Hyundai Ioniq - coming next year?

[DaveofDurham]

Just saw this article about the Hyundai Ioniq - reported to be coming soon with gas hybrid, plug-in hybrid and all electric versions.

I'll be interested to see more about it. My guess is that it will have a similar hybrid system to the Sonata Hybrid; two electric motors and the ICE tied together in a more traditional automatic transmission; though Hyundai may try pairing it with their dual clutch transmission for better city fuel economy (like VWs hybrids). With this being the case, I'm going to guess it will be somewhere around 50 mpg, with better highway mpg than city.

CleanMPG has a couple of videos on the Ioniq from the New York auto show, the second an interview with Micheal O'Brien, Hyundai America's VP of Corporate and Product Planning. The hybrid will have a 1.6L,104 HP ICE and a 43 HP electric motor, combined with a 6 speed DCT; and the electric motor in the plug-in is upgraded to 60 HP. The electric version will be 120 HP electric engine and will be able to fast charge the battery to 80% capacity in 20 minutes. Apparently Hyundai is expecting 57 mpg combined fuel efficiency from the hybrid, more than a 25 mile range with the plug in hybrid, and 110 miles of range (or greater) from the electric. Looks like it will be a hatchback, design very similar to the Elantra but with more aerodynamic styling, with 0.24 coefficient of drag. No pricing is available yet, though the Hybrid and Electric version are expected by the end of the year, with the plug-in hybrid in the spring of next year.

Looks cool.  Doesn't appear to have as much power as the C-Max.  Amazing how similar the interior design is.  I would imagine that passengers sit much lower than the C-Max.  Headroom can't be as good.  Would be curious regarding cold-weather performance.

It is obviously lower, it has to be to get the 0.24 Coefficient of Drag, which means both sitting lower and having less headroom. It will be interesting to see what kind of power it has, though it will have less than the C-Max, it will be more interesting to see how it compares to the Prius in terms of power. OTOH, I'm guessing that some of the reviews will claim it is "more fun to drive", even than the C-Max, because of the DCT rather than the eCVT. It will also be impressive if it can actually get the 57 mpg Hyundai is claiming.

 

Kia is making a more direct competitor for the C-Max, the Niro, built off the same powertrain and chassis, there is a thread on the Niro here. The Niro is shaped, and appears to have similar interior and headroom to the C-Max but still get 50 mpg based on Kia's claims. It won't be available in the US until early next year, it will be interesting to see what the final version looks like and the specs.

 

As for cold-weather; they both will likely work similarly to all hybrids, where fuel economy suffers. Though Hyundai does (at least from what I've seen) a better job of closing off their engine compartment to keep the engine warm -- and the thermal efficiency Hyundai is claiming for this power train may help. Regardless, you'll still have a cold weather "penalty."

It is obviously lower, it has to be to get the 0.24 Coefficient of Drag, ...

Just to be clear, Coefficient of Drag has nothing to do with area (or height of an object).  For example, a large sphere and a small sphere would have the same C_d.   What makes the Drag force different between a small sphere and a large sphere is the cross sectional area of the spheres.

 

So, a lower (height-wise) car does not mean a lower C_d nor does a lower C_d imply a lower height car.  The lower C_d of the Hyundai Ioniq simply implies it has a better aerodynamic form or shape  to air flow than the C-Max (assuming aerodynamic "skin" or friction affect is the same).

While I understand, the fact remains that a car -- particularly with limitations on the shape, both to provide a roomy interior and good handling on the road -- really limits the height a car can be and still maintain a low Coefficient of Drag. To make height not a factor you would likely have to do things that would make a car impractical for a person to drive, much less want to buy.

Re-read Plus 3's post, as he's exactly right.

 

Drag Force = Drag Coefficient X Cross-sectional Area, by the definition of the Drag Coefficient.

 

The "limitations on the shape" you reference, such as height, effect the cross-sectional area, and so total drag force, but not Cd.

 

Have fun,

Good (perhaps great)  looking sedan, handsome - but slooooow, did I hear 9.5 seconds, argh !

 

Should be a good seller, but not for taller folks, or for four adults - the rear legroom looked horrible and the headroom likely claustrophobic.

I would bet that it is similar weight to the Prius, that is about 600 lbs lighter than the C-Max. That alone makes for a lot of MPG.
