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 Q60 Concept paints a pretty picture of the brand's future

Infiniti's final teaser for the Q60 Concept may have given away the shape of the curvy coupe ahead of its debut at the 2015 Detroit Auto Show, but that's not necessarily such a tragedy for this model because the design has so many subtle touches. The more you look at it, the more cool details and ornate lines you notice. What initially looks fairly simple up front belies a multitude of fascinating details, including the F1-inspired lower air dam and the subtle fin at the tip of the hood. The design around the C-pillar may be complicated but is also attractive thanks to the confluence of design from the rear fender arch, beltline and crescent-shaped cutout in the window. The concept's interior also takes a minimalist approach. It's predominantly covered in cream leather and features sports seats in quilted leather. A mix of Alcantara and carbon fiber trim are able to show off the concept's performance intentions, though. Meanwhile the glass roof makes sitting behind the wheel feel airy and inviting. Underneath, the Q60 Concept's arching hood is the company's conceptual 3.0-liter, twin-turbocharged V6 and a seven-speed automatic. Infiniti promises the production of the mill is coming in the next two years. The big question is whether the mix of sharp edges and flowing lines on the Q60 Concept really see production without too much alternation. Infiniti plans to unveil the production version next year. Until then, check out how the model appears now on the floor of the Detroit show.

BMW reclaims US luxury sales crown from Mercedes

The numbers, they are in: BMW has reclaimed the luxury-sales crown from Mercedes by a margin of 9,347 cars. Mercedes donned the king's headgear in 2013 after a strong final quarter of 2013 when the new CLA and S-Class poured out of dealerships. This year, led by the 3 Series/4 Series and X5, BMW sold 339,738 units – a 9.8-percent increase year-on-year. Mercedes, led by the C-Class and M-Class, saw its sales go up by 5.7 percent to 330,391 units. We'll have to wait a bit to see if there's another registrations-vs-sales challenge as in 2012, when BMW was anointed US luxury ruler. Behind them, a dark horse named Lexus nudged closer to the leading Teutons, selling 311,389 cars. The Japanese luxury automaker also had the biggest gain among the top three, its sales rising by 13.7 percent compared to 2013. Audi had the biggest sales of anyone among the top five, though, with a 15.2-percent gain to 182,011, which moved it a spot ahead of Cadillac; the Wreath-and-Crest brand dropped 6.5 percent to 170,750. Acura (167,843), Infiniti (117,300), and Lincoln (94,474) took the final positions. Speaking of Lincoln, sales at the once-mighty luxury marque stand as the mightiest jump of any on this list, up 15.6 percent. That's the power of Matthew McConaughey... and better cars and a new crossover, sure. So now that we're back to Round One of 2015, in case no one else has said it yet: "Ok, fight!"
