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 to launch first electric car, to be made in China

BEIJING — The first electric car for Nissan's premium brand Infiniti will be a sporty sedan produced in China, the Japanese carmaker said in a statement viewed by Reuters ahead of a public announcement expected as soon as Wednesday. The vehicle would hit the market in around three years, and consumers would get a taste when the company unveils a concept car, dubbed the Qs Inspiration electric sedan, at the Shanghai auto show later this week, Nissan officials said. "China has the most growth potential for electric vehicles globally, especially in the premium segment," Infiniti Chairman Christian Meunier said in the statement seen by Reuters. Automakers operating in China have to sell more so-called new-energy vehicles, either battery electric cars or plug-in electric hybrids, to comply with official production quotas designed to reduce smog. It was not immediately clear whether Infiniti planned to produce its first electric vehicle in other markets. An Infiniti spokesman said, however, the brand did not intend to export the e-sedan from China. The planned e-sedan is part of Infiniti's longer-term strategy to significantly electrify its product lineup. Brand officials have said that from 2021 every Infiniti model launched will be either an all-electric car or so-called "e-Power" hybrids, underlining Nissan's previously announced plan to make Infiniti primarily an electrified offering. The sedan likely would be built on a new flexible architecture developed specifically to accommodate electrified powertrains, Infiniti said in the statement. Its design, especially the interior, would be significantly different than current models, design chief Karim Habib said. EVs do not have bulky gasoline engines and transmissions, opening up space inside the car. "It will have a flat floor, and if you are a passenger you can cross your legs or stretch out your legs," Habib told Reuters. Competition in China's rapidly emerging electric car market is heating up amid an onslaught of models from startups such as Nio and WM Motor, as well as those from established automakers. In the luxury segment, Infiniti will be competing with Tesla Model S and Model X, as well as other models due to be launched in coming months by Audi, Mercedes-Benz, BMW and Lexus.

Cadillac CT6 ushers in new naming convention

Johan de Nysschen has been at his new post as president of Cadillac for not even three months , but he's already seen two of his most notable accomplishments from his two-year tenure as president of Infiniti matched by Cadillac. The brand has announced that it is relocating its headquarters, and is now officially changing its nomenclature.
The brand's new flagship model will abandon the familiar three-letter designation enjoyed by every other model in the range (aside from the Escalade), and adopt an alpha-numeric title. So, rather than the expected title of LTS, Cadillac's top-end car will be called the CT6.
Of course, this won't be limited to just one model. According to Cadillac's press release, "familiar lettering like 'CT' would be used for car models, with the number indicating the relative size and position of the cars in the hierarchy of Cadillac models." And yes, that means what you think it means - Cadillac will use the exact same naming formula, albeit with different letters, as Infiniti.
