A look inside Infiniti's variable-compression engine

We're sympathetic to anyone who had trouble understanding what's going on with Infiniti's new variable-compression engine. While we got a full tech briefing on the novel VC-Turbo back in August, the visual aids were lacking. The cutaway engine Infiniti brought to the Paris show fixes all of that. You can thank the little green and pink lines on the cutaway for making the whole idea a little more clear. Click through the gallery to see two lines – one green and one pink – that represent the different strokes allowing for different compression ratios. Remember, the compression ratio is the amount of volume in the cylinder on intake compared to the amount at the end of the compression stroke. Leave more room at the end and you lower that ratio. The length of the stroke doesn't change with this system, but where it sits along the cylinder does. Hence those two lines. The variable compression ratio allows this new turbocharged engine to maximize fuel economy when the turbo isn't needed by raising the compression ratio. It will see its first use in the next Infiniti QX50 crossover, previewed by the QX Sport Inspiration concept that's also on display in Paris, and has performance targets of 268 horsepower and 288 pound-feet of torque. After, it will migrate to other Infiniti and Nissan vehicles, with transverse front-drive-based applications first in line. Eventually, it's likely to completely replace Nissan's corporate 3.5-liter V6. We'll be poking around the engine a little more in Paris today to try and get some more info. For now, enjoy those cutaway images and those friendly little lines.

Least satisfying vehicle rankings seek to highlight the worst cars of the year

Consumer Reports polls its members on all sorts of topics related to how they buy and use products ranging from mobile phones to humidifiers for indoor plants. Cars are regularly one of CR’s most interesting topics, and its recent study on the least satisfying vehicles to own offers insights into the cars people wish they hadnÂ’t purchased. CR polled thousands of members with questions about what they liked and disliked about the vehicle theyÂ’d owned for a few years. When asked if they would definitely repurchase the same car, the following vehicles came back as the least likely to be purchased a second time: Kia Forte: 51% would buy again Nissan Altima: 51% would buy again Nissan Kicks: 49% would buy again Volkswagen Taos: 48% would buy again Kia Seltos: 48% would buy again Jeep Compass: 46% would buy again Mercedes-Benz GLA: 45% would buy again Infiniti QX50: 40% would buy again Mercedes-Benz GLB: 39% would buy again Volkswagen Atlas Cross Sport: 38% would buy again When Autoblog tested the VW Atlas Cross Sport in March 2022, we liked the styling and the price was right, but it lagged rivals in driving excitement and interior quality. A number of recalls donÂ’t help the Cross SportÂ’s cause much, either, as some models have more than a dozen actions by the National Highway Traffic Safety Administration. Even the 2023 model already has four recalls. The annoyance of recalls and the hassle of just-average reliability ratings could have played into the Cross SportÂ’s place as the least satisfying vehicle. On the other end of the spectrum, the Chevrolet Corvette earned the top spot as CR's most satisfying car. The Porsche 911, Rivian R1T, Ford Maverick Hybrid, and Hyundai Ioniq 5 round out the top-five most satisfying vehicles to own. Given the rabid following the 911 has built over the years and the insane performance Chevy derived from the latest Corvette, itÂ’s not surprising to see them in the top spots.

Infiniti lays out four upcoming models, electric future to dealers

Infiniti recently held a meeting in Los Angeles for approximately 200 of its North American dealers. Much of the talk was geared toward calming skeptical franchise owners about the brand's staying power. To bolster that argument, Infiniti corporate gave the retailers a sneak preview of upcoming models intended to liven up a portfolio that's largely seen as stagnant. As Automotive News reported, dealers were treated to a first look at two gasoline models and two electric ones. All four were either crossovers or SUVs. Firstly, an all-new QX80 is expected to debut for model year 2024. Infiniti plans to move it upmarket with a price tag north of $100,000 to compete with Cadillac and Lincoln. We would expect a starting price below the six-figure threshold, with only top trim models going over the line.  AN describes the QX80's exterior design as blockier than its predecessor's, with a new corporate grille. Details include "piano key" head and taillights as seen on the QX55, as well as Tesla-esque door handles that are flush with the paint when not in use. Using the next-gen version of the popular Nissan Patrol as its base, the flagship SUV will replace its 5.6-liter V8 with a twin-turbo V6 that puts out about 450 horsepower. That's 50 more than the V8, but should return better mileage than the current 15 mpg combined. Luxury features reportedly include an air suspension that lowers when parked to make climbing in and out less strenuous, a 24-inch display spanning the dashboard, and plenty of legroom for second- and third-rowers. Expect a summer 2023 debut.  An all-new model called the QX65 will be positioned as a Lexus RX rival. Though based on the QX60, which is itself based on the Nissan Pathfinder. It loses the third row for a more coupe SUV-like profile. It's described as having the grille of the upcoming QX80 but "shark fin taillights".  Infiniti was one of the first companies to proclaim an electric lineup within a certain timeframe. That date was 2030, but the brand now lags behind BMW, Lexus and others. AN's report has a new Q70 sedan going on sale by the end of 2026 as Infiniti's first all-electric model. Attendees recounted a design that takes off from where the discontinued Q70 left off but with proportions that include short overhangs and a longer wheelbase. A new lighting signature illuminates the full width of the car. Comparisons were drawn to the Tesla Model S and Porsche.
