A cool boost to turbocharger performance

Since the advent of the forced-induction engine, we have been looking for ways to get every drop of performance we can. There are many approaches to getting additional power using better intercooling, water injection, or even adding nitrous oxide. One take on a short instant burst of power is being researched by Mahle and involves providing supercooled air to an engine, which allows it to burn a leaner fuel mixture and produce more power. The supercooling idea is not new and was examined by Ford in 1993 on the Mustang Mach III concept car, then brought up again in 2003 with the SVT F-150 Lightning concept. Ford called its system the SuperCooler; it was designed to work with any turbocharged or supercharged engine equipped with a water-to-air intercooler. The system on the Lightning concept used a small tank of antifreeze that was hooked up to the truck air conditioning compressor. The air conditioning compressor cooled the antifreeze down to about 30 degrees. The other side of the tank was hooked up to the air-to-water intercooler, which usually had a temperature over 100 degrees. Once the antifreeze was circulated from the tank into the intercooler, it would lower the intercooler temperature and provide for a cooler, denser air charge into the engine; the result was around 50 extra horsepower for a burst of about 30 seconds to a minute, depending on the size of the tank. The system for the Lightning was to be offered as a $750 option and would have been targeted towards drag racers and the like, as it could be used for a run down the drag strip and then re-cooled by the time the truck was back in line. The system was fairly non-intrusive – it only weighed about 25 pounds and did not require a new compressor or intercooler. But as with many concepts, it was ultimately scrapped. The technology was always stuck in the back of my mind, but with larger and more powerful engines being produced it could not find its place. With the advent of new fuel economy standards, we have seen small-displacement turbocharged engines pop up and they seem like the perfect candidate for this type of technology. Ford's EcoBoost 1.0-liter three-cylinder turbocharged engine, as used in the Fiesta and Focus, is one such candidate for this technology. It would add a negligent amount of weight but could provide a boost of 10 to 20 horsepower when needed, like merging onto the highway or catching up to traffic.

Ford Explorer problems gutted third-quarter sales

In early September, the Detroit Free Press published a feature noting numerous problems Ford's having with the 2020 Explorer and 2020 Lincoln Aviator launches. Issues with both SUVs, built at Ford's Chicago Assembly Plant, were so rife and dire that the automaker was trucking the vehicles 275 miles away to Michigan for repairs. Bloomberg reported earlier this month that Explorer's third-quarter sales dropped 48 percent compared to the previous model in 2018, with dealers unable to get enough units on lots for customers. Nor is the snafu over: Automotive News reports that another "batch of about 2,500 Explorers in need of repairs" arrived recently in Michigan, and sales through the first nine months of 2019 are down 31 percent. Sales dips during model changeovers are to be expected as old inventory gets sold down and new production ramps up, but this is different. Ford U.S. sales boss Mark LaNeve told Bloomberg earlier this month, "We’ve got adequate inventory in our stores. For Q4, availability wonÂ’t be an issue. WeÂ’ll be able to hit our stride with Explorer starting now." It's hard to know whether that's true, with thousands of Explorers still piling into Michigan; the batch AN mentioned represents about 5 days of sales during an average month in 2018, before the drawdown and interruptions hampered matters. And when Consumer Reports tested the Ford Explorer it bought this summer, it titled the review, "2020 Ford Explorer drives nicely but has many flaws / Poor interior quality and a high price overshadow the SUV's improvements."   On top of that, the AN piece mentions a new impediment to uncorking the Explorer sales stream: Worker strife in the Chicago plant. Allegedly, "Roving groups of workers are intimidating other employees, creating a hostile environment, the people said. ThatÂ’s driving up turnover and leaving some vehicle assembly unfinished, contributing to the company having to complete the work at the Michigan factory or at dealerships, the people said." Ford's been fined twice before for the same kinds of issues at its plants, once in 1999, again in 2017, but a spokesperson said Ford isn't aware of any such problems now. The pressure otherwise has got to be unpleasant for everyone on the Explorer team, from CEO Jim Hackett down. The automaker was meant to be "turning the corner" in April, but as of now, shares are down, credit rating is down, earnings are down.

Ford F-450 claims best-in-class towing, company abandons practice of removing items to boost payload number

The ongoing heavy-duty truck battle between Ford and Ram is showing no signs of slowing down. The Blue Oval is trying to remove at least one point of contention between the two brands by testing its 2015 F-450 Super Duty using the Society of Automotive Engineers J2807 towing standard, which Ram also uses. In the new evaluation, the F-450 is rated at a max towing capacity of 31,200 pounds. That's an identical amount as under Ford's own, previous test.
"We leave no doubt with customers that the F-450 pickup truck has best-in-class towing of 31,200 pounds - whether tested using our own internal towing standards or SAE J2807," said Raj Nair, Ford group vice president for Global Product Development, in the company's release.
At the same time, Ford is also changing how it calculates the F-450's payload. Instead of using its minimum curb weight as before, the brand is now using the truck's base curb weight. The revision lowers the pickup's rating to 5,300 pounds, compared to 5,450 pounds previously. The company said in its announcement that the reason for this is "aligning its payload rating practices with other manufacturers to make it easier for customers to compare vehicles." General Motors made a similar switch for its pickups in August.
