Tesla co-founder unveils electric garbage truck

Published

The global transition from combustion engine to all-electric vehicle continues to move into new sectors as Wrightspeed has just released its first fleet of range-extended electric refuse trucks. The powertrain represents a new era in vehicle propulsion, repowering a generation of lighter, quieter, and more efficient vehicle fleets for urban streets.

Wrightspeed’s commercial application of the range-extended, turbine-electric powertrain is the heavy-duty Class 8 Freightliner, which will be delivered to The Ratto Group, a Sonoma County solid waste collection and recycling business. The Class 8 Freightliner is the first of at least fifteen electric vehicles that will be integrated into the trash company’s fleet over the next year, according to Tim Dummer, Wrightspeed’s chief business officer. Dummer, an engineering and commercialization executive, was brought into Wrightspeed in October, 2016 as part of the company’s ramp-up of its Range-extended Electric Vehicle (REV) powertrain systems.

Called The Route™, Wrightspeed’s REV powertrain is optimized for the refuse industry and can be customized to fit a variety of today’s heavy-duty truck platforms, replacing both the engine and the transmission. Much of the growing demand for the award-winning The Route is due to Wrightspeed’s founder, Ian Wright, one of the original co-founders of Tesla Motors. After his departure from Tesla Motors in 2003, Wright had a vision that electric vehicles could deliver high-performance without compromising intrinsic efficiency. Using turbines and applying electric vehicle principles to urban, heavy-duty trucks, The Route powertrain was the result.

The Wrightspeed system can power a 66,000-pound GVW truck, delivering up to 24 miles on battery power before the range extender kicks in. After that, range is nearly unlimited as long as there is fuel for the turbine. With fuel efficiency the equivalent of up to 7 mpg in combined electricity-liquid fuel operation, the powertrain can slash annual fuel consumption by 70 percent or more compared with the average diesel refuse truck. CEO Lou Ratto says he expects a fuel savings of at least 50 percent.

Eventually, all of Ratto’s 130 residential trash and recycling trucks may be retrofitted with the turbine-electric powertrain. This is an ambitious undertaking, as a refuse truck’s demanding duty cycle drains an electric powertrain’s batteries quickly.  Think start, then stop.  Start, stop. Wrightspeed’s electric powertrain drives more low-end torque to the wheels than conventional diesel engines, with less fuel, emissions, and noise.

Wrightspeed, in a sense, is recycling Ratto’s trash collection trucks. The Wrightspeed/ Ratto contract is thought to be in the range of $3 million to $5 million.

A new refuse truck that meets all California air quality standards costs more than $500,000, so Wrightspeed’s retrofit of Ratto’s existing trucks makes the system more cost-effective, Van Amburg relates. Sonoma County officials like the trash fleet electrification program because they see it as a means of improving local air quality, says Efren Carrillo, chairman of the Sonoma County Board of Supervisors. Ratto concurs. “Here in Sonoma County there is a lot of environmental consciousness, and we are always looking for ways to be cleaner, environmentally friendly, and help the bottom line. And the idea that [by electrifying the trucks] we can do this and get off the air quality rollercoaster and stop battling to meet California emissions requirements— that makes it all worthwhile.”

Wrightspeed featured its powertrain technology alongside Mack Trucks at Waste Expo 2016 in Las Vegas and signed a $30+ million agreement with NZ Bus, symbolizing multinational and multimodal demand for Wrightspeed’s powertrain technology. In June, the company was named a Technology Pioneer by the World Economic Forum (WEF), and CEO Wright was an invited presenter to the International Business Council of the World Economic Forum. He will be a keynote speaker at the upcoming SAE 2016 Range Extenders for Electric Vehicles Symposium in Knoxville, 2-3 November, 2016.

SpaceX turned a heralding moment for Starship into its greatest moment

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

Published

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.

Tesla has a ‘no human contact’ approach for Semi production

Published

on

Tesla is advancing a fully automated pipeline for the 4680 battery cells used in its all-electric Semi, spanning production from Giga Texas through shipment and direct consumption on the line at the new dedicated Semi Factory in Sparks, Nevada.

The approach was outlined by Tesla at its September 24 Semi Handover event, which launched high-volume production at its new 1.8-million-square-foot plant in Nevada, which sits adjacent to Gigafactory Nevada and is designed for an annual production rate of 50,000 trucks per year.

After years of pilot builds and what was a four-year-long redesign of the truck, Tesla moved the Semi from 2170 batteries to its in-house 4680 cells, which are made in Austin. The change cuts battery mass and total energy while holding range, a key step in making volume production a realistic possibility.

Cells will leave Giga Texas in trailers, and at the Nevada Semi plant, Tesla intends for a dedicated line to unload those trailers automatically, station the cells, and feed them straight into pack and vehicle assembly.

Both Lars Moravy, Tesla’s VP of Vehicle Engineering, and Dan Priestley, the Head of Tesla’s Semi program, described the goal as a “zero human touch point” from the moment the trailer arrives in Texas until a finished Semi drives off the production line in Nevada.

The unloading system that Moravy and Priestley described is just one piece of a much broader automation push. The plant uses what Tesla calls the highest-capacity electric monorail conveyance in vehicle manufacturing, carrying frames-in-white simultaneously. Powder-coating replaces conventional paint, and many processes that would normally require operators have been designed out.

Tesla has repeatedly said that “the best part is no part,” and the cell-handling plan extends that philosophy from the cell factory floor in Texas all the way to final assembly in Nevada.

If executed as described, the closed-loop flow would reduce labor, handling damage, and inventory buffers while tightening quality control on a component that represents a large share of the truck’s cost and weight. It also shortens the physical and organizational distance between two factories separated by more than 1,200 miles. The Semi itself now shares a bar-wound stator and other components with the Cybertruck, further linking Tesla’s passenger and commercial production systems.

High-volume output is expected to ramp gradually after the first trucks left the new line in April 2026. Early customers include PepsiCo, DHL, and U.S. Foods. Whether the automated trailer-to-line process reaches the promised zero-touch standard will be visible in the coming months as production scales. For Tesla, the Semi factory is another test of how far it can push “the machine that builds the machine” across sites.
