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 QX80 to spearhead new direction for Nissan's luxury brand

Infiniti has had a tumultuous time in the last few years. However, a new plan is under way to revive Nissan's luxury marque, and to give it some much-needed direction. Now, Infiniti chairman Peyman Kargar has detailed his plans for the first time, and revealed that the QX80 will be at the vanguard of this new push. Left to languish under former Nissan CEO Carlos Ghosn's quest for market share at the cost of all else, Infiniti's lineup failed to receive the necessary updates in several hotly contested segments. In a time when the luxury brands have seen record profits, Infiniti has instead seen its sales plummet. In 2018 the brand was among the first to announce a date by which it would "go electric." That was taken by many to mean solely electric or hybrid vehicles after 2021, but that time has come and gone. Infiniti missed its own deadline for a first EV model last year, and sales have nosedived by more than 50 percent since 2019 (117,708 in U.S. sales in 2019, versus 58,553 in 2021). Part of that is due to the  pandemic and resulting semiconductor shortage that's plagued the entire industry, but there's no doubt that the brand is seldom uttered in the same breath as Mercedes, BMW, Lexus or Audi. Speaking with Automotive News, Kargar outlined a three-phase plan to get Infiniti back on its feet. The first phase, focusing on restructuring and recovery, was just completed in March. Infiniti has now turned record profits globally, Kargar said.  Phase two has now begun and will play out through March 2026. By this time next year, designers will have locked in a new corporate face to take over on all new models. Leading the charge with that identity will be a new QX80 that arrives in late 2023 or early 2024.  Kargar didn't disclose details, but called it the future flagship of the marque. It will have enhanced performance specs to distance itself from the Nissan Armada on which it is based. Infiniti hopes that the QX will be seen as a competitor against the likes of the Cadillac Escalade Lexus LX, and Range Rover. Despite riding on the same platform as the Patrol — a Land Cruiser-like body-on-frame SUV — since 2010, the QX has not fallen in sales as much as other models. Part of the rebranding also includes a unification of Infiniti's identity. Kargar spoke of a new dealership look and feel, which includes a "brand scent" for showrooms and a "sound signature" that will tie in apps, websites, and call centers.

Major automakers post mixed US June sales figures

General Motors, Ford and Fiat Chrysler Automobiles NV posted declines in US new vehicle sales for June on Monday, while major Japanese automakers reported stronger figures. Once again, demand for pickup trucks and crossovers offset a decline in sedan sales. Automakers' shares rose as overall industry sales still came in above Wall Street expectations. The US auto industry is bracing for a downturn after hitting a record 17.55 million new vehicles sold in 2016. Analysts had predicted that overall, US vehicle sales would fall in June for the fourth consecutive month. As the market has shown signs of cooling, automakers have hiked discounts and loosened lending terms. Car shopping website Edmunds said on Monday the average length of a car loan reached an all-time high of 69.3 months in June. "It's financially risky, leaving borrowers exposed to being upside down on their vehicles for a large chunk of their loans," said Jessica Caldwell, Edmunds' executive director of industry analysis. GM said its sales fell about 5 percent versus June 2016, but that the industry would see stronger sales in the second half of 2017 versus the first half. "Under the current economic conditions, we anticipate US retail vehicle sales will remain strong for the foreseeable future." GM shares were up 2.4 percent in morning trading, while Ford rose 3.3 percent and FCA shares jumped 6 percent. "US total sales are moderating due to an industry-wide pullback in daily rental sales, but key US economic fundamentals clearly remain positive," said GM chief economist Mustafa Mohatarem. "Under the current economic conditions, we anticipate US retail vehicle sales will remain strong for the foreseeable future." Ford said its sales for June were hit by lower fleet sales to rental agencies, businesses, and government entities, which fell 13.9 percent, while sales to consumers were flat. But it sold a record 406,464 SUVs in the first half of the year, with Explorer sales increasing 23 percent in June. And sales of the F-150 had their strongest June since 2001. On a media call, Ford executives said an initial read of automakers' sales figures indicated a seasonally adjusted annualized rate of around 17 million new vehicles for the month, which would be better than 16.6 million units analysts had predicted. FCA said June sales decreased 7 percent versus the same month a year earlier.
