Cummins has its eye on hybrid powertrains to help decarbonize the transport, construction, and mining spaces the operates in. To that end, the company has acquired the hybrid equipment experts First Mode, and plans to make the first commercially available retrofit hybrid system for mining equipment a reality not just soon – but now.

The Cummins brand is almost synonymous with diesel in the US, but they’re making big moves in the ZEV space, too, with their Accelera brand and, now, with their purchase of First Mode.

The acquisition includes the rights to all of First Mode’s tech in the mining and rail space, where the company has developed a full IP portfolio of “energy agnostic” (my words) electric drive powertrains that can draw power from internal combustion engines, hydrogen fuel cells, or batteries. And, because the First Mode Hybrid Electric Vehicle (HEV) retrofit is designed as a modular platform, it allows equipment fleets to either back out of the electric drive conversion or take them a step further, going to fully battery electric operation with same (relative) ease.

That sort of flexibility will help Cummins meet customers where they’re at – whether they’re OEMs, or fleet managers at multibillion-dollar mining operations.

“This acquisition is an important step forward in our goal to lead our Power Systems customers through the energy transition,” explains Jenny Bush, President of Power Systems at Cummins. “With First Mode’s hybrid retrofit technology, we are accelerating our ability to provide decarbonization solutions that meet miners’ need to drive down operating costs today.”

If the notion of converting heavy equipment from diesel to electric sounds familiar, that means you’ve been paying attention. The heavy mining equipment experts at Liebherr recently converted a pair of their massive R 9400 excavators from diesel to battery electric power for use at a Fortescue mine.

That project was successful enough to move millions of tons of Earth in just a few months – leading to a $4 billion order from the global mining leader for even more electric equipment.

“The modular design of Liebherr equipment makes it possible to repower existing diesel excavators to new zero emission configurations, such as electric powertrains,” explains Oliver Weiss, Executive Vice President of R&D, Engineering, and Manufacturing for Liebherr Mining. “This means that the diesel equipment customers buy today is also future-proofed for many years to come. The fact that we can ease the transition from traditional to decarbonized mining fleets for our customers is one of the key strategies of the Liebherr Zero Emission Mining Program.”

For their part, Cummins’ executives seem just as excited by the promise of offering electrified mining equipment that can utilize existing assets, dramatically extending their life while reducing the up-front costs usually associated with electrification.

“Cummins’ dedication to partnering with original equipment manufacturers (OEMs) and miners ensures that these technologies are developed and tested in real-world environments,” Jenny Bush adds. “With hybrid retrofit kits, modular component upgrades and scalable solutions, we are bringing miners the flexibility and confidence they need to decarbonize operations while adapting to evolving technologies and infrastructure.”

Cummins believes its trusted relationships with OEMs across various industries combined with their vast global service and parts network will give their hybrid retrofit packages a competitive edge, delivering technical support that similar, startup outfits simply can’t.

Tesla officially starts autonomous ‘testing’ phase in Austin days before planned launch

Tesla officially starts autonomous 'testing' phase in Austin days before planned launch

Tesla has officially entered the autonomous vehicle ‘testing’ phase in Austin, Texas days before its planned launch of a commercial service.

For months, Tesla has been discussing the launch of a self-driving ride-hailing fleet in June in Austin, Texas.

As we previously reported, the move is a major shift from Tesla’s long promise to enable unsupervised self-driving capabilities in millions of vehicles sold since 2016.

Instead, Tesla now plans to operate its own small internal fleet of vehicles with dedicated software optimized for a geo-fenced area of Austin and supported by “plenty of teleoperation.”

Tesla CEO Elon Musk has been talking about launching the paid ride-hailing service to customers in June, but there have been doubts. Musk admitted that Tesla only started testing the system without safety drivers at the end of May.

In comparison, Waymo tested its system, which was already in operation driverless in other cities, for 6 months with safety drivers and 6 months without safety drivers before launching its service in Austin earlier this year.

Tesla was also never on the list of ‘Known AV Operators in Austin‘ on the city’s official website.

As of today, it is now the case. Tesla has been added to the list in the “testing phase”:

Waymo is still the only company listed as being in the “deployment” phase.

It’s unclear if the website is lagging behind the test programs or if Tesla has only now officially started its self-driving testing in the city.

In the past, Tesla has managed to get around self-driving test reporting by claiming that its system is a level ADAS system and not actual “self-driving” – leaving the person in the driver’s seat responsible for the vehicle at all times.

Tesla vehicles with drivers in the driver’s seat and manufacturer plates have been spotted driving around Austin for the past few months.

It was recently reported that Tesla was aiming to launch its commercial autonomous ride-hailing service in Austin on June 12, but it was still a moving target.

Without achieving the deployment phase, Tesla is not going to be able to accept paid rides from customers like Waymo.

Musk has committed several times to launching the service by the end of June.

Electrek’s Take

Again, I’m hoping that Tesla has managed to improve FSD for the geo-fenced location significantly and that it will limit the speed, as the current public version of FSD barely achieves 500 miles between critical disengagements.

Removing the driver could result in some serious accidents.

Teleoperation will also help, but any kind of delay could also be dangerous. It is worrisome.

E-quipment highlight: Oshkosh Striker Volterra Aircraft Rescue and Fire Fighter

The Oshkosh-built Striker Volterra electric ARFF vehicle (Aircraft Rescue and Fire Fighter) packs advanced battery technology and multiple power options to deliver consistent emergency response performance no matter how long it needs to be in action.

Oshkosh has been manufacturing ARFF vehicles since it first launched the MB-5 for use by the US Navy back in 1968, and they’ve been pushing the envelope of disaster response performance ever since. The company’s latest ARFF, the electric-drive Striker Volterra shown here, features a slanted body with front bumper designed for maneuvering through the ditches and rough terrain they might encounter on a damaged runway. It’s also big — but it’s big for a purpose. Because ARFF vehicles don’t have to navigate the confines of city streets, they can be built bigger, carry more water, more rescue equipment, and more personnel than conventional fire trucks.

But that’s not why you’re reading about this on Electrek. You’re here to read about the Striker Volterra’s advanced battery tech, electric drive motors, and duty cycle-extending genset that effectively makes it a big EREV. More sympathetic I could not be, but — alas! — OshKosh hasn’t officially revealed those specs.

That said, it’s probably safe to assume they’re pretty similar to those used on the big Pierce fire fighting chassis developed for the Gilbert, Arizona fire department, which uses (you guessed it) an OshKosh-developed battery pack, electric drive system, and onboard diesel generator that can provide power to the electric system. That vehicle packs a 244 kWh battery pack good for up to six hours of operation on battery power alone.

The OshKosk electric Striker Volterra ARFF shown here is a Class 5 6×6 “rapid response” model capable of hauling up to 4,000 gallons of water (over 16 and a half tons, if you’re curious) and “firefighting foam” across an airport at speeds of up to 50 mph, which is positively moving for a machine this size. Plus, it supports zero-emission pumping, surpassing the NFPA required 2-hour continuous pump operation without using diesel.



Again, OshKosh hasn’t shared power and performance specs, but has confirmed that its electric drive Striker Volterra is 28% quicker to 50 mph than its Scania diesel-powered siblings, and that truck packs 550 hp and more than 1,750 ft‑lb torque. So — yeah. It’s got some juice.

Other key benefits, according to OshKosh, include a 75% reduction in total carbon footprint when compared to a conventional internal combustion engine ARFF vehicle based on the manufacturer’s estimated duty cycle, the eliminated need for long diesel idling times, and the ability to run on full-electric when entering, leaving and idling in the fire station, significantly reducing firefighter’s exposure to harmful emissions.

Electrek’s Take


Why Choose The Striker Volterra Electric ARFF Vehicle?
Striker Volterra ARFF; via OshKosh.

With the relatively short distances driven and extreme loads involved, airports present a nearly ideal use case for battery-electric vehicles in general, and their immediate off-the-line torque, improved efficiency, and ability to operate much more quietly than diesels (facilitating communications) could make all the difference in an emergency situation where lives are quite literally on the line.

Plus, as demand for on-road fossil fuels drops, airports and airlines (historically responsible for about 4% Earth’s global warming) are becoming a bigger and bigger slice of a rapidly shrinking pie when it comes to fossil fuel emissions.

Or, as OshKosk puts it: As airports continue to prioritize sustainability and operational efficiency, the Striker Volterra electric ARFF stands out as a forward-thinking solution that meets today’s demands while preparing for tomorrow’s challenges.

It’s a bit pitchy, but I couldn’t agree more.

Lexus RZ just got a +,000 bonus offer, making it its cheapest vehicle to lease

Thanks to a new $10,000 bonus offer introduced this month, the cheapest Lexus you can currently lease is now the 2025 electric RZ. Is it worth checking out?

The cheapest Lexus you can lease is the 2025 RZ

Lexus slashed over $10,000 off the price of the 2025 RZ compared to the 2024MY by introducing a new entry-level 300e FWD trim.

Following the launch of a new promotion this June, Lexus is offering up to $11,500 off 2025 RZ models. The RZ is now the cheapest Lexus vehicle you can lease, starting at $399 for 36 months. With $1,999 due at signing, you’ll end up with an effective monthly cost of $455. Not too bad for a nearly $45,000 luxury electric SUV.

The offer is for the 2025 Lexus RZ 300e FWD with an MSRP of $44,314. In comparison, the 2025 Lexus UX 300h FWD Hybrid, with an MSRP of $39,615, is listed at $349 for 36 months.

Although it’s a good deal compared to other Lexus vehicles, other luxury electric SUVs from Acura, Cadillac, and Genesis may still offer better value.

Acura is currently offering nearly $30,000 in lease cash on 2024 ZDX models in select states, with leases starting as low as $299 per month for 24 months. With $2,999 due at signing, the effective monthly rate is only $423. The ZDX offers up to 313 miles of range and more rear legroom (39.4″).

Cadillac’s new entry-level electric SUV, the 2025 Optiq, with an MSRP of $54,390, is listed for lease at just $409 for 24 months. However, it does include a $4,909 due at signing, resulting in an effective monthly rate of $614. The Optiq has up to 302 miles of range and 37.8″ of rear legroom.

2025 Lexus RZ model Starting Price* EPA-estimated Driving Range
RZ 450e AWD $48,675 220 miles
RZ 450e Premium AWD w/ 18″ Wheel $52,875 220 miles
