Infiniti QX80 refreshed for 2015, range-topping Limited trim added

Alongside the updated Q70, Infiniti has refreshed its fullsize SUV, the QX80, for the 2014 New York Auto Show. Like its freshened sedan, the QX80 is full of incremental styling tweaks typical of a mid-cycle update like this. Also like the Q70, there's a new member of the QX80 family for the 2015 model year.
But first, the overarching changes for the QX80 range. As we said, this is pretty standard fare, with new headlights and taillights and a restyled grille designed to fit the full-sizer in with the most recent Infiniti design language. Full LED headlights, turn signals and fog lights should provide a bit more illumination, while the mesh inserts on the "double-arch" grille remind us of the Q50. Still, this is a rather bulbous, inelegant piece of design in our eyes. Out back, the shape of the taillights has been tweaked, and they now sport LED illumination. The new rear bumper is larger, as well.
In the cabin, upgrades are similarly sparse. There are a few new tech items, like automatic high beams and predictive forward collision warning. Overall, though, this is the same wood-and-leather-lined cabin Infiniti has been selling for the past few years.

2015 Italian Grand Prix is smoke, mirrors, stalls, and stewards

For the first day-and-a-half of the Italian Formula One Grand Prix weekend, everything went to blueprint: Mercedes in front, Ferrari lurking, everyone else scrambling in their usual orders behind. Then qualifying came, and someone stirred the pot. About the only thing we expected was for Lewis Hamilton to put his Mercedes-AMG Petronas on pole position, the 11th time he's done it this year. He did it with a brand-new specification engine, one that represents not only an evolution in components, but also in power unit philosophy. Kimi Raikkonen lines up in second. It's been a long time since we read those words; the Iceman hasn't been on the first row since the 2013 Chinese Grand Prix, when he put his Lotus second on the grid behind... Lewis Hamilton. Raikkonen lined up just ahead of a Ferrari at that China race, then driven by Fernando Alonso. In Italy this weekend, he lined up in front of the Ferrari driven by his teammate, Sebastian Vettel, who qualified third. Both Ferraris benefitted from an upgraded power unit, ending a front-row drought for the scuderia that goes all the way back to Monaco in 2009 Germany in 2012. Nico Rosberg has a lot of work to do from fourth in the second Mercedes-AMG Petronas. Mercedes discovered a problem with Rosberg's engine but couldn't figure out the cause, so he reverted to the previous-spec engine he used in Belgium, one that's six races old. The lack of power hurt. Williams teammates Felipe Massa and Valtteri Bottas took fifth and sixth, with Massa seemingly given a team-ordered helping hand. Williams told Bottas to tow Massa down the front straight, giving Massa a blistering time in the first sector. Then Bottas did it again, ensuring he would line up behind Massa. The first Sahara Force India of Sergio Perez nabbed seventh, three places ahead of teammate Nico Hulkenberg in tenth, with Romain Grosjean in the Lotus behind Perez in eighth. Marcus Ericsson in the Sauber qualified ninth, but some clumsy driving saw him impede Hulkenberg twice. The stewards penalized Ericsson with a three-place grid penalty and two points on his superlicense, so Hulkenberg inherited ninth and Pastor Maldonado in the second Lotus inherited tenth. We hardly saw Hamilton during the race, because he led from the start, worked up a larger gap to second place on every lap, and didn't give up the lead for the whole event.

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:
