With the Prime it sounds like it would make more sense to carry an electrician/or/tech guy around with you in the back seat rather than a spare tire.
I've had 2 terrible flats in my GenIII, both in the first year of owning it. A spare would have been my only option. I checked out a Prime today at a dealership (first time I'd actually seen one) and wondered about stowing a donut spare behind one of the front seats on the floor. I tried to remove one of the rear headrests and couldn't figure out how - that option needed to stow the donut on the floor. Can the rear headrests be removed? The salesman didn't know either (go figure). I didn't find the raised deck all that objectionable considering I very rarely load the back with gear, other than the annual road trip vacation. I can deal with the reduced space I guess. I also wanted to check out the little folding tie-down hooks in the back since this model doesn't have the more conventional D-rings for bungie straps. With the tonneau(sp?) cover bar removed, I can see using those mounting knobs as well for tying down gear.
Thanks. I'll try that if I ever see another Prime at another Chicago area dealership. The one I was at this morning probably has a restraining order out on me by now.
You guys are jinxing yourselves. BTDT and got the flats afterwards to prove it! Luckily I bought a mini-spare for my Energi because I somehow got a gash on inside wall of a rear tire. Due to having to buy a new one online and shipping issues, it took well over a week to get a replacement installed. 98% of the time I keep the spare at home and only take it on very long trips where it is usually carried outside the car on a hitch/cargo carrier with other stuff. For storing inside the car, I highly suggest one of these cheap covers intended for long term UV protection for parked RV's or trailers: Camco 45359 Vinyl Spare Tire Cover - Google Search
In general, I'm not a fan at all of the trunk.. The 'raised floor' looks kind of half-assed to me. I'll see what the IONIQ plug-in looks like and reserve further judgement. However, from what I'm seeing, a pic the IONIQ EV trunk can be found here : 2017 Ioniq Electric Vehicle (EV) - Photos - Hyundai Motor America Newsroom The IONIQ hybrid has the same trunk space specification...so I'm assuming it looks the same. If these photos are legit, I like the design a LOT more than the Prime. It's almost like Toyota designed the hybrid Prius and then tried to shoehorn a larger battery into the Prime..It's just a very odd trunk... Edit: I'm not trying to sound too negative - for the most part I love the Prime.. However, the trunk is one of the things that turns me off about it...especially when competitors have appeared to have 'solved the problem'.
For me, the lack of actual storage space isn't so terrible since square footage is more important than cubic footage for me. Though, I will say that oftentimes when I do store something in my trunk, it's difficult/impossible to pull the cover over it, and this is less than great. Sometimes, it's nice to be able to store things back there and out of sight, but the raised floor of the trunk can limit the ability to do so.
Dealer supplied, part of sale, full size, it does not shift around at all. No effect on fuel economy, I drive EV all the time. 199.9 Mpg.
I saw the Ioniq plug-in at the Detroit auto show last month. The trunk seemed a little bigger than Prime, but that could have been just a trick of the eye, I didn't have a tape measure or anything. Only drawback to the Ioniq trunk is that you would have to lift luggage in and out over the lip, although I don't remember if it was as deep as the photo in your link. But either way Prime might be easier to get luggage in and out of.
Toyota will gladly sell you a spare. Tire sits on back of folded right rear seat back, and is below front seat level.
The Trunk of the Ioniq Plug-in seems to be quite a bit more spacious than the Primes . Sombody apparently measured 33 cm (~13 inches ) up to the cargo cover and keep in mind that it only was a pre-production model,so it's possible they allready further improved it . As much as I appreciate Toyota for their Prius,they really messed up big time with the trunk . Here's a picture of the Ioniq' Plug-in trunk :
You should look at European cargo space specs to get a more accurate feel for Prime vs. IONIQ space. U.S. uses a funny metric called "EPA Cargo Space" which allows hatchbacks some "flexibility" in dividing up space between passenger space and cargo space. One useful U.S. spec however is EPA Total Interior Space. As far as pre-production IONIQ, if I recall it has more total space than Prime.
