Tbh, the ES is newer, has more tech and is more practical while being similarly priced to the IS. The worst thing about the IS (other than its age) is the lack of practicality inside! It has no sunglasses holder (not a biggie...I've realised the heat from the roof has actually damaged my lenses now), no random pockets to put miscellaneous goods (such as sunglasses), absolutely midget glove box...the centre console is large enough to fit only my sunglasses case. I cant stick in a tall USB stick as it wont close properly, I cant put in a box of tissues and will have to resort to having a box in the passenger footwell...yeah all minor gripes. But if I wasn't so in love with the thing, I wouldn't have gotten the car. It is majorly flawed in a practicality sense.
I mean it is nice to have a car that makes you feel special like the IS does. But some practicality wouldn't be amiss. So, apart from improvements in the engine department, looks and maybe size, interior practicality would be pretty important too I reckon.
Practicality is really the least of the car's problems - it is far behind in infotainment, powertrains, technology, luxury features and safety.
Lexus thinks IS buyers are so very different from ES buyers - and will be standing in line eager to have the latest and greatest when the new model comes out, but they are wrong. Just like with ES/GS, a lot of people are payment shoppers and looking for the "most car" at a certain price. Even ES is no longer stodgy and boring, let alone how competitors have progressed compared to IS. I think ES stands to hurt IS as much as it did the GS.
Even as someone who likes to drive aggressively, if 2020 brings ES 350 F Sport AWD, I would probably choose that over an IS 350 at this point for similar money. Many others will feel similarly considering the newer platform and tech, similar horsepower, bigger interior and better infotainment. The only reason I can think someone would purchase an IS over an ES right now is if they have to have RWD (which most shoppers don't even know the difference) or if they just prefer a smaller car.
I will not be surprised if the ES begins to cannibalize the IS, similar to the GS:
- A rapidly shrinking passenger car market means more scrutiny and competition
- ES now comes with an F Sport package and soon, AWD, for the same amount of money as IS - in a car that's much larger and now very good looking
- Competitors have fully redesigned their models - and introduced new ones - once or twice already over the 3IS lifecycle
- Mixed signals and news on powertrains makes me think this could be another lukewarm product release
I know a lot of people who have left Lexus and specifically the IS line as their leases end or they get tired of the car, and gone to BMW, Mercedes and Audi. Why? IS has barely changed over a decade. It used to be the hot rod of the entry level luxury sedan class but Lexus gave that title up long ago - it offers no standout features, functionality or personality.
The 3IS has different sheetmetal and a sharper interior, but there is no massive, wholesale evolutionary change that says "Lexus is leading" in this segment. Same V6, has-been 2.0T, lack of F model, no hybrid, lack of customization, no plug in, no diversity on F Sport models, barely even new wheel designs, etc. Those people probably aren't coming back unless Lexus comes out with something like a Macan or Stelvio.
When people leave, they get sucked into a different ecosystem with brands who offer fresh product lines and good reason to trade up every 2-3 years. Whether it's organizational change, poor product planning, both or something else, Lexus has not given people much reason to trade up over the last decade - and the sales are proof of that.
I am hoping 4IS is dramatic and unexpected... if it's not, it is probably DOA. With this market, 3er and C reign supreme and nobody is pining for a small Lexus sedan just because it's a Lexus. The car needs to come out looking something like a swept back four door coupe, 285-300hp 4-cyl base engine, 416hp F Sport model, hybrid, Android Auto, Apple CarPlay, 10.5" touchscreen standard, 12.3" touchscreen optional, multiple package options for wheels as well as internal/external colors, track packages, triple LED headlights, etc. Even if nobody who buys these cars needs a 3.5L TT V6 monster with a track handling package, let's face it... cars are going to become emotional purchases just like coupes. SUVs are what is rational and expected. If Lexus goes down that route, they're going to be in trouble.
