Ford recalls 125,000 Maverick, Escape, Corsair hybrids over fire risk

Ford is recalling more than 125,000 Maverick, Escape and Lincoln Corsair hybrids produced for the 2020-2023 model years to address a fire risk associated with failure of their internal combustion engines, which Ford says is happening with undue frequency. In the event of an engine block breach, oil and fuel vapors may collect under hood in places that would make them prone to ignition, meaning that an engine failure can do more than leave owners stranded.  "Isolated engine manufacturing issues have resulted in 2.5L HEV/PHEV engine failures involving engine block or oil pan breach," Ford said in its defect report to NHTSA. "In the event of an engine block or oil pan breach, the HEV/PHEV system continues to propel the vehicle allowing the customer to continue to drive the vehicle. As the customer continues to drive after a block breach, oil and/or fuel vapor continues to be expelled and accumulates near ignition sources, primarily expected to be the exhaust system." Per Ford, the "manufacturing issues" include poor machining of the engine crankshaft and contamination of engine block mating surfaces during assembly. The issue has been fixed in production, but 2.5-liter engines that escaped the factory with defects could be ticking time bombs. Ford's solution is to re-work the underhood components that allow combustible liquids and vapors near ignition sources. This way, the cars are better protected against immolation regardless of the circumstances. Signs of failure will be obvious, Ford says. Loud clanging or booming noises, a loss of power and smoke are all immediate signs that the customer should exit the roadway as safely and quickly as possible and shut the car down.  Owners should expect to receive notifications by the end of June or early July. They should begin circulating by mid-month. All remediation will be handled for the customer free of charge by their Ford dealerships.  Related video: This content is hosted by a third party.

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.
