Cybertruck vs Hummer EV

[Luke42]

The GMC Hummer reveal is October 20th and it will have “crab mode”. Four wheel steering returns to a GM truck with a complicated system that no truck owner has ever asked for. It’s nothing but marketing.

The Hummer EV isn't first GM truck 4-wheel steering:

They tried Quadrasteer, then they tried hybrid trucks. Cool technology in both cases, but not really a sales success for either one.

BTW, I own one of the 2-mode hybrid trucks and it's a pretty good truck. But, they didn't sell well.

That's GM for you. [shrug]

Many criteria to evaluate the Hummer ev on before concluding its any good, but Cybertruck advocates who don't acknowledge the massive girth of the Cybertruck are completely in denial, and ridiculous if they think Rear Wheel Steering is not a brilliant feature.

And one that would greatly benefit the Cybertruck if it had it.
Let alone how it benefits a vehicle in so many situations, on road, parking, and off road.

Here its demonstrated on Sports cars and Hi end Luxury (much shorter than the Cybertruck ) cars !




P.S. I think someone at Hummer has a nut fetish . . . 8 Wheel nuts !
I guess that's one way to handle the 15,600 Nm

I predict the Cybertruck will have 8 lug wheels AND might be classified as a medium duty vehicle.

Massive girth of the cybertruck? which other full size crew cab truck are you comparing it to?

Massive girth of the cybertruck? which other full size crew cab truck are you comparing it to?

You're absolutely right, its size is standard relative to all the full size crew cab truck. Perhaps even smaller than one or two particular ones.

But to me they are all massive, 231.7 inch's is Huuuuge to me.
For guys looking for a full size crew cab truck, the Cybertruck is awesome.
For guys like me who were never interested in a truck, they are drawn to the Cybertruck as brilliant All Purpose Adventure vehicle, but the 2nd Smaller version Cybertruck's proportions would be far more suitable.

Kind of like the expected proportions of the Hummer EV !


Post Edit:

P.S The automotive media Jalopnik, think the Hummer ev is "massive", and needs the rear wheel steering to help reduce its size (virtually) . . . . . . and its more than 2 ft shorter than the Cybertruck !!

"The new electric Hummer will debut next month to eventually do battle with the Tesla Cybertruck, if and when that latter vehicle materializes. GM had previously hinted one of the Hummer’s tricks would be crab-related, and now we get to see it in action a little bit.

Four-wheel steering, of course, has been around for decades. GMC likely imagines some off-road uses for its implementation on it for the Hummer, and parking, too, because this thing will be massive."

Adventure vehicle sounds great to me also and I would love to pair it with one of Australia’s awesome trailers or small caravans! I would love to know which ones a real Aussie are drawn to because it is really difficult to tell just off of what Youtube is showing.

Interesting. Looks like the Hummer EV will have a wireless harness, battery management system.

Where is Tesla on this? Will the CT have this?

ADI wBMS aims to eliminate wired harness for EVs

ADI has announced a wireless battery management system (wBMS), which enables automotive manufacturers increased flexibility to scale their electric vehicle fleets into volume production across a wide range of vehicle classes.

This is the first wireless battery management system available for production electric vehicles, and it will debut on General Motors’ production vehicles powered by Ultium batteries.

The implementation of ADI’s wBMS eliminates the traditional wired harness, saving up to 90% of the wiring and up to 15% of the volume in the battery pack, as well as improving design flexibility and manufacturability, without compromising range and accuracy over the life of the battery.

ADI’s wBMS includes all integrated circuits, hardware and software for power, battery management, RF communication, and system functions in a single system-level product that supports ASIL-D safety and module-level security building upon ADI’s proven industry leading BMS battery cell measurement technology.

By delivering high accuracy for the lifetime of the vehicle, the system enables maximum energy use per cell requiredfor best vehicle range and supports safe and sustainable zero-cobalt battery chemistries, such as lithium iron phosphate (LFP).

Additional system features enable batteries to measure and report their own performance, increasing early failure detection, and enabling optimised battery pack assembly. The data can be monitored remotely throughout the battery life cycle – from assembly to warehouse and transport through installation, maintenance and into a second-life phase.

ADI and General Motors recently announced a collaboration, bringing the wBMS technology to General Motors’ Ultium battery platform. The ADI technology helps ensure scalability of the Ultium platform across General Motor’s future lineup, which will encompass different brands and vehicle segments, from work trucks to performance vehicles.

The wireless means fewer wires, but it also means that stuff we drive past is even more likely to interrupt internal systems.

At that point, why aren't they just pumping a signal into a shielded bus?

I see some advantages, but lots of disadvantages for an industrial vehicle. And wiring harnesses can also be receivers for interference, too, so they're not automatically better.

[Frank W]

I agree with you on that and will add that I found the statement “By delivering high accuracy for the lifetime of the vehicle” odd because they have nothing to go on as far as I know.

The cybertruck is not massive for all of us that have 3/4 ton or 1 ton trucks and want to replace with the cybertruck. If anything, it is a downsizing for us. I know the CT is smaller than my current Ram 2500 megacab diesel. A lot of the tight turning radius things we do offroad could be well handled with torque vectoring of the back wheels, but rear axle steering makes sense for some other things. I mostly envision it being helpful when going slow on pavement, tbh. I don't know how quadrasteer would affect towing capability. If it downgrades the capability for towing, I'm out.

 

[Crissa]

With electric, it's unlikely to downgrade towing capability.

Back when the M3 was first revealed I put a deposit down but then decided that it was just too small for what I wanted so the wait for the CT is really difficult. I have been waiting for years already but the upside to the waiting is I will be able to pay cash. Still the waiting is tough but I am 100% committed to the CT ONLY!

 

[Luke42]

I don't know how quadrasteer would affect towing capability. If it downgrades the capability for towing, I'm out.

Quadrasteer was advertised as being more stable for towing, though I don't know if it affected the tow rating.

If I remember the commercials from the 1990s properly, Quadrasteer has a mode where the vehicle crabs at high speeds for trailer stability.

Here's a video showing how Quadrasteer works and a towing demo:
He starts saying useful things about the towing mode around 7:11.

I've never driven one, though.

GM could do worse than using an updated version of the Quadrasteer system.

 

[firsttruck]

Can not use Rivian tank turn on hard surfaces or softer surfaces you do not want too tear up. Tank turn really can only be used on slick or slippery surfaces and is no use for towing.
Quadrasteer sounds much better.

Will Quadrasteer have a second life for Extreme Towing and Handling

Torque vectoring via traction control can be used to mimic quadrosteer at speed, but no idea if they can implement it.

Lots of things are 'plausible' or 'possible' but very difficult or impossible to implement within real constraints.
