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 Prototype 10 concept to debut at Pebble Beach

Last year, Infiniti launched its gorgeous Prototype 9 concept at the Pebble Beach Concours d'Elegance. It was an open-wheel, retro-styled car inspired by Grand Prix racers of old. Just as important as its design, though, was its powertrain. It was all-electric. This year, at Pebble Beach, Infiniti will return with a new speedster concept called Prototype 10. It, too, will be electrified. Teased in the above image, the open-cockpit Prototype 10 will be another single-seater steeped in classic design, though with looks the automaker describes as "cool, clean and forward-looking," borrowing some cues from the Infiniti Q Inspiration concept we saw at the Detroit Auto Show earlier this year. Karim Habib, Infiniti's executive design director, describes Prototype 10: The Infiniti Prototype 10 echoes the layout and design of some of the most evocative car designs of all time, where power was celebrated through high-powered single-seat competition cars. Our new concept speaks of an electrified future, something which is reflected in its form and details. It is appropriate that we found inspiration in an optimistic bygone era in which cars were characterized by the simple love of driving. Still, Infiniti leaves out most of the details about the car. We're curious what kind of "electrified" powertrain Prototype 10 will use, but the company plans to electrify its whole lineup beginning in 2021. It's possible Infiniti could tease further images and information, but we'll likely have to wait for its official unveiling at Pebble Beach on Aug. 23, which is right around the corner. If the last two concepts are any indication, this one should be a stunner as well. Related Video: This content is hosted by a third party. To view it, please update your privacy preferences.

Race Recap: Abu Dhabi GP is reversals, luck, leanness and last dances

We weren't sure if Alter Ego Nico Rosberg, the one who flew into Brazil and showed Mercedes AMG Petronas teammate Lewis Hamilton that he knew also knew how to grab an entire race weekend by the scruff of the neck, arrived in Abu Dhabi. In both Friday practice sessions Hamilton showed Rosberg the way. Then on Saturday, Alter Ego Rosberg took over, taking the last Free Practice session and then pole position by a whopping four-tenths of a second over Hamilton. Thanks to the gimmicky and soon-to-be-obliterated spectre of double points, if Rosberg won the race and Hamilton finished lower than second, the World Championship would remain in German hands. Behind Hamilton came the Williams duo, again, with Valtteri Bottas ahead of Felipe Massa. Daniil Kvyat did swell to put his Toro Rosso in fifth, Jenson Button was just as swell getting his McLaren into sixth. Kimi Raikkonen outqualified his Ferrari teammate Fernando Alonso for the third time this year, the pair taking seventh and eighth on the grid. Kevin Magnussen lined the second McLaren up in ninth, Jean-Eric Vergne making the top ten for Toro Rosso in his last race for the team. To be clear, that was the final grid for race: Daniel Ricciardo and Sebastian Vettel had both qualified in the top ten but were sent to the back of the grid when their Infiniti Red Bull Racing front wings were deemed illegal. They'd start from the pit lane, which was still ahead of Romain Grosjean in the Lotus, who took so many penalties for new engine components that he started the race in Turkey. At lights-out on Sunday, well, it was pretty much lights out. That's when Hamilton got the start of the year, bolting off the line so quickly it didn't take him 100 meters to get in front of Rosberg. The Brit took Turn 1 in the lead, then laid more than a second into the German on the first lap. Rosberg kept close, about 2.5 seconds back, but it was Hamilton's race to lose and everyone knew it; barring a reliability issue or the kind of driving mistake Hamilton hasn't made all year, Britain would have its fourth double world champion. Rosberg was left asking his engineer what kind of strategy they might use to claim first place. That reliability issue did come, but it struck Rosberg on Lap 26 when his entire Energy Recovery System failed, robbing him of 160 horsepower and taxing his brakes.
