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 puts EV plans on hold again

Think of it as the green-automotive industry's version of Groundhog Day. Nissan's Infiniti division is putting plans for its first mass-production electric vehicle on hold. Again. The Infiniti LE, whose concept version was unveiled 2012's New York Auto Show, is again being put up on the proverbial blocks, USA Today says, citing a presentation by Infiniti executive Michael Bartsch at a recent company event in Detroit. Essentially, the Nissan division has bigger fish to fry, in the form of boosting overall Infiniti sales, and doesn't yet want to put the effort into introducing the Infiniti LE. The Infiniti EV plans were first postponed by then-Infiniti President Johan de Nysschen during the summer of 2013, as de Nysschen wasn't quite buying into Nissan boss Carlos Ghosn's ambitious electric vehicle sales projections. De Nysschen resigned last summer to join General Motors' Cadillac division. One issue may be the fact that the Infiniti wouldn't be all that different from the Nissan Leaf. Despite the fact that US sales of that EV surged 34 percent last year compared to 2013, to 30,200 vehicles, an Infiniti version was apparently not enough of a selling point within the company. While the Infiniti is sportier looking than the Leaf and would boast inductive, wireless charging, it would have a similar power output and single-charge range as the Leaf.

This is the 2017 Infiniti Q60 Coupe totally exposed

Right about now, Infiniti's holiday card to Autoblog is going to get "lost in the mail." That's because we're going to spoil the automaker's next big debut nearly two full months ahead of schedule. Oops. What you see above comes from a promotional shoot for the new Q60 coupe. The photos taken here will probably serve as the official images when the new coupe bows in January at the 2016 Detroit Auto Show. The look is more or less what we expect, serving as a literal translation of the Q60 coupe concept that debuted last year in Detroit. That means it's darn handsome. The front fascia is bold, with Infiniti's trademark grille dominating the nose. As we predicted in our most recent round of spy photos, the Formula One-inspired front bumper has been ditched in favor of a more conventional unit, likely owing to Infiniti parent Renault-Nissan's pending divorce from the Red Bull Racing team. This is not a bad thing. There was just too much Mercedes-Benz SLK in the concept's front bumper. The pert tail features a remarkably short deck and an aggressive roofline, although we aren't sure how the company's heavily kinked beltline works on a two-door model. The profile is also highlighted by a set of vents just aft of the front axle. Overall, we're finding the new Q60 coupe to be a worthwhile alternative to the BMW 4 Series, Audi A5, Lexus RC, and the upcoming Mercedes C-Class coupe in terms of aesthetics. As previously reported, the most powerful Q60, likely featured here, will be offered with a 3.0-liter, twin-turbocharged, 400-horsepower V6. A 2.0-liter turbo pilfered from Mercedes will serve as the base engine. As for the cabin, we unfortunately don't have much to show you (we need to leave something for Infiniti to show in Detroit, right?). We can tell you that the overall cabin should be reminiscent of the Q50 sedan, and the Q60 isn't likely going to depart much from the controls and infotainment on its four-door sibling. Related Video:
