GM says it favors fuel-efficiency rules based on historic rates

WASHINGTON — General Motors backs an annual increase in fuel-efficiency standards based on "historic rates" rather than tough Obama era rules or a Trump administration proposal that would freeze requirements, according to a federal filing made public on Monday. The largest U.S. automaker said the Obama rules that aimed to hike fleet fuel efficiency to more than 50 miles per gallon by 2025 are "not technologically feasible or economically practicable." The Detroit automaker said that since 1980, the motor vehicle fleet has improved fuel efficiency at an average rate of 1 percent a year. Fiat Chrysler Automobiles NV said in separate comments that the auto industry is complying with existing fuel efficiency requirements by using credits from prior model years. As a result, even if requirements are frozen at 2020 levels, "the industry would need to continue to improve fuel economy" as credits expire, it added, warning if the government hikes standards beyond 2020 requirements "the situation worsens ... without some significant form of offset or flexibility." Fiat Chrysler and Ford urged the government to reclassify two-wheel drive SUVs as light trucks, which face less stringent requirements than cars. A four-wheel drive version of the same SUV is considered a light truck. Ford backs fuel rules "that increase year-over-year with additional flexibility to help us provide more affordable options for our customers." GM's comments said it was "troubled" that President Donald Trump's administration wants to phase out incentives for electric vehicles. The Trump plan's preferred alternative freezes standards at 2020 levels through 2026 and hikes U.S. oil consumption by about 500,000 barrels per day in the 2030s but reduces automakers' collective regulatory costs by more than $300 billion. It would bar California from requiring automakers to sell a rising number of electric vehicles or setting state emissions rules. The administration of former President Obama had adopted rules, effective in 2021, calling for an annual increase of 4.4 percent in fuel-efficiency requirements from 2022 through 2025. GM has been lobbying Congress to lift the existing cap on electric vehicles eligible for a $7,500 tax credit. The credit phases out over a 12-month period after an individual automaker hits 200,000 electric vehicles sold, and GM is close to that point.

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 Mustang Shelby GT500 has a bit of a dyno issue

We're of the mind that each and every dyno should come with Murphy's Law painted in big, visible letters down the side. For every ten successful dyno runs out there, it seems there's one where events to horribly wrong. Take, for example, the video below. The clip shows what happens when a Ford Shelby GT500 and a mobile dyno have a bit of a disagreement at the Performance Expo 24 in Sherbrooke, Quebec. We won't spoil the results for you, but we will say there's some substantial carnage involved.
It's unclear just how much damage ensues from the dust up or whether anyone was harmed in the incident, but from the looks of things, everyone made it out without serious injury. If only we could say the same for the machines involved. Check out the video below.
