2025 Infiniti QX80 First Look: Can it command a hundred grand?

NEW YORK CITY — If Infiniti has its way, the all-new 2025 QX80 will be the flagship SUV that leads NissanÂ’s luxury marque into a much-needed renaissance. By the time the 2025 QX80 debuts, the current generation will have been on the market for 15 years. The model dates to 2010, when it debuted as the QX56 (prior to InfinitiÂ’s naming system revamp). The QX56/QX80 received a lot of hate for avant-garde styling that appeared to have been birthed from an H.R. Giger space horror. The 2025 iteration tones that down significantly with fewer curves and more chiseled lines. As previewed by the QX Monograph concept, the complete absence of surfacing on the sides is as unfussy it gets. The nose retains InfinitiÂ’s trademark double-arch grille, inspired by the enduring stone bridges of traditional Japanese gardens. Similarly, its vertical slats are meant to evoke the spires of a bamboo forest. The new Infiniti logo is now 3-dimensional, with the “infinite road” dropping into the center like a black hole. Unlike a black hole, it illuminates in an eye-catching effect that, thankfully, feels less pretentious than MercedesÂ’ glowing stars. At the rear, a full-width taillight bar recalls lights reflected in water and is made up of more than 300 LEDs. The thin lights flanking the grille are DRLs, while the QX80Â’s real headlights are embedded in nooks just above vents on either side of the front fascia. Happily, those vents are functional, directing cooling air to beefy two-pot calipers and 13-inch discs. Likewise, the (finally de-chromed!) driverÂ’s side fender vent acts as a heat extractor. That heat is generated by a new twin-turbo 3.5-liter V6 that replaces the outgoing naturally aspirated V8. Mated to a 9-speed automatic, it hails from the same engine family as the GT-R supercar and makes 450 horsepower and 516 lb-ft of torque, a surge of 50 horses and 105 lb-ft. At the same time, Infiniti says it gets 20% better fuel economy. Many forget that beneath the predecessorÂ’s alien beluga sheetmetal was a solid luxury SUV with real off-road bones. It was built on the same platform as the Nissan Patrol, a hard-core 4x4 that competes toe-to-toe with the legendary Toyota Land Cruiser in foreign markets. Come 2025 the QX80 will continue to share a chassis with the new Patrol, albeit an all-new body-on-frame unit that Infiniti says has 57% more lateral stiffness than the outgoing model and 300% increased torsional stiffness.

Infiniti's new VC-T changes the rules of small turbocharged engines

The upcoming Infiniti QX50 crossover does not get our pulse racing, no matter how shapely the QX Sport Inspiration concept that previews it may be. No midsize SUV does, to be fair. But it has something special under the hood – the world's first production variable-compression-ratio engine. That means the QX50's 2.0-liter turbo four, which makes 268 horsepower and 288 pound-feet of torque, will have up to 27 percent better fuel economy. Here's how it works. The trend of moving to smaller, turbocharged engines carries with it one big falsehood. Under low load when the turbo isn't needed, these engines are less efficient than an equivalent engine without a turbo because of the low compression ratio the turbo requires. That is, if you never need the extra power, you're wasting fuel. Turbocharged (and supercharged) engines use a lower compression ratio to prevent detonation. When you force extra air in a cylinder and mix it with fuel, it's more likely to prematurely go boom. Lowering the compression ratio prevents this problem, but it's less efficient. Infiniti's VC-T promises the best of both worlds, with a compression ratio that ranges from 8.0:1 for high-power turbo needs to a 14.0:1 ratio for fuel-sipping efficiency. At its heart the VC-T engine is a simple idea, but it's complicated to explain. Consider yourself warned. The photo below from Infiniti serves as a good visual overview. For the truly nerdy, this patent application covers the mechanical concept. Instead of having the pistons connected to the crankshaft, Infiniti's engine has a pivot arm with a connection on each end. One end connects to the piston, the other connects to a second lower shaft, which is controlled by an actuator arm. At any given time the engine's pistons move up and down according to the lobes on the crankshaft. But the actuator arm can change the angle of the pivot arm up and down. That is, the pistons still move in the same motion with the same stroke, but phase the entire stroke up or down. Move the pivot up and there's less room at the top, which means a higher compression ratio. Move the pivot down and the compression ratio goes down, too. As an added bonus, the lower shaft eliminates the need for counter-rotating balance shafts. Infiniti says this system works constantly and can vary the compression ratio to any number between 8:1 and 14:1. It also uses electronic variable valve timing on the intake valves to switch into Atkinson-cycle combustion for greater efficiency.

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.
