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.

Weekly Recap: An '80s encore in the auto world

The '80s returned in a big way this week, as National Lampoon's, Ghostbusters, Miami Vice, and even Tetris were back in the news. While there were far more serious topics (see below), nostalgia mingled with modern marketing to put these Reagan-era favorites back in the spotlight. The '80s were alternately cold and corny at times, but their cultural touchstones can still generate big money. That's why Infiniti recreated an iconic scene from National Lampoon's Vacation (1983) for an advertisement that hawks the QX60 crossover. Actor Ethan Embry, who played Rusty Griswold in a later Lampoon's movie, pilots the Infiniti – which is serving as a modern Family Truckster – for a trip to Walley World. A blonde pulls alongside in a red Lamborghini. They flirt, and she drives on. Christie Brinkley, who played the original girl in the red sports car (she drove a Ferrari in the '83 flick), is riding shotgun and chides Embry with: "A blonde. In a convertible. Seriously?" Okay, it's hardly on the level of "here's looking at you," or even "you can't handle the truth," but it should resonate with '80s babies, many of whom are now having children of their own and moving into three-row SUVs like the QX60. Naturally, Hollywood is going back to the well, too, with a Vacation remake that premiers July 29. Meanwhile, Ghostbusters is returning next year, and director Paul Feig offered a peak at the new Eco-1 in this tweet. In the 1984 classic, the team drove a modified 1959 Cadillac. Now, it will drive a late '80s Cadillac. As expected, the announcement generated support and controversy from movie and car enthusiasts. His tweet had generated several thousand retweets and favorites in the days following the news. Though the '80s Caddy looks, uh, less elegant in comparison to the now-iconic fins and curves of the original Ecto-1, it's about the same time lapse into the past as the '59 Caddy was to viewers in 1984. Speaking of 1984, Miami Vice, which debuted that year on NBC, is seeing one of its hero cars hit the auction block, Mecum Auctions announced this week. The 1986 Ferrari used on the show will be offered for sale Aug. 15 during Monterey classic car week. The white supercar runs a 390-hp flat 12-cylinder engine paired with a five-speed manual transmission and was in storage after the show ended in 1989 until earlier this year. It has 16,124 miles on the odometer and is authenticated by Ferrari North America and Classiche.

Infiniti Q30 Concept might be the cleverest Q model yet

When we first got official word of the Infiniti Q30 Concept, the Japanese automaker said that the crossover's "harmonious contrasts and dissymmetric philosophy" would "make an emotional connection with customers spontaneously." Now, we might not be heads of design studios or directors of marketing departments, but we're pretty sure we can translate that to: "The production Q30 will compete with the Audi A3 and Mercedes-Benz CLA-Class."
In all seriousness (if we can say that of a concept car painted a sort of rose metallic), the Q30 concept looks fetching here in Frankfurt; its rather convoluted and flowing bodywork just carried off successfully because of its grownup hatchback proportions and, frankly, huge wheels. The Q30 could seemingly slot into the current, attractive Infiniti range of production cars and not look amiss (though we'd prefer a color palette that looks a little less like Grandma's sitting room sofa).
