Hi all, Starting to look into replacing our 2012 Prius v wagon at some point. I stumbled upon the Weber Auto video below that explains how the Honda e-drive transaxle works...and came away impressed. It seems like a really solid system. Just wondering if anyone has a vehicle with this system and your experiences with it. According to the video the Honda CR-V Hybrid, Accord Hybrid, Insight Hybrid, and Clarity Plug-In Hybrid use this system. However, the video is from 2020 so possibly more vehicles use it now ( i.e. - the Honda Fit hybrid ). Thanks in advance!
Don't all current Honda hybrid uses an e-drive system or whatever they call it? The older IMA became notorious for the premature traction battery failure (which was not so much due to the IMA system but more due to the poor battery management in certain year models of Civic Hybrid). I bought our son a used 2015 CRZ which is one of the last models with an IMA system as I understand it.
It is a poor substitute for the Toyota system. First real world mpg on the CRV hybrid is no better than the more common 1.5 Turbo engine. The Honda system will operate the gas engine at high rpm even when you are driving slow when the battery is low creating an odd disconnect between the current vehicle load and the engine. As always, the newer generation tells the story by attempting to resolve the earlier flaws. Honda is introducing their 4th generation hybrid in the 2023 CRV. Very little details so far but one source suggests it will improve mpg. Direct injection, two electric motors, higher speed operation (from 86 mph max to 115) and better engine speed correlation. From Honda News Release New More Powerful, More Capable Hybrid Models For a sportier driving feel, CR-V Sport and Sport Touring feature an all-new 4th-generation two-motor hybrid-electric system with a newly refined 2.0-liter Atkinson cycle 4-cylinder engine that adds direct fuel injection and is mated to a pair of electric motors that are now mounted side-by-side. This new configuration allows for the use of a larger propulsion motor with increased torque output. Combined system output is 2041 hp (a 3 hp increase, ISO net), while the traction-motor peak torque rises to 247 lb.-ft. of torque (up 15 lb.-ft.). The hybrid-electric system is more refined at highway speeds and for the first time offers up to 1,000 pounds of towing capacity. Linear Shift Control elevates the driving experience by mimicking the vehicle speed-linked rev feel associated with a conventional drivetrain shifting gears at wide open throttle. The new hybrid-electric system also allows for a substantial increase in continuous maximum speed—which climbs from 86 mph to 115 mph.
The Fit/Jazz uses a parallel hybrid system similar to, but predates, the one in the the Ioniq and Niro. It is mated to a DCT. That system is the core of the AWD one that was once available in some Acuras here. It added a motor to each rear wheel.
After reading some 'real world' accounts, Honda's latest hybrid system does have it's merits. Some folks are getting awesome MPG with Honda's system when you drive them 'gently'. However, for North American high speed freeway driving, Toyota's system definitely seems better. I guess you have to work with the quirks of any hybrid system for max MPG. Honda's hybrid system does seem pretty solid as far as reliability goes though ( watch the Weber auto video ). Probably the second best system outside of the Toyota HSD. Anyway, at least it seems like Honda's system is a viable alternative. I absolutely will never go with the dual clutch system that Hyundai and others go with.
Other parallel hybrid systems, like the one in the Tundra, are mated to a traditional step automatic.
I’ve got about 40% left on my second tank of gas on an Accord Hybrid. My regular commute is about 12 miles each day, city traffic during rush hour. I’m averaging 53 MPG on my current tank. The official fuel economy rating is 48 MPG city.
Nice! How does it do on freeway trips at 70MPH or above? That is where I've heard Honda's hybrid system can be inferior to Toyota's.
Assuming the mpg's you're seeing are displayed, do a calculation as well, see if it agrees. With our 06 Civic Hybrid displayed mpg either matched or was slightly pessimistic, which is commendable. Toyota OTOH, BS's about as much as they can get away with, 7~8% on our 3rd gen.
