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:

Infiniti Q30 Concept might be the cleverest Q model yet

When we first got official word of the Infiniti Q30 Concept, the Japanese automaker said that the crossover's "harmonious contrasts and dissymmetric philosophy" would "make an emotional connection with customers spontaneously." Now, we might not be heads of design studios or directors of marketing departments, but we're pretty sure we can translate that to: "The production Q30 will compete with the Audi A3 and Mercedes-Benz CLA-Class."
In all seriousness (if we can say that of a concept car painted a sort of rose metallic), the Q30 concept looks fetching here in Frankfurt; its rather convoluted and flowing bodywork just carried off successfully because of its grownup hatchback proportions and, frankly, huge wheels. The Q30 could seemingly slot into the current, attractive Infiniti range of production cars and not look amiss (though we'd prefer a color palette that looks a little less like Grandma's sitting room sofa).

Infiniti G37 to live through MY 2015, sell alongside Q50

Infiniti has officially confirmed news we broke last month about its G37 sedan - that it will live on in showrooms alongside its erstwhile replacement, the 2014 Infiniti Q50, a model that goes on sale this week. And it's sticking around for quite a while - it will be sold through the 2015 model year.
In order for the G37 and Q50 to not rub shoulders, Infiniti is rolling out an amended G lineup, complete with lowered pricing. The G37 will stick around in Journey and all-wheel drive trims, both powered by the same 3.7-liter VQ-Series V6 engine, and only two option groups will be available, Premium and Navigation. The 2014 G37 Journey will start at $32,550, while the G37 Sedan AWD will run $34,150 (both are subject to a $905 destination fee).
The 2013 G37 had been priced from $38,255 delivered as of earlier this week, so the price drop is significant, likely bringing the base MSRP more in line with where transaction prices had been on the aging model. The new pricing, which takes effect August 6, should also allow the G37 gain consideration amongst shoppers of smaller-engined rivals like the BMW 320i while the Q50 waits on a turbocharged four-cylinder and diesel engine from Daimler. For comparison's sake, the larger, more tech-rich Q50 will start at $37,605 delivered.
