Infiniti G37 to live through MY 2015, sell alongside Q50

Infiniti has officially confirmed news we broke last month about its G37 sedan - that it will live on in showrooms alongside its erstwhile replacement, the 2014 Infiniti Q50, a model that goes on sale this week. And it's sticking around for quite a while - it will be sold through the 2015 model year.
In order for the G37 and Q50 to not rub shoulders, Infiniti is rolling out an amended G lineup, complete with lowered pricing. The G37 will stick around in Journey and all-wheel drive trims, both powered by the same 3.7-liter VQ-Series V6 engine, and only two option groups will be available, Premium and Navigation. The 2014 G37 Journey will start at $32,550, while the G37 Sedan AWD will run $34,150 (both are subject to a $905 destination fee).
The 2013 G37 had been priced from $38,255 delivered as of earlier this week, so the price drop is significant, likely bringing the base MSRP more in line with where transaction prices had been on the aging model. The new pricing, which takes effect August 6, should also allow the G37 gain consideration amongst shoppers of smaller-engined rivals like the BMW 320i while the Q50 waits on a turbocharged four-cylinder and diesel engine from Daimler. For comparison's sake, the larger, more tech-rich Q50 will start at $37,605 delivered.

Infiniti puts EV plans on hold again

Think of it as the green-automotive industry's version of Groundhog Day. Nissan's Infiniti division is putting plans for its first mass-production electric vehicle on hold. Again. The Infiniti LE, whose concept version was unveiled 2012's New York Auto Show, is again being put up on the proverbial blocks, USA Today says, citing a presentation by Infiniti executive Michael Bartsch at a recent company event in Detroit. Essentially, the Nissan division has bigger fish to fry, in the form of boosting overall Infiniti sales, and doesn't yet want to put the effort into introducing the Infiniti LE. The Infiniti EV plans were first postponed by then-Infiniti President Johan de Nysschen during the summer of 2013, as de Nysschen wasn't quite buying into Nissan boss Carlos Ghosn's ambitious electric vehicle sales projections. De Nysschen resigned last summer to join General Motors' Cadillac division. One issue may be the fact that the Infiniti wouldn't be all that different from the Nissan Leaf. Despite the fact that US sales of that EV surged 34 percent last year compared to 2013, to 30,200 vehicles, an Infiniti version was apparently not enough of a selling point within the company. While the Infiniti is sportier looking than the Leaf and would boast inductive, wireless charging, it would have a similar power output and single-charge range as the Leaf.

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.
