknowledged last week that he had received dubious payments. The income was linked to the stock price of Nissan Motor Co., and he has said his pay got inflated by illicitly adjusting the date for cashing in. The automaker's board met to look into the allegations against Saikawa, as well as other issues related to Ghosn's allegations and corporate ethics at the company. Kimura said the income Saikawa had received was confirmed as "not illegal." Ghosn, who is out on bail and awaiting trial, says he's innocent. Kimura and three other board members, who all have backgrounds outside the company, said their investigation of the scandal over Ghosn's arrest found that alleged misconduct by Ghosn and Greg Kelly, a former board member who was also arrested, had caused 35 billion yen ($350 million) in damage to the company. Nissan will seek a repayment of the damages, Kimura said. The board said about 10 candidates are being considered as a replacement for Saikawa. They did not identify them, but said outsiders and non-Japanese are on the list. Until a successor is decided, Chief Operating Officer Yasuhiro Yamauchi will serve as interim chief, the board said. Saikawa has not been charged. "I have been trying to do what needs to be done so that I can pass the baton over as soon as possible," he told reporters earlier in the day, referring to his willingness to leave his job. Saikawa did not appear at the news conference initially, but the four board members who led the event said he would later. Saikawa has said he didn't know about the improprieties, promised to return the money and blamed the system he said Ghosn had created at Nissan for the dubious payments. Japanese media reports said Saikawa had received tens of millions of yen (hundreds of thousands of dollars) in extra compensation.

Airbag recall widens to include BMW, Chrysler, Ford and Toyota

The recall of faulty airbag inflators supplied by Takata has exploded today to grow to seven automakers. In most cases, only models in certain high-humidity regions were affected because the National Highway Traffic Safety Administration found in its investigation that moisture played a roll in determining whether there would be a problem. However, some companies opted for national campaigns. The exact number of affected models for these campaigns isn't yet known at this time.
BMW is recalling an undisclosed number of 325i, 325Xi, 330i and 330Xi models from the 2001 through 2005 model years and the 2001-2006 model year versions of the 325Ci and 330Ci for the driver side and passenger side inflators. Only vehicles currently registered in Florida, Puerto Rico, Hawaii and the US Virgin Islands are covered under this recall.
Neither Chrysler's filing with NHTSA nor its press release list the specific models affected, but a company spokesperson told Autoblog that at this time it only covers the driver and passenger side inflators for the 2006 Dodge Charger in Florida, Puerto Rico, Hawaii and the US Virgin Islands
