Tesla co-founder unveils electric garbage truck

Published

on

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.

Tesla already has a complete Robotaxi model, and it doesn’t depend on passenger count

That scenario was discussed during the company’s Q4 and FY 2025 earnings call, when executives explained why the majority of Robotaxi rides will only involve one or two people.

Tesla already has the pieces in place for a full Robotaxi service that works regardless of passenger count, even if the backbone of the program is a small autonomous two-seater. 

That scenario was discussed during the company’s Q4 and FY 2025 earnings call, when executives explained why the majority of Robotaxi rides will only involve one or two people.

Two-seat Cybercabs make perfect sense

During the Q&A portion of the call, Tesla Vice President of Vehicle Engineering Lars Moravy pointed out that more than 90% of vehicle miles traveled today involve two or fewer passengers. This, the executive noted, directly informed the design of the Cybercab. 

“Autonomy and Cybercab are going to change the global market size and mix quite significantly. I think that’s quite obvious. General transportation is going to be better served by autonomy as it will be safer and cheaper. Over 90% of vehicle miles traveled are with two or fewer passengers now. This is why we designed Cybercab that way,” Moravy said.

Elon Musk expanded on the point, emphasizing that there is no fallback for Tesla’s bet on the Cybercab’s autonomous design. He reiterated that the autonomous two seater’s production is expected to start in April and noted that, over time, Tesla expects to produce far more Cybercabs than all of its other vehicles combined.

“Just to add to what Lars said there. The point that Lars made, which is that 90% of miles driven are with one or two passengers or one or two occupants, essentially, is a very important one… So this is clearly, there’s no fallback mechanism here. It’s like this car either drives itself or it does not drive… We would expect over time to make far more CyberCabs than all of our other vehicles combined. Given that 90% of distance driven or distance being distance traveled exactly, no longer driving, is one or two people,” Musk said. 

Tesla’s robotaxi lineup is already here

The more interesting takeaway from the Q4 and FY 2025 earnings call is the fact that Tesla does not need the Cybercab to serve every possible passenger scenario, simply because the company already has a functional Robotaxi model that scales by vehicle type.

The Cybercab will handle the bulk of the Robotaxi network’s trips, but for groups that need three or four seats, the Model Y fills that role. For higher-end or larger-family use cases, the extended-wheelbase Model Y L could cover five or six occupants, provided that Elon Musk greenlights the vehicle for North America. And for even larger groups or commercial transport, Tesla has already unveiled the Robovan, which could seat over ten people.

Rather than forcing one vehicle to satisfy every use case, Tesla’s approach mirrors how transportation works today. Different vehicles will be used for different needs, while unifying everything under a single autonomous software and fleet platform.

Tesla Cybercab spotted with interesting charging solution, stimulating discussion

Tesla Cybercab units are being tested publicly on roads throughout various areas of the United States, and a recent sighting of the vehicle’s charging port has certainly stimulated some discussions throughout the community.

The Cybercab is geared toward being a fully-autonomous vehicle, void of a steering wheel or pedals, only operating with the use of the Full Self-Driving suite. Everything from the driving itself to the charging to the cleaning is intended to be operated autonomously.

But a recent sighting of the vehicle has incited some speculation as to whether the vehicle might have some manual features, which would make sense, but let’s take a look:

The port is located in the rear of the vehicle and features a manual door and latch for plug-in, and the video shows an employee connecting to a Tesla Supercharger.

Now, it is important to remember these are prototype vehicles, and not the final product. Additionally, Tesla has said it plans to introduce wireless induction charging in the future, but it is not currently available, so these units need to have some ability to charge.

However, there are some arguments for a charging system like this, especially as the operation of the Cybercab begins after production starts, which is scheduled for April.

Wireless for Operation, Wired for Downtime

It seems ideal to use induction charging when the Cybercab is in operation. As it is for most Tesla owners taking roadtrips, Supercharging stops are only a few minutes long for the most part.

The Cybercab would benefit from more frequent Supercharging stops in between rides while it is operating a ride-sharing program.

Tesla wireless charging patent revealed ahead of Robotaxi unveiling event

However, when the vehicle rolls back to its hub for cleaning and maintenance, standard charging, where it is plugged into a charger of some kind, seems more ideal.

In the 45-minutes that the car is being cleaned and is having maintenance, it could be fully charged and ready for another full shift of rides, grabbing a few miles of range with induction charging when it’s out and about.

Induction Charging Challenges

Induction charging is still something that presents many challenges for companies that use it for anything, including things as trivial as charging cell phones.

While it is convenient, a lot of the charge is lost during heat transfer, which is something that is common with wireless charging solutions. Even in Teslas, the wireless charging mat present in its vehicles has been a common complaint among owners, so much so that the company recently included a feature to turn them off.

Production Timing and Potential Challenges

With Tesla planning to begin Cybercab production in April, the real challenge with the induction charging is whether the company can develop an effective wireless apparatus in that short time frame.

It has been in development for several years, but solving the issue with heat and energy loss is something that is not an easy task.

In the short-term, Tesla could utilize this port for normal Supercharging operation on the Cybercab. Eventually, it could be phased out as induction charging proves to be a more effective and convenient option.

Tesla has confirmed that it is now producing both the anode and cathode of its 4680 battery cells using a dry-electrode process, marking a key breakthrough in a technology the company has been working to industrialize for years. 

The update, disclosed in Tesla’s Q4 and FY 2025 update letter, suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.

Dry cathode 4680 cells

In its Q4 and FY 2025 update letter, Tesla stated that it is now producing 4680 cells whose anode and cathode were produced during the dry electrode process. The confirmation addresses long-standing questions around whether Tesla could bring its dry cathode process into sustained production.

The disclosure was highlighted on X by Bonne Eggleston, Tesla’s Vice President of 4680 batteries, who wrote that “both electrodes use our dry process.”

Tesla first introduced the dry-electrode concept during its Battery Day presentation in 2020, pitching it as a way to simplify production, reduce factory footprint, lower costs, and improve energy density. While Tesla has been producing 4680 cells for some time, the company had previously relied on more conventional approaches for parts of the process, leading to questions about whether a full dry-electrode process could even be achieved.

4680 packs for Model Y

Tesla also revealed in its Q4 and FY 2025 Update Letter that it has begun producing battery packs for certain Model Y vehicles using its in-house 4680 cells. As per Tesla: 

“We have begun to produce battery packs for certain Model Ys with our 4680 cells, unlocking an additional vector of supply to help navigate increasingly complex supply chain challenges caused by trade barriers and tariff risks.”

The timing is notable. With Tesla preparing to wind down Model S and Model X production, the Model Y and Model 3 are expected to account for an even larger share of the company’s vehicle output. Ensuring that the Model Y can be equipped with domestically produced 4680 battery packs gives Tesla greater flexibility to maintain production volumes in the United States, even as global battery supply chains face increasing complexity.
