I am on the board as well but did not get that survey. Maybe they send it at different times. I am not against a turbo 4 in the IS250. I've driven a few T4 cars and they are faster than my 250. I don't have problems with the power in my car right now. If I get the survey I will certainly tell them I don't care what they put in it but it better wow the hell out of me if it is a 4 banger.

Lets see, the number of 4 bangers I had in my life
'74 Opal Manta(1800cc), '76 Fiat 124 (1800cc), '79 Corolla (1600cc), '80 Challenger (2600cc), '88 Conquest (2600CC Turbo), '80 Mustang (2300cc), '91 Galant VR4 (2000cc), '89 Subaru XT (1800cc), '05 Audi A4 (2000cc Turbo).

I obviously have no problem with 4 cylinders, and feel those complaining about "roughness" have had very little experience with the more modern ones. Mitsubishi uses counter rotating balance shafts to virtually eliminate engine vibration (a design later licensed to Porsche)
As you can take a Mitsu 2.0l quite close to the 400hp range with amazing reliability, I would challenge Lex to step up to the plate with something nearly as well built and capable.
The Subaru was also a sweet and smooth motor with the opposed cylinder design.
Of all of them, I'd say the Ford 2300, and the Audi A4 were the two worst built 4's Ive had so far.

I am older now, and prefer the 6 cylinder for the ability to strain less on the simple tasks and still provide good MPG, but I wont run from a 4 cylinder in the future if it is done right...

I think they were asking you about engines regarding the next IS250, and I guarantee they have the 350 variant already decided. I'd imagine it's gonna be a 3.5L, 3.7L or 3.8L with 330-350 HP.

Dropping a 4cyl turbo into the IS250 wouldn't be bad at all. The Current 6cyl engine is like a fake 6 cyl anyway. They can EASILY get 250hp out of a 4cyl turbo DI motor.

I wish they'd offer a true manual transmission. 6spd preferably but I'd take a 5spd. I guess it doesn't matter though, My next car won't be an IS no matter what they offer...

I have driven a passat (that I had as a rental for several months while my car was in the body shop) it had the 2.0T 4 cylinder and I didn't care much for it either. I just don't think I can be persuaded to pay 38K + for a 4.

IMO I think Lexus should take the same direction as the MBZ C-Class: C250, C300, and C350. The I-4 w/ less power/more mpg, and the two V6s sporting the best of both worlds and more power/less mpg formula.

My list of 4 cylinders is pretty long, and ends with a counter-balanced 2009 Corolla XRS. I also still have my 86 Corolla GT-S with 4A-GZE swap. I have no problem with them at all, they just don't scream Lexus to me.

There is no C250 right now (in US AFAIK)

We don't need 3 versions. Why would anyone need the middle one? We just need a lower and higher one. Just like everything else:

BMW 328/335
TSX 4cyl/6cyl
Infiniti G25/G35
MB C300/C350
Audi A4 4cyl/6cyl

For the driver sensitive to both issues.

C250 is a 2012 model and is slated for release in the U.S.

Mercedes-Benz is offering an all-new four-cylinder engine option here in the United States (as well as a new model designation – C250)

Default 2,4,6,8 what do we appreciate

I loved my inline 6 in my IS300 and GS300. A little disappointed to see the V in my new IS250, but had to move on. That being said, one of the charms of the first IS was that it was really tuner edgy with the tail lights and rabbit skin seats. It might be exciting to see a 4 cylinder turbo tuner IS that could really tear up the road and be easily modified as well. Lotus uses a 4 cylinder Toyota engine - when I think of Lotus, I think high end performance.

I highly doubt Lexus would drop hp and performance on the upcoming models. These surveys are usually all over the board.

I also did not receive this survey. My only four was a Porsche, an '85 944. Since it was half a V8, it was actually a pretty good slant four in it's day. I also had an SC300 5MT. The only straight six left in production is, I believe, BMWs. As you can tell from my family's automobile's, we like multi cylinders

My 4 cylinder was an 87 944 Loved it but it could wear out some motor mounts!

Ok I knew there wasn't one right now. But they're gonna keep the C300 too? WTF do we need 4 engines in the same chassis for? I bet they drop the C300.

No 4cyl in the IS unless it's 3.0-4.0 liters with a turbo hanging off of it. That should be standard with a V6 (or 2) as an option as with the Genesis Coupe offering.

I would prefer a NA 3.X V8 in my dream IS.
