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.

2023 Infiniti QX50 gets new Sport trim and more

The Infiniti QX50 is a perfectly fine SUV with attractive styling and great standard features. Perhaps its most significant fault is that its rivals exist, as the BMW X3, Audi Q5 and Cadillac XT5 all do the same things, just as well (better, in some cases), and for less money in higher trims. Even so, the QX50 is worth a look if you’re in the market, and the automaker just updated the SUV with a new trim level, better standard features and a new maintenance plan. Infiniti offers five QX50 trims for the 2023 model year: Pure, Luxe, Sport, Sensory and Autograph. The base Pure trim starts at $40,300, and pricing reaches $57,350 for the top trim. Buyers can opt for AWD in lower trims for a $2,000 upcharge, and the Autograph trim adds AWD as standard equipment. Infiniti Premium Care is standard for all QX50s sold in the United States, which includes oil changes, inspections and tire rotations for up to three years. The headline change for 2023 is the new Sport trim. It gets dark-painted 20-inch wheels, unique badging and gloss-black exterior trim. Inside, the Sport adds semi-aniline leather upholstery and a 12-speaker Bose audio system. Those upgrades build on the Luxe trim, which starts at $43,600 and brings most of the goodies the base Pure trim forgets. That means standard wireless charging, remote start and rear passenger alerts. All QX50s get a decent suite of advanced driver aids, including forward automatic emergency braking, pedestrian detection, rear automatic braking, blind spot monitoring, lane departure warnings and automatic high beams. The 2023 QX50 is too new to have received complete crash test results, but its predecessor scored “Good” in crash tests and “Superior” for front crash prevention systems.

Nissan Skyline Nismo gets a more powerful Z engine

Recent rumors claim the Nissan Skyline will morph into an electric crossover in the coming years. Regardless of whether or not they're true, the company isn't done with the current, gasoline-powered Skyline yet and it launched a limited-edition, Nismo-branded model in Japan. If you're experiencing deja vu, it's likely because the Nissan Skyline is sold as the Infiniti Q50 in the United States. We even get a range-topping, performance-oriented trim level, the 400-horsepower Red Sport 400. The Skyline Nismo goes further, though, by adopting an evolution of the twin-turbocharged, 3.0-liter V6 that powers the Red Sport 400 and the Z coupe. It's rated at 414 horsepower and 404 pound-feet of torque. For context, the Q50 and Z pack 400-horsepower and just 350 pound-feet of torque. The Nismo's engine spins just the rear wheels via a seven-speed automatic transmission, whereas America's Red Sport 400 is available with all-wheel drive. Nissan didn't settle for adding a few horses to the cavalry, slapping a couple of "Nismo" emblems to the body, and calling it a job well done. Its engineers redesigned the Skyline's suspension system, installed fade-resistant brake pads and recalibrated the various vehicle control systems, including the ABS, to deliver a sportier driving experience on and off the track. The brand even went as far as securing the windshield and the rear window with a type of adhesive normally reserved for the GT-R Nismo to improve rigidity without adding weight.  Visual updates are part of the Nismo package as well, including 19-inch Enkei wheels wrapped by tires that are wider than the ones worn by the regular-production model, an old-school "GT" emblem on each fender, and a body kit that includes a front splitter and side skirts. These updates aren't just for show: Nissan notes the redesigned grille opening helps channel additional cooling air to the radiator and the oil cooler. The Nismo treatment also permeates the cabin. The front passengers sit on Recaro sport seats with red inserts, while the driver faces a steering wheel with a red 12-o'clock mark as well as a new-look tachometer with a red ring and a small "Nismo" logo below the needle. Enthusiasts who want an even rarer version of the current-generation Skyline can try their luck at scoring the Nismo Limited.
