Carlos Ghosn: What misconduct is he accused of?

TOKYO — Japan was shocked by news that Nissan Motor Co. Chairman Carlos Ghosn, who was widely respected for rescuing the carmaker from near bankruptcy, was arrested on Monday for alleged financial misconduct. Nissan said that Ghosn, who is also chairman and CEO of Renault and chairman of Mitsubishi Motors, would be fired from his post as Nissan chairman on Thursday. What is Carlos Ghosn accused of? Nissan CEO Hiroto Saikawa told a packed press conference on Monday night that the company had found that Ghosn had been using corporate money for personal purposes and under-reporting his income for years in official company filings to the Tokyo Stock Exchange. Another board member, Greg Kelly, was also deeply involved in the misconduct, Nissan said. Saikawa said he couldn't elaborate as the cases are being investigated by prosecutors, who have declined to comment. Prosecutors said that Ghosn and Kelly conspired to understate Ghosn's compensation over five years starting in fiscal 2010 as being about half of the actual 9.998 billion yen ($88.9 million). Public broadcaster NHK said Nissan paid billions of yen to buy and renovate homes for Ghosn in Rio, Beirut, Paris and Amsterdam, citing unnamed sources. The properties had no business purpose and were not listed as benefits in TSE filings, NHK said. Ghosn, 64, has not been formally charged. The Asahi newspaper reported that he and Kelly had submitted to prosecutors' questions after getting off a plane on Monday afternoon at Tokyo's Haneda Airport. Saikawa confirmed they had been arrested. Ghosn and Kelly have not been seen since, and their exact whereabouts are not known. Suspects are typically taken to the Tokyo Detention Center, which is linked to the Tokyo District Public Prosecutors Office. How did this come to light? Nissan's Saikawa said Ghosn's alleged improprieties came to light through a whistleblower, after which the company began an internal investigation and informed prosecutors. Japanese media reports say the informant is a member of Nissan's legal department. The Asahi reported, without citing sources, that the informant gave the prosecutors information in a plea bargain, implying the person may have provided evidence in exchange for a lighter sentence. How much control did Carlos Ghosn have? After becoming CEO of struggling Nissan in 2001, Ghosn was hailed as the automaker's savior by implementing an aggressive cost-cutting plan.

Infiniti's new VC-T changes the rules of small turbocharged engines

The upcoming Infiniti QX50 crossover does not get our pulse racing, no matter how shapely the QX Sport Inspiration concept that previews it may be. No midsize SUV does, to be fair. But it has something special under the hood – the world's first production variable-compression-ratio engine. That means the QX50's 2.0-liter turbo four, which makes 268 horsepower and 288 pound-feet of torque, will have up to 27 percent better fuel economy. Here's how it works. The trend of moving to smaller, turbocharged engines carries with it one big falsehood. Under low load when the turbo isn't needed, these engines are less efficient than an equivalent engine without a turbo because of the low compression ratio the turbo requires. That is, if you never need the extra power, you're wasting fuel. Turbocharged (and supercharged) engines use a lower compression ratio to prevent detonation. When you force extra air in a cylinder and mix it with fuel, it's more likely to prematurely go boom. Lowering the compression ratio prevents this problem, but it's less efficient. Infiniti's VC-T promises the best of both worlds, with a compression ratio that ranges from 8.0:1 for high-power turbo needs to a 14.0:1 ratio for fuel-sipping efficiency. At its heart the VC-T engine is a simple idea, but it's complicated to explain. Consider yourself warned. The photo below from Infiniti serves as a good visual overview. For the truly nerdy, this patent application covers the mechanical concept. Instead of having the pistons connected to the crankshaft, Infiniti's engine has a pivot arm with a connection on each end. One end connects to the piston, the other connects to a second lower shaft, which is controlled by an actuator arm. At any given time the engine's pistons move up and down according to the lobes on the crankshaft. But the actuator arm can change the angle of the pivot arm up and down. That is, the pistons still move in the same motion with the same stroke, but phase the entire stroke up or down. Move the pivot up and there's less room at the top, which means a higher compression ratio. Move the pivot down and the compression ratio goes down, too. As an added bonus, the lower shaft eliminates the need for counter-rotating balance shafts. Infiniti says this system works constantly and can vary the compression ratio to any number between 8:1 and 14:1. It also uses electronic variable valve timing on the intake valves to switch into Atkinson-cycle combustion for greater efficiency.

IIHS gives good ratings to 4 of 8 midsize pickups in crash test

Versions of the Toyota Tacoma, Chevrolet Colorado and GMC Canyon Crew Cab earned top ratings in a new crash test of midsize pickup trucks from the Insurance Institute for Highway Safety, while two versions of the Nissan Frontier earned marginal ratings. But the organization gave poor marks to all eight pickups tested for their dim headlights. Overall, four of the eight pickups evaluated earned good ratings for protecting occupants in all five crash test categories — the Tacoma double cab along with crew cab versions of the Colorado, Canyon and Tacoma. But the poor headlights and lack of an automatic emergency braking system blocked any of the pickups from qualifying for the IIHS's Top Safety Pick awards. The study looked at two pickup body styles using 2017 models: crew cabs, which have four full doors and two full rows of seating, and extended cabs, which have two full front doors, two smaller rear doors and compact second-row seats. It subjected each to five tests, and it evaluated the performance of front crash prevention systems and headlights. The Toyota Tacoma crew cab was the only pickup in that class that earned a good rating for structure in the small overlap test, which replicates what happens when a vehicle clips a tree, pole or another vehicle that has crossed the center line. The model's Access Cab extended-cab version was rated similarly, though its structure was rated acceptable. "This group of small pickups performed better in the small overlap front test than many of their larger pickup cousins," says David Zuby, the Institute's executive vice president and chief research officer. "The exception was the Nissan Frontier, which hasn't had a structural redesign since the 2005 model year." The extended-cab versions of the Chevy Colorado and GMC Canyon earned acceptable ratings, while both the Nissan Frontier king-cab and crew-cab models were rated marginal. Toyota says its 2018 Tacoma will feature upgraded headlights and a standard autobraking system that can detect pedestrians. "Headlights are basic but vital safety equipment. Drivers shouldn't have to give up the ability to see the road at night when they choose a small pickup," Zuby said.
