eTorque will be required on Hemi soon

[IvoryHemi]

Appears the Hemi will soon only be available with the 48V system. Noticed this slipped into today’s EV presentation..

“By 2025, all vehicles in the Ram lineup will have some degree of electrification, Koval told investors during an event to outline the future EV plans of Stellantis”

Not a surprise for 1500, but have to wonder if they are referencing Ram HD vehicles too?

They are trying to go to the better 48V system, that's probably going to push them that direction.

What is this "better 48v system" you speak of?

 

[Trooper4]

Wonder why they all don't just go with a small-ish engine to power a generator and put four corner electric motors in all vehicles. Or even one and a constant velocity transmission.

What is this "better 48v system" you speak of?

That change is driven by the introduction of 48V direct current systems to work alongside the 12V systems we have used for decades.

Modern cars now consume much more electrical energy than they used to due to features like climate-control, driver-assistance computers, and complex infotainment systems.

The shift to 48V minimizes resistive loses of energy, allows higher currents, and greater power delivery, so things like window demisters and heated seats can be more effective by working more quickly.

But much more important, adding 48V systems enables mild hybridization, which in turn means greater fuel economy and reduced emissions on vehicles at a relatively low cost.

The move toward hybridization meant the use of such systems to aid the internal combustion engines and increase efficiently by driving auxiliary functions.

These may be E-Turbos, regenerative brakes, electronic power steering racks or water pumps, which use electric motors rather than using a power take-off from the engine.

Understanding the Shift to 48V Systems Happening in the Automotive Industry

We live in times where there is a shift from traditional combustion engines to hybrid and fully electric vehicles. Everyone experiences this but few of us are aware of the fundamental change in vehicle architecture.

Modern vehicles are consuming increased electricity, which calls for a high-performance on-board power supply system. The 48V boardnet delivers sufficient power and offers a wide range of options for optimizing propulsion in terms of fuel economy, emissions, and dynamic driving performance. It can be implemented economically while maintaining power output.

BorgWarner has a large number of 48-volt technologies in its portfolio, each offering significant efficiency gains. Further benefits include simple integration, lower weight, and reduced space requirements, which permit more flexible usage of the installation area. As highlighted during both the preliminary development and series development phases, fuel savings of up to 20 % can be achieved with corresponding improvement of the exhaust emission values in real-world driving conditions. Our solutions can also optimize passenger comfort through improved response or better power transmission. With our diverse product portfolio and comprehensive system expertise, we are capable of developing this potential for our customers. Many of our 48-volt technologies are already proving their value today in the production cars of leading vehicle manufacturers.

48V systems also means it’s possible to run higher gauge (thinner) wire since the current (amps) will be lower for the same power (watts). Generally, 6 sizes smaller: 6 gauge instead of 0 gauge, 10 gauge instead of 4 gauge, etc.

20% fuel savings?!

20% fuel savings?!

You realize thats a percentage right?
20% on a Ram 1500 would be 2-3 mpg increase, that's not unrealistic

Yes I know. 17 (or 20) mpg for non-eTorque vs 20.4 (or 24) mpg for with eTorque is completely unrealistic

Far as I can see, biggest advantage is in the city, it doesn't activate at any point when you're cruising down the freeway so I agree, have no idea how they're planning to increase HW mileage that much.

Wonder why they all don't just go with a small-ish engine to power a generator and put four corner electric motors in all vehicles. Or even one and a constant velocity transmission.

They did this with the Volt; it's an electric car, which plugs in too. When it runs out of juice the little 4 banger kicks in and both charges the battery and provides additional power to the wheels at the same time.

It's a great technology but suffers from 2 problems;
- chevy economy class build quality
- just look at it, people want a car that looks great, electric shouldn't change that (Tesla got that right at least)

My Prius Prime is the same, but they need to get the electric miles up above 30 miles. Don't know about the others, as they may have a larger capacity and run on electric only for a longer period. Can't complain about the wife's car though, as she mostly uses it on short trips around town and averages 200mpg as a plug-in hybrid. But in a truck, it is going to have to be a whole different deal.

They increase highway milage the same way the did when the world was going to run out of oil in 10 years back in the 70's. They just neutered vehicles so they were anemic and did not use gas. In 1978 Ford put a 400ci engine in the Torino for an amazing 160 hp. That was without a computer cutting things back.
