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.

2020 Infiniti QX50 Luggage Test | Not infinity, but enough

The 2020 Infiniti QX50 is a comfortable five-seat luxury crossover that competes with the Audi Q5, Acura RDX, Volvo XC60, Lexus NX and others. If you’re interested in a QX50, itÂ’s probably got something to do with its impressive, technologically advanced VC-Turbo variable compression engine. It also has sumptuous swales of bodywork, a long list of driver-assist and safety features, and a solidly luxurious interior with a two-screen infotainment setup. The window sticker for the QX50 we drove recently in Essential trim says the seats were leatherette; if true, itÂ’s the most buttery fake leather out there. Still, the engineÂ’s the star. If performance is your only consideration, you can also get the VC-Turbo in the Nissan Altima sedan weighing 400 to 500-plus pounds less and at an MSRP starting $7,500 lower, a price spread that quickly expands as you option up the QX50. But if you want the QX50, itÂ’s probably because itÂ’s a crossover. You want to haul stuff. Which brings us to: luggage test. The QX50 has a cargo capacity of 31.1-31.4 cubic feet behind its raised back seat, which expands to 65.1 cubic feet with the rear seats down. That's more than most in its class, and the QX50Â’s cargo hold certainly looks big and usable enough. To test it, I had six roller suitcases at my disposal. Three would need to be checked at the airport, and one of those is particularly mondo (29x19x11, 26x17x10, 25x16x10). Three others were small enough to carry on (24x14x10, 23x14x11, 22x14x9). Several bags have four wheels that protrude and were counted in the dimensions. I lacked access to RiswickÂ’s wifeÂ’s fancy bag. An asterisk to all our luggage tests: Our crack team of test suitcases is empty. I know someone who can seriously overstuff a soft-sided bag, so depending on how you pack, your results may vary. The QX50 didn't arrive with a cargo cover, so that made things easier. My first stab at loading all those bags seemed promising — five out of six bags fit. Two of the big boys on edge, three carry-ons standing up. That would be one bag for every occupant, but hey, we can do better.  Standing them all up was the easy solution. This fits all six bags, and I'm certain they wouldn't fly forward in a hard stop. But the driver's rear view is impeded. I'd be annoyed to look back at this throughout a long trip. That biggest bag is the biggest offender, so can we just lay that one down? Sure, but we're back to just five bags fitting.

2014 Infiniti Q50 hits the web early, courtesy of... Infiniti

Well, what do we have here? It seems that Infiniti.ca, the official Canadian website of the Japanese automaker, accidentally published a load of 2014 Q50 images ahead of its official debut at the 2013 Detroit Auto Show.
As you can see in our high-res image gallery of screen shots above, the 2014 Infiniti Q50 carries along in the footsteps of the marque's current curvy design language. There's the requisite pinched chrome grille, upswept headlight clusters, and a hood with multiple flowing ridges, peaks and valleys.
As confusing as the newly Q-infused lineup may be on paper, there's simply no mistaking the new Q50 for anything but an Infiniti. You can expect a whole slew of images, facts, figures and commentary on the new luxury sedan on Monday, but until then, feel free to let us know what you think in the Comments.
