2015 Nissan GT-R Nismo priced from $149,990* [w/videos]

Remember when they called the Nissan GT-R a supercar-slayer? You can drop the "slayer" part, because the Japanese brute known as Godzilla has long since grown from an ankle-biter nipping at the heels of giants to a giant in its own right. And if that's the case with the "basic" GT-R, it's certainly the case with the new GT-R Nismo.
While the base price for the GT-R has breached the six-figure mark, the Nismo version has just been priced ten bucks shy of $150k. Factor in the $1,595 destination charge and you're looking at a $151,585 sticker price. That may seem like a lot for a Nissan, but bear in mind what you're getting for all that scrap: the GT-R Nismo's 3.8-liter twin-turbo V6 has been optimized to deliver 600 horsepower and 481 pound-feet of torque to all four wheels.
We've yet to see official performance stats, but considering that the base GT-R hits 60 in 2.6 seconds with 55 hp and 18 lb-ft less muscle, the Nismo version ought to teach a lesson or two to exotic supercars costing twice or even ten times as much. Just check it out in the videos and press release below.

Nismo smartwatch concept tracks both car and driver [w/videos]

Whether you agree or not, this writer believes that every supercar needs a wristwatch to go with it. Though the Nissan GT-R has been lacking in this one regard, Nissan is keen to correct that wrong. But while most of these automotive-inspired timepieces are decidedly mechanical, Nissan has gone a suitably different direction in creating its new Nismo watch concept.
The electronic smartwatch connects driver, car, watch and phone in a sleek design. The device allows drivers to monitor such parameters as the car's average speed and fuel consumption, access performance telematics on the track, monitor their own heart rate and interface with their smartphone via Bluetooth and a dedicated app. The watch can even tell the driver when it's time to bring his car in for scheduled maintenance, post lap times and such to popular social media platforms, and of course, you know - literally give you the time of day.
Though still in the concept phase, Nissan seems keen to bring this to market, has even gone so far as to design the packaging - made of tire rubber scraped off the track - and done it up in three colors: red, white or black. In the meantime Nismo will be showcasing the smartwatch concept at the Frankfurt show this week, where we hope to get a glimpse up close, but you can delve into the press release and the pair of videos below.

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.
