Can someone post a definitive list of what changes when you select 'Sport' mode? I know that the shift pattern is more aggressive, the throttle seems to respond quicker, and the traction control is dialed back. Anything else? Is suspension affected in any way? :confused:

Nope the suspension does not change. The VSC does let you swing the car around more before stepping in to help keep the shiny side up.:D

Lexus ---shift modes

Can someone post a definitive list of what changes when you select 'Sport' mode? I know that the shift pattern is more aggressive, the throttle seems to respond quicker, and the traction control is dialed back. Anything else? Is suspension affected in any way? :confused:
The following info is quoted from motive magazine...

Unlike the somewhat predictable engine mods, the reprogramming of the LS's eight-speed automatic is unexpected and groundbreaking. The so-called 8-speed Sport Direct Shift gearbox has two modes: In D, the torque converter is engaged throughout all gear changes to smooth them out (and sap power and time), just as in a conventional automatic. But in manual M mode - controlled by either the gear lever or two blade-like paddles attached to the steering wheel - the converter only twists in first gear, multiplying torque for a fast launch; in gears two through eight the gearbox functions like a two-pedal manual, the torque converter's lock-up clutch providing a direct connection between throttle input and rear-wheel power. In this mode, the IS-F is the fastest-shifting manumatic on the road. It swaps cogs in 0.1 sec, faster than the F1 gearbox in the Ferrari F430, without much bucking or torque interruption - the thing even blips the throttle on downshifts. The ratios between gears three and eight are incredibly tightly spaced and short - to the extent that you question why, in a car with 371 lb-ft of flat torque, you should run through the middle ratios so quickly - but it's the small, stiff gears in this transmission that make such lightning-quick, unmassaged shifts possible. (Also, the Mercedes gearbox only has seven speeds.)

Lexus didn't neglect the IS chassis either, even if the changes here aren't as extensive as those implemented by the F's German competition. The front A-arm suspension has 90 percent stiffer springs and shocks than the IS350, with revised geometry to help mitigate brake dive. In back, the damping and springing rates are up 50 percent, but the rear toe-link bushings are more compliant than the 350's for better toe variation when cornering. Huge 14.2-inch drilled and vented Brembos with six pistons sit under the front wheels, with two-piston 13.6-inchers under the rears.




The sensors in those brakes enable a wide range of functions, bundled together in what Lexus calls Vehicle Dynamics Integrated Management (VDIM), which has three modes.
1. Normal keeps traction- and stability-control on at all times.
2. Sport ups the heft of the electronic power steering, raises transmission shift points, speeds throttle response, and relaxes the linear and lateral slip thresholds of the traction and stability systems.
3. You can also turn the whole thing off - press the button with the sliding car icon once to kill traction control, hold it down for three seconds to snuff out stability control. In all modes, ABS and the electronically controlled brake LSD are always engaged.

now is this sport mode actually make the car faster, or is it like BMW which makes the car FEEL faster without making it actually faster. just more throttle sensitive. in the m3 with WOT with/without sportmode makes no diff.

What is the matter with you? Quoting magazines regarding performance....according to some people in here you actually have to drive to know what you're talking about! Oh, this just in...new AMG 63 traps higher and is a couple tenths faster to sixty than the IS F....and is "way faster" as a result!!!! What a joke!

"way" faster is all subjective.

the C63 AMG is faster. a buddy of mine has one, whereas another friend of mine has an ISF. 40-120 runs the C63 came out ahead by about 2 cars. maybe 2 1/2.

now does that qualify for WAY faster? maybe to some, not to others. faster yes. way? well ill let you be the judge.

it is FASTER tho. thats for sure. both in the 0-60 and the 1/4. but think about it, its also 15k more...


and if they are saying that toyota is going to do a TRD S/C for 6k like on the other thread, id much rather have a FASTER lexus, with warranty, with money to spare for gas+tires.

The notion of a car being way faster is subjective and is different to one person to the next. If you go by the two fastest 0 to 60 times published (I've seen) 4.1 for the C63 and 4.3 for the IS F, a couple tenths in my estimation is not way faster. I'm guessing 99% of anyone asked feels the same way. Some idiots in here think auto reviews from reputable publications are nothing more than conjecture at best and rely on first hand driving experiences. I will play along. I was in LA two months ago and I raced a C63 stop light to light and I beat him off the line and he smoked his tires and couldn't hook...I beat him. Is the IS F faster? Based on this logic yes. I'm not using magazine articles but first hand driving experience. I am splitting hairs here but my point is made. The best way to come to a logicle and prudent determination is to use all the information at your disposal and to include the variables like driving prowess, climate, 93 octane vs 91, and the possibility that two of the same model cars could result in fractional differences in performance numbers. Oh, my IS F is faster than the C63 in LA, on that day vs that driver...maybe I should write an article

Actually I agree with WP1234 and Thecatch83 everything is a factor..I mean Yeah If the Car A is faster to begin with than Car B, it makes a difference however Everything overall factors in..
As for Sport Mode issue I do drive with it "On" and combination of using Paddle shifters makes it feel like this car is on Lighting..
I'm just blowing away cars off the road like they're nothing..
I hope TRD does the SuperCharger with Warranty tag on it..I can't even Imagine how much more Torque and Hp on this monstrous Lexus will have that 0-60 just blows out of water..Either way I got $6k waiting hoping that it is $6k..

Just a complete guess, but I'm preparing for the supercharger to cost at least $10k with dealer installation. Hope I'm wrong, though!

Anyone heard anything more on the TRD supercharger??? I'm extremely interested in any info that may be available. Tks.

once again, its possible for the slower car to win. but, if you have identical drivers in identical conditions, the C63 will win 100 pecent of the time.

thats assuming you have someone compitent behind the wheel of bot cars, with the equivilent compitency.

if someone cant launch a c63 without spinning the tires, then they most likely cannot launch the isf either. now if you are going from a roll where off the line traction is not an issue, the c63 will win everytime guaranteed. its just a faster car. period. more HP, more torque, slightly heavier but when u divide HP/weight, its simply faster.

back to the TRD supercharger, even for 10k thats a bargain. think about it. the m3 and c63 are both 10-15k more than the isf. with that S/C unit, you will make more power than both those cars, have lexus reliability and toyota warranty, and still come out around even in price.

i mean, i expect a conservative S/C unit to make power in the mid 500s crank. if they do, the only real competitor in this car's price range is going to be the new 09 CtS-V rated at 550/550 with the detuned ZR1 motor and the factory LSD. but then, when u are talking about interior quality build quality and ride quality, you cant compare. Lexus wins by a country mile.

i had an 04 CTS-V and that car went through 4 rear ends before dealerbuyback via the california lemon law. i hear the new cts-v is going to be more reliable, but from that i am very hesistant to purchase another cadillac, or any GM product for that matter.

Whew..$10K..Wow!!! As for Cadillac, it's odd that you had a problem with them! My old man drives a 02 Deville and yeah it's got problems but nothing major..I guess every car maker has lemon here or two..

normal cadillacs are pretty much problem free, but when u put a vette motor in a ctsv, basically, when you start getting up there in terms of power/torque, you better modifiy the rest of the car to be able to handle it, and problems will arise.

Ironic, that you mention engine swap..My buddy has a 95 Civic which he about to drop a K20 2006 Civic Engine into the 95 Civic..Whopping $4k for the job..

I'll stick with my IS-F with TRD SC..Whenever or if it does come out..Utilize that for a while till I figure out what I want to buy next for automobile..

well with any car, more power means greater risk to reliability.

thats just fact. however, with lexus' reputation, i am simply hoping they have spent more R&D to figure out a way to boost as much power, or close to equal power of their german rivals, but with more reliability.

you will never get a truely super reliable yet super fast car. like you wont get a fast car thats also great on gas, but you can get something thats relatively fast, while more reliable than its counterparts and better on gas as well, and im hoping lexus has achieved this with the ISF.

S/C kit even for 10k is reasonable.
heck, the S/C kit for my e46m3 STARTS at around 10k. thats without warranty. dinan's kit parts alonw is 20,000 for everything. thats not including install. the price you pay to get a S/C kit that has a warranty. its basically twice as much as competitors kits and makes slightly less power. so for 10k even parts alone with a warranty? thats a deal, and if its 10k installed? thats a freaking steal.

Oh man, $10K is pretty scary number for me to spend..It's not the money issue I don't have rather it's sum of it, that scares me..Yeah, I agree with you that Warranty offered with installation is a bargain with Super High Performance..Kinda like Before I was responding to this post I was checking out Mercedes and any one of them equipped with AMG package, instantly price just sky rockets..I mean the price difference is so huge that it's whopping..My Buddy with the CLS55 AMG he paid a hefty amount for that car..Don't get me wrong, the performance is out of this world but in order to get that reliability he definitely paid it..$100K..Whew..:eek:

put it this way. a C63 AMG new is 15k more than this car. then u go up to an E63 AMG? now youre talking 30-40k more.

how bout power? well theres nothing out for a C63, and E63 only has basic minor mods i think the package for like 20HP is around 1500.

lets take a look at an E55 AMG. benz older model. call renntech or kleeman and ask them what their stage 5 costs. bet its about 20k just for parts.

same goes for the M3. E46 M3 Dinan S/C was 19k
how bout the E60M5? a stroker kit that pumps u from 500 hp to mid 600s? is gonna run you close to 40k in parts alone, and you have to give them back your motor. thats just parts. if you want a warrantied unit.

I'm not rich like quite a few people on this site but I live "comfortable". I love my "F" and SC430. I would love to add a S/C to the "F" but for 10k that's alot of $, realisticlly priced, but just alot $. I'll have the Double Cheeseburger,no pickle,instead of the Big-Mac on the dollar menu. LOL
