Ford’s 1.25-million-pound F-150 EV demo was easier than it looked, explains engineer

Last week, Ford made headlines when it released a video of its upcoming F-150 electric pickup truck pulling what could only be described as an unreal amount of weight. In the demonstration, the upcoming vehicle pulled ten double-decker rail cars, both empty and loaded with 42 gas-burning F-150s. The weight of the rail cars with the pickups in them was a whopping 1.25 million pounds, but the F-150 EV was able to pull everything without any issue. 

The demonstration was incredibly impressive, instantly eclipsing the feats of strength from other notable vehicles like the Tesla Model X, which pulled a Boeing 787 Dreamliner, and the Toyota Tundra, which towed a Space Shuttle. According to auto enthusiast and mechanical engineer Jason Fenske of YouTube’s Engineering Explained channel, though, Ford’s demonstration is actually far easier than it looked. 

Fenske notes that both the 787 Dreamliner and Space Shuttle pulled by the Model X and Tundra rode on rubber tires. On the other hand, the rail cars pulled by the electric Ford F-150 rested on steel wheels riding on steel railroad tracks. This, the engineer explains, makes a notable difference, particularly with regards to the coefficient of rolling resistance (the ratio of the force required to pull a rotational mass).

“Steel does not deform much at all, which is why railroads use steel wheels on steel tracks. This adds up to an extremely low coefficient of rolling resistance—about 0.0015. To pull a 10,000-pound train across a level surface, you only need a 15-pound force. For a truck to move a 1.25-million-pound train, it only requires about 1,875 pounds of force,” Fenske wrote. 

The engineer adds that generally, the maximum force a 4WD truck can generate will be equivalent to its weight, mostly due to the grip of its tires. Since the electric Ford F-150 prototype used in the demonstration was most certainly over 1,875 pounds, it would really have no issues pulling the 1.25-million-pound load. Had the F-150 EV attempted such a feat with a load equipped with pneumatic tires on pavement, the demonstration would most definitely have resulted in a much different outcome. 

Fenske’s points were outlined in an article on Road & Track, which delved more into the math behind Ford’s demonstration. A Ford spokesperson has responded to Fenske’s arguments, pointing out that the engineer’s calculations did not evaluate acceleration. The engineer wrote that he is currently waiting for Ford to provide more information about the demo, in order to calculate exactly how much power the demonstration took.

While the F-150 EV’s feat of strength could be explained by the automaker’s choice of cargo, the demonstration remains pretty impressive nonetheless. It does, if any, raise interest in the upcoming vehicle. Unfortunately, Ford Chief Product Development Officer Hau Thai-Tang noted during an interview with Yahoo Finance’s The First Trade that the all-electric version of the F-150 is still “a couple of years out,” though a hybrid version will be released in 2020.

Tesla Roadster event gets delayed due to unfavorable weather

Published

Tesla is delaying its event for the Roadster, moving it from this Thursday, October 1, to Thursday, October 15, due to unfavorable weather.

The company has said it has been tracking the weather for this Thursday closely with local meteorologists, and because the event can only be held outside, Tesla is making the call to delay it:

“We’ve been tracking the weather closely with local meteorologists, but given the severe conditions predicted & because this event can only be held outdoors, we’ve made the difficult decision to reschedule. New date is October 15. Additional details to follow.”

We are sure that this is bringing back PTSD for some Tesla fans, and we know it is not ideal, but this also reveals some things about the event. Tesla said that this can only be held outdoors, meaning it bodes well for the rumors that the vehicle could potentially hover.

Some believe that this was essentially confirmed by the FAA airspace restriction they were granted, but this could have been for a drone show or to keep drones from spying on the event.

Tesla Roadster is available for order once again following brief hold

The Roadster event has been long-awaited, and it is unfortunate that the weather is going to keep us all waiting a little bit longer.

The Tesla Roadster will be unveiled in Waco, Texas.

SpaceX turned a heralding moment for Starship into its greatest

Starship reached orbit despite losing an engine, deployed 26 Starlink V3 satellites on Flight 14.

SpaceX’s Starship reached orbit for the first time on Monday, and for a few nail-biting minutes it looked like it wouldn’t. During ascent on Flight 14, one of Ship 41’s six Raptor engines shut down early, and SpaceX’s livestream host Dan Huot told viewers the team had decided not to commit to orbit. Minutes later, after what Huot described as a lot of conversation in the control room, the final poll came back in favor, and a roughly 19 second burn of a single Raptor pushed the ship into orbit about 170 miles up.

The reversal matters because SpaceX had written the exit ramp into the mission plan. The company said it would only fire the orbital insertion burn if flight controllers confirmed enough backup hardware remained for the deorbit burn, a condition Teslarati laid out ahead of the flight. Losing an engine was exactly the scenario that rule was built for.

Pressing forward fits Elon Musk’s history. Falcon 1 failed three straight times before its fourth launch reached orbit in 2008, with SpaceX nearly out of money, and Starship was developed by flying prototypes until they broke. What changed this year SpaceX going public, and with $SPCX sliding below its IPO price in July when Flight 13 slipped, the short interest climbed significantly, as Teslarati reported at the time. A Starship potentially lost today with revenue generating next-gen Starlink satellites aboard would have landed directly on shareholders.

That pressure showed up after orbit. SpaceX cut a flight planned to last nearly 10 hours to about three, moving splashdown from west of Chile to the North Pacific near Hawaii. SpaceX gave no reason, though Musk said this month the company was being extremely cautious about debris risk. The single Raptor for deorbit worked, and Ship 41 completed its flip and landing burn before breaking apart in the water, an outcome SpaceX expected. Musk has structured SpaceX’s governance to shield long term bets from market pressure.

The payload is the bigger business story. Musk posted that all 26 Starlink V3 satellites deployed and are “operating nominally.” Each V3 is rated for about 1 Tbps of downlink and 160 Gbps of uplink, so this single launch adds roughly 26 Tbps, about 10 times what a Falcon 9 load of V2 Mini satellites adds. The V3 is too large for Falcon 9, making Starship the only vehicle that can build out the planned 100,000 satellite constellation, at up to 60 per flight once it reaches routine service. Unlike the 20 V3 units on Flight 13, which reentered on a suborbital path, these will raise their orbits and could begin serving customers within weeks and bring in hundreds of millions of additional dollars in projected Starlink revenue.

SpaceX has already begun winding down Falcon 9 Starlink launches from Florida in favor of Starship. Reported targets put Flight 15 as early as October 19, leaving about three weeks to diagnose Monday’s engine shutdown before the next orbital attempt.

Tesla Cybercab fleet doubles to well over 100 units

Tesla quietly doubled the size of its Cybercab fleet within the Robotaxi program in Austin, Texas, over the weekend to well over 100 units.

The move not only establishes more of the steering-wheel-less and pedal-less vehicles within the ride-sharing fleet Tesla has been operating for a year, but it also solidifies a more robust Robotaxi fleet as a whole.

Riders started receiving notifications from the Robotaxi app that stated: “Cybercab fleet has doubled: more rides available.”

Tesla first launched rides in the Cybercab in early September, although the Robotaxi fleet has been active for over a year, as rides began last Summer. Cybercab is truly Tesla’s most crucial vehicle release yet, as it is the first car any company has built that is geared toward full-fledged and end-to-end autonomy, never needing human intervention for anything.

Only available in Austin at the current time, Cybercab has two seats and has been spotted testing around various U.S. states and regions; Tesla plans to deploy the Cybercab in various U.S. cities in the coming months as a best-case scenario.

Tesla Cybercab gets initial tie-in to localized, in-house cathode plant

The availability of the Cybercab has doubled from just 58 units last Monday to 125 the following Friday. Marking a substantial increase in Cybercab availability, the additional ride-sharing units are more than welcome, as wait times for Cybercabs, especially, were quite high.

The dramatic increase is a sign that demand for Robotaxi is growing and Tesla is feeling more confident that its driverless ride-hailing suite, especially its Full Self-Driving software, is able to handle any traffic situation without explicit direction or supervision from a human being.
