Infiniti G37 to live on in showrooms alongside 2014 Q50

Infiniti is preparing to roll out its hotly anticipated 2014 Q50, a car that not only ushers in a new alphanumeric naming strategy, it ostensibly replaces the G37 as the brand's bread-and-butter sport sedan. That will happen, but not in the short-term, as the G37 will continue to be manufactured and sold alongside the Q50, at least for the rest of this year.
Infiniti spokesman Kyle Bazemore has confirmed to Autoblog that a decision is pending on how long to extend the G37 sedan's production run. "We're taking Q50 up a little bit, and that allows us to keep the G Sedan in the lineup... It [Q50] certainly started as a replacement, but it ended up being much more than that." Confusingly, Infiniti has already announced that the Q50 is to start at $37,605 (including $905 destination charge), yet the 2013 G37 is more expensive, starting at $38,255 delivered according to Infiniti's consumer website. Thus, a price drop on the G37 is likely coming in short order.
So why hold on to the older model? With the Q50 launching exclusively with V6 and Hybrid models (a turbo four and diesel are said to be in the cards down the road), Infiniti evidently feels it is risking leaving lower-end sales on the table. "There's a lot of movement with the [BMW] 320i and such, and this allows us a two-tier strategy to compete," says Bazemore. Keeping the G37 on tap at a lower price for fleet sale duty may also serve to protect the Q50 as it establishes itself on the market.

Infiniti Q Inspiration Concept shows a future with variable compression

For weeks, Infiniti has been teasing the Q Inspiration Concept ahead of its official debut at the Detroit Auto Show. Details were absent, but the design was clean, swoopy athletic. Not seeing any tailpipes on the rear end, we hoped it could sport some kind of electrified powertrain, but surmised that Infiniti could take the opportunity to further showcase its variable compression turbocharged engine technology. Now, Inifniti has officially taken the wraps off its Q Inspiration Concept, and has indeed chosen to use the stunning show car to demonstrate "near future applications" of the potent yet efficient VC-Turbo tech. VC-Turbo made its production debut in the 2019 QX50 at the 2017 Los Angeles Auto Show. Here, in the Q Inspiration, VC-Turbo allows Infiniti designers to make the most of the packaging, taking advantage of the compact powertrain to increase the size of the cabin while maintaining the footprint of a mid-size car. Electric automakers like Fisker, Lucid Motors and the like have been doing something similar with electric powertrains, but Infiniti's VC-Turbo allows the company to do something similar with technology that is ready for primetime, while still bridging the gap to more efficient future powertrains. VC-Turbo, as we've learned earlier, allows the engine to change and optimize compression ratios on the fly, between 8:1 for high-performance situations, to 14:1 for maximum efficiency. Mounted to the exhaust manifold integrated in the cylinder heads of the four-cylinder engine is a single-scroll turbocharger. The system, says Infiniti, provides the torque and response of a hybrid or turbodiesel powertrain without sacrificing efficiency. In the Q Inspiration, the power is directed to four wheels via a front-biased all-wheel-drive drivetrain. The system can direct torque to the rear wheels individually as needed. As a design study, the Q Inspiration is a success. The proportions and lines are sleek and attractive, accentuated by the car's white paint. There's kind of a lot going on up front, with a large "double-arch" grille at the leading edge. Everything behind that, though, looks particularly harmonious. Its elongated cabin and coupe-like dimensions help provide efficiency while maximizing headroom for the four occupants. It's a car that stands up to close inspection, as attention to detail makes it more interesting the closer you scrutinize it, inside and out.

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.
