Like it or not, it is going to run circles around 330i, which was already proven slow against A4 and C350 in germany - in fact, it was even slower on track than C350 !!!

And as far as me 'liking it or not', the only stake I have in this battle is getting the best car for me. If the Lexus is better than the BMW, great. If not, oh well. No dirt off my shoulder.

It makes pefect sense given the weight of the IS350 is reported by Lexus to be around 3,525 lbs which isnt exactly light for this size car. It weighs in about the same as a GS430. For the IS250 the claim upper 7 second range and lower 8 second range for the AWD. Weight for those cars are 3,450 and 3,650. These IS's are kind of heavy.
Plus, do not forget that significant underbody aerodynamic work was done to the new IS ... it's probably more aerodynamic underneath than even the new GS. Coupled with practically the same drag coefficient as the new GS (0.27), the same 6 speed tranny, and less weight than the GS430, I realistically can see the IS350 hitting 0 - 60 in about 5.5 - 5.2 sec. Who knows, the 5.0 sec flat thing, although sounding outlandish, could actually prove to be true
The IS350 will probably run to 60 in about the same time as the GS430. It weighs 200 pounds less, but also has 45 less torque.
It should definitely be the fastest among auto cars in its class, and about equal to the manual 330i and G35 6MT.

BTW, lets get back to the topic of the IS HP, not the SC. I might even split this thread and put the SC posts in car chat.

Anyway, I look forward to test driving the new IS. I'm surprised how wide the gap is between 250 and 350, and that 250 doesn't match the 325 (at least on paper). For many consumers it won't matter - it looks so much better than the cousin ES; Lexus should sell them really well - it's definitely on a roll. It may not eat much into 325 sales, but should definitely impact the sales of MB, Acura, Infiniti, and maybe Volvo.
By the way, BMW is among the top firms that MBA graduates want to work for - there's some cool factor with that company that others surely envy.

IS350 compared to 330i
+ 2.1% more weight
+ 27.2% more torque
+ 25.4% more hp.
At speed, it should run circles around 330i, even more so than what C350 did in that German test. I think ze germans summed it up quite nicely - 330i's engine is good for tests, but slow at real life from below 4,500 rpm.
Dont get me wrong, 90% of people wont even care about the differences BUT everyone makes an great deal about how 530i's engine is "much stronger" with only 10hp more than GS300's, and M45's that is much faster than GS430 (which non of the tests have shown - at speed, only 0.1 sec difference) even though torque is only slightly up - if we apply same kind of reasoning with IS350 vs 330i, then 330i is one slow car and IS350 is an Ferrari.

For the record, the fastest that the M45 has been clocked to 60 is 5.3s and the GS430's fastest time is 5.7s (R&T comparo).

If they make VDIM less intrusive than the one in the GS430, or at least give the driver the ability to shut it off or tone it down, I might just spring for one.
