Jay Leno is far beyond driven in his 1971 Pantera

Perhaps it's fitting that the band Pantera is known for its heavy metal music, because the DeTomaso Pantera is the automotive equivalent of a metal album. It's short, aggressive and makes a mean sound. It doesn't mess around either, with a Ford 351-cubic-inch (5.75-liter) V8 sending mountains of torque to the rear wheels. This week, Jay Leno takes us on a detailed tour of his '71 to show why it rocks.
There's a regular format to Jay Leno's Garage. It starts with Jay and maybe a guest taking a look at the car and talking about its history, and then they take it out on the open road. However, this video is practically a Pantera buyer's guide. Jay is adamant from the start that the last thing anyone should own is a stock example. To remedy this, he and his guest, the editor of the Pantera Club magazine, take viewers to school about some of the ways to turn them into even better performance machines.
No matter what you do to it, though, the Pantera requires that the driver adapt to it, not the other way around. For example, Jay isn't a big guy by most standards, but he has to cram himself into the cockpit with his shoes off and shirt partially unbuttoned just to go for a drive. Still, once out on the road, it all makes sense with that rumbling V8 and those Italian supercar looks. Scroll down to watch and learn a lot more about this uncompromising '70s performance car.

Ford recalls 650,000 trucks and SUVs for defective wipers

Ford announced earlier this month that it is recalling 652,996 F-Series pickups, Expeditions and Lincoln Navigators produced for the 2020 and 2021 model years to address an issue that may cause their windshield wipers to separate, reducing visibility and leading to potentially hazardous driving conditions.  According to the Blue Oval, one of its suppliers used worn tooling components that resulted in wiper arms being produced with splines that are not tall enough to fully engage the motor pivots they're mounted to, which can cause the connection to strip when the motors are turned on. This could result in the wiper arms not moving at all, or engaging only intermittently.  "Worn wiper arm spline tooling core inserts at the supplier resulted in insufficient spline tooth height, which can cause the arm attachment to strip when used with a certain wiper motors with higher torque," Ford said in its defect report to NHTSA. "Potential symptoms include erratic or slow wipe speed of the driver or passenger wiper arm. An improper functioning wiper arm may potentially result in reduced visibility in certain conditions, which could increase the risk of a crash." Ford says the vehicles were not produced in VIN order, so while not all of the nearly 653,000 vehicles have bad wiper arms, they're all suspect until proven safe. Ford will notify owners of the recall campaign starting in May.  Related video: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.

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.
