Great video on a bad concept. Lets explore the ways this will have no long term benefit. #1 This thing once out of warrenty it is probably a 4k part if you have to replace it yourself#2 Start/stop is dumb but now instead of replacing a burned up 200 starter you will be replacing this thing all to save literally a few drops of gas at a stop light#3 Do you honestly think a 8/10 rib belt could hold 130 ft lbs of torque in addition to all the pre-existing accesories? No it couldent not unless it was a cog belt which it is not. #4 Unless this was mounted directly above the center line of the crank shaft and driven by a cog belt it will not last as a power enducing device. Once any substantial load is generated by it or placed aginst it the cast aluminum mounting brackets will likely begin to weaken. If it is not mounted inline with the crankshaft the torsional load placed aginst it will be excessive All this crazy over engineered stuff looks good on paper just give it a few years to start breaking down.

You are the only one to tell us does the A/C work while the motor is off. And IT DOES NOT. Thank You Then eTorgue is worthless here in South Florida. Much rather had an Eletric a/c no need for the torque help much rather save gas while enjoying a pickup. We have allot of of traffic here is Miami, Fla. 98. 5% of the year we are using our vehicle A/Cs. My current Hybrid Ford Cmax is awesome; but looking to buy a Pick Up; seems the 2018-2019 F-150 2. 7 Ecoboost will have to do. I am towing 4500 lbs fully loaded. But need it as an everyday driver. How awesome a semi hybrid in a Pick Up that focuses just on the whole gliding, the drive through and of course the start and stop The amount of gas saved just in those driving conditions here in South Florida would go so far

Alex: Nice job (as usual. Question: Ive searched, including the comments below and the official Dodge site (and others, but cant find a straight answer. Can you list the horsepower (HP) ratings of the three Motor/Generators (MG) please? I know you provide the torque and voltage but HP seems to be calculated from those figures based on RPM (unless Im mistaken. Without the MG RPM figures very tough to guess at the HP equivalent value. I get why torque is the key figure in this use case but I have my reasons for wanting to know the HP. Can you help a nerd out? :) Watts at full power out (in motor mode) would provide the same answer if you have that. Thank you

48V hybrids will be a really big thing. I expect significant part of the vehicles will have that within like 5-8 years (1/3-2/3 of all non EV non PHEV non HEV. Alex, some mild hybrids will likely be able to drive the vehicle in start-stop traffic (5-10kW is enough for low speed crawling. But motor must be further down the drivetrain. Therefore be prepared for that. Mild Hybrids can move on electric propulsion. And electric AC. And electric PS. And electric turbocharger. And electric heating even. So every time new 48V vehicle is being reviewed, mention those capabilities: )Abbreviation for this class of vehicles should be MHEV.

Added complexity. for the added advantages you are mentioning? NOT WORTH IT. All this e-torque extra parts eventually needs repairs and replacements and the minor fuel economy increase youre mentioning is never going to cover for the extra costs of any all those extra parts. NEVER. START/STOP put tons of stress on partss like the alternator and the starter motor and the exhaust system filtration. people in Europe are paying the price for this fuel economy nonsense with horrendous parts costs and reliability.

Im a little confused, probably because Im from Europe and different engines are available here. Is this eTorque the same engine line that gets sold under the name E. torQ here in Europe and in South America? Or is this something new for the US market? The E-torQ sold in South America is a petrol / ethanol flexifuel engine. Here in Europe we use it as a regular gasoline engine available on a few FCA models.

Great video and very welcome - Ive been waiting for this since BMW showed their performance hybrid in the i8. You said the total weight is 100 lbs, which means its doable for small cars. How long until Mazda prototype a 3 cylinder plus this system to add torquey fun and efficiency, in the MX-5? Any indication that Mini or other small car brand are thinking this way? Thanks for another great video.

Firstly love your new technical explanation videos Alex. Secondly this system reminds me of the old GM e Assist used in the 2. 4L Malibu and Regal but running off the 48v system instead of the 12v. Honestly e Assist was so mild it didnt live past 2 model cycles which brings me to this; is it really worth the cost in the age of integrated starter motors and hybridization?

This is where government regulations drive bad engineering. Designed specifically to improve the MPG during the CAFE testing, not real life. Motor runs when the vehicle stops if the A/C is running. not much help in the south or the summer. No benefit at highway speeds. If it were a no cost option it would be worth it. Great explanation Alex

While I not been able to relocate the video that I viewed back in Jan/Feb about the eTorque system it explained that the system will only generate its additional torque into the drive line for about 1 second on start up. I believe some are thinking that this 130 ft lbs in the Hemi is in addition to the 410 lb rating of the engine.
