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.

Nissan built a Skyline that you can almost live in

The Infiniti Q50 is pretty long in the tooth, but parent company Nissan is still trying to keep things interesting. In Japan it's sold as the Nissan Skyline, and a new concept based on the luxury sedan converts it into a space you could actually live in.  The cumbersomely named Nissan Skyline Contemporary Lifestyle Vehicle Concept adds a slew of convenience features that you should never use while driving. When parked, however, they turn your car into a little living room. For example, there's a little smartphone holder that folds out from the steering wheel so you can prop your screen up and watch a movie. If that's too small a viewing surface for you, the center infotainment touchscreen can be removed from its dashboard perch and used as a tablet. And if that's still too small for you, there's a screen mounted in the headliner above the rear seats. How do you watch a screen in that location? Glad you asked. The front seats, headrests, rear bench and passthrough to the trunk all lay flat in one uniform surface sleeping area. When lying down, the screen will be right above your head. And should you get cold, the driver's door panel pops open to reveal a blanket while the cupholder has a heating element to keep a beverage warm. On the flip side, should you get hot, a button on the inside B-pillar activates the air conditioning so you don't even have to sit up to access the climate control. While awake, you can avail yourself of multiple table surfaces located around the cabin. One folds out from the center console like on a business class airplane seat. A detachable sun visor also turns into a table. Then get a little work done by plugging in to either the 100-volt outlet in the passenger side mirror or an on-board portable battery. Obviously you wouldn't want to get your nice jacket wrinkled as you lounge in the car, so the grab handle above the door expands into a hanger wide enough to keep your coat uncreased. Other clever storage options include an umbrella compartment in the door sill, a bin located in the headrest, and a hands-free kick-activated locker below the rear bumper where a diffuser would reside. Perhaps most superfluous of all is a trash receptacle located in the driver's side mirror. You'd still have to empty it when full, but at least smelly garbage would be outside the car. Oh yeah, there's one final viewing surface, the largest of them all.

Infiniti Q50 Eau Rouge portends seriously powerful future sports sedan

"If we built this car I would expect it to feature over 500 horsepower and 600 pound-feet of torque."
Eau Rouge is a notoriously difficult turn at Belgium's Spa-Francorchamps Circuit that is capable of striking fear into the hearts of the most hardened driver. Naming a car after something so terrifying, therefore, strikes us as a rather poor idea.
