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.

2019 Infiniti QX50 gets fancy-pants Autograph interior

The 2019 Infiniti QX50 has primarily garnered attention around car enthusiast circles for its variable compression engine. It's a marvel of engineering that uniquely changes its compression ratio to maximize power and fuel efficiency. It can also switch between Atkinson and regular combustion cycles, utilize multi-point or direct injection, it's turbocharged, and even features an electric motor that controls the variable compression ratio. Nifty stuff, but it seems likely that all that technobabble will make the average buyer of Infiniti's new compact SUV go crosseyed. It may not even be mentioned. "It has an engine? Great, let me see the inside." Well, dear car shopper who doesn't give a hoot about the greasy bits, have we got a bit of QX50 news for you. Infiniti has announced the QX50 Autograph package, a special $2,000 option with a seriously upgraded interior. Fancier materials and unique color schemes were selected, drawing inspiration from luxury beach resorts and being awfully similar to those found in the latest Pantone Fashion Color Trend Report. It's probably best to turn things over to the press release at this point. "Starting with warmer color tones, the rich chocolate brown replicates wood applications in the (beach) resort and the surrounding trees, followed by a creamy off-white representing the sand on a beach. The highlights of a cooler dark navy blue on the center console, reminiscent of ocean water, strike the proper balance between warm and cool, creating a comfortable, yet invigorating environment." Have you gone crosseyed? Well, now you know how it feels when describing the greasy bits to a non car person. Those cream, brown and blue bits are the Pantone colors, which, respectively, are known as "Coconut Milk," "Emperador" and "Sailor Blue." In the QX50, the Sailor Blue-esque blue is applied to the center console, dash and doors in Ultrasuede. The Emperadorish brown is on the steering wheel, leather-wrapped dash top and doors, outer portions of the seats and the lower door portions. Coconut Milk is indicative of the creamy dash color and the seat leather, which is diamond-quilted and contrast-stitched. There's also open-pore wood trim. Though I made light of this, the QX50 Autograph interior is actually quite striking. As Infiniti points out, consumers are starting to embrace color, which is worth celebrating. Give me Coconut Milk, Emperador and Sailor Blue over beige, grey and black any day.

Infiniti boss ices plan for EV

Infiniti President Johan de Nysschen has postponed plans for an electric vehicle in order to focus on high-volume models. Automotive News reports de Nysschen is attempting to be realistic about Nissan CEO Carlos Ghosn's goal of nearly tripling Infiniti global sales from 170,000 units last year to 500,000 by March 31, 2017, saying, "500,000 cars by 2017 is an inordinately ambitious challenge." An electric vehicle would likely sell in rather small numbers.
Still, the executive is already making moves to improve Infiniti sales worldwide with new production in both China and England. Meanwhile, the company plans to unveil a new volume compact sedan set to bow in 2015. Meanwhile, de Nysschen is also working on two new models above the company's current M line. Those will borrow styling cues from machines like the Essence Concept, but will be far less exotic, tilting more toward high-performance luxury than true sports car.
