US-built Infiniti Q50 engines to go into Euro-only cars

Back in March, Infiniti announced that it would be adding a 2.0-liter, turbocharged four-cylinder to its Q50 line for European and Chinese buyers. Now, we know where that engine will be built.
Nissan's Decherd, TN facility will receive the $319-million investment, which will see a separate, dedicated line for the Infiniti engines. According to Automotive News, this is more than a line running alongside the Nissan operations - the Infiniti facility will sport its own unique architecture and interior lighting, in a bid to distinguish the premium line from its mass-market parent company.
The logistics of all this do seem, on the surface, quite screwy. Building a new engine on one continent for a car built on another that will eventually go on sale on a third doesn't seem too bright, although there is a catch here. The new engine will also find its way into the Mercedes-Benz C-Class, which will kick off production in Vance, AL later this year.

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.

Infiniti previews a new... something

Sometimes we get a teaser image and accompanying statement where we can at least surmise what the automaker is up to. This is not one of those times.
The automaker, in this case, is Infiniti, and the teaser image shows only a grille with a similar shape to what you'd find on most of the company's products, albeit with a curvier mesh. Which isn't much to go on, really, and the accompanying statement (which you can read below in its forty-word entirety) doesn't give us much more. All it says is that the vehicle in question - which we'll wager is a concept car instead of a production debut - has "style and substance" embodied in a "vision... on a scale not seen before" from Infiniti.
Given the French peppered into the release and the encroaching chronological proximity of the Paris Motor Show, we'd guess that's where Infiniti will reveal this latest but of inspiration, but just what form it will take is still a mystery.
