2019 Infiniti QX50

The 2019 Infiniti QX50 has arrived. All new engine and a whole lot of new technology.

Infiniti's Detroit concept to be 'very, very, very, very close' to new Q60

Add one more vehicle to the tally of reveals slated for the 2015 Detroit Auto Show. Alfonso Albaisa, executive design director at Infiniti, has confirmed that the marque will be showing a new concept on January 13, the second media day. More importantly, though, this concept won't be another flight of fancy like many of Infiniti's past show cars. Instead, it will foreshadow the arrival of a replacement for one of its oldest vehicles, the Q60, a model better known as the G37 Coupe. "On January 13, you're going to see a concept car that's very, very, very, very close to the next Q60," Albaisa told Motor Trend. There isn't much to go on beyond that, sadly, although we are free to speculate. Infiniti's past would indicate that the Q60 would carry on its role as a two-door version of the Q50 sedan, with styling influenced by its four-door sibling. While that makes sense, there's also an argument to be made for departing from the Q50's styling in favor of a more expressive look that could allow the two-door model to stand out. Whichever avenue Infiniti chooses, we'll have an even better idea in just a few short months.

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.
