Mitsubishi and Renault-Nissan expand partnership, US will get new sedan

Mitsubishi and Renault-Nissan have just inked an alliance that might, hopefully, reverse the ailing fortunes of the Mitsubishi brand in the US market. The big chunk of news is that Mitsubishi will produce two Renualt-based models for sale in the US market, and that they'll be built at the Renault-Samsung factory in Busan, South Korea.
The plans call for a D-segment sedan to be followed by a C-segment offering. Based on the cars built at the Busan factory, that means Mitsubishi will be getting the SM5 and the SM3, a pair of handsome sedans that are based on Renault-Nissan's D and C platforms, respectively. These same platforms underpin a number of US market Nissans (not to mention a number of cars from Renault), namely the Pathfinder, Maxima, Quest and Murano for the D platform and the last-generation Rogue and Sentra for the C platform.
Besides the sedan production, Nissan and Mitsubishi will be expanding their joint-venture company, NMKV, which produces Kei cars for the Japanese market. A new, all-electric offering will be born from the partnership, likely based on a Kei car platform. The partnership between the three brands will also lead to increased sharing of technology, particularly relating to electric cars.

Ghosn's first jail interview: I was the victim of 'plot and treason'

TOKYO — Carlos Ghosn said Nissan executives opposed to his plans for closer ties with automaking partner Renault SA resorted to "plot and treason" to disrupt them and were behind the financial misconduct allegations against him. Speaking to the Nikkei newspaper in his first media interview since his arrest on Nov. 19, Ghosn said he had discussed plans to integrate the companies with Nissan CEO Hiroto Saikawa in September. But Nissan executives employed "plot and treason" to uproot those plans, Ghosn said. 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, despite strong reservations at the Japanese corporation. He remains in detention following his arrest and indictment on charges related to breach of trust and understating his salary. His arrest has clouded the outlook for closer ties between Nissan and Renault, along with Mitsubishi Motors Corp, the third member of the automaking alliance Since his arrest, Saikawa has said it was not the time to discuss revising the partners' complex capital ties. Nissan and Mitsubishi Motors have dismissed Ghosn as chairman, while he has resigned from the helm at Renault. Ghosn denied accusations of improper payments to a company run by a Saudi businessman, saying the payment had been approved by a Nissan executive. Ghosn also called accusations by both Nissan and Mitsubishi that he received nearly 8 million euros in improper payment through a Dutch-based joint venture of the two automakers "a distortion of reality," and argued his luxury residences in Rio de Janeiro and Beirut were approved by Nissan's legal department. Nissan has said it was not aware that it had paid for many of Ghosn's properties. On Wednesday, a spokesman said that the company was unable to comment on Ghosn's legal defense. Ghosn, in the 20-minute interview, denied that his tenure at Nissan had been a "dictatorship." "People translated strong leadership to dictator, to distort reality" for the "purpose of getting rid of me," he said. Ghosn added that his health was fine, and that he wouldn't flee if freed on bail. Meanwhile, NHK reported that Saikawa plans to hold his first face-to-face discussion with new Renault Chairman Jean-Dominique Senard on the sidelines of an alliance meeting in the Netherlands on Thursday.Related Video: This content is hosted by a third party.

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.
