Nissan Note getting a little louder with Nismo versions this fall

Nissan's Nismo performance division has been getting more chances to shine recently with tuned models like the Juke Nismo RS and GT-R Nismo. But its latest creation moves closer to the bottom of the Japanese brand's lineup to make a hot hatch out of the (Versa) Note. At least in Japan, the new model is due this fall, and Nismo is keeping a lot of the details about its latest creation a secret for now. What we do know is that it'll be available in two trims – the Note Nismo and the sportier Nismo S. "The development concept of this model was to build a car that makes you want to keep driving, no matter where your destination may be," said the division's chief product specialist, Hiroshi Tamura, in the company's announcement. Aesthetically, the Note Nismo looks the way a tuned Nissan should, with the division's signature red trim outlining the car. It also wears a new, mesh grille, lower air dam, red side sills and rear spoiler. Inside, the S gets standard sport seats with full Recaro buckets as an option. Nissan didn't release technical specs for either version, but it promises that the S also gets a tuned engine with a five-speed manual. But now, allow us to burst your bubble. Autoblog spoke to Nissan North America Product Communications Director Dan Bedore about the hot Note, and he told us, "There are no plans currently for a Nismo Versa Note in the US." That's too bad; if the specs turn out to be competitive, it could be an interesting rival for the Ford Fiesta ST. Scroll down to read the official announcement. NISSAN UNVEILS THE NOTE NISMO, SCHEDULED TO GO ON SALE IN FALL 2014 YOKOHAMA, Japan (July 23, 2014) – Nissan Motor Co., Ltd. has taken the veils off the latest and sportiest iteration of the popular Note, called Note Nismo, which will reach dealer showrooms in the fall of 2014. Nissan also announced that the Fairlady Nismo will receive a minor model change, while a new Nismo RS grade will be added to the Juke Nismo in the fall of 2014. Ever since the release of the Juke Nismo in February 2013, the lineup of Nissan's specialty division, Nismo, has steadily grown. Soon after the launch of the Juke Nismo, the March Nismo, Fairlady Nismo and Nissan GT-R Nismo were added to the stable; thus allowing Nismo to offer a broad range of road-going cars to the public-from compacts to SUVs to sports cars-all armed with the sporty DNA derived from Nismo's motorsports activities. And now you can add one more to the list, the Note Nismo.

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.

Nissan BladeGlider Concept shows its inner DeltaWing

Just like the DeltaWing and ZEOD RC racecars, it takes seeing the Nissan BladeGlider concept live to get a true appreciation for its design. But that doesn't mean it's any less weird. The wedge-shaped, three-seat concept car hit the stage today at the Tokyo Motor Show, and Nissan says the car is an "exploratory prototype" for a future production model.
The BladeGlider is defined by its design with front wheels that are just about three feet apart, while the rear has a more conventional track. Opening the scissor doors reveals a center driving position flanked by two passenger seats with a cockpit-inspired design. Although no power figures were revealed for the conceptual vehicle, Nissan does say that the BladeGlider is an all-electric vehicle with its battery pack mounted toward the rear of the car helping to provide a 30/70 weight distribution front to rear.
