Infiniti QX50 concept previews production model with variable compression engine

Infiniti revealed its QX50 concept ahead of its official debut at the Detroit Auto Show, and despite the concept title, it looks pretty much production-ready. The company calls the crossover "an evolution of the QX Sport Inspiration" concept, and that's certainly accurate. Side-by-side, the QX Sport, which we already figured was previewing a new QX50, and this concept look nearly identical. The primary changes are bumpers and side skirts that feature the obligatory aluminum trim to look like skid plates, and simple black plastic fender flares. The overall result is a crossover that is pleasant but not exactly exciting that bridges the gap between the small and swoopy QX30 and the large QX60. The plain wrapper hides plenty of impressive technology, though. Under the hood is Infiniti's fascinating variable-compression turbocharged engine. It's a 2.0-liter inline-four that can alter its compression ratio to anything between 8:1 and 14:1. The result is an engine that produces an estimated 268 horsepower and 288 lb-ft of torque. Infiniti says the four-cylinder should be about 27-percent more efficient than a comparable V6. In addition, while the company says this concept just shows a potential application of the engine, it's safe to say that you can expect it in the production model. With the new engine, the QX50 will also switch from to a front-drive platform, with all-wheel drive definitely an option or possibly standard; the current QX50 is based on the aging rear-drive FM platform used on other Infinitis and the Nissan 370Z. The other new tech buried in the QX50 concept's body is what Infiniti calls the "first production-ready incarnation" of its ProPilot semi-autonomous technology. The company doesn't go into great detail about what it will do except for handling stop-and-go highway traffic. We would hazard a guess that the system is functionally the same as the one introduced on the Nissan Serena minivan in Japan. It goes by the same name and can handle stop-and-go traffic, as well as maintain the car's lane position and distance behind other cars. It's another safe bet that we'll see this system in the production model. Other details about the car, such as the interior, have yet to be revealed. We're sure to see it as well as other information about the QX50's technology when it makes its full debut in Detroit. Related Video:

Porsche tops J.D. Power quality index as Korean brands soar

While complaints about infotainment systems remain a thorn in the side of automakers for J.D. Power's annual Initial Quality Study, there's a lot to celebrate this year. The average number of problems reported per 100 vehicles fell to 112 in 2015 – a three-percent improvement compared to 116 in 2014. The results of this year's survey are based on the responses of over 84,000 people about problems within the first 90 days of buying or leasing a 2015 model-year vehicle. For the third consecutive year, Porsche tops the rankings with an average of 80 problems per 100 vehicles. Although, that's slightly more than the 74 the German sportscar maker scored in 2014. "While the Japanese automakers continue to make improvements, we're seeing other brands, most notably Korean makes, really accelerating the rate of improvement," Renee Stephens, vice president of US automotive quality at J.D. Power, said in the study's release. In fact, Kia ranks as one of the biggest movers in this year's list. The Korean brand jumped to second place from seventh last year. The company had an average of 86 problems per 100 vehicles, a 20-point improvement. Third place went to Jaguar with an average of 93 problems reported, versus last year's second-place finish with 87 of them. Fourth place was Hyundai, and fifth-place Infiniti also earned a gold star for improvement with 97 issues per 100 vehicles – 31-points better than last year. Fiat still anchored the bottom of the list. However, its 161 problems this year is a lot better than the 206 in 2014. Ranked by nationality, Korean brands (Hyundai and Kia) are now leading the industry in initial quality with an average of 90 problems reported per 100 vehicles. According to J.D. Power, this is the first time Europe's figure beat Japan with 113 and 114 issues, respectively. The American brands also averaged 114. Whereas General Motors dominated last year, the segment awards are spread out in 2015. GM, Hyundai, Nissan, and Volkswagen Group are all tied with four models each earning prizes.

2025 Infiniti QX60 ditches V6, gains VC-turbo

The 2025 Infiniti QX60 will ditch its long-running VQ-series V6 in favor of Infiniti's variable-compression turbo engine. There's news beyond the powertrain overhaul too as the 2025 model sees some equipment upgrades and a new Black Edition. The blackout package is not new to Infiniti, but it's a first for this QX60. Let's start under the hood.  With 268 horsepower and 286 pound-feet of torque, the VC-T four-cylinder gives up 22 horses in exchange for 16 lb-ft of torque. That's a bit of a side-grade rather than an upgrade, perhaps, but the new four-cylinder delivers better fuel economy, making the whole pill a bit easier to swallow. The FWD model will return 22 mpg city, 28 mpg highway and 24 mpg combined, the EPA says (vs. 21/26/23 with the V6) while the AWD model improves to 22 mpg city, 27 mpg highway and 24 mpg combined (from 20/25/22). That's a 10% bump in city mileage vs. the V6 — not earth-shattering, but not bad, either. And we know what you're thinking, but fear not; this doesn't mean the QX60 is now saddled with a CVT. The nine-speed auto carries over and yes, it can still pull 6,000 pounds with AWD and the tow package.  For 2025, all QX60s get a new fob with an optional automatic lock/unlock feature. The Black Edition (see the gallery above) will be available on Luxe models and includes the gloss black wheels, grille surround, roof rails and exterior badges; illuminated front and rear kickplates; "radiant" grille badge; welcome lighting and a black headliner. The base price of the Pure model is up just $550 from 2024, however the FWD variant of the Autograph has been dropped, making it $4,300 more expensive to get into the trim. However, the AWD variant only increases by $50. Here's pricing information for the entire 2025 QX60 lineup with front-wheel drive (including destination). AWD is $2,000 more on every trim but the Autograph, which bakes it in as standard equipment for 2025.  Pure: $51,550 Luxe: $58,150 Sensory: $60,450 Autograph: $67,500 Related Video:  2023 Nissan Pathfinder Rock Creek walkaround This content is hosted by a third party.
