Infiniti bringing Q50 Eau Rouge to Geneva, now with engine [w/video]

During last month's Detroit Auto Show, Infiniti rolled out the lustrous Q50 Moulin Eau Rouge concept - a preview of what could be a solid performance offering from Nissan's luxury arm. Problem is, the car shown in Detroit was all show and no go - literally.
Infiniti was keen to talk about how the Eau Rouge would feature "a big personality, V-cylinder engine with forced induction" with "over 500 horsepower and 600 pound-feet of torque," but the showcar had no such powerplant underhood. In fact, it didn't have any powerplant under the hood at all. That'll change next month, however, as Infiniti has now confirmed that it will bring the Q50 Eau Rouge to the Geneva Motor Show in March, complete with the promised "big personality" engine.
"Our engineers have perfectly captured the tone of Infiniti's take on premium performance, and a car that is as impressive as the Q50 Eau Rouge sounds is surely a car to challenge performance cars in the premium sector," said Infiniti's President, Johan de Nysschen. Regarding that sound: he ain't foolin' - the automaker has released a teaser video that gives us our first listen at what the Q50 Eau Rouge will sound like once its powerplant is nestled underhood. Scroll down to give it a watch - err, listen - and have a look beyond that for the company's official press blast.

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.
