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.

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.

2024 Infiniti QX80 gets Dark Chrome Appearance package, higher price

The body-on-frame Infiniti QX80 is entering the 2024 model year with a new appearance package offered on the most expensive trim level. It's otherwise unchanged compared to the 2023 model, which received Amazon Alexa compatibility, but every trim becomes more expensive. While the QX80's overall design doesn't change, the range-topping Sensory trim level gets an optional Dark Chrome Appearance package that includes black-painted door mirror caps as well as Dark Chrome trim on the front end, the fenders, and the hatch. The bundle gives the SUV a more subtle look, as models not equipped with the Dark Chrome Appearance package ship with flashier bright exterior trim pieces. The list of standard features includes a 12.3-inch touchscreen plus Apple CarPlay, Android Auto, and Amazon Alexa compatibility. Driving aids? It's got them: a surround-view camera, forward emergency braking with pedestrian detection, and back-up collision intervention come standard. The QX80 isn't the newest or best-selling model in its segment, but it's not as outdated as the age of its platform suggests. Infiniti positions the QX80 as its most expensive model, and it's increasing pricing across the board for 2024. Pricing is as follows: QX80 Luxe rear-wheel-drive: $76,045 ($1,650 more than in 2023) QX80 Luxe four-wheel-drive: $79,195 ($1,700 more than in 2023) QX80 Premium Select rear-wheel-drive: $80,680 ($1,685 more than in 2023) QX80 Premium Select four-wheel-drive: $83,780 ($1,685 more than in 2023) QX80 Sensory rear-wheel-drive: $87,730 ($1,685 more than in 2023) QX80 Sensory four-wheel-drive: $90,830 ($1,685 more than in 2023) Note that these figures include an $1,895 destination charge. The brand collected a $1,395 destination charge in 2023. Infiniti hasn't made any mechanical changes to the QX80. Power comes from a tried-and-true 5.6-liter V8 rated at 400 horsepower and 413 pound-feet of torque. It's bolted to a seven-speed automatic transmission, and it gives the big SUV a towing capacity of up to 8,500 pounds. Dealers across the nation will begin receiving the 2024 QX80 in the coming weeks. Infiniti hasn't commented on what's next for the model, but weaving together various tidbits of information released earlier in 2023 nudges us in the right direction.
