Infiniti's variable compression engine in the 2019 QX50 is the first of its kind

The world's first variable compression ratio engine is here, in a production car. That car is the 2019 Infiniti QX50, debuting this week at the Los Angeles Auto Show. The midsize crossover has seen a refresh that has brought it an all-new platform together with new driver assist features, but it's the engine that's the centerpiece here. Nearly everything is continuously variable under the hood of the QX50 – not only the new shift-by-wire XTRONIC CVT. The new VC-Turbo gasoline engine is able to change its compression ratio from 8:1 to 14:1, or anything in between depending of the driving situation; whether there is need for top-end power or turbodiesel-like torque from low revs, or optimized fuel economy. The pistons' reach is continuously adjusted by an electric "Harmonic Drive" motor, which controls a multi-link system, affecting the top-dead-center of the pistons and changing the compression. The engine can also switch between efficiency-maximizing Atkinson cycle and regular combustion cycle, on the go – and there's both multipoint injection and gasoline direct injection employed. The result is 268 horsepower at 5,600 rpm and 280 pound-feet of torque at 4,400 rpm; good figures for a 2.0-liter four-cylinder gasoline engine with a single-scroll turbocharger. Infiniti says that the FWD version's fuel economy of 27 miles per gallon combined is 35-percent better than the previous-generation V6 engine; in AWD guise, it reaches 26 mpg, which is a 30-percent improvement. The new engine is pretty much all-aluminum, but the vaguely magical-sounding "transformative multi-link components" behind the variable compression system are made from high-carbon steel alloy. The engine's multi-link system also enables it to do away with any balancing shafts, and Infiniti compares its smoothness to a V6 rather than a regular four-cylinder. In addition to the aforementioned tech, the VC-Turbo engine has the world's first active engine mount vibration damping system to smoothen its operation even further. Related Video:

Infiniti QX Monograph Concept debuts at Pebble Beach looking large

The Infiniti QX Monograph Concept is here, and it sure presents like a veiled look at the next Infiniti QX80 SUV to us. Now, Infiniti didn’t make any allusions to the QX80 in its announcement at Pebble Beach, but the full-size dimensions and general shape tell us pretty much everything we need to know. This reveal is also a continuation of InfinitiÂ’s “Monograph” line of concept cars with the most recent one being the QX60 Monograph. That concept previewed what would become the production QX60, suggesting that this next Monograph concept will do the same for the larger QX80. As for the details of this particular design concept, Infiniti went into great detail about all its elements. Starting up front, the grille is meant to evoke a bamboo forest with its gentle arcing lines surrounding the new Infiniti logo. Meanwhile, the black finish and surround hint at the power found behind it — Infiniti didnÂ’t say what this concept is powered by, but we fully expect the next QX80 to have a gasoline engine situated under the hood. Flanking the grille are the lights that Infiniti says feature its “digital piano key” design and both “welcome” and “farewell” animation sequences. Since the headlights and DRLs are separated, Infiniti went ahead with that intricate “piano key” look for the DRLs to create a distinct signature. They wrap from the grille to around the side of the front bumper in an attempt to emphasize the width and height of the QX Monograph. You really get a sense of the QX MonographÂ’s size from its side profile. It has a vast monotone greenhouse that visually separates itself from the body by being painted entirely in black. The minimalist styling Infiniti says it used for this vehicle is best seen from this angle. It has electric door handles that pop in and out to create an uninterrupted look all the way down the side of the SUV. Meanwhile, the massive wheels bring some visual pizazz to the whole package. TheyÂ’re machine-finished wheels with both black and red accents arcing through, and Infiniti says its design inspiration for them was wind turbines. And on the topic of paint, Infiniti says it developed a new hue called Akane for this concept. ItÂ’s difficult to tell in photos, but the six-layer paint glows in the sun in an attempt to mimic “a warm glowing red sunset as it transitions into a dark night sky.” Of course, in most conditions, itÂ’ll likely just look gray.

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.
