Infiniti EV coming in 2021

Infiniti announced that it will offer new electrified vehicles starting in 2021. Nissan CEO Hiroto Saikawa said that its luxury brand will build its first all-electric car in 2021, as well as new "e-Power" vehicles – series hybrids with batteries charged by gasoline generators. Nissan has introduced e-Power vehicles in other markets, including the Note e-Power and the Serena e-Power minivan. Now it will extend that technology to Infiniti, providing a similar driving experience to an EV with the convenience of a gas-powered vehicle. Infiniti also said that we can expect "beautiful vehicles" like the Q Inspiration Concept that debuted at the 2018 Detroit Auto Show. Infiniti doesn't plan on producing the Q Inspiration, but it will certainly influence future vehicles in terms of both styling and technology. The Q Inspiration uses variable compression technology, which the company intends to use to improve efficiency and performance of its gasoline-powered cars. Infiniti expects half of its global sales to be electric vehicles by 2025 (it's not clear whether the automaker is lumping series hybrids into the electric vehicle category). And while there's no way that Infiniti will release a production version of its all-electric Prototype 9 EV, seen above, we'll hold onto that dream anyway.

Nissan Murano hybrid greens up Shanghai

Nothing says summertime like a muscle car with a ragtop. Or, in China's case, a hybrid crossover SUV, right? So it's a good thing Nissan plans on starting sales of a hybrid variant of its Murano in China for the upcoming warm weather season. Nissan showed off the Murano Hybrid at the Shanghai Motor Show with a supercharged engine that is paired with an electric motor. The company says the powertrain will deliver the fuel economy of a 2.0-liter engine and the power of a 3.5-liter V6 engine. Nissan didn't release actual specs of the engine nor any fuel-economy figures. Back in 2013, Nissan was working on expanding its hybrid choices, including hybrid variants for both the Murano and the Rogue. This powertrain choice makes some sense, since it could be difficult to wring a decent single-charge range out of those relatively heavier vehicles if they were all-electric. With that in mind, take a look at Nissan's press release below. NISSAN APPEALS TO CHINESE WITH TWO WORLD PREMIERES: LANNIA AND MURANO HYBRID AT AUTO SHANGHAI 2015 Lannia makes global debut to capture the hearts of young Chinese customers All-new Murano Hybrid offers excellent fuel economy and driving performance in the luxury SUV segment Customers in China can begin ordering GT-R Nismo and 370Z Nismo today SHANGHAI, China (April 20, 2015) – Nissan unveiled two all-new production models, Lannia and Murano Hybrid, along with two Nismo products, GT-R Nismo and 370Z Nismo, at Auto Shanghai 2015. "These innovative vehicles represent the start of an exciting new chapter in the story of Nissan's presence in, and commitment to, China," said Nissan President and CEO Carlos Ghosn. "Nissan's growth strategy in China will continue to reflect our commitment to use local engineering and manufacturing. And we will maintain our support for China's efforts to promote more efficient and sustainable transportation. On both of these fronts, Lannia and Murano Hybrid will lead the way forward." Highlights of the Nissan display: Building on Nissan's longstanding success in the sedan market, Lannia delivers a fresh, distinctive personality that China's young generations embody. As the first product developed and designed for the young Chinese generations, especially those in their 20s and 30s today who are seen as energetic trendsetters, Lannia is a tangible expression of the company's commitment to China.

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.
