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.

2023 Infiniti QX60 Review: Now worth checking out

Pros: Well-equipped; handsome interior; sharp exterior styling; solid towing capacity Cons: No hybrid option; cramped third row; there are better three-rows for the price The 2023 Infiniti QX60 is relevant and worth considering for the first time in a long while. It’s based on the proficient Nissan Pathfinder, and Infiniti brings a lot of good to the table with this three-row SUV. The design is immediately eye-catching, as the curvaceous body panels blend and wrap around this rear, giving it a very sleek and attractive profile. Plus, its beauty isnÂ’t just skin deep. Infiniti ditched the old modelÂ’s frustrating CVT for a nine-speed automatic transmission, and the result is a driving experience that better matches its luxury car badge. It would be nice if there was more than just the standard 3.5-liter V6 available — such as a hybrid or PHEV — but the single engine is at least a competent one with enough power for above-average towing capacity. Despite the QX60 being a perfectly competitive SUV these days, donÂ’t think that itÂ’s now a class leader. Other options in the luxury space such as the Acura MDX, Lincoln Aviator and Volvo XC90 would find their way into our garages before the QX60. Even non-luxury-branded alternatives such as the Jeep Grand Cherokee L or Hyundai Palisade/Kia Telluride in their top trims compete strongly against the QX60. The base models offer a plethora of standard equipment that many luxury manufacturers donÂ’t offer, so the best play Infiniti has to offer is in value. That said, if you want every luxury in the book, the top-trim Autograph delivers with gorgeous interior appointments and a high-tech cabin. ItÂ’s still tough to recommend the QX60 over others in this segment, though, as the over-$50,000 starting price puts it squarely in the sights of our favorite three-row vehicles.

The QX60 was all-new last year, but Infiniti has a few updates for 2023. The wireless charging pad is now standard across all trims. A frameless rearview mirror is added, and the lower bumper accents are updated with new colors. Lastly, all QX60s will now have "Infiniti Premium Care" as standard, which includes three years of free inspections, oil changes and tire rotations.

Race recap: 2015 Singapore Grand Prix full of odd sideshows

What greeted the Formula One teams in Singapore? Confusion. The haze was so thick that observers wondered if the race would be held at all. Then practices began, and Mercedes-AMG Petronas driver Nico Rosberg took the first one, but the team fell away after that. Mercedes said it couldn't get the tires turned on, but no one believed the Silver Arrows was in genuine trouble. Then qualifying set the confusion in stone. Ferrari driver Sebastian Vettel laid down the best time in Q3, taking the team's first pole position since Germany in 2012. Daniel Ricciardo got his Infiniti Red Bull Racing into second, about one tenth behind Vettel. (That may make the team feel better after Ricciardo publicly asked for a better engine than the current Renault unit, and team advisor Helmut Marko said the outfit will quit F1 at the end of this year if it can't get a stronger powerplant for 2016.) Kimi Raikkonen put the second Ferrari in third, Daniil Kvyat put the second Red Bull in fourth. And only then came the Meredes'. Lewis Hamilton's best got him fifth, the Brit saying, "We don't really know what we have got wrong. For some reason the tires are not working on the car. We do the warm-up the same as everyone else and then you see someone one second up the road." For added emphasis on the reversal of fortune, his time was 1.6 seconds behind Vettel's. Teammate Rosberg is next to him in sixth, a further half a second back. Williams is still a hurting a bit on slow tracks, so Valtteri Bottas could only get into seventh ahead of Max Verstappen in the Toro Rosso and teammate Felipe Massa in ninth. When the red lights went out, the 2015 Singapore Grand Prix would get both less interesting and more interesting all the way to the final lap. The men up front got good getaways, and the order into Turn 1 was Vettel, Ricciardo, and Raikkonen. The race finished with those three in that order, never having conceded position. Vettel's Ferrari enjoyed the track so much that he laid a second per lap into Ricciardo for the first five, then relaxed. He'd let the gap come down later in the race a couple of times, but any time he wanted to see what his mirrors looked like without anyone in them he'd take off again. Rosberg took fourth position after holding down sixth for the first stint. It looked like he'd have an even worse day - for a Mercedes driver - when he had problems getting his car started and onto the grid before the race.
