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 boss De Nysschen confirms next-gen Q60 Coupe, ponders high-performance variants

We've known since mid-December that Infiniti's new global model naming convention would turn the current-generation G37 Coupe into the Q60 Coupe starting next year, but we haven't been clear on whether the model-range-formerly-known-as-G would get a successor, especially as its volume has traditionally been a lot lower than its sedan counterpart.
Thankfully, Infiniti president Johann De Nysschen (above) has stepped up to confirm that the newly revealed Q50 sedan will receive a two-door counterpart, though perhaps not as quickly as some would like. According to an interview with Australia's CarAdvice.com, De Nysschen says "the coupe we can probably expect two-and-a-half to three years down the road." That news also suggests that if there's an eventual convertible version, that it's a long way off, too. Why so long? Infiniti has "a lot of priorities" - priorities that undoubtedly include an already-confirmed front-wheel-drive small hatchback/crossover.
The report also indicates that Infiniti has some aspirations for stretching its new Q50/Q60 range in a higher-performance direction to take on competitors like BMW and Audi, the latter being De Nysschen's former employer. There's far from a firm timetable offered, of course, with De Nysschen saying "someday in the future we will be able to offer more high performance versions [of Q50] than we have today... the dynamic capabilities of this platform are very significant. It can handle far higher power than the engines we are using at launch."

Leopard walks in, shuts down a Mercedes-Benz plant

In recent months the auto industry has seen plant closures due to a host of reasons — parts shortages, recalls, natural disasters, and even a once-in-a-lifetime pandemic. Now it can add to that list the threat of an invading leopard. A Mercedes-Benz factory in Pune, India, was forced to halt production for a few hours when a wayward jungle cat wandered into the facility, When the 3-year-old male leopard was spotted inside the manufacturing unit of the factory, it caused a panic among workers, according to a release by rescue organization Wildlife SOS discovered by The Drive. The site was shut down for about six hours as a Wildlife SOS rapid response team from the Manikdoh Leopard Rescue Centre and the State Forest Department safely removed the curious cat.

The team's veterinary officers Dr. Nikhil Bangar and Dr. Shubham Patil carried out the rescue operation, tranquilizing the feline and loading it into a wildlife carrier. The rescue took about four hours, and Wildlife SOS reports that neither the creature nor any workers sustained injuries. The leopard was released back into the wild.  No one is quite sure how it got onto the factory grounds, but Wildlife SOS says that the forests in the surrounding region have one of the highest densities of leopards in the world. It's also suffering from rapid deforestation. That encroachment by humans has led to a decrease in the leopard's natural prey as well, so wildlife experts think it may have been looking for food.  The Mercedes plant builds the Maybach S 560, S-Class, E-Class Long Wheelbase, C-Class, CLA, GLA, GLE and GLS for the Indian market.  We have a different theory. We believe that the cat was seeking to set the record straight with Mercedes. When the S 65 AMG debuted, Mercedes claimed it featured the world's first Road Surface Scan technology to detect pavement undulations and adjust suspension damping accordingly. The only problem with that claim: Nissan had the technology some 30 years earlier in several mid-80s models, including the Maxima and Japan's version of the Infiniti M30, which was called — you guessed it — the Leopard.
