Nissan reveals radical BladeGlider concept for Tokyo debut

Radical reinvention of the automobile doesn't happen very often. There's a reason they refer to it as "reinventing the wheel", after all. But that's what a team of racecar designers did with the original DeltaWing concept in 2010. Originally proposed as an IndyCar racer, the project was subsequently redesigned for Le Mans. That's when Nissan got on board, supported the project for a few races, then took the design in its own direction with the ZEOD RC. And now it's taking it to the road... via the auto show.
What we have here is the BladeGlider concept, a proposal for a delta-shaped electric sportscar which Nissan will present at the Tokyo Motor Show in a couple of weeks. Designed to focus on driving pleasure, the BladeGlider is about as radical as they come. Like the DeltaWing and ZEOD RC, it's got a narrow front track and wide rear to minimize drag and optimize stability, packing a 1+2 seating arrangement to put the driver front and center like in a McLaren F1, with upward-swinging doors and underbody aerodynamics to keep it glued to the road. In-wheel motors (of unspecified output) provide the power, a lightweight lithium-ion battery (not to mention the carbon-fiber bodywork) keeps it all fearther-like, and weight distribution is heavily biased towards the rear at 30:70.
A radical concept, to be sure, but here's the kicker: Nissan wants to build it. As you can see from the press release below, the BladeGlider "is both a proposal for the future direction of Nissan electric vehicle (EV) development and an exploratory prototype for an upcoming production vehicle". While it would undoubtedly take some time to develop, much less certify for road, seeing one of these - or even better, driving one - on our favorite stretches of tarmac strikes us as a prospect worth waiting for.

Feds arrest two men accused of smuggling Carlos Ghosn out of Japan in a box

Authorities say this Dec. 30, 2019, image from security camera video shows Michael Taylor, center, and George-Antoine Zayek at passport control at Istanbul Airport in Turkey.

Chairman Carlos Ghosn out of Japan in a box while he awaited trial there on financial misconduct charges. Michael Taylor, a 59-year-old former Green Beret and private security specialist, and Peter Taylor, 27, are wanted by Japan on charges they helped Ghosn escape the country in December after he was released on bail. The men were arrested by the U.S. Marshals Service in Harvard and were expected to appear before a judge via videoconference later Wednesday. The tale of the daring escape began on Dec. 28, 2019, when Peter Taylor arrived in Japan and met with Ghosn at the Grand Hyatt Tokyo for about an hour, authorities said. Just before 10 a.m. the next day, Michael Taylor flew into Osaka, Japan, on a chartered Bombardier Global Express jet from Dubai with another man, George-Antoine Zayek, carrying two large black boxes with them. The elder Taylor was experienced with sticky situations. Over the years, he has been hired by parents to rescue abducted children, gone undercover for the FBI in a sting on a Massachusetts drug gang and worked as a contractor for the U.S. military in Iraq and Afghanistan. The last assignment had landed him in a Utah jail for 14 months, caught in a federal contract fraud case that upended TaylorÂ’s family and finances before he agreed to plead guilty to two charges. It's not clear yet how Ghosn hooked up with Taylor. At their arrival, Taylor and Zayek, his Lebanese-born colleague, told airport employees they were musicians carrying audio equipment. Meanwhile, Ghosn, who was out of custody on a hefty bail, headed to the Grand Hyatt in Tokyo and met up with Peter Taylor in his hotel room, authorities said. The elder Taylor and Zayek joined after a brief stop to rent a separate room near the airport. And soon after their arrival, the group left the Grand Hyatt and split up.

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.
