The tricky business of octane, power, and MPG

Given tepid green-car sales numbers this year, consumers in the US aren't making the transition away from internal combustion engines too quickly. Regulations are still mandating cleaner emissions, though. In addition to downsizing and turbocharging, there's growing consideration about moving to higher-octane fuel to improve overall efficiency. In a new report, engineers at FCA, Ford and General Motors Powertrain are showing that it could work, too. The major advantage to higher-octane fuel is that it supports higher compression ratios. That in turn can lead to more power from burning the same amount of gas. "Higher ethanol content is one available option for increasing the octane ratings of gasoline and would provide additional engine efficiency benefits for part and full load operation," the researchers write in the study's abstract. The authors even think it could be possible to update some modern vehicles' engine calibration to be optimized for the better gas. While the benefits are there, we still have a long way to go before higher-octane fuel becomes a national standard. According to Green Car Congress, 87 percent of the gas sold in the US is regular grade 87-octane. Meanwhile, premium 91-93 octane makes up just 10 percent. The various grades of fuel illuminate even more annoyances with the current system. For example, Ford generally recommends 93-octane for EcoBoost engines, and the power outputs that the company publishes are based on using it. However according to Green Car Reports, such premium gas is very difficult to find in some regions of the US, especially along the West Coast. The powertrains still run on lesser grades but with lower power output. The researchers' discussion of possibly increasing ethanol in gas also comes during a heated debate on the substance. The current administration is pushing for less of the corn-based fuel in the coming years. Although, several presidential hopefuls might be favor of reversing that course.

Recharge Wrap-Up: Tesla, CarCharging and the EPA

Credit Suisse analysts are bullish on Tesla. The group gives the electric car company's stock an "outperform" rating with a target price of $325. For its continued success, Credit Suisse cites the vehicles' superior technology, in turn offering more torque, roominess and reliability. Says analyst Dan Galves said of Tesla's competition with ICEs, "If Tesla can get to cost-parity with Internal Combustion vehicles and still offer $1,400 to $2,500 per year fuel savings to the consumer, it won't be a fair fight."

The Tesla app is adding this functionality soon, perhaps with the update to iOS 8. It's not yet clear how this function will work, but it's one more innovative convenience feature that Model S owners can enjoy. That means drivers will have less to carry in their pockets or purses when they go for a drive. Read more at 9 to 5 Mac. CarCharging Group has remotely lowered the amperage on some of its residential users' Blink charging stations to 24 amps. This will slow down the charging time for affected customers with 6.6-kilowatt charging by about 15 percent. The company cited safety reasons for the move, with concerns about overheating. The amperage reduction is temporary, until CarCharging is able to provide replacement parts for the chargers. Some are concerned about the delayed action, as well as the fact that the reduction was handled without owner permission. Read more at Plugin Cars. Ford is halting test drives and sales of certain C-Max hybrid and Focus models due to a safety concern. Cars made during a single week this month at a Michigan factory may not have enough ball bearings in the steering gear assembly, which could lead to loss of control. None of the affected cars have been sold, Ford says, and about 50 units are currently at dealerships. Just over 600 will need to be recalled. Dealerships have been notified of the problem.

The report shows a 66-percent reduction in benzene, almost 60 percent reduction in mercury from man-made sources, 84 percent less lead and more.

UAW warns automakers: Restarting U.S. plants is 'too soon and too risky'

WASHINGTON/WARREN, Mich. — The head of the United Auto Workers union on Thursday said it was "too soon and too risky" to reopen auto plants and Michigan's economy in early May, citing insufficient scientific data and coronavirus testing to assure workplaces are safe. The warning from UAW President Rory Gamble on Thursday afternoon came as General Motors Co , Ford Motor Co and Toyota Motor Corp took new steps toward reopening North American vehicle manufacturing operations in an environment where consumer demand is uncertain and worker safety paramount. The union has said that 24 of its members have died from Covid-19, though it was unclear whether they might have become infected in the workplace. Unionized Detroit automakers and non-union German and Asian automakers have been preparing to restart U.S. vehicle making operations by early May. Companies have shifted reopening dates amid uncertainty about government stay-at-home orders. Gamble's statement appeared to derail plans by the Detroit Three to start bringing UAW workers back to vehicle manufacturing jobs on May 4. The longer the automakers cannot produce profitable U.S.-made trucks and sport utility vehicles, the longer they burn cash. The UAW leader's statement was also aimed at Michigan Gov. Gretchen Whitmer, who has come under pressure from conservative groups and President Donald Trump to ease coronavirus stay-at-home restrictions. "At this point in time, the UAW does not believe the scientific data is conclusive that it is safe to have our members back in the workplace. We have not done enough testing to really understand the threat our members face," Gamble said. "We strongly suggest to our companies in all sectors that an early May date is too soon and too risky to our members, their families and their communities." Gamble said the union was "happy with the auto companiesÂ’ response and cooperation on working through the health and safety protocols we will need in the workplace when it is appropriate to restart." Earlier Thursday, GM began notifying front line managers to come back to work next week to get trained on new safety protocols designed to prevent the spread of the novel coronavirus as workers return to plants.
