Nismo mashes it up with Sentra 370Z and Altima GT-R

Nismo was a tuning division once content (or required) to restrict itself to just one or two models at a time, but these days Nissan is taking the gloves off and allowing its motorsport department to tune just about everything's it's got.
Now in its thirtieth year, Nismo tunes versions of the GT-R, 370Z, Juke and Versa Note, and will soon be working its magic on the Sentra and European-market Qashqai and Pulsar. And that's not even taking into account its considerable racing programs. At this rate, Nismo is going to run out of vehicles to tune pretty quickly, so what has it done? Invent new ones!
No, we're afraid that Nissan is not letting its Nismo division produce its own stand-alone product, but it has released two sets of amusing renderings combining two vehicles into one. One depicts a GT-R crossed with a Teana sedan (better known in these parts at the Altima), while the other crosses a Sentra with a 370Z.

World's Strongest Man champion pulls a dozen Nissan Note hatchbacks to set record

On December 1, Zydrunas Savickas, a five-time World's Strongest Man champion, pulled 12 Nissan Notes (the equivalent to our Versa Note) weighing 28,530 pounds over 16.4 feet in 32.9 seconds. The feat, performed in Lithuania at the end of the country's Car of the Year test camp, was enough to secure him the Guinness world record for "Most Cars Pulled By One Man."
"Once I got into my stride pulling the 12 Nissan Notes, [it] was fine," Savickas said after the pull. "Obviously, a big thank you to Nissan for helping me set the record and making it all happen."
"We at Nissan like setting records and are always aiming high," said Taina Erkkilä, Communication Director of Nissan Nordic Europe. "Today we are delighted to have been able to help Zydrunas set another world record and see so many people turn out to support him."

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.
