Tesla co-founder unveils electric garbage truck
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’s Raptor engine family has steadily increased sea-level thrust while simultaneously reducing mass, turning iterative engineering gains into substantially higher performance for the Super Heavy booster. CEO Elon Musk shed more light on how powerful Raptor 4 will be, and it’s pretty crazy.
Raptor 1 delivered 185 metric tons of thrust at roughly 2,080 kilograms, while Raptor 2 raised that to 230 tons while cutting mass to about 1,630 kilograms. SpaceX data for Raptor 3 lists a target of 280 tons at 1,525 kilograms (with further reductions in associated vehicle hardware), while operational flight ratings have been cited near 250 tons.
This morning, Elon Musk stated that Raptor 4 is expected to reach 300 tons of sea-level thrust at roughly the same mass as Raptor 3. Across these versions, thrust has risen by more than 60 percent from the first engines while engine mass has fallen, producing a sharp improvement in thrust-to-weight ratio. This is a true testament to how great SpaceX engineering has been:
🚀 Elon says Raptor 4 will make 300 tons of thrust at sea level at roughly the same mass as Raptor 3.
How far Raptor has come:
Raptor 1: 185 tf, 2,080 kg
Raptor 2: 230 tf, 1,630 kg
Raptor 3: 250 tf, 1,525 kg
Raptor 4: 300 tf33 on Super Heavy = ~9,900 tf, nearly 3x Saturn V https://t.co/HQDswZhyvL

With 33 engines on SuperHeavy, the jump from earlier versions to a 300-ton Raptor 4 would produce roughly 9,900 metric tons of total liftoff thrust, nearly three times the Saturn V’s approximately 3,400 metric tons from its five F-1 engines.
This is not just a larger number on a data sheet, either, as sea-level thrust is the force available the moment the vehicle leaves the pad. This is when it is heaviest and still deep in Earth’s gravity well and dense atmosphere.
Higher levels of sea-level thrust directly improves the initial thrust-to-weight ratio of the full stack. A higher ratio produces faster acceleration off the pad, which shortens the time the rocket has to spend fighting gravity, and gravity losses during the first minute or two of the flight are a major drain on total available delta-v. Every second shaved off of that early climb preserves more propellant energy for reaching orbital velocity or for carrying extra payload.
Because Super Heavy’s engine count is constrained by vehicle diameter and packing density, increasing thrust per engine is the most straightforward way to raise total liftoff performance without redesigning the booster structure or design.
The same-mass target for Raptor 4 is equally important. Holding engine mass roughly constant while raising thrust improves the engine’s own thrust-to-weight ratio and reduces the structural and propellant mass fraction that must be carried solely to support the engines.
Earlier Raptor iterations also simplified or eliminated extensive vehicle-side hardware such as heat shields. These gains compound: more force for less installed mass leaves additional capacity for propellant, payload, or operational margins such as engine-out capability.
For Starship’s architecture, the practical effects are large. Greater liftoff thrust supports heavier vehicles, larger propellant loads, and higher payloads to low Earth orbit, figures SpaceX has targeted in the 100-plus-ton reusable range. That capacity underpins orbital refueling, lunar missions, and eventual Mars cargo and crew flights.
Continued growth in sea-level thrust therefore tightens the gap between theoretical rocket performance and the high flight rates and reusability needed to make large-scale space transport practical.
Tesla has expanded its Tesla Assisted Driving (TAD) suite to its tenth European country, as Latvia joined a growing list of European Union member states authorizing the company’s advanced driver assistance technology.
Tesla Europe announced this morning that the system is now approved in Latvia, with a software rollout to begin soon.
The approval and rollout follow recognition of a provisional European type approval originally granted by the Netherlands’ RDW authority on April 10.
🚨 Latvia has just received approval for Tesla Full Self-Driving (Supervised)
This is the 10th country in the EU to gain approval:
1. Netherlands — 10 April 2026 (original RDW approval)
2. Lithuania — 20 May 2026
3. Estonia — 29 May 2026
4. Denmark — 9 June 2026
5. Belgium — 10 June 2026
6. Slovenia — 7 September 2026
7. Czechia — 21 September 2026
8. Croatia — 29 September 2026
9. Slovakia — 16 October 2026— TESLARATI (@Teslarati) October 26, 2026
Latvia’s Road Traffic Safety Directorate (CSDD) evaluated the Dutch documentation, coordinated with the other national authorities, and reviewed updates from Tesla. These included tightened limits on speed offsets, automatic resets of any manual speed adjustments after each trip, and stronger driver monitoring.
In Europe, the feature is marketed as Tesla Assisted Driving after a recent rule change that labeled the name “Full Self-Driving” as misleading.
The system remains an SAE Level 2 driver assistance tool, not unsupervised autonomy. It can control speed, steering, braking, lane changes, and intersections while following a navigation route. Drivers need not keep their hands on the wheel at all times, yet they must continuously monitor the road and be prepared to intervene immediately.
The sequence of EU recognitions began with the Netherlands in April and continued through Lithuania, Estonia, Denmark, Belgium, Slovenia, Czechia, Croatia, and Slovakia. Most have relied on mutual recognition of the single Dutch provisional approval rather than independent national testing.
These national clearances do not yet constitute bloc-wide authorization. An EU-wide decision requires a qualified majority in the Technical Committee on Motor Vehicles: at least 15 of 27 member states representing 65 percent of the EU population. Larger markets, like Germany, France, and Italy, remain under review, and a vote is expected this December.
However, for Latvian Tesla owners with compatible vehicles and software, the imminent rollout expands access to the supervised system while underscoring that attentive human oversight remains essential.
Tesla expanded its Robotaxi geofence in Houston, Texas, today, enlarging the service area and drawing a new rocket-shaped boundary across the city’s northwestern and central parts.
Although CEO Elon Musk said it was just a coincidence, the expansion seems to be an ode to SpaceX and its potential merger with Tesla.

It looks a lot like a rocket — we all remember the shape in Austin 🤣 https://t.co/cFOPEuiJ4u

The official Tesla Robotaxi account announced the change with the lines “Houston, we have liftoff” and “Bigger service area now live,” pairing them with a map overlay.
The prior white geofence, roughly 25 square miles covering Jersey Village, Harvest Bend, and the Willowbrook corridor along U.S. 290 and State Highway 249, now sits inside a larger blue zone that stretches southeast toward Bellair and closer to central Houston.
Houston’s Robotaxi service launched on April 18, 2026, the same day as Dallas, as Tesla’s first unsupervised public expansion beyond Austin. From the start, the vehicles were Model Ys running without anyone in the front seats, booked through the dedicated Tesla Robotaxi app and open to the public inside the geofence.
Trackers measured the initial zone at about 25 square miles; by late September it had not grown substantially. Community and registry data indicated a modest local fleet of unsupervised Model Ys, while dozens to nearly 200 Cybercabs, the purpose-built, steering-wheel-free two-seaters, have been spotted staging and testing in Houston lots, though public Cybercab rides remain limited to Austin for now.
Across the broader Robotaxi program, Tesla began public Robotaxi rides in Austin in June 2025, as a small geofence and vehicles with safety monitors became available for a ride-hailing service. Later on, Tesla removed the monitors and steadily expanded the service area until it covered most of the Austin metro area.
Unsupervised Robotaxi services now run in six cities: Austin, Dallas, Houston, Miami, Orlando, and Tampa. Cumulative driverless miles reported by the company have reached several million. The Cybercab entered public service in Austin in early September 2026 and has scaled rapidly there. The company has also said that Dallas is next for Cybercab rides in November, with further cities and 24/7 hours targeted by year-end, plus fleet-operator sales of the vehicle.
Waymo also operates a fully driverless service in Houston, which has been open to the public since August of this year.
The Houston expansion continues Tesla’s pattern of starting with tightly controlled validation zones before widening coverage as real-world data accumulates, while the rocket motif on the map underscores the company’s habit of injecting visual flair into its autonomy rollout.
Riders inside the new boundary can request unsupervised Model Y trips in the Robotaxi app; exact operating hours and further Cybercab availability remain subject to app updates and company statements.
