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.

2016 Infiniti QX60 Quick Spin

UPDATE: The original version of this story called Mazda's range-topping CX-9 the Platinum. This is incorrect. The top-of-the-line model will be called the CX-9 Signature. The story has been edited accordingly. When it comes to selling cars, getting customers into showrooms is half the battle. For Infiniti, one of its biggest draws is the QX60 – the three-row CUV originally known as the JX35, based on parent company Nissan's Pathfinder. QX60 buyers are young, female, and – most importantly – nine out of ten are new to the brand. The facelifted QX60, which was originally introduced in December, is here to maintain those stats. That's important, especially now, as increasingly premium mainstream offerings are proliferating throughout the market. This isn't a new trend – GMC's Acadia Denali predates the JX35, for example – but now the QX60 has to contend with things like the Ford Explorer Platinum, Honda Pilot Elite, Dodge Durango Citadel, and the upcoming Mazda CX-9 Signature. These vehicles are similarly priced, and offer similar capabilities and accoutrements to the QX60. Infiniti timed its QX60 update well, then, with a focus on aesthetics and maintaining the same driving dynamics. In the end, Infiniti offers a freshened CUV that should have no trouble keeping foot traffic flowing into the brand's showrooms. Driving Notes This might not be the popular opinion, but to our eyes, the QX60 is the best-looking product Infiniti currently makes (of course, the Q60 Coupe will trump that when it enters production). This thing has presence – we caught ourselves staring a number of times. But our lingering glances make sense when you look at the QX60 alongside the original JX35. The former lacked real hard edges or sharp details. Look at this comparison gallery to see the difference. What's remarkable is that Infiniti made this big visual improvement as part of a mid-cycle refresh. Yes, the front and rear fascias, headlights, and taillights were swapped out, but the cumulative effect is a dramatically more premium and refined aesthetic. We dig the way the dark grille integrates more neatly with the lower intake, and the LED running lights give the sharper, more aggressive headlamps a piercing effect. Out back, a revised rear bumper and a wider chrome strip produce a more substantial, upright appearance. These are little changes, to be clear, but taken as a whole they feel far more sweeping. The same can't be said of the cabin.

Infiniti QX70 is fini, for now

We knew it first as the FX, debuting in 2003 as a bulgingly macho SUV/crossover thing with an impossibly long hood. It was quick and powerful, and lower-slung than typical SUVs, more like a tall wagon. Infiniti later dialed the cartoonishness of it back a few notches and started calling it the QX70. Now, the QX70 is going to take a little break, disappearing from the lineup for a few years while QX50 and QX80 redesigns are rolled out. The QX70 is sporty, with a 325-horsepower 3.7-liter V6. But it's an aging model and a bit of a slow seller - last year, Infiniti moved one-seventh as many QX70s as it did its kid-hauling cousin the QX60 - which seats more people (seven, to the QX70's five) and is less expensive. The QX70 was once popular like that, selling 30,964 as the FX in 2004. But that was long, long ago. Last year it sold 6,261. The QX70 nameplate is expected to be back in 2021 or 2022, in a redesign based on the Nissan Murano and built at Nissan's plant in Canton, Miss.
