Infiniti G37 to be renamed Q40; new flagship sedan confirmed

Infiniti has already made it known that its aging G37 sedan will live on alongside the all-new Q50 through the 2015 model year, but little else for this sporty four door has been announced past the 2013 model year. As of this writing, there is no 2014 model shown on the company's consumer website. A new report from Car and Driver, however, indicates that like other models carried over to Infiniti's new naming convention, the four-door G37 will live out the rest of its days with a "Q" name after all.
Unlike the G coupe and convertible - renamed Q60 - the sedan will reportedly wear the Q40 designation until its ultimate demise. We reached out to Infiniti for more information, but a spokesperson only had this for us: "we have not provided any product details for post-2013 models. That will come at a later time." Previously, we had been told that the sedan would continue to live out its days under the G37 nameplate.
As for products that are actually new to the lineup, C/D says that the Q30 and the next-gen QX50 are both expected to arrive before the company launches a new range-topping flagship sedan as soon as 2016. Aside from a handful of reports suggesting this sedan exists (C/D says it's confirmed for production), there isn't much we know about it - including whether it will be called Q80, Q90 or something else entirely. It would appear there's plenty to look forward to from Infiniti's upcoming product lineup, and we are eagerly awaiting a 550-horsepower Q70 sedan and/or a production version of the Q50 Eau Rouge.

Chrysler, Nissan looking into claim that their cars are industry's most hackable

A pair of cyber security experts have awarded the ignominious title of most hackable vehicles on American roads to the 2014 Jeep Cherokee, 2014 Infiniti Q50 and 2015 Cadillac Escalade.
Charlie Miller and Chris Valasek are set to release a report at the Black Hat hacking conference in Las Vegas, Automotive News reports. The two men found the Jeep, Caddy and Q50 were easiest to hack based not on actual tests with the vehicles, but a detailed analysis of systems like Bluetooth and wireless internet access - basically, anything that'd allow a hacker to remotely gain access to the vehicle's systems.
Considering this lack of hands-on testing, the pair acknowledge that "most hackable" could be a relative term - they point out that the vehicles may actually be quite secure.

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."
