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:

2019 Infiniti QX50 starts fresh with a new face and trick engine

Last week, Infiniti rolled out the refresh of the big daddy QX80 in Dubai. At this year's Los Angeles Auto Show, the Japanese automaker is poised to reveal something that's bound to be far more mainstream: the 2019 Infiniti QX50 and its trick variable compression turbocharged engine, or VC-T. In addition to the new engine, the QX50 drops rear-wheel drive in favor of an all-new front-wheel-drive platform and gets the new ProPilot assist technology that debuted on the Nissan Leaf. The QX50 may be the headliner, but the engine is the really interesting bit. This 2.0-liter turbocharged inline-four can adjust the stroke of the pistons on the fly, varying the engine's compression from 8:1 to 14:1, and giving the new midsize crossover improved efficiency and diesel-like torque. It's rated at 268 horsepower and 280 pound-feet of torque, down 57 horses but up 14 pound-feet. Front-wheel-drive models hit 60 mph in 6.7 seconds. That drops to 6.2 seconds with all-wheel drive. Combined fuel economy is 27 mpg for front-wheel-drive QX50s and 26 mpg for all-wheel-drive variants, both up from the abysmal 20 mpg combined rating of the current model. Power is sent through a continuously variable transmission. If it's like other Nissan and Infiniti CVTs, it will be inoffensive if a bit lifeless. We've covered the details of this powertrain extensively already, but it's great to see companies giving more life to the internal combustion engine. The new platform marks a big improvement over the outgoing QX50 in terms of platform rigidity and space efficiency. Rear-wheel drive might be fun, but it's never ideal from a packaging perspective. Cargo capacity is up from 31.6 cubic-feet to 37 cubic-feet. With the seats down, the space expands to 60 cubic feet, up from 50.1 cubic feet. That's not exactly class-leading, but it's no longer among the class-worst. The 2019 QX50 will use a new type of high-tensile steel, improving torsional rigidity by 23 percent and shaving overall weight. The styling falls in line with most other Infiniti products. The outgoing model had a bit of an identity crisis, looking more like a lifted wagon than a fully-realized crossover (it was, after all, essentially a G35/G37 wagon). This new one has much more conventional SUV proportions. In fact, it looks like a 7/8-scale version of the new QX80 with a front-wheel-drive profile. That's either good news or bad news, depending on where your tastes fall.

2014 Infiniti Q50 hits the web early, courtesy of... Infiniti

Well, what do we have here? It seems that Infiniti.ca, the official Canadian website of the Japanese automaker, accidentally published a load of 2014 Q50 images ahead of its official debut at the 2013 Detroit Auto Show.
As you can see in our high-res image gallery of screen shots above, the 2014 Infiniti Q50 carries along in the footsteps of the marque's current curvy design language. There's the requisite pinched chrome grille, upswept headlight clusters, and a hood with multiple flowing ridges, peaks and valleys.
As confusing as the newly Q-infused lineup may be on paper, there's simply no mistaking the new Q50 for anything but an Infiniti. You can expect a whole slew of images, facts, figures and commentary on the new luxury sedan on Monday, but until then, feel free to let us know what you think in the Comments.
