Formula E unveiled its new “Gen3 EVO” car, an update to the Gen3 car which debuted last season, ahead of the Monaco ePrix this weekend.

The new car will be used for next season, and is basically a mid-cycle update of the Gen3 car which has been in service for last and this season. The succeeding Gen4 car is not expected until 2027.

The Gen3 car was introduced as both lighter and more powerful as the previous generation car, with a lot of promises about how much quicker it could be in the races.

It also utilized some pretty unique design ideas. The biggest difference is the addition of a front motor, but this motor was only used for braking, and conversely, the rear friction brakes were entirely deleted and instead the rear axle is braked only by the rear motor using regenerative braking, for a total of 600kW regenerative braking power.

However, The Gen3 didn’t turn out to be all that much faster. This often happens with new racecars as teams get used to tuning and using them, but teams struggled to harness the extra power available to them.

At the same time, the series switched tire providers, and the new tires may have proven to be a limiting factor.

Now, the Gen3 car is hoping to fix both of these problems at once. Not only has Hankook provided stickier tires (with 5-10% more grip, and made of 35% recycled materials) which should help to harness some of the car’s additional power, Formula E has also taken the rather unique move (in the world of formula cars) of activating the Gen3 car’s front motor for thrust, not just regen – thus making its cars all-wheel drive.

The Gen3’s inclusion of a front motor left many thinking – ourselves included – that it would inevitably get activated not just for regen, but for power delivery.

There have been all-wheel drive single seater open wheel cars in the past, but it has only been tried a few times. Currently, other open-wheel single seaters (like F1, IndyCar and the like) are rear-wheel drive only.

AWD has been popular on road cars recently, because it enhances acceleration and drivability. And on EVs, it’s quite easy to add, because you can just slap a second motor on the other axle and run a few cables to it, rather than needing to run driveshafts and gearing mechanisms all through your car to transfer the power from a single combustion engine to two separate axles.

However, sportscar and racing enthusiasts have often preferred rear-wheel drive because it makes cars more squirrelly and difficult to control, showcasing driver skill more readily.

So Formula E is going to allow all-wheel drive only in certain situations. During qualifying duels, race starts, and during the activation of “attack mode,” a temporary 50kW power boost that each driver gets at certain points in the race.

One complaint about the Gen3 cars was that attack mode was hard to use, because the car felt like it couldn’t properly utilize that additional 50kW. By activating the front motor, this should give drivers a huge advantage – quicker acceleration through and out of corners is an enormous benefit.

While 0-60 numbers don’t matter a lot for a racecar – they’re only ever at 0mph at one point, at the start of the race, after all – acceleration is still important for exiting corners, and gives you a lasting benefit for the entire straight if you can get a better exit than another racer. And the Gen3 EVO boasts a truly impressive 0-60 number: 1.82 seconds.

This 0-60 time is 30% quicker than an F1 car and 36% quicker than the Gen3 car, thanks to that front motor helping pull the car forward with 4 contact patches instead of 2.

In addition, the design of the car has changed somewhat. The nose and front wing have been redesigned from the (perhaps overly) angular design of the original Gen3 car. Over the last season and a half, cars have struggled with front wing damage, so hopefully the new wing will be a little more durable.

All told, Formula E says that the new car could be 1-3 seconds faster per lap, depending on circuit and whether the AWD system is in use. This would be a pretty massive improvement as far as laptimes go, but we’ll have to see how it plays out when next season comes around.

Now, if only we could also see that 600kW mid-race charging they’ve been working on…

The new Gen3 EVO car will start seeing use next season, but if you want to see the current Gen3 car in action, you can watch it this weekend at the Monaco ePrix.

The race proper starts at 6am PDT, 9am EDT, 1pm UTC, and 3pm local Monaco time on Saturday April 27. In the US, all sessions other than the race will be available on the Roku channel, practice sessions will be on Formula E’s YouTube, and the race will be on CBS/CBS Sports Network.

Caterpillar is putting MASSIVE 240-ton electric haul truck to work in Vale mine

Caterpillar is putting MASSIVE 240-ton electric haul truck to work in Vale mine

Mining company Vale is turning to Caterpillar to provide this massive, 240-ton battery-electric haul truck in a bid to slash carbon emissions at its mines by 2030.

Caterpillar and Vale have signed an agreement that will see the Brazilian mining company test severe-duty battery electric mining trucks like the 793 BEV (above), as well as V2G/V2x energy transfer systems and alcohol-powered trucks. The test will help Vale make better equipment choices as it works to achieve its goals of reducing direct and indirect carbon emissions 33% by 2030 and eliminating 100% of its net emissions by 2050.

If that sounds weird, consider that most cars and trucks in Brazil run on either pure ethyl alcohol/ethanol (E100) or “gasohol” (E25).

“We are developing a portfolio of options to decarbonize Vale’s operations, including electrification and the use of alternative fuels in the mines. The most viable solutions will be adopted,” explains Ludmila Nascimento, energy and decarbonization director Vale. “We believe that ethanol has great potential to contribute to the 2030 target because it is a fuel that has already been adopted on a large scale in Brazil, with an established supply network, and which requires an active partnership with manufacturers. We stand together to support them in this goal.”

Vale will test a 240-ton Cat 793 battery-electric haul truck at its operations in Minas Gerais, and put energy transfer solutions to a similar tests at Vale’s operations in Pará over the next two-three years. Caterpillar and Vale have also agreed to a joint study on the viability of a dual-fuel (ethanol/diesel) solution for existing ICE-powered assets.

Vale claims to be the world’s largest producer of iron ore and nickel, and says it’s committed to an investment of between $4 billion to $6 billion to meet its 2030 goal.

Cat 793 electric haul truck

During its debut in 2022, the Cat 793 haul truck was shown on a 4.3-mile test course at the company’s Tucson proving grounds. There, the 240-ton truck was able to achieve a top speed of over 37 mph (60 km/h) fully loaded. Further tests involved the loaded truck climbing a 10% grade for a full kilometer miles at 7.5 mph before unloading and turning around for the descent, using regenerative braking to put energy back into the battery on the way down.

Despite not giving out detailed specs, Caterpillar reps reported that the 793 still had enough charge in its batteries for to complete more testing cycles.

Electrek’s Take

Electric equipment and mining to together like peanut butter and jelly. In confined spaces, the carbon emissions and ear-splitting noise of conventional mining equipment can create dangerous circumstances for miners and operators, and that can lead to injury or long-term disability that’s just going to exacerbate a mining operation’s ability to keep people working and minerals coming out of the ground.

By working with companies like Vale to prove that forward-looking electric equipment can do the job as well as well as (if not better than) their internal combustion counterparts, Caterpillar will go a long way towards converting the ICE faithful.

Argonne Nat'l Lab is spending big bucks to study BIG hydrogen vehicles

Argonne National Laboratory is building a new research and development facility to independently test large-scale hydrogen fuel cell systems for heavy-duty and off-road applications with funding from the US Department of Energy.

The US Department of Energy (DOE) is hoping Argonne Nat’l Lab’s extensive fuel cell research experience, which dates back to 1996, will give it unique insights as it evaluates new polymer electrolyte membrane (PEM) fuel cell systems ranging from 150 to 600 kilowatts for use in industrial vehicle and stationary power generation applications.

The new Argonne test facility will help prove (or, it should be said, disprove) the validity of hydrogen as a viable fuel for transportation applications including heavy trucks, railroad locomotives, marine vessels, and heavy machines used in the agriculture, construction, and mining industries.

“The facility will serve as a national resource for analysis and testing of heavy-duty fuel cell systems for developers, technology integrators and end-users in heavy-duty transportation applications including [OTR] trucks, railroad locomotives, marine vessels, aircraft and vehicles used in the agriculture, construction and mining industries,” explains Ted Krause, laboratory relationship manager for Argonne’s hydrogen and fuel cell programs. “The testing infrastructure will help advance fuel cell performance and pave the way toward integrating the technology into all of these transportation applications.”

The Hydrogen and Fuel Cell Technologies Office (HFTO) of DOE’s Office of Energy Efficiency and Renewable Energy is dedicating about $4 million to help build the new Argonne facility, which is set to come online next fall.

Electrek’s Take

It’s going to be hard to convince me that the concentrated push for a technology as inefficient as hydrogen fuel cells has more to do with any real consumer or climate benefit than it does keeping the throngs of people it will take to manufacture, capture, transport, store, house, and effectively dispense hydrogen gainfully employed through the next election cycle.

As such, while case studies like the hydrogen combustion-powered heavy trucks that have been trialed at Anglo American’s Mogalakwena mine since 2021 (at top) and fuel cell-powered concepts like Komatsu’s medium-sized excavator (above) have proven that hydrogen as a fuel can definitely work on a job site level while producing far fewer harmful emissions than diesel, I think swappable batteries like the ones being shown off by Moog Construction and Firstgreen have a far brighter future.

Speaking of Moog, we talked to some of the engineers being their ZQuip modular battery systems on a HEP-isode of The Heavy Equipment Podcast a few months back. I’ve included it, below, in case that’s something you’d like to check out.

Velocity truck rental adds 47 high-speed truck chargers to California dealer network

Velocity truck rental is doing its part to help commercial fleets electrify by energizing 47 high-powered charging stations at four strategic dealer locations across Southern California. And they’re doing it now.

The new Velocity Truck Rental & Leasing (VTRL) charging network isn’t some far-off goal being announced for PR purposes. The company says its new chargers are already in the ground, and set to be fully online and energized by the end of this month at at VTRL facilities in Rancho Dominguez (17), Fontana (14), the City of Industry (14), and San Diego (2).

45 120 kW Detroit e-Fill chargers make up the bulk of VTRL’s infrastructure project, while two DCFC stations from ChargePoint get them to 47. All of the chargers, however, where chosen specifically to cater to the needs of medium and heavy-duty battery electric work trucks.

The company says it chose the Detroit e-Fill commercial-grade chargers because they’ve already proven themselves in Daimler-heavy fleets with their ability to bring Class 8 Freightliner eCascadias, Class 6 and 7 Freightliner eM2 box trucks, and RIZON Class 4 and 5 cabover trucks, “to 80% state of charge in just 90 minutes or less.”

At Velocity, we are not just reacting to the shift towards electric mobility; we are at the forefront with our customers and actively shaping it. By integrating high-powered, commercial-grade charging solutions along key transit corridors, we are ensuring that our customers have the support they need today. This charging infrastructure investment is a testament to our commitment to helping our customers transition smoothly to electromobility solutions and to prepare for compliance with the Advanced Clean Fleets (ACF) regulations.

David Deon, velocity president

Velocity plans to offer flexible charging options to accommodate the needs of different fleets, including both managed, “charging as a service” subscription plans and self-managed/opportunity charging during daily routes. While trucks are charging, drivers and operators will be able to relax in comfortable break rooms equipped with WIFI, television, snacks, water, and restrooms.

Electrek’s Take

While it feels a bit underwhelming to write about trucking companies simply following the letter of the law in California, the rollout of an all-electric, zero-emission commercial trucking fleet remains something that, I think, should be celebrated.

As such, I’m celebrating it. I hope you are, too.
