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.

Zombie cars: A dozen discontinued vehicles people still buy new

Car models come and go, but as revealed by monthly sales data, once a car is discontinued, it doesn't just disappear instantly. And in the case of some models, vanishing into obscurity can be a slow, tedious process. That's the case with the 12 cars we have here. All of them have been discontinued, but car companies keep racking up "new" sales with them. There are actually more discontinued cars that are still registering new sales than what we decided to include here. We kept this list to the oldest or otherwise most interesting vehicles still being sold as new, including a supercar. We'll run the list in alphabetical order, starting with *drumroll* ... BMW 6 Series: 55 total sales BMW quietly removed the 6 Series from the U.S. market during the 2019 model year. It had been available in three configurations, a hardtop coupe, a convertible and a sleek four-door coupe-like shape.   BMW i8: 18 total sales We've always had a soft spot for the BMW i8, despite the fact that it never quite fit into a particular category. It was sporty, but nowhere near as fast as similarly-priced competitors. It looked very high-tech and boasted a unique carbon fiber chassis design and a plug-in hybrid powertrain, but wasn't really designed for maximum efficiency or maximum performance. Still, the in-betweener was very cool to look at and drive, and 18 buyers took one home over the course of 2021.   Chevy Impala: 750 total sales The Impala represented classic American tastes at a time when American tastes were shifting away from soft-riding sedans with big interior room and trunk space and into higher-riding crossovers. A total of 750 sales were inked last year.   Chrysler 200: 15 total sales The Chrysler 200 was actually a pretty nice sedan, with good looks and decent driving dynamics let down by a lack of roominess, particularly in the back seat. Of course, as we said regarding the Chevy Impala, the number of Americans in the market for sedans is rapidly winding down, and other automakers are following Chrysler's footsteps in canceling their slow-selling four-doors. Even if Chrysler never really found its footing in the ultra-competitive midsize sedan segment, apparently dealerships have a few leftover 2017 200s floating around. And for some reason, 15 buyers decided to sign the dotted line to take one of these aging sedans home last year.

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.
