10 of 18 midsize SUVs earn 'good' IIHS side impact safety rating

It's not terribly surprising that midsize SUVs earned better safety ratings than small SUVs in the latest side-impact tests performed by the Insurance Institute for Highway Safety (IIHS). Just how much better they scored, on the other hand, certainly raises an eyebrow. Ten out of 18 midsize SUVs earned the highest rating of 'good' in the stringent new test, altered for vehicles starting with the 2020 model year with a heavier barrier (4,200 pounds) that moves at a higher speed (37 miles per hour) and is fitted with a hard honeycomb frontal structure. By way of contrast, just one out of of 20 small SUVs earned a 'good' score.  SUVs that receiving 'good' scores were the Ford Explorer, Infiniti QX60, Lincoln Aviator, Mazda CX-9, Nissan Pathfinder, Subaru Ascent, Toyota Highlander, Volkswagen Atlas, Volkswagen Atlas Cross Sport and Volkswagen ID.4. For EV fans, it's worth noting the ID.4 was the only electric vehicle included in the test. The Buick Enclave and Chevrolet Traverse scraped away with 'acceptable' ratings while the Honda Passport, Honda Pilot, Hyundai Palisade, Jeep Wrangler 4-door, Kia Telluride and Nissan Murano were deemed merely 'marginal' in the tough new test. Only two models — the Mazda CX-9 and Volkswagen ID.4 — earned a "Good" rating in every test category.  Interestingly, the Jeep Wrangler would have scored a 'good' rating if it were equipped with side airbags for the rear seating positions. It would likely be an engineering challenge to equip its removable top and/or doors with airbags, but the lack of that safety feature allowed the head of the rear passenger dummy to hit the vertical support of the top. Otherwise, the Wrangler scored good ratings across the board. The new Ford Bronco, which makes more allowances for side-impact safety, has not yet been tested.  The popular Hyundai Palisade and Kia Telluride SUVs stand out in the test with 'poor' ratings for driver pelvis injuries. The Nissan Murano, a vehicle last redesigned for the 2015 model year, was the only vehicle tested that received a 'poor' rating for its structure and safety cage. Videos of the tests of 12 of these 18 SUVs can be found on the IIHS' YouTube page.

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.

2021 Infiniti Q50 Red Sport 400 Road Test | Z engine preview

There isn’t much reason to take another look at the 2021 Infiniti Q50 Red Sport 400 on the surface. ItÂ’s largely the same sedan as it was when we drove it in 2016: powerful and stylish, but lacking in tech and polish. However, whatÂ’s under the hood is of far more interest to us today than it was just a year ago. ThatÂ’s because the 3.0-liter twin-turbo V6 powering this Infiniti is migrating over to the next Nissan Z car. Nissan announced that the production Z would get a 3.0-liter twin-turbo V6 not long after it revealed the Z Proto. There are no other twin-turbo V6s in NissanÂ’s arsenal but this one, meaning that the VR30DDTT engine in this Infiniti is destined for the Z — plus, there's photo confirmation. The big question remaining is: How new or different will it be? Its most potent state of tune is rated at 400 horsepower and 350 pound-feet of torque. ThatÂ’s a high number versus most other boosted six-cylinders, and perhaps most importantly, itÂ’s more potent than the 382-horsepower 2021 Toyota GR Supra 3.0. As weÂ’ll soon explain, though, numbers only tell part of the story. Transplanting the InfinitiÂ’s V6 into the next Z surely wonÂ’t be without challenges, either. Nissan is promising a six-speed manual in the Z. Meanwhile, this engine is exclusively paired with a traditional seven-speed automatic transmission in the Q50 and Q60. Nissan hitched this engine up with a manual in a 370Z SEMA show car years ago, but now it must devise a production car solution. ThereÂ’s also the question of whether Nissan will use the same seven-speed as the automatic option in the Z, or come up with something a bit more aggressive. The cost-efficient (and likely) solution would be reusing the seven-speed, not unlike the Supra's eight-speed traditional automatic.  Having all of this in mind, we set out to see how this engine sits today as a preview to the Z.  Going from the big, naturally aspirated VQ series V6 to a smaller twin-turbo V6 will bring about the obvious changes. The rabid and uncouth personality of the outgoing VQ is nowhere to be found in the sweet and smooth new engine. ItÂ’s not quite the silky, effortless BMW inline-six found in the Supra, but it brings an air of refinement and maturity that's simply not there in the current Z. And then thereÂ’s the torque. All 350 pounds of twist are available at 1,600 rpm in the Q50 Red Sport 400, which means the shove in the back would theoretically start just off idle.
