Nissan, least profitable Japanese automaker in Q3, stays strong on EVs

Nissan had some not-so-good financial news to report today. Despite a 57-percent net income increase, Nissan was Japan's least-profitable carmaker for the third quarter of last year. A weak yen helped put the company's operating profit below the estimates of financial analysts. In a speech on the financial situation, Nissan corporate vice president Joji Tagawa said "These results, however, do not reflect the full potential of Nissan." Given our focus on expensive electric vehicles, among other things, we wondered how this might affect EVs. One of the financial analysts told Bloomberg that the news is a "crisis" at the company, but the official word is that things are steady as she goes on the EV front. In his speech, Tagawa reaffirmed the company's strong belief in plug-in vehicles, saying that "Nissan's EV strategy will accelerate with the launch in fiscal 2014 of the e-NV200, the second all-electric model available globally." That electric van has the potential "to transform emissions among commercial vehicles" and Nissan remains interested in initiatives such as EV carsharing in Japan and the continued deployment of charging infrastructure. The speech transcript is available below. In a statement to AutoblogGreen, Billy Hayes, Nissan's vice president and program director, said that, "Nissan considers zero emission vehicles to be the ultimate solution for realizing sustainable mobility in the future and is strongly committed to EV technologies. Nissan's investment in Leaf and EV technology is positive for the company's business results over the lifecycle, and accelerating sales of Leaf only help to build economies of scale and improve the business model for the technology further." FY13 3Q financial results Nissan Motor Co., Ltd. Joji Tagawa, Corporate Vice President Introduction For the nine-month period, Nissan has made solid progress to improve its business performance. The pro forma nine-month financial results, and particularly those of the third quarter, are up compared to the same period last year, despite intense competition and uncertain economic conditions. These results, however, do not reflect the full potential of Nissan. Looking ahead to the quarter ending March 31, 2014, we expect to continue to improve our business results and as such, we are maintaining our prior profit outlook for the fiscal year.

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.

Nissan EV design is diverging in three directions

As the movie awards season kicks into high gear, Nissan design chief Shiro Nakamura appears to be implying that his company's electric-vehicle design prospects are about to go from Philomena into The Wolf of Wall Street territory. Nakamura, speaking with Motor Authority at the Detroit Auto Show last week, allowed that the design of the five-seat Nissan Leaf is fairly conservative and will remain so given that the model continues to be the most practically-minded EV from the company. In the near future, though, Nissan is planning to head in different directions. Specifically, an all-electric sports car and a two-seat commuter vehicle that could come with in-wheel electric motors that will allow the designs to get more radical. How radical? Well, we've heard Nissan may bring the BladeGlider concept (pictured) it unveiled at the Tokyo Motor Show late last year to production. It has a narrow front and wider rear and a 1+2 seating arrangement. Beyond that, Nissan has the two-seat Esflow concept vehicle it showed off in 2011 that could provide some hints, since it's expected that some of the design components from that car will be worked into the upcoming production models.
