Infiniti to launch first electric car, to be made in China

BEIJING — The first electric car for Nissan's premium brand Infiniti will be a sporty sedan produced in China, the Japanese carmaker said in a statement viewed by Reuters ahead of a public announcement expected as soon as Wednesday. The vehicle would hit the market in around three years, and consumers would get a taste when the company unveils a concept car, dubbed the Qs Inspiration electric sedan, at the Shanghai auto show later this week, Nissan officials said. "China has the most growth potential for electric vehicles globally, especially in the premium segment," Infiniti Chairman Christian Meunier said in the statement seen by Reuters. Automakers operating in China have to sell more so-called new-energy vehicles, either battery electric cars or plug-in electric hybrids, to comply with official production quotas designed to reduce smog. It was not immediately clear whether Infiniti planned to produce its first electric vehicle in other markets. An Infiniti spokesman said, however, the brand did not intend to export the e-sedan from China. The planned e-sedan is part of Infiniti's longer-term strategy to significantly electrify its product lineup. Brand officials have said that from 2021 every Infiniti model launched will be either an all-electric car or so-called "e-Power" hybrids, underlining Nissan's previously announced plan to make Infiniti primarily an electrified offering. The sedan likely would be built on a new flexible architecture developed specifically to accommodate electrified powertrains, Infiniti said in the statement. Its design, especially the interior, would be significantly different than current models, design chief Karim Habib said. EVs do not have bulky gasoline engines and transmissions, opening up space inside the car. "It will have a flat floor, and if you are a passenger you can cross your legs or stretch out your legs," Habib told Reuters. Competition in China's rapidly emerging electric car market is heating up amid an onslaught of models from startups such as Nio and WM Motor, as well as those from established automakers. In the luxury segment, Infiniti will be competing with Tesla Model S and Model X, as well as other models due to be launched in coming months by Audi, Mercedes-Benz, BMW and Lexus.

2016 Infiniti QX50 is new and improved, kind of [w/video]

The Infiniti QX50 is, to be frank, ancient. It hit the market way back in 2007, and has labored on ever since. Through December of last year, the company only moved 2,727 QX50s. The year before, there were only 2,164 sales, and 3,495 in 2012. What do all three years have in common? The QX50 was Infiniti's slowest seller in each of them. Here's hoping, then, that this latest update will boost the 2+2 crossover's appeal. Being shown today at the 2015 New York International Auto Show, Infiniti has made a number of updates to its smallest crossover, with the most notable being a 3.2-inch stretch in its wheelbase and a 4.5-inch increase in its overall length. That makes for an enormous 4.3-inch increase in the legroom of the formerly cramped second row. Infiniti also made slight increases to the overall ride height, of 0.4 inches in for rear-drivers and 0.8 inches for all-wheel-drive variants. Outside of the dimensional changes, Infiniti also beefed up the former EX37's exterior, with new front and rear bumpers that boast SUV-like scuff plating, as well as LED accents in the new headlights and a new grille that is more in keeping with the brand's current design language. LED taillights sit out back as standard, while Infiniti will happily sell consumers an optional xenon headlight package. Infiniti may have updated the exterior, but the cabin looks largely unchanged, aside from the extra space in the second row. It looks like a complete carryover in terms of features, trim and general layout. Also unchanged is the QX50's 3.7-liter V6 engine. Output remains fixed at 325 ponies and 267 pound-feet of torque. Regardless of whether power goes to the rear or to all four wheels, a seven-speed automatic is in charge of managing the power. We'll have more on the freshened QX50, including live images, coming soon from the floor of the 2015 New York Auto Show.

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.
