2014 Nissan Serena offers big flexibility in a tidy package

In America, Nissan attempts to slake our kinschlepping needs with its slow-selling Quest minivan, but in Japan, where consumers seem a lot less reluctant to buy MPVs, there are a lot more models for every size family and budget. Nissan itself offers no fewer than six such minivans, including the popular Serena seen here.
Technically a mid-cycle facelift, this new Serena continues to offer seating for up to eight people with a gas-only or mild hybrid driveline delivering power to either the front or all four wheels. This Tokyo Motor Show reveal takes that familiar package and lends it a freshened look, complete with a revamped front fascia with less chrome frosting, optional LED headlamps, new LED taillamps and new alloy wheel patterns. In addition, the Serena receives new active safety technology, including lane departure warning systems, Around View Monitor with Moving Option Detection, Driver Attention Alert, and so on.
With only a 2.0-liter four-cylinder engine paired with a continuously variable transmission, you might expect the Serena to be smaller than today's American minivans, and you'd be right - it's roughly the size of a short-wheelbase Gen III Dodge Caravan, making its seating capacity particularly impressive. Said another way, the Serena is likely to stay forbidden fruit, but that doesn't mean you can't enjoy it in our gallery.

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.

Carlos Ghosn's lawyer requests bail again after Nissan ex-chairman indicted — again

TOKYO — Japanese prosecutors indicted Carlos Ghosn on Monday on another charge of aggravated breach of trust, a Tokyo court said, the fourth charge against the former Nissan Motor Co Ltd chairman, which his lawyers met immediately with a bail request. The charge came on the day Ghosn's latest detention period was set to expire. Ghosn had been out on bail when authorities arrested him for a fourth time on April 4 on suspicion he enriched himself at a cost of $5 million to the automaker. "We are confident that we have the evidence to successfully prosecute all four cases," an official from the prosecutor's office said at a briefing after the indictment was announced. Ghosn has denied all four of the charges, which include understating his income, and said he is the victim of a boardroom coup. He has accused former colleagues of "backstabbing," describing them as selfish rivals bent on derailing a closer alliance between Nissan and its top shareholder, France's Renault SA. "Carlos Ghosn is innocent of the latest charges brought against him by the Tokyo prosecutors, aided and abetted by certain Nissan conspirators," a Ghosn representative said in a statement. The case has exposed tensions in the Nissan-Renault alliance forged by Ghosn some two decades ago when the French automaker invested in Nissan, then on the brink of bankruptcy — a deal that gave Renault control over its larger partner. Nissan is due to reject a management integration proposal from Renault and will instead call for an equal capital relationship, the Nikkei newspaper said on Monday, citing sources. Ghosn's arrest has also focused a harsh light on Japan's judicial system, which critics refer to as "hostage justice" as defendants who deny their charges are often not granted bail. Under Japanese law, prosecutors are able to hold suspects for up to 22 days without charge and interrogate them without their lawyers present. In accordance with these terms, prosecutors had to indict or release Ghosn by Monday. According to the latest indictment, Ghosn caused a total of $5 million in losses to Nissan from July 2017 through July 2018. During that period, prosecutors allege two separate payments of $5 million were made from the account of a Nissan subsidiary into the account of an overseas dealership. A total of $5 million was subsequently transferred from the dealership's account to another account in which Ghosn had an interest.
