Nissan CEO plans to deliver 'raw details of the misconduct' to Renault

TOKYO/PARIS — Nissan Motor's CEO plans to meet one-on-one with the deputy CEO of automaking partner Renault in Amsterdam this week, sources told Reuters, amid tensions over the future of the alliance after Chairman Carlos Ghosn's arrest last month. The meeting would be the first face-to-face interaction between Nissan's Hiroto Saikawa and Renault's Thierry Bollore since Ghosn was arrested on Nov. 19 in Tokyo. It would take place alongside regular top-level, monthly talks between the partners and Mitsubishi Motor Corp that will be held over two days from Tuesday, according to one of the sources familiar with the matter. Saikawa, who took over from Ghosn as CEO last year, is planning to discuss at the meeting with Bollore possible changes to the partnership's management and operations with an eye to continuing the alliance, another source who is close to Nissan's management said. The talks in Amsterdam could provide Saikawa with an opportunity to try and convince Renault executives of the gravity of Ghosn's alleged misconduct discovered during an in-house investigation by the Japanese automaker. They are being held a day after Saikawa rebuffed a demand from Renault for an extraordinary shareholder meeting that would have offered the French car maker a chance to weigh in on Ghosn's replacement as chairman and on other Nissan board appointments. Mitsubishi Chairman Osamu Masuko said late on Monday he will attend the Amsterdam meetings via video conference. A Nissan spokesman said Saikawa would attend meetings with alliance partners in Amsterdam from Tuesday, but declined to comment on the possibility of the one-on-one meeting with Bollore. Ghosn was charged last week alongside alleged accomplice Greg Kelly and Nissan itself over the company's failure to declare $43 million in deferred income that Ghosn had arranged to be paid while chairman and CEO. Both men remain in custody. The scandal has shaken the Renault-Nissan-Mitsubishi alliance, with Saikawa calling for changes to weaken Renault's control as he moved to oust Ghosn in the week of his arrest. Renault directors were briefed last week on the Nissan investigation that led to Ghosn's arrest but reiterated their earlier decision to keep him in office as chairman and CEO. But the Renault board has yet to be given direct access to Nissan's findings, which are being closely held by Renault lawyers answering to Ghosn's long-standing chief of staff and head of legal affairs at Renault, Mouna Sepehri.

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.

2018 Jeep Grand Cherokee vs. midsize crossovers and SUVs: How they compare on paper

In a world full of SUVs and crossovers all competing for similar buyers in similar segments, there are still some models that find their own little niches that lack such fevered fighting. The Jeep Grand Cherokee is one of those vehicles. It's an oddball in the sense that it's a midsize crossover SUV with a unibody chassis and independent suspension, but it still uses rear-wheel-drive and four-wheel-drive systems and has some off-road capability. It's also a midsize crossover, but only offers two rows of seats. Despite the Grand Cherokee's odd nature, we did come up with a few crossovers and a classic SUV that seem to match the Jeep in size and pricing. We looked at the numbers to compare them on paper. You can find the raw data in the chart below and deeper analysis after that. As always, this is just a comparison of specifications and you'll want to check out our driving impressions of each car if you're getting serious about one or all of these vehicles. And if you want to compare any of these against other vehicles, be sure to check out our comparison tool. Engines and Drivetrains When comparing base engines, the Jeep Grand Cherokee's 295-horsepower is the clear power winner, beating the next most powerful 4Runner by 25. But in torque, the 4Runner takes the laurels with 278 pound-feet, narrowly edging out the Edge's (no pun intended) turbocharged 2.0-liter four-cylinder's 275. That four-cylinder in the Edge will also be picking up another 5 horsepower for 2019, but it still won't win this power contest. Both Ford and Jeep also have another advantage in the fact that you don't have to settle for the base powertrain. Ford has two other engine options, a naturally aspirated V6 and a twin-turbocharged V6, the latter of which outguns the Grand Cherokee's gasoline V6 in both power and torque. That engine will also be bumped up to an impressive 335 horsepower and 385 pound-feet of torque. View 20 Photos The Jeep has the most engine options, though, and it's the only to offer V8 and diesel options. On most Grand Cherokees, the options include a 5.7-liter V8, which is only available with 4WD. It makes 360 horsepower and 390 pound-feet of torque, outperforming even the 2019 Edge's twin-turbo V6. The diesel engine doesn't make much power with just 240, but it makes up for it with torque at 420 pound-feet. And of course there are the SRT and SRT Trackhawk models with even bigger and supercharged V8 engines respectively.
