Carlos Ghosn appears in court: 'I am wrongly accused'

TOKYO — Former Nissan Chairman Carlos Ghosn told a Tokyo court on Tuesday that he was innocent, defending his honor in his first public appearance since he was arrested on Nov. 19 and charged with false financial reporting. "Your honor, I am innocent of the accusations against me," Ghosn told the judge, speaking firmly and calmly as he read from a statement. "I am wrongfully accused." Prosecutors have charged Ghosn, who led a dramatic turnaround at the Japanese automaker over the past two decades, with falsifying financial reports in underreporting his income by about 5 billion yen ($44 million) over five years through 2015. They also say he is suspected of having Nissan temporarily take on his investment losses from the financial crisis. Seen for the first time since his November arrest, Ghosn was wearing a dark suit without a tie, and plastic slippers, and looked thinner and with gray hair. He rebutted the allegations against him point-by-point and said he had the option to leave Nissan but had decided to stay on. "A captain doesn't jump ship during a storm," he told the court in a strong voice. The veteran auto executive, a familiar face at the World Economic Forum and other elite gatherings, was handcuffed and led into the courtroom with a rope around his waist as the hearing began. Officers uncuffed him and seated him on a bench. Presiding judge Yuichi Tada then read out the charges and said Ghosn, a Brazilian-born Frenchman of Lebanese ancestry, was considered a flight risk — he was arrested on his arrival in Tokyo by private jet — and might try to hide evidence. In Japan, suspects are routinely held without bail, often due to fears about evidence tampering. During Tuesday's hearing, Go Kondo, one of Ghosn's lawyers, argued he was not a flight risk. "He's widely known so it's difficult for him to escape. There is no risk that the suspect will destroy evidence," he said. Facing the courtroom, Ghosn spoke proudly of the automaker's — and his own — achievements, such as reviving iconic models like the GT-R and the Z, expanding operations in China, Russia, Brazil and India and pioneering electric cars and autonomous driving. "I have a genuine love and appreciation for Nissan," he said. Ghosn has been held in spartan conditions at a Tokyo detention facility since he was taken into custody. In keeping with Japanese regulations, he has been allowed visits only from his lawyers and consular officials.

Nissan GT-R and Ferrari 458 Speciale in track battle by Evo

Supercar slayer. That's what they call the Nissan GT-R. And in many ways it is, even though its price and performance over the years have risen to put it squarely in supercar territory of its own right.
In fact, as Evo magazine has been compiling a list of its fastest cars - using the Anglesey Circuit in Wales as its common ground - the GT-R has came out on top... that is, until Evo tested the Ferrari 458 Speciale. The two are about as different as you can get within the supercar segment: one has a turbo six up front driving all four wheels in a 2+2 configuration, the other a mid-engined, rear-drive V8 two-seater. In fact the only common ground you're likely to find between them comes down to their two doors and dual-clutch transmissions. Though they serve it up in different ways, both are class-leading performers.
We're looking forward to watching Evo populate its leaderboard with more entries like the McLaren 650S and more potent Nismo GT-R, but in the meantime the British enthusiast magazine, by popular demand, has released side-by-side in-car footage of both supercars putting their best lap forward around the seaside circuit.

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.
