Infiniti Q Inspiration Concept shows a future with variable compression

For weeks, Infiniti has been teasing the Q Inspiration Concept ahead of its official debut at the Detroit Auto Show. Details were absent, but the design was clean, swoopy athletic. Not seeing any tailpipes on the rear end, we hoped it could sport some kind of electrified powertrain, but surmised that Infiniti could take the opportunity to further showcase its variable compression turbocharged engine technology. Now, Inifniti has officially taken the wraps off its Q Inspiration Concept, and has indeed chosen to use the stunning show car to demonstrate "near future applications" of the potent yet efficient VC-Turbo tech. VC-Turbo made its production debut in the 2019 QX50 at the 2017 Los Angeles Auto Show. Here, in the Q Inspiration, VC-Turbo allows Infiniti designers to make the most of the packaging, taking advantage of the compact powertrain to increase the size of the cabin while maintaining the footprint of a mid-size car. Electric automakers like Fisker, Lucid Motors and the like have been doing something similar with electric powertrains, but Infiniti's VC-Turbo allows the company to do something similar with technology that is ready for primetime, while still bridging the gap to more efficient future powertrains. VC-Turbo, as we've learned earlier, allows the engine to change and optimize compression ratios on the fly, between 8:1 for high-performance situations, to 14:1 for maximum efficiency. Mounted to the exhaust manifold integrated in the cylinder heads of the four-cylinder engine is a single-scroll turbocharger. The system, says Infiniti, provides the torque and response of a hybrid or turbodiesel powertrain without sacrificing efficiency. In the Q Inspiration, the power is directed to four wheels via a front-biased all-wheel-drive drivetrain. The system can direct torque to the rear wheels individually as needed. As a design study, the Q Inspiration is a success. The proportions and lines are sleek and attractive, accentuated by the car's white paint. There's kind of a lot going on up front, with a large "double-arch" grille at the leading edge. Everything behind that, though, looks particularly harmonious. Its elongated cabin and coupe-like dimensions help provide efficiency while maximizing headroom for the four occupants. It's a car that stands up to close inspection, as attention to detail makes it more interesting the closer you scrutinize it, inside and out.

Watch the 2022 Infiniti QX55 reveal livestream at 8:55 p.m. EST right here

The car reveals are coming in quick succession today, and last up is the 2022 Infiniti QX55. Infiniti will be hosting a stream at 8:55 p.m. ET tonight to reveal the crossover coupe version of its popular QX50. Artist Aloe Blacc will be hosting the event and hyping the car up from the Belasco Theater in Los Angeles. Additionally, Infiniti will have designers and executives on hand to speak about the car and its development and background. If this reveal is anything like the Nissan Z Proto reveal, expect a number of folks on hand and a detailed look at the crossover. You can watch it all in the video stream at the top of this post via YouTube. We already know what to expect coming into this reveal, thanks to a recent teaser from Infiniti and spy shots (see the gallery below) captured at the beginning of the year. It’s going to look like a chopped and coupe-ified QX50. The VC-Turbo engine should be under the front hood, and “shifting” will likely be handled via a CVT. Check back with this post just before 9:00 p.m. ET to see the video reveal, then head on over to our full reveal post on our home page where you can get a more detailed breakdown of whatÂ’s new and different in the QX55.

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.
