Hyundai Readying New EREV Models Starting in 2027

hyundai readying new erev models starting in 2027

Hyundai has built quite the electric vehicle business over the last few years, but its upcoming release takes its electrification efforts in a different direction. The automaker is expected to announce a new extended-range EV, its first, which will go on sale in 2027.

Extended-range EVs (EREVs) function as electric vehicles but use a gas engine as a generator to charge the batteries, extending the range. There haven’t been many such vehicles available in the United States, but that’s changing with new models from Ram and others in the coming months.

Hyundai plans for an impressive range number with the new system, saying, “Launching in 2027, Extended Range EVs (EREVs) will utilize high-performance batteries and motors to deliver EV-like driving experiences with more than 600 miles (960km) of range through optimized battery-engine integration.”

In addition to boosting range, EREVs utilize smaller batteries, which could make them slightly more affordable than full battery-electric models. Hyundai’s statement reads, “Unlike conventional EREVs, Hyundai’s approach utilizes in-house high-performance batteries, achieving full EV power performance with less than half the battery capacity, improving accessibility while maintaining exceptional range and performance, and eliminating range anxiety.”

Hyundai also noted that its EREV tech would extend to Genesis products in the future. It plans to expand availability of the EREV powertrain to more than 18 models by the end of the decade, with the first Genesis models being introduced next year.

We do agree on plugging in!

But what frustrates me is that the "nuts and bolts" DO matter to how people use the vehicles in the real world. A series hybrid, whether you call it an "EREV" or not, is going to be the best tech for people who aren't ready for pure EV but do most of their driving in a dense city. A conventional hybrid with a single motor behind an automatic transmission may be the most cost-effective tech for people who do most of their driving on the highway. Plug-in may or may not make sense depending on how much a driver drives during each driving day. And so on.

That's why we need a way to talk about these things that is actually comprehensible to the average person, and can eventually work its way into the same every day knowledge base that currently contains things like "Cars need oil changes" and "Big trucks get bad gas mileage."

  I'm an average person and I concur.

  Wrong.

  I would suggest that fewer than 1% of the car buying public has any interest in or knowledge of the nuts-and-bolts and wire twisting information.
  That maybe as many as 1% of the buyers do, is no reason to cater to them in any way.
  And MC, after everything you've said I will forever chase after your accepting a gasoline engine and its nasty fumes and need to stop every few days at one of those smelly gas stations, taking all that time, and all of its maintenance requirements at all those Bhopal-level service stations taking your time away from you.
  In your world, there's no reason for any of that nonsense and annoyance and expense to exist.
  And in the end, you have gasoline working against the mass of that battery, just to propel the car and its occupants, wasting fuel. Isn't that the argument?

  "Wrong."
  Then why has the series hybrid completely won the battle in the urban transit bus and garbage truck applications?
  
  The enemy of ICE efficiency is constantly changing load and engine speed. The series hybrid can avoid a lot of that, even when vehicle power demands are changing often.

  You're actually using buses and garbage trucks as an argument for small passenger vehicles. Your ability to come up with the dumbest, most insane arguments never fails to impress.
  Maybe all cars should have a jet engine. Look at how efficient that is for planes!

  We will soon see how things play out as HMG will be offering both EREVs and PHEVs, along with HEVs.
  HEVs will continue to dominate as long as they have the sizable price advantage over the other 2.
  As long as pricing are roughly similar, can see EREVs edging out PHEVs in the luxury space due to superior NVH.

  MC, absolutely none of that changes that whatever this car turns out to be, it will have that droning engine that spews fumes, requiring that you spend your hard earned time every few days going to the smelly gas station, getting gas on your pants and shoes, and then having the maintenance requirements of an ICE--time, parts, service expenses all in there.
  And when you're driving from wall power, you're wasting that wall power dragging that heavy gas engine around.
  No, we've heard all your chatter about how PHEV is bad. You can't backtrack now. This is a PHEV, and has all the "worst of both worlds" as you call it. No rearrangement of the fiddly bits changes any of that. You have zero standing to declare this product to be a "good thing".

  The important part isn't the size of the vehicle, it's how it's driven. Buses and garbage trucks spend their entire days starting and stopping. ICEs absolutely hate that. The best technology for that application is a pure EV, but if the charging speed limitations mean that an EV doesn't work, the next best choice is something that detaches the ICE from the constant starting and stopping. That's a series hybrid powertrain. A PSD is the next best thing after that.
  Pretty much the entire transit bus industry has gone hybrid and the series concept is dominant in the market (with a PSD system in second place).

My money is this will operate just like a Chevy Volt. Three modes: EV, Series Hybrid, Parallel Hybrid. If it is a true series hybrid I'd expect the fuel economy to be awful once the battery is exhausted unless there is some new tech. pioneered in it.

When first introduced, GM wanted to hide the fact that the ICE in the Volt would couple with the drive wheels under certain conditions with an exhausted battery. Not sure what the big deal was as the reason for it was simply better efficiency while in gas mode. The BMW I3 was a true series hybrid and that was an absolute disaster in rathe extending mode. Has Hyundai figured out how to make an efficient series hybrid?

  yeah, it was after seeing AutoWeek "report" on the Volt using Chevy's own PR material, hiding all of that, that I cancelled AutoWeek. I realized it had switched from actual reporting to simply re-printing PR materials from the automaker hacks.
  My money is with yours on this. Regardless, it's a PHEV with every "downside" that MC declared was the "worst of all worlds".

Andarris Here in the Toronto area I haven't seen a 2006-2012 with intact rocker pannels for over two years now. I presume everywhere around the Great Lakes is the same ? They were super cheap dhring the first two years of the pandemic - could get one with less than 85K for around $6500 certified or a little higher mileage for $5000. Glad I skipped it, even in 2021 some of the 10's &11's were displaying corosion like you'd see on a 7 year older Impala, Camry or Accord. Also the mid-model switch to EPS made me balk at the few clean ones I found.

Michael S6 The 3 Amigos better hope that the oil spike is short lived as 4-5 dollar a gallon gas would put a damper on their cash cows especially "Ford's strategic shift" of killing off the escape/Lincoln cousin. Most other automakers have a full line of vehicles with much better full economy. GM is sucking air and its Cadillac devision is mostly EV and geriatric line up of ICE cars and SUV's that were supposed to be phased out this year. The expensive gas may push shoppers toward EV but GM's horrible EV reliability is a barrier.
