IS 350 vs GS 450h...could we win?
#31
This disagrees with all published performance I've ever seen on the cars.
The GS is very heavy... 1/4 mile times are in the 13.5-14 second range... the IS350 is in the 13.2-13.5 range.
That's up to north of 100 mph for a 1/4 mile run, with the IS350 getting there first.
Now, much north of 100-110 might be another story, especially given the way the IS is geared...... but no way a GSH is pulling away at 45, he'd be behind the IS350 at that point.

Let's look at 2 different sites for each car just to be fair
Lexus.com
Lexus IS350- 0-60 in 5.6 seconds
Lexus GS450h- 0-60 in 5.2 seconds
Inside Line
Lexus IS350 *just for fun the Bimmer BMW 335i Sedan
0-45 in 3.4 0-45 in 3.2
0-60 in 5.2 0-60 in 4.9
0-75 in 7.7 0-75 in 7.2
1/4 mile in 13.8 @ 101.2 1/4 mile in 13.4 @ 103.9
Lexus GS450h
0-45 in 3.8
0-60 in 5.6
0-75 in 7.9
1/4 mile in 13.68 @ 104.23
I'm sure you can look all over the web and find some different numbers depending on the weather, condition of the car, and the driver.
With the exception of 1 test performed by Road and Track in 2007, all of the IS350 times posted on the web ranged between 5.1 - 6.0 sec 0-60.
All the sites I saw for the GS450h had times ranging from 5.1 - 5.6 sec 0-60. Regardless of the 0-60 time, EVERY SINGLE TEST had the IS350 with a lower trap speed than the GS450h. The GS450h averages about 103 - 105 mph trap speed. That being said, from a dead stop, Yes, the IS350 could take a small lead initially if launched properly. It seems like no matter who is driving the GS-h it still continually pulls low 5's all day long.
So I'm not sure why you have such a hard time believing that a GS-h can win against an IS350-****ESPECIALLY FROM A ROLL****!
The GS-h lacks in initial take-off because the traction control limits the wheelspin and wont allow a hard launch. After that the car turns into a beast and relentlessly pulls with seamless effort thanks to the CVT auto tranny. Once the GS-h gets rolling (even from 20 mph onward), the IS350 really doesn't have much of a chance. If Lexus could figure out how to get the power to the ground in the GS-h from a dead stop, the GS-h would probably be 0-60 in about 4.5 seconds with a hard launch.
Don't let the HP numbers fool you. The GS-h's V6 is rated at 292HP and the electric motor puts out another 194HP. Lexus claims the total output of the motor combined is 340HP even though those 2 numbers add up to 486HP, and the power curve is pretty flat. The torque is available immediately and it never falls off.
I'm sure you're quite familiar with the BMW 335i sedan seeing as it was pretty much built to contend with the IS350. I've beaten both the sedan and coupe versions of the 335i. I beat the coupe from a 60 mph roll and I beat the sedan from a 40 mph roll.
If you're ever in the Tucson area please give me a shout.
Take care.

Do a search on dragtimes, you'll find IS350 after IS350, stock, running under 13.5, all over 100 mph.

The top 13 results are all IS350s
The dragtimes results show exactly that comparing these two cars.
The GS450h being so rather heavy is one good cause.
It's lighter, and geared to be very quick to 100 mph.
But I never said if both cars race from 60 to 140 that the GS won't win. I said that in 0-60 and 1/4 mile the GS won't win. And all the real world results I've posted show that.
Given how insanely more expensive the GS450h is I'd sure hope it CAN win at something

And given the GS450H is priced like an IS-F that seems like the better comparison... where the F crushes it.
The fact the IS350 is likely a touch faster up to 100 or so (and even you seem to agree it's at least close) yet costs only 2/3rds as much, is a pretty decent accomplishment in its own right.

Ha Ha, my computer keyboard is faster than your computer keyboard. Have either of you guys ever actually taken your cars to the dragstrip?
I have lots of experience and as was stated, much depends on weather/track conditions.

Here is my IS350 running 13.1@104.44 with exhaust, intake, and heavy 19 inch wheels.
http://www.dragtimes.com/Lexus-IS350...lip-21998.html
From 0, there is no way a stock GS450H can keep up in a quarter mile with a stock IS350.

I didn't even bother posting numbers from dragtimes.com because there's no way of knowing how accurate they are. Some hillbilly in Arkansas could've been running slicks on a track with faulty equipment and then turn around and post that he ran a fast time in "stock" trim. In any event, the argument is not that the IS350 isn't capable of beating the GS450h, but rather that it is very possible for a GSh to beat an IS350 depending on the circumstances. From a roll, you can forget about it though.
You can turn off the traction control but for some reason it keeps wanting to intervene when you try to launch the GS. I'm not sure if its set up differently than the IS or what. Maybe it's a less aggressive setting, I'm not sure.
I'll be the first to admit that the IS will carve the GS up pretty badly in corners. The IS was designed to be an entry-level compact sports car, the GS is a mid-size executive sports sedan. Both cars have their unique qualities. I'd personally like to have an IS and a GS to suit my needs depending on my mood. The IS-F would be great for some of the twisty mountain roads outside of Tucson.
As I stated previously, I'm not sure, could be a different setup?
At the end of the day it boils down to the driver of the car.
If anyone wants to test this theory, please feel free to hit me up next time you're in southern AZ.

I agree with you again. But there is a difference between someone taking a home-made video posting that they ran a 4.72 0-60, and an expert driver in controlled conditions repeatedly testing a vehicle with expensive, more accurate software. I could brag and tell you that I ran a 4.6 second 0-60 with my Beltronics Vector Accelerometer but that's not a TRUE measure of what my car's 0-60 is. Besides, that doesn't take changes in elevation into consideration. It's pretty unrealistic to state that you ran 0-60 a full second quicker than the manufacturer claims. If that's the case, what would be the point of getting an IS-F which has a 0-60 in +/- 4.3 seconds if you can get an IS350 that can run a 0-60 in 4.7 seconds? Wouldn't Lexus be competing with themselves if that were true? I didn't realize the extra 33% bump in HP only shaved less than 1/2 a second off the 0-60.
You make it seem like IS-F is head to head with IS350 to 60 when they are .4 seconds apart. You need to understand that ~.5 seconds is a lot when it comes to drag racing. It could be car lengths if not bus lengths.
Comparing an IS-F to a GS450h would not be a "better comparison". The GS is a bigger car designed with a different purpose altogether. Put 2 kids in the back of the IS-F and take a 1500 mile road trip, then take the same trip in the GSh and tell me which one you'd prefer. These 2 cars are in different categories.
At the end of the day it boils down to the driver of the car.

From 0-100 I seriously doubt the H can keep up. But on a roll I will admit loss since the IS350 is not a good "roll" car.

+1
If a few different people on dragtimes run around the same times stock then why would it be a bogus timeslip? There isn't much performance modifications you can do on the IS350.
Why wouldn't it be true? There has been testings that the Vectors are within 50-100 milliseconds accurate.

I agree with you on that. But they are 2 different cars. I really don't think people who buy IS would even have a family to begin with. It is aimed towards the younger crowd while the GS is aimed toward the older crowd. I truly only used my back seats for people probably a handful of times.
+1 on the driver. The magazine have expert drivers but they might not be familiar with the car like we are. The first time I went to the drag strip I ran a 13.9-14s with traction control on. The second time I ran a 13.4 and the third time I ran a 13.1 with traction control off. They were all around the same weather (approx +/- 5F) and same track. It takes practice to launch the IS350.

I've raced a my homies is350 with my 07 GSh and run that **** all the time we meet up and ride around, info on my GS is that it's stock and fully loaded with nav, mark Levinson system, pre-collision system with radar cruise control, parking sensors, rear sunshade, and the ultra rare apsss.
You can turn off traction control the same way I did in my 07 is250, only difference is if you hold it in my IS you can turn off traction and vsc and it will stay off, the GSh will only momentarily turn off after a launch.
The reason my car beat my homies is350 is the fact that most people probably don't keep the InternalCombustionEngine on before a run on a GSh and have to wait a second before the turns back on the engine from a stop and accelerate.
If you hold the gas petal to the floor and keep your foot on the brake then you will keep the InternalCombustionEngine on before the race and will have a second faster reaction time, they say if you have the battery charged it's better but in my experience it doesn't change acceleration. I have lightweight rims and sticky tires so that helps alot but I have yet to lose a race either and I live in South Seattle where we running down MLK all day 😂
