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 teases QX Monograph concept for Pebble reveal

Infiniti is planning on showing a new concept car during Monterey Car Week called the QX Monograph. In case you lost track of time, that’s next week, as the concept car will officially be unveiled on Thursday, August 17. Infiniti is planning on holding a press conference at The Lodge at Pebble Beach where Alfonso Albaisa, senior VP of design, will present the vehicle. Infiniti says the new concept will showcase the “future direction of InfinitiÂ’s design direction.” A single teaser image gives us a glimpse of the grille and the Infiniti logo on the front. There isnÂ’t a lot Infiniti is saying about the QX Monograph yet, but weÂ’re told it features “digital piano key” lighting, bold proportions and the aforementioned double-arched grille. Of course, since itÂ’s a QX model, we should also expect it to be an SUV concept and not any other body style. Beyond the concept car, Infiniti says itÂ’s bringing never-before-seen quarter-scale design models from Nissan archives to display publicly. In total, four of these models will be shown, including the 1916 DAT 41, 1966 Prince Skyline 2000-GTB, 1970 Nissan Skyline H/T and the 1995 Nissan Skyline GT-R.
