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:

2016 Infiniti QX50 First Drive [w/video]

One crucial change to the 2016 Infiniti QX50 (formerly known as the EX35) may have just made the company's smallest crossover suddenly relevant. So how does one add appeal to an eight-year-old model, without any significant cosmetic or powertrain updates? By addressing its biggest flaw head-on: size. For the 2016 model year, Infiniti has stretched the QX50's wheelbase by 3.2 inches, and the crossover is now 4.5 inches longer overall. In addition to a roomier cabin – 8.3 cubic feet more to be exact – there's one number that sticks out above all else: four more inches of knee- and leg-room in the back seats. Like scoring an exit-row seat on your flight, the extra space may be just enough to change the experience. So how can the upmarket Japanese automaker justify costly changes to the platform when it's only moving 250 of these vehicles in the US per month? Americans can thank the Chinese for that. As in the US, sales of small crossovers are quickly rising in China – a country where being chauffeured is more common for those of means – and rear-seat passengers who can pay for a driver don't want to feel like they're sitting in the penalty box. The platform-sharing economics work, and in this case, everyone stands to benefit. Pricing is reduced by $500 from last year, with the rear-wheel-drive 2016 QX50 now starting at $35,445 after delivery. Infiniti says it considers the Acura RDX and Lexus NX as the QX50's direct competition, but it's worth noting that both of those competing models sell more in just one month than Infiniti's smallest crossover sold all of last year. The QX50 isn't likely to reach its competitor's levels anytime soon, but Infiniti hopes the roomier iteration will pique shopper interest. To help that cause, the 2016 model gets a few light cosmetic touches too. Up front it receives a new grille that's more in line with the brand's current design language, new LED fog and daytime running lights, new door mirrors with LED turn signals, revised side sills, and a new rear bumper. Beyond aesthetics, pricing is reduced by $500 from last year, with the rear-wheel-drive 2016 QX50 now starting at $35,445 after delivery. The all-wheel-drive version adds another $1,400 to that price. All models get more standard equipment, including a power moonroof, heated front seats, and the new LED accents. Inside the cabin, things look much as they did when the crossover first debuted as the EX35, back in 2007.

2025 Infiniti QX80 confirmed with 450-hp twin-turbo V6, 50 hp more than now

Infiniti's back to tease the 2025 QX80 that debuts in 15 days. Automaker executive Ivan Espinoza starts by telling us what we already knew, the ancient 5.6-liter V8 gets sent packing by a 3.5-liter V6. Espinoza calls it "all-new," but this is in reference to the application. Parent company Nissan loves itself a TTV6, the GT-R given the codename VR38DETT, the new Nissan Z's version codenamed VR30DDTT, the same mill formerly serving the Infiniti Q50 and Q60. The 3.5-liter displacement in the QX80 means its engine can be expected to be called the VR35DDTT. We've got output numbers at last, those being 450 horsepower and 515 pound-feet of torque, improvements of 50 hp and guaranteed-to-feel-it 102 lb-ft. That outdoes the closest Japanese competition, the Lexus LX that gets 409 hp and 479 lb-ft from its TTV6. The 2025 QX80 is going to shift through a nine-speed automatic gearbox, the two additional cogs over today's seven-speed providing a 40% wider range of ratios. Owners are going to get more performance down low and efficiency up high. Doubling up on the efficiency, engineers added active grille shutters to reduce drag when massive cooling isn't needed. Espinoza also cites "a new chassis and larger frame," however, the QX80 is expected to ride on an updated version of the current SUV's body-on-frame platform, Nissan's F-Alpha that once served the Pathfinder and Titan, plus the erstwhile QX56, and still serves the Nissan Frontier. The evolution yields 57% more lateral stiffness and 25% more torsional rigidity. A new electronic air suspension with active damping keeps the hardened cage from becoming a punishment. We get our best, albeit very brief, looks at the interior as well. The four-spoke wheel is now a two-spoke wheel, a la Genesis. The digital gauge cluster and separate infotainment binnacle morphed into what looks like a single, uncovered widescreen (composed of two or more screens), akin to what we've seen in several electric vehicles like the Kia EV9 and Honda e. The restraint and subtlety in these snippets matches what's been done to the exterior, so far as we can see. The livestreamed reveal happens March 20, expect a Monograph Concept plus some flourishes. A week later, we'll get up close and personal for the 2025 QX80's public debut at the New York Auto Show.
