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 Infiniti Q60 Black S gets an F1 KERS system

This is the Infiniti Q60 Black S that will be debuting at the Geneva Motor Show, sporting some intense bodywork and an F1-inspired powertrain. It exists to draw a closer parallel between the Renault F1 program and the Infiniti brand – a relationship that's surely easier to understand in Europe than it is here, but so be it. Other than the wild bodywork, which includes a heavily sculpted front fascia, bigger side sills, two howitzer-sized exhaust pipes, and a massive rear wing, there's the F1-inspired KERS system. Exactly what that will be is up in the air; the F1 system is complex and expensive. While Infiniti says they want to engineer a road-going solution that's as similar as possible to the F1 KERS system, it's likely it'll be watered down a bit for production. View 12 Photos All in all, the 3.0-liter, twin-turbo V6 and the KERS system should combine to produce about 500 horsepower. That's all well and good, if it makes it out of concept car purgatory. Remember the Q50 Eau Rouge, the last Infiniti that got car enthusiast's undivided attention? Well, it got canceled. We're not sure what the appeal of an F1 tie-in would be to American shoppers, so who knows if the Black S will emerge as a rest-of-world special, or at all. In any event, we should have more details around Geneva, so stay tuned.

Grand Prix of the Americas, Day 1 Recap: a city arose in the fields, and it was good

The Circuit of the Americas is the miracle in the fields, the track that no one thought would be finished in time to hold its appointed race. But the Texans got past the turmoil, and even though the heavy machinery was still working on dirt roads as July, come November 18 there was a beautiful, and completed, Formula 1 facility for Travis County to call its own. It was dusty, sure. But it was done, and F1 could come to town.
Infiniti, sponsors of Red Bull Racing, invited Autoblog to watch the first grand prix in America since 2007, and the first GP on a dedicated F1 course since the Phoenix street circuit in 1991. Here's a little recap of what we saw and fount out on day one.
