2015 Infiniti Q70 stretches out in NYC

Infiniti released its refreshed Q70 (the car formerly known as "M") in New York this morning. The luxury sedan is brings with it, quite literally, a big change: it's now the only vehicle in its segment to offer both long- and short-wheelbase options here in the US (other automakers do this in China). Currently, the two-wheelbase sedan strategy is exclusive to the ranks of fullsize players like the BMW 7 Series, Audi A8, etc.
Infiniti has elongated the standard Q70's wheelbase from 114.2 inches to 120.1 inches, in doing so lengthening the car 7.3 inches overall. For the sake of comparison, a standard wheelbase Audi A8 runs 117.8 inches, so the Q70 is no slouch. The extension mostly benefits rear-seat occupants, who are treated to an extra 5.6 inches of legroom. We think the enlargement improves the car's aesthetic, as well.
In addition to the long-wheelbase option, there are a few other tweaks in store for 2015. New head and taillights are the biggest changes, with full LEDs in the back and LED accents in front. Aspects currently seen on the smaller Q50 are evident, as well, such as the "double-arch" grille that comes with mesh-finish inserts. The fascia also includes a new front bumper with integrated foglights. Interior changes seem to be fairly minimal, but that's not necessarily a bad thing. The outgoing Q70 had a spacious (if dated), luxurious cabin with all kinds of high-quality materials.

Infiniti explored V8, diesel, hybrid power for Q50 Eau Rouge

Infiniti boss Johan de Nysschen "insists" the car be put into production.
Over the past few years, rumors have swirled about an Infiniti-badged, four-door version of the Nissan GT-R. Makes sense to us - Infiniti could certainly use a performance halo, and the seemingly forgotten IPL initiative hasn't exactly bore any interesting fruit. Enter the Q50 Eau Rouge, which recently debuted for a second time at the Geneva Motor Show packed with the 3.8-liter, twin-turbocharged heart of Godzilla itself.

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:
