Why would you assume it would be that dramatically off?

Even if it were, it will still feel quicker due to the power and of this style of engine.

 

Because seeing is believing. Things change and they very easily could have overestimated. In my profession, I deal in absolutes whenever I can.

It doesn't matter, I'm speaking hypothetically.

What if.

Would it change your mind if this engine pushed lower speeds? That's the only measuring stick this engine has versus the competition so what if it was weaker than anticipated?

 

What if it runs on lemonade and exhausts rainbows? Speaking in hypotheticals makes no sense. Of course we would be disappointed if it underperformed their estimates dramatically, but there's no rational reason to expect that it will.

The competition doesn't bother me very much. My LS is dramatically slower than the competition and I still chose it. (So is yours since they're the same car)

Not sure why you seem to take this engines use so personally.

 

Sure it does. What ifs are an important part of life. You make decisions without thinking about various scenarios?

If so, god bless.

Call me skeptical, but until I see it validated I'll believe it then. Some people will gladly stand around and let people **** on them while they whisper it's just raining all day long. Not me.

 

All fair points. But what must be remembered is that much of this comes from two main sources....first, the government demanding more and more safety-equipment, and typical consumers demanding more and more comfort/convienence items. It's also a reason why even some econoboxes often weigh more than 3000 lbs. nowadays.

 

Seeing that none of us can purchase an LS500 even if we wanted to, this isn't a decision that any of us can make so why spend time thinking about a bunch of different scenarios? It's like saying "yeah they say it has all of these technologies to make it quieter, but what if it's louder?" You have no reason to think that will be the case, and in any event what's the sense in discussing it until somebody has driven the car?

but no, the 0-60 time wouldn't impact my decision to purchase at all. What matters to me is how the power train and the acceleration feels when actually driving the car.

 

Most of the general buying public is that way (including you and me). But manufacturers tend to listen to the auto press and the enthusiast magazines, of which the vast majority are strongly sport-oriented. The Lincoln Continental and Genesis G90, though, are a couple of signs that they may (?) be easing up some, though, on that sport-sedan orientation. I'll withhold more comment on the LS500 until I see and/or drive it.

 

No, not at all. You'll be hard pressed to feel any difference between 4.5 vs 5.5 second 0-60. I'm a lot more interested in how the car responds to the throttle. I would like it have eco, comfort and sport modes, preferably where each mode lets you adjust throttle, steering, transmission and suspension independent of each other.

 

you can't be serious. that's a huge difference and anyone who is remotely into driving can feel that.

 

i agree with this. if today i am getting a amg or m car, i would care. but on a car like LS (or s class for that matter), i care more about how the power is being delivered. and that's exactly my worry given my experience with cars like gls450/550. not saying lexus can't do it with the v6tt but i have my doubts, especially on the overall smoothness and drivetrain effort

 

Generally 0-60 times are a benchmark which, if they are favorable, become advertising fodder. That's why manufacturers use them in ad copy. For this demographic of buyers, I doubt anybody worries too much about this car being off by half a second or fractions of a second here and there. Those 0-60 and quarter mile times are under ideal test conditions. In the real world they will vary and even change from test to test depending on atmospheric conditions, individual drivers and which test track a drive or review is being conducted.

But to the point, yes if you want to ask for this kind of money from potential buyers, you will have to make sure your car meets its performance benchmarks in the real world, which Lexus of course has verified through a lot of testing. Some days the car could be faster than 4.5 seconds to 60 mph and other days it may take 5 seconds. It would not be unusual for an LS to not meet the advertised time though.

Car and Driver's test of the then new LS460 in 2007:

Depending on a car too. A smaller, lighter, less isolated car that is lower to the ground can feel faster than a large, isolated one.

 

Och, congrats on the M! When you will receive it? Have fun with it and make sure to tune it

 

Yeah there's a huge difference in feel between 0-60 in 6 seconds versus 5.4 seconds, which is the claimed time differences between my last and current car.

Also most car writers at established magazines can verify it. I know conditions can have a slight impact, but with these modern cars with automatics and traction or even launch control, if a manufacturer says something, it wouldn't be hard to prove.

The issue here is that we can't prove it yet. Production versions could be slightly different or they could be exaggerating. Say they have to redo the exhaust in the production for whatever reason.

The point I was making is that their whole claim that this V6 equals the competitions V8 is based on that claimed time. Well if doesn't past muster then I guess that claim isn't accurate.

 

I would venture to say the difference between the 6 seconds and 5.4 seconds you feel is not the .6 second, it's the gearing and power bands of the two power trains. It's entirely possible you'd feel the same benefits even if that time difference wasn't there.

You're not out driving around at WOT all the time.
