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:

10 automakers sued over keyless ignitions

Keyless ignition has rapidly proliferated throughout the auto industry to become a fairly normal feature on new cars. It's supposed to offer the convenience of keeping the fob in your pocket and just pressing a button to drive away. However, ten major automakers are now being sued in US District Court over claims that the system is dangerous, Reuters reports. The suit alleges that people are forgetting to shut off the engine, and the lack of an idle timer is the cause for 13 deaths by carbon monoxide poisoning and multiple injuries. The suit currently includes 28 plaintiffs, according to Reuters, but the lawyers are asking for class-action status to potentially add many more. The case goes after a major swath of the industry, including BMW, Daimler, FCA, Ford, General Motors, Honda, Hyundai, Nissan, Toyota, and Volkswagen, plus their related brands like Acura, Infiniti, Mini, and Lexus. In all, over five million vehicles are affected. The assertion here is that people walk away from their vehicle without shutting it off because they believe the engine shuts off automatically. If parked in a garage, carbon monoxide can build up, leading to poisoning. The lawyers claim automakers know this is a problem and also cite 27 complaints to the National Highway Traffic Safety Administration about the issue, according to Reuters. The plaintiffs are asking for an automatic shut-off and damages from the companies. These concerns have come up before, though. Toyota previously faced a lawsuit over a carbon monoxide death after a woman accidentally left her Lexus running. Also earlier this year, GM recalled 64,186 examples of the 2011-2013 Chevrolet Volt because owners weren't shutting them off. The problem resulted in two injuries, and the company released a software update to limit the idling time.

Infiniti boss De Nysschen confirms next-gen Q60 Coupe, ponders high-performance variants

We've known since mid-December that Infiniti's new global model naming convention would turn the current-generation G37 Coupe into the Q60 Coupe starting next year, but we haven't been clear on whether the model-range-formerly-known-as-G would get a successor, especially as its volume has traditionally been a lot lower than its sedan counterpart.
Thankfully, Infiniti president Johann De Nysschen (above) has stepped up to confirm that the newly revealed Q50 sedan will receive a two-door counterpart, though perhaps not as quickly as some would like. According to an interview with Australia's CarAdvice.com, De Nysschen says "the coupe we can probably expect two-and-a-half to three years down the road." That news also suggests that if there's an eventual convertible version, that it's a long way off, too. Why so long? Infiniti has "a lot of priorities" - priorities that undoubtedly include an already-confirmed front-wheel-drive small hatchback/crossover.
The report also indicates that Infiniti has some aspirations for stretching its new Q50/Q60 range in a higher-performance direction to take on competitors like BMW and Audi, the latter being De Nysschen's former employer. There's far from a firm timetable offered, of course, with De Nysschen saying "someday in the future we will be able to offer more high performance versions [of Q50] than we have today... the dynamic capabilities of this platform are very significant. It can handle far higher power than the engines we are using at launch."
