Prime vs. Hyundai Ioniq

all manufacturers have the odd poets day car,

we have had 3 or 4 recalls on the Ioniqs to fix various things to do with the hybrid system mainly

on the whole for such a new car I would say not many issues, biggest current issue appear to be the 12v battery failing in -25 to -30deg C in Canada

vast majority are good

 

is that the one built into the hybrid battery?

 

POETS day in the Ian Rankin John Rebus novel sense, meaning Pi$$ Off Early, Tomorrow's Saturday?

yep that's the meaning

 

no the 12v lead acid ones, interestingly we had we had a eastern Europe member say they had a 12v boost button, this is only fitted to the 12v LiPo cars, so they may be appearing outside US market now

I recently discovered that the ioniQ has no heat pump. This means that in the cold season ICE kick in any time you start the heater.. for me it would be a deal breaker.

 

The Ioniq PHEV only goes up to 50mph in EV. It is a blended PHEV like the PiP, and not trying to act like a pure EV. Hyundai probably felt a heat pump like the Electric has wasn't worth the cost and increased price. It starts at $2000 less than the Prime.

 

the Ioniq plugin will do more than 50mph in EV mode, it will sit at 60-70mph in EV, but if you need to accelerate it will kick in the ICE as the electric motor is only about 60ps, then once you settle into a constant speed cruise the ICE will cut out and you are back in EV again

my hybrid I have seen in EV at 80mph on a slight slope down, on the flat it will cruise in EV at upto about 65mph (over that the motor alone can't overcome the wind resistance so then the car uses it to assist the ICE to reduce fuel consumption), the phev motor is 50% more powerful

 

The Ioniq PHEV is on the top of my parents' short list to buy in a few months, but this may be an important issue.

Are you saying that no matter how cautiously, if you try to accelerate above 50mph in EV mode the ICE comes on? Or can one exceed 50mph with gentle acceleration and no ICE startup?

 

the faster the speed, the less spare capacity for acceleration, but once you settle to cruise again the ICE will cut out

many factors affect when the ICE runs, road speed, head wind, climate control settings (over 21/22 deg C the ICE runs more to help with heating if cold inside the cabin ) the accelerator / gas pedal position,

basically if your right foot requests more than 60PS of power from the drive train then the ICE will cut in until you ease off again, so for overtaking when you put your foot down the car will switch to hybrid (ICE + EV) then once you are round and ease off again it switches back to EV, the transition is pretty much seamless and the engine not that noisy,

if you are used to a prius the one thing people find unusual is the DCT gearbox changing gears in EV mode

basically a test drive is the answer to try it and see,

 

And any time you press the Defrost button on the Prime the 'ICE kicks in'..for me it would be a deal breaker.
If you want true EV performance during EV mode you need a better PHEV.

 

That's a misconception. The need for power defrosting is rare.

Here in Minnesota, I have the regular blower setting on window. That keeps it clear just fine, no engine.

In fact, the other day I fired up the heater from work, with the car still plugged in several blocks away. By the time I got to it, the snow on the windshield was all melted... with the engine ever starting.

 

I don't know about that. the prime makes pretty good use of the ice. if you live in a very cold area, carrying around the extra weight of an additional emergency electric heater may make sense, but for others, carrying around the additional weight for 8 months out of the year may not. phev's are by definition not supposed to be all electric. they're hybrids, not electric vehicles with an extra gas engine. they make use of the bits and pieces that they already have.

 

You get outstanding clean & efficient driving.

Sacrificing electricity, when you have an engine, doesn't actually make sense anyway.

 

The Ioniq PHEV is following philosophy Toyota had with the PiP. The car has an engine, so use it in order save grid charge for when it can be put to the best use.

This means using the engine under high demand from the driver, like accelerating on the highway, and making use of the engine's waste heat when it is cold instead of using electric. Thus saving the grid supply electric to provide the most amount of miles per kWh during the trip.

If you want a BEV experience with the assurance of a range extender, the Ioniq PHEV is not the car for you. If you want to reduce your gasoline use by shifting to grid electric, and don't care how the car does this exactly, it is worth a test drive.

 

yep

the PHEV philosophy is to provide EV mode where possible due to low power demand, then supplement that with the ICE when more power is needed,

for me who does a lot of long distance it then means most of my short journeys would be on electric, but I wouldn't have the range restriction and recharge times of a pure EV, so the short runs would no longer pull my overall average MPG down and I would be polluting a loss less due to fewer short runs using the ICE

 

Just curious, @Bluecar1 does the Ioniq uses an induction motor?

it uses a Permanent Magnet Synchronous Motor (PMSM), which are more efficient form of induction motor

Philosophy??? Is this in stone somewhere?

I can think of a PHEV that is 100% EV for the 'rated' +50 miles with 150 HP on tap.
It heats, cools, defrosts, preheats, etc, all on EV just like a BEV without that smelly, maintenance requiring, gasser springing to life intermittently.
Plus, is it good for a cold engine to power up and make lots of power immediately?
