Infiniti keeps us on our toes for Q50 Eau Rouge

If you've been watching the evolving rapprochement between Infiniti and Red Bull Racing, and have wondered what the point was if the Japanese automaker didn't capitalize on its expensive collaboration with the world-champion Formula One team, then Infiniti may finally have the answer come the Detroit Auto Show next month.
That's where Nissan's premium division is set to unveil the Q50 Eau Rouge concept, a show car set to showcase its F1 involvement in the form of a jazzed-up sports sedan. We still don't have much to go on in terms of what the concept car will actually entail beyond a body kit, but Infiniti has launched a dedicated website for the reveal and with it, this teaser video. It still doesn't tell us much, but it's a cool animation just the same, so check it out below.

Infiniti confirms new "premium compact" to be built in UK

Aside from certain naming-related news, Infiniti has actually had some decent product news to announce this week. The company's president, Johan de Nysschen, alluded to a new 550-horsepower performance sedan, and now the automaker has confirmed that a new "premium compact" will go into production in 2015. Based on the fact that this new model will be built alongside the Nissan Leaf at the automaker's Sunderland, UK assembly plant, we could only hope that it's a production version of the LE Concept (shown above).
Sunderland already produces Nissan products like the Qashqai, Juke and Note, and as a part of an investment of 250 million British pounds (around $406 million USD) for the new model, the plant would add an extra 280 jobs with the capacity to build 60,000 of the new Infinitis annually. Adding the premium compact at Sunderland means that Infiniti will have to change its plans for another new model, a bigger "C-segment hatchback," which could very well be a production version of the Etherea Concept.

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. You can view how it works in motion via the video below. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. 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.
