A look inside Infiniti's variable-compression engine

We're sympathetic to anyone who had trouble understanding what's going on with Infiniti's new variable-compression engine. While we got a full tech briefing on the novel VC-Turbo back in August, the visual aids were lacking. The cutaway engine Infiniti brought to the Paris show fixes all of that. You can thank the little green and pink lines on the cutaway for making the whole idea a little more clear. Click through the gallery to see two lines – one green and one pink – that represent the different strokes allowing for different compression ratios. Remember, the compression ratio is the amount of volume in the cylinder on intake compared to the amount at the end of the compression stroke. Leave more room at the end and you lower that ratio. The length of the stroke doesn't change with this system, but where it sits along the cylinder does. Hence those two lines. The variable compression ratio allows this new turbocharged engine to maximize fuel economy when the turbo isn't needed by raising the compression ratio. It will see its first use in the next Infiniti QX50 crossover, previewed by the QX Sport Inspiration concept that's also on display in Paris, and has performance targets of 268 horsepower and 288 pound-feet of torque. After, it will migrate to other Infiniti and Nissan vehicles, with transverse front-drive-based applications first in line. Eventually, it's likely to completely replace Nissan's corporate 3.5-liter V6. We'll be poking around the engine a little more in Paris today to try and get some more info. For now, enjoy those cutaway images and those friendly little lines.

Infiniti teases Qs Inspiration electrified sedan concept for Auto Shanghai

Infiniti has the third installment of its Q concept lineup ready for Auto Shanghai in a couple of weeks. The 2018 Detroit Auto Show saw the Q Inspiration concept, a slinky pearlescent sports sedan. This year's Detroit show welcomed the QX Inspiration concept, an ivory electric crossover that previewed a future product. The Shanghai debut blends the two with the Qs Inspiration concept, "an electrified sports sedan for the future," that previews a forthcoming product. The Qs Inspiration appears to pick up where the 2018 Q Inspiration left off. We noted last year's show car didn't have visible tailpipes, and we suspected an electric powertrain. That wasn't the case — Infiniti said the brand's VC-Turbo technology powered the four-door. This new Qs Inspiration is built on an "all-new flexible architecture developed specifically for electrified powertrains." That's a curious distinction if by electrified Infiniti means an electrically assisted ICE. If a car needs all the paraphernalia of an ICE drivetrain, where's the electric leap? It must be somewhere, because Infiniti says the Qs Inspiration is as groundbreaking as the Q45 sedan that birthed the brand in 1989. Company boss Christian Meunier said, "Electrification creates a range of new possibilities for sedans," the concept "letting us imagine how this type of car could be reinvigorated and adapted to fit the changing needs and tastes of drivers." The teaser tells us nothing but to expect more white. There will be an "electrified form language" outside, a "minimalist cabin" inside. The dual-zone interior contains a "clutter-free cockpit ... to engage the driver, and a relaxed passenger zone that make the most of the generous interior space." Naturally, there'll be more Japanese "artistry and craftsmanship" than you can process in one sitting. Stay tuned April 16 for the reveal.

Infiniti G37 to live on in showrooms alongside 2014 Q50

Infiniti is preparing to roll out its hotly anticipated 2014 Q50, a car that not only ushers in a new alphanumeric naming strategy, it ostensibly replaces the G37 as the brand's bread-and-butter sport sedan. That will happen, but not in the short-term, as the G37 will continue to be manufactured and sold alongside the Q50, at least for the rest of this year.
Infiniti spokesman Kyle Bazemore has confirmed to Autoblog that a decision is pending on how long to extend the G37 sedan's production run. "We're taking Q50 up a little bit, and that allows us to keep the G Sedan in the lineup... It [Q50] certainly started as a replacement, but it ended up being much more than that." Confusingly, Infiniti has already announced that the Q50 is to start at $37,605 (including $905 destination charge), yet the 2013 G37 is more expensive, starting at $38,255 delivered according to Infiniti's consumer website. Thus, a price drop on the G37 is likely coming in short order.
So why hold on to the older model? With the Q50 launching exclusively with V6 and Hybrid models (a turbo four and diesel are said to be in the cards down the road), Infiniti evidently feels it is risking leaving lower-end sales on the table. "There's a lot of movement with the [BMW] 320i and such, and this allows us a two-tier strategy to compete," says Bazemore. Keeping the G37 on tap at a lower price for fleet sale duty may also serve to protect the Q50 as it establishes itself on the market.
