Infiniti recalls Q50 and Q70 Hybrid models

Infiniti is issuing three separate recalls for its Q50 Hybrid and Q70 Hybrid and M35 Hybrid covering roughly 13,794 vehicles in North America.
The larger campaign listed by the National Highway Traffic Safety Administration covers 5,831 examples of its 2014 Q50 Hybrid (shown above) and 2014 Q70 Hybrid in North America, with 5,412 of those in the US and its territories. According to NHTSA, "due to a software error, the electric motor may stop working while the vehicle is being driven using the electric motor only," creating a "stall-like condition." To fix the fault, the company is reprogramming the motor inverter software, and owners should be contacted in mid-November.
The second recall covers just 890 2014 Q50 Hybrid and 2014 Q70 Hybrid models in North America, with 817 of those residing in the US. It's possible that their transmission housings were damaged during manufacturing, and on affected models, the housing could have a crack that might fracture while driving. Dealers will inspect the transmission and faulty examples will be replaced.

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.

Infiniti spruces up Q70L Bespoke Edition for Shanghai [w/video]

"Luxury" is a relative term. Take the Infiniti Q70, for instance, which most of us would find plenty luxurious. But some buyers – in China especially – wanted more, so Infiniti stretched it out into the Q70L. And now it's revealed the even more luxurious Q70L Bespoke Edition. Revealed for the first time at the Shanghai Motor Show down the coast from the company's global headquarters in Hong Kong, the Infiniti Q70L Bespoke Edition is designed to "fill the gap between the current interiors in production cars and luscious interiors of Infiniti's concept cars." That's been materialized through a quilted white leather cabin space with four individual seats hewn "by meticulous craftsmanship and three-dimensional textures." It all looks pretty swank to us, but not the kind of space you'd want to put your kids in with their juice boxes, crayons and dirty soccer uniforms.

The special version of the production Q70L, with a 5.9-inch (150 mm) longer wheelbase, features four luxurious seats wrapped in rich white quilted leather. This exploration is meant to fill the gap between the current interiors in production cars and luscious interiors of Infiniti's concept cars. Shaped by meticulous craftsmanship and three-dimensional textures, the cabin of the Q70L Bespoke Edition has been transformed into a cossetting space, hinting at how the artistry of Infiniti's concept cars can become reality. The production model of the Infiniti Q70, and two more Infiniti concepts – the Q80 Inspiration and Q60 Concept – were also making Auto Shanghai debuts.
