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 introduces Q70 Premium Select Edition to Monterey crowds

Infiniti has made its presence at the 2015 Monterey Car Week known, introducing a new version of its flagship sedan, the Q70. As far as special editions go, the new Premium Select Edition Q70 is fairly light on upgrades, going for minor aesthetic tweaks rather than rocking the boat too heavily. Unsurprisingly, one of the most obvious changes is down low, where Infiniti's stylists have fitted new 20-inch wheels. The gunmetal hoops are joined by dark chrome trim on the fascia, a new rear bumper, and a decklid spoiler. Buyers have the choice of two interior trims. There's Graphite and Stone, both of which feature semi-aniline leather, a "suede-like" headliner, and aluminum interior trim pieces. Infiniti isn't too picky when it comes to powertrains for the Premium Select Edition, although there are some restrictions. It can be had with both the 3.7-liter V6 and 5.6-liter V8 and in rear- or all-wheel-drive models. Weirdly, though, you can't get the stylish trim on the Q70 Hybrid or on long-wheelbase models. We can't tell you how much it'll cost to add the special-edition trim, because Infiniti did not deign to release pricing info. We can, however, tell you that the Q70 Premium Select Edition will hit dealers this November. Look for more, including live images of the new sedan, as the Monterey Car Week continues. Until then, scroll down for the official press release.

The specially equipped Q70 premium sedan will be available at Infiniti retailers nationwide beginning in November. "Following the introduction last year of the new Infiniti Q70 long-wheelbase model, we are continuing to expand our flagship Q70 sedan's portfolio of offerings," said Randy Parker, vice president, Infiniti Americas. "The new Premium Select Edition package gives the Q70 an extra touch of premium elegance that is right at home here at Pebble Beach – or in any neighborhood or driveway across the country." The Q70 Premium Select Edition's exterior offers dark chrome trim, a darkened lower rear bumper, a rear decklid spoiler and unique design and color 20-inch aluminum-alloy wheels with 245/40R20 all-season performance tires.

These cars are headed to the Great Crusher In The Sky

It happens every year. We bid adieu to some cars and trucks that will be missed, and say good riddance to others wondering how they stayed around so long. Whether they're being killed off for slow sales or due to a new product coming along to replace them, the list of vehicles being discontinued after 2012 is surprisingly long and diverse.
CNN Money has compiled a list of departing vehicles, to which we've added a few more of our own. In the slow sales column, cars like the Lexus HS 250h, Mercedes-Benz R-Class and the full Maybach lineup appear, while the Ford Escape Hybrid, Mazda CX-7 and Hyundai Veracruz are all having their gaps filled with more modern and more fuel-efficient alternatives. Obvious exceptions to the rule include models that still sell in decent numbers like the Jeep Liberty and the Chrysler Town & Country (which will eventually be replaced by a crossover-like vehicle).
