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.

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:

2022 Infiniti QX55 marks the company's foray into crossover 'coupes'

Using a formula proven by the major German luxury car companies, Infiniti is now getting in on the crossover "coupe" game. The 2022 Infiniti QX55 takes the QX50 small crossover and adds a fastback roofline for a sportier look. Infiniti says the design makes the QX55 a spiritual successor to the FX crossover of the mid-to-late-2000s and early 2010s. We're not sure if the mechanical bits live up to the rear-drive-based FX chassis, but the low roof and curvy body do share a connection to that old SUV. In fact, the QX55 looks rather striking, and the flowing lines work nicely with the simple, arcing roof. Some other small tweaks to the base styling emphasize the QX55's style focus including a more pronounced grille with larger air intakes surrounding it at the front. At the back, the license plate mount has been moved to the bumper, allowing for prominent Infiniti lettering on the hatch. Additionally, 20-inch wheels are a standard feature on all QX55 models. The rest of the QX55 is basically the same as the QX50. It shares the turbocharged, variable-compression engine making 268 horsepower and 280 pound-feet of torque. It's mated to a CVT and all-wheel-drive, which is standard on all QX55 models. The interior is carry-over with dual infotainment screens and an asymmetric, driver-focused dash design. Like the QX50, it can be slathered in two-tone leather for a very premium feel. The debut vehicle features a bold black and red color combination. The QX55 goes on sale this coming spring. It will be available in three trim levels: Luxe, Essential and Sensory. Pricing hasn't been announced, but expect it to be a bit more costly than the equivalent QX50. For reference, a QX50 Luxe with all-wheel-drive starts around $44,000, and at the other end of the spectrum is the QX50 Sensory with all-wheel-drive starting at around $53,000. Related Video:
