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.

Tesla exec calls rival EVs 'little more than appliances'

Tesla's Vice President of Business Development Diarmuid O'Connell called the company's competition "little more than appliances" at the Center for Automotive Research's Management Briefing Seminars in Traverse City, MI yesterday. "In essence, [mainstream automakers] delivered little more than appliances," O' Connell said. "Now, appliances are useful. But they tend to be white. They tend to be unemotional." According to Automotive News, O'Connell's main critique is that vehicles like the Nissan Leaf and BMW i3 don't deliver enough performance or range to draw the attention of consumers outside of a small group. The solution, in O'Connell's mind, is more power, more range, more excitement and a lower price – that last point is particularly rich coming from an automaker whose cheapest current offering, the Model S 60, costs $66,000 – although the cheaper Model 3 is on the horizon, way out there, somewhere. But some EVs are better than none, O'Connell added. "On balance, I'm happier that [traditional automakers are] doing these cars than not," O'Connell said. "I just wish they would do them better and faster." O'Connell also used his appearance at the Management Briefing Seminars to launch a volley at the Michigan legislature, blaming its opposition to Tesla's direct-sales model for the lack of available EVs in the Wolverine State. "I think if the Michigan Legislature would allow Tesla to sell cars in Michigan, we could probably address [the lack of available electric cars]," O'Connell said. Related Video:

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.
