Nissan applies for 'R-Hybrid' trademark, but what is it for?

Patent and trademark filings are sort of like tasseography for those of us in the auto industry. If you know where and how to look at something, there's a lot to be figured out. Take this trademark filing from Nissan - it's similar to the Pure Drive badge found on a Versa or Sentra, but the bottom half sports the phrase "R-Hybrid." This wouldn't be remarkable if the "R" in R-Hybrid weren't the same style as the "R" in the Nissan GT-R's badge, right down to the serifs.
While it's easy to see this as grasping at straws, it makes a fair degree of sense. The R35 GT-R may be a dominant performance machine, but it's been around since 2008, which is donkey years in the automotive industry. And based on the recent crop of hybridized hypercars and racecars, a hybrid GT-R doesn't seem like such a stretch.
As Car And Driver points out, figuring out that the GT-R will go hybrid isn't hard - figuring out when it will arrive, is. The buff book rightly points out that a new GT-R isn't expected until 2017, but that designing and trademarking a badge four years ahead of time is a bit odd. Car and Driver speculates that we could see a mildly hybridized R35, although the chances do seem remarkably low. Head over to C/D for a more thorough rundown on why this just might be a GT-R badge, including comparisons with other R-badged Nissans.

2015 Nissan Leaf gets B mode standard, new MorningSky Blue color

The Nissan Leaf is getting a few updates for the 2015 model year, some functional, some purely aesthetic. The appearance options will be made available later than the rest, and include a new exterior color called MorningSky Blue, as well as standard 17-inch aluminum alloy wheels for the SV trim level. In terms of driving, the 2015 Leaf gets a dedicated B-mode for every trim level, including the base S car (it was formerly only available in the SV and SL levels). This provides more aggressive regenerative braking when the driver is not on the accelerator - perfect for making the most of those downhill grades. Now every Nissan Leaf includes Normal, Eco-Mode and B-Mode, regardless of trim level. SV and SL trim levels also get a couple new convenience features. For those who find it impossible to disconnect while driving, the Hands-Free Text Messaging Assistant allows them to communicate without taking their eyes off the road, taking their hands off the wheel or risking a distracted driving ticket (perhaps you might want to rethink using it, though). Additionally, SV and SL customers will Voice Destination Entry to make spontaneous rerouting to the theme park a little easier. Of course, a lot of other Nissan cars got some cool upgrades this year. The Quest, NV200 Compact Cargo and V6-powered Altima, for instance, eke out another mile per gallon highway and combined. See what's new in the Leaf and the rest of the Nissan lineup in the press release below. The 2015 Nissan Lineup: Charting the Changes Nissan's U.S. sales have significantly outperformed the industry in 2014, up 12.7 percent CYTD through June. Sales have been led by the recently redesigned Altima, Rogue and Sentra – along with other models such as LEAF (+29.4%), JUKE (+44.9%), Frontier (+22.6%) and NV200 (+439.3%), which have shown strong results month after month. This gives the Nissan lineup great momentum heading into the 2015 model year. Headlining the changes for 2015 is the upcoming launch of the all-new Nissan Murano (due in late 2014). As the halo vehicle for Nissan's expanding range of bold crossovers and SUVs, the dramatic 2015 Murano features a new V-motion front end, LED boomerang lights and a unique "floating" roof. Murano's breakthrough exterior design carries into the interior, which offers an engaging social lounge feel through features such as advanced NASA-inspired Zero Gravity front and outboard rear seating and oversized Power Panoramic Moonroof.

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.
