New details emerge on Inifiniti QX50’s unique new variable-compression engine

Infiniti will release the world's first production variable-compression engine when it releases the 2019 QX50 midsize SUV sometime next year. Now we have some new details on the innovative new engine, which Infiniti is calling VC-T, for Variable Compression Turbo, after the luxury brand offered a prototype test drive. We wrote extensively about the complicated technology underpinning the new engine last year. It's the latest novel development that could represent a range-extender, if you will, for the embattled internal combustion engine in an era when automakers and governments are shifting their focus to electric vehicles. The VC-T is a new inline-four, 2.0-liter that combines the power of a high-performance turbo gasoline engine with the torque and efficiency of an advanced diesel engine, but without the latter's notorious emissions. It features the ability to seamlessly raise or lower the stroke of the pistons in the combustion chamber, depending on the driving conditions it detects and inputs from the driver, to select the best compression ratio—anywhere between 8:1, typical for high-performance engines, and 14:1 for high efficiency. In essence, it delivers the performance of a V6 but is much more efficient, with improved fuel efficiency of between 10 to 15 percent with its best competitors, per Car and Driver.

It's also quieter, more lightweight and compact than V6 engines with comparable power outputs, estimated at 268 horsepower and 288 pound-feet of torque. In a prototype test drive, Car and Driver writes that the engine "felt very conventional" and responsive, with strong and smooth acceleration. "The only indication you have that the compression ratio is changing is from an indicator in the instrument cluster next to the boost gauge." The engine is expected to deliver fuel economy gains of 27 percent in combined city-highway EPA rating over the outgoing QX50, which had a 3.7-liter V6. The 2019 model, fitted with the VC-T, should get about 26 mpg in combined fuel economy, and it will get to 60 mph almost one second faster than its four-cylinder counterparts, Nissan's chief powertrain engineer, Shinichi Kiga, told Automotive News. The VC-T engine is the result of 20 years of development spanning more than 100 prototypes and around 300 patents at Nissan.

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 QX Inspiration Concept SUV may be the most Japanese thing in Detroit

Infiniti is following up its Q Inspiration Concept from the Detroit Auto Show last year with a QX Inspiration Concept for 2019. Unlike the Q Inspiration from last year ( VC-Turbo engine), this one is fully electric. That said, it does sport a similar design language. This QX concept is meant to preview an upcoming midsize electric Infiniti SUV. Since it's powered by an electric powertrain, there's no need for a grille. Infiniti decided to take the opportunity to spell its name out in big and bold letters across the bow instead. The proportions are obviously concept-car-like with a high beltline and squashed rear-end. Straight lines and muscular curves accentuate the car's stance nearly everywhere you look — somehow we still didn't escape the plastic wheel arches breaking up the pretty white paint and surrounding the 22-inch wheels.

Infiniti emphasizes that it used Japanese "Ma" styling, which puts an emphasis on negative space. Take a look through the photos yourself to see if you think Infiniti succeeded at utilizing the design mantra of "white space" on this SUV. One neat feature you'll easily be able to decipher on the exterior is the use of Japanese red cedar slats on the roof. You can see straight out of the car from inside, and it offers a bit of contrast color-wise. A lot of the magic is contained in the interior of the QX Inspiration, though. The first thing you'll see is the pillar-to-pillar screen that's finished in gold-tinted glass. Remind anyone of Byton? As if that wasn't enough screen, Infiniti also put a screen in the square steering wheel, too. The center console is made using marble, extending all the way back to the rear seats. White, suede rhombus panels serve as the Infiniti's floor that also features gold inlays. Infiniti takes advantage of the electric car benefit of a flat floor for extra interior space — the battery sits low under it. Infiniti QX Inspiration Concept View 24 Photos It also uses the popular concept-car trick of rotating seats to make ingress and egress easier. The same tech was revered in the 1960s. Infiniti says it intentionally left out any technology from the backseat so as to give the cabin a more natural and authentic appearance in pursuing the Japanese appreciation of nature and craftsmanship.
