Popular Science magazine's Best Of What's New 2012 all ate up with cars

Popular Science has named the winners in its Best of What's New awards, the victors coming in the categories of aerospace, automotive, engineering, entertainment, gadgets, green, hardware, health, home, recreation, security and software. The automotive category did not go wanting for lauded advancements:
Tesla Model S: the Grand Award winner for being "the standard by which all future electric vehicles will be measured."
BMW 328i: it's 2.0-liter turbocharged four-cylinder gets called out for being more powerful and frugal than the six-cylinder it replaces.

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 Q50 Eau Rouge racing toward Detroit with Red Bull in its veins

There are several ways an automaker can get into Formula One racing. It can start its own team from scratch (like Toyota did in 2002), it can buy an existing team (like BMW did with Sauber in 2005) or it can supply engines to other teams (as so many manufacturers have done over the years). Infiniti chose another direction and opted to sponsor the world-champion Red Bull Racing team.
Infiniti has undoubtedly poured millions into its partnership with Red Bull since it started in 2011, but aside from the Sebastian Vettel edition FX (which technically emerged from the company's sponsorship of the driver as separate from the team), the tie-in has yet to translate into a Red Bull-tuned (or at least -inspired) Infiniti for the road. But that's just what Nissan's premium brand has in store for us at the upcoming Detroit Auto Show in January.
Well, almost, because the concept just announced is still a step or two away from reaching your local Infiniti dealership, but here it is just the same. It's called the Q50 Eau Rouge, and it's based on the company's latest tech-laden sports sedan. It takes its name, of course, from the famous uphill section of the Spa-Francorchamps circuit where Sebastian Vettel won the Belgian Grand Prix earlier this year, but Infiniti isn't telling us much more than that.
