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:

The Nissan Patrol may become America's next Armada

Plausible rumors are swirling that the Nissan Patrol, the Land Cruiser rival sold outside of North America, might come to the US as a replacement for the unrelated Nissan Armada. That large SUV's future was left ambiguous after the news of the Xterra's discontinuation, as Nissan's press release ominously promised information on the Armada "at a later date" without further elaboration. That left us scratching our heads and thinking that, perhaps, it would be quietly killed off in the future. If the rumors are true, it will be. And then it will be reborn. It'll join its old platform-mate, the Infiniti QX80, on the Patrol platform. The QX abandoned its Titan-based platform in 2011, becoming the Patrol-based QX80. So you can think of the Armada as catching up, a few years late. The QX80 was refreshed last year, a mainly cosmetic nip-and-tuck. The Infiniti utilizes the 5.6-liter, 400-hp V8 and a 7-speed auto, so it's a safe bet that this powertrain will make it into the Armada version. Less likely, but plausible, would be the availability of the new powertrains intended for the Titan XD and upcoming lower-grade Titans. The massive SUV market tends to be a bit conservative, so the Cummins diesel V8 that's the sole engine in the Titan XD right now seems unlikely. The forums are abuzz with a photo of what's purported to be a leaked marketing image of the new Armada, so head to this TitanXDForum thread if you'd like to see what that's about. (Spoiler: it looks a lot like the Patrol above, minus some of the Nismo flair.) Related Video:

2014 Infiniti Q50 and Q60 Coupe and Convertible order guides leaked

The pricing and configurator for the 2014 Infiniti Q50 were revealed a couple months ago, and now InfinitiQ50.org has uncovered leaked order guides for Infiniti's all-new luxury sedan as well as the renamed Q60 Coupe and Convertible.
From the looks of things, if you'd like a rear-wheel drive Q50, you may have to have to special order it. All three Q50 RWD models say "Sold Order Only" on the model, mix and MSRP page. As for the Q60 models, the only differences for the 2014 model year - aside for the new name, of course - are related to exterior coloring. A new Venetian Ruby hue is being added to the palette.
