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.

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.

Major automakers post mixed US June sales figures

General Motors, Ford and Fiat Chrysler Automobiles NV posted declines in US new vehicle sales for June on Monday, while major Japanese automakers reported stronger figures. Once again, demand for pickup trucks and crossovers offset a decline in sedan sales. Automakers' shares rose as overall industry sales still came in above Wall Street expectations. The US auto industry is bracing for a downturn after hitting a record 17.55 million new vehicles sold in 2016. Analysts had predicted that overall, US vehicle sales would fall in June for the fourth consecutive month. As the market has shown signs of cooling, automakers have hiked discounts and loosened lending terms. Car shopping website Edmunds said on Monday the average length of a car loan reached an all-time high of 69.3 months in June. "It's financially risky, leaving borrowers exposed to being upside down on their vehicles for a large chunk of their loans," said Jessica Caldwell, Edmunds' executive director of industry analysis. GM said its sales fell about 5 percent versus June 2016, but that the industry would see stronger sales in the second half of 2017 versus the first half. "Under the current economic conditions, we anticipate US retail vehicle sales will remain strong for the foreseeable future." GM shares were up 2.4 percent in morning trading, while Ford rose 3.3 percent and FCA shares jumped 6 percent. "US total sales are moderating due to an industry-wide pullback in daily rental sales, but key US economic fundamentals clearly remain positive," said GM chief economist Mustafa Mohatarem. "Under the current economic conditions, we anticipate US retail vehicle sales will remain strong for the foreseeable future." Ford said its sales for June were hit by lower fleet sales to rental agencies, businesses, and government entities, which fell 13.9 percent, while sales to consumers were flat. But it sold a record 406,464 SUVs in the first half of the year, with Explorer sales increasing 23 percent in June. And sales of the F-150 had their strongest June since 2001. On a media call, Ford executives said an initial read of automakers' sales figures indicated a seasonally adjusted annualized rate of around 17 million new vehicles for the month, which would be better than 16.6 million units analysts had predicted. FCA said June sales decreased 7 percent versus the same month a year earlier.
