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 QX70 drops V8 for 2015, holds line on pricing

QX70 was the only application for the 5.0L, making it a tough sell in the boardroom.
It was always easy to chuckle a bit at Infiniti's branding of its FX crossover as a "bionic cheetah" - until you drove the thing. It was something of a revelation when it came on the market in late 2002 - certainly visually, but also in terms of performance, particularly in V8 guise. The Porsche Cayenne burst on the scene at the same time, and between the two of them, they vividly illustrated that the idea of a performance utility vehicle wasn't the oxymoron it first appeared to be.

Infiniti to get Leaf-based electric sedan after all

Infiniti suffered a huge blow a few weeks ago when CEO Johan de Nysschen jumped ship after two years on the job to take the helm at Cadillac. As boss, he spearheaded change within the Japanese luxury brand and was among the biggest champions of the Q50 Eau Rouge. However, the company is far from sunk. Plans put in place prior to de Nysschen leaving are still on the table, according to Nissan product planner Andy Palmer to Automotive News, and that could mean a rosy future for the once AWOL LE sedan (pictured above) and other models.
Back in 2012, Infiniti promised that it would have the LE on the market as a premium electric sedan by 2014. It was supposed to share the battery pack with the Nissan Leaf but with a more powerful, 134-horsepower motor. But have you seen one on the road recently? The luxury EV was eventually shelved, but de Nysschen pledged the idea wasn't dead. Maybe now is a better time for it. According to Automotive News, the LE is rescheduled to launch in 2017 or 2018. The latest version would use the Leaf platform but with a more potent, next-gen battery to give it a range over 90 miles.
Of course, the LE isn't the only thing on the way from Infiniti; it also appears to be planning a two-pronged approach for small cars. Palmer recently tweeted that the company would build the forthcoming Q30 hatchback and QX30 crossover in the UK in 2015. Additionally, the automaker is firing up a new joint venture factory in Mexico with Mercedes-Benz; building compact models there starting in 2017. According Automotive News, the Mexican-built models will be more US-focused while the UK-built ones will appeal more to Europeans.
