It will be interesting to see how much of a come back the i6 makes and whether the i3 quad turbo is abandoned. Wonder if we'll see more hybrid i6's.
This is news to me! I thought he 2021 IS is using the old 3.5L V6!
The only reason the Toyota Supra is using bmw’s engine is because Toyota funded the z4/Supra platform and it’s a dedicated platform. I see no reason why bmw would let Toyota/Lexus use their engine for anything else.

Who'd have thought naturally aspirated performance cars would be the hill Lexus would decide to die on.

Gosh darn it. A Lexus with an i6 might have been quite good.

Unfortunately, this seems like the trend we're going with, but I'm definitely not on board. There's far more to me than just pure hp and torque. Not counting fuel efficiency, I'd gladly pick my US spec S52 with only 240 hp and 240 ft/lbs over a turbocharged 4 cylinder which will have that amount plus plenty of tuning potential. Things like engine smoothness, character, sound and even maintenance matter far more to me.

Personally, I'd rather just go electric than having a 4 pot.

Toyota/Lexus has partnership with Mazda and is funding their development of their inline6. They plan to use that motor in next IS which will be few years from now.

The 2021 IS is just a heavy refresh.

I'm glad my vehicles are still I-6 and V8 but as soon as someone figures out a way to tow 8000 pounds continuously for 300+ miles with an electric vehicle and be able to charge it in 10 minutes or less those cylinders will be gone too.

Imagine the future W224 Mercedes S-Class with four cylinder engines only, or electric.

The balance shaft will be *really* good in this imagined W224.

I test drove a new C220d today and it pulled like a freight train. The tech is definitely there but I question the longevity of these engines albeit they are cheaper to produce. Very impressed with it. Felt stronger than a 320d. With manufacturers squeezing every last drop of power and providing i6 characteristics in an i4 it makes me wonder which way things are headed. Interesting times.

Agree with comments on electric and towing.

not a fan of most of these modern engines with laggy turbos and redlines below 8k for a weekend ride. its fine for a daily use since you can be in the meaty part of the powerband while cruising and don't need to shift. but when i'm hitting corners i don't want to wait for a turbo to spool up.

that's why my m3 will continue to be daily, and why im skipping over the 488/720/570s in favor of a 9000rpm gt3 for my weekend ride right now.

If you are getting lag on a turbo that provides full torque at 1500...you are doing it wrong.

What you are most likely experiencing is the transmission shifting down 2 or more gears in response to you flooring the throttle at low RPM. If it's a DCT, it probably only has the next lowest gear selected and whether it's a slush box or DCT, it's going to get a little confused and have to shift down a few gears, unless you were already running relatively high RPM, which is unlikely unless you are driving around in manual paddle-shift mode all the time. If you were say at 2000 and held it in gear, it's going to pull just fine, not as good as at 4K with all the HP to back it up, but it's still going to make massive torque and pull out of a hole. That and the throttle mapping due to the mode you are in. People thinking that turbos tapping directly off of the block with small twin-scrolls are "lagging" like old 930 where you had to get up to 4K before the thing would make any torque are mistaken.

mine is a manual. i'm taking about going through tight twisty sections of road and being on and off throttle as you navigate the turns. or even just doing pulls in second gear. you hit the throttle have to wait a split second, and then the wheels start spinning. its not instantaneous like my old 458 or buddies viper.

I think Lexus has given up trying to compete directly with the Germans. The killing of the GS tells me that.

But the IS with a straight six might be a good cruiser which is more of the target audience for Lexus. Lexus sells enough cars, at least in the US, that it doesn't need to compete directly with the Germans; it has its own very profitable place.

No, they're sticking with 4's, 6's and 8's with various power set ups.

And in my last two turbo cars (well, I have another now) the turbo is spinning all the time, response around 1500 or more is pretty much instant, my big V8 engine lugs just as much, if not more, when you hit the gas down low where it has enough torque, but it doesn't have the HP. So it'll climb, but you don't go shooting off like a rocket like you do at 5000rpm...and that's naturally aspirated. Do you get the same response in sport and sport+? If so, ok, but if not, it's throttle mapping and not the turbo.
