I agree with you there. But sometimes, cars with the same horsepower and similiar wrights end up having very different acceleration times. Other factors to consider are rear end ratio, suspension setup, transmission, etc. All these other factors can greatly change the performance of a vehicle.

lol...I will race one of those any day of the week if they think they can best my C32. C32 numbers are almost identical to the C55 (depending on what you read or who you talk to) and has been demonstrated multiple times on mbworld.org that through the 1/4 they are very close with the 55 ultimately winning at the high-end. It's very give-and-take with the M3 as well.

I would be willing to bet that the C43 would also hand the C350 is **** every single time...

I would imagine that the IS350 would also easily win against the C320 replacement. Only thing negative about the IS is the lack of a manual tranny option...

The negative about the C350 is that is costs over $50K fully loaded...basically you are in C55 territory at that price with many of the options as standard equipment but no manual tranny. For the same price you are looking at a very nicely modded IS350.

and that lovely CVT tranny in the audi's are failing...and Audi knows it and are merely having their tech's do band-aid fixes to them. Failures are occuring as early as 10k through 50k and these trannies are not cheap to replace either.

need a 1/4mi time for this thread to have any meaning
0-60 times are of little use

doesn't sound like the engine is underated in the slightest to me.
a 268hp 5spd Avalon clocked 6.0sec not too long ago.

Thanks for renaming the thread title so that we now know it's a manual. With a slightly higher horsepower and more torque, the manual C350 getting from 0 to 60mph in 0.1 sec faster than a manual 330i (tested by C&D in 5.6 secs) only makes sense. Now all that is left to know is how much faster than 5.1 secs a manual IS350 will be if one comes out.

From a friend who sells Lexus ... a colleague reported 0-60mph in 5.3sec for the IS350 (in car GPS set-up) during a ride and drive, which isn't very far off from Car & Driver's almost un-believable 5.1sec time. I didn't believe the C&D time, but now I'm thinking this car is just that fast!

ok so an automatic tranny vs a manual? and the rear end won't be THAT different, sorry... we're not dealing with american V8s that run a 2.73 or 2.59 rear end ratio here... its a typical import and is running somewhere between 3.5 and 4.5 just like all the other import 'sporty' cars.

No, it was a 280hp Avalon in a 3500lb car... and it is also rumored to be underrated. (all the newer GR motors are)

306hp in a 3500lb car doesnt equal up to 104mph trap speeds... if it did then the 98 GS400 which weighed about the same that made 300hp would be running 102ish traps... not 97-98 like it does stock.
Why? easiest explanation is that its underrated by about 25hp
or that the car weighs a good bit less than stated (which i think 3500 is right on considering the chassis is from the GS)...
or that the 6 speed auto is HELLA more efficient than for which we give it credit...

or it might be a combination of all these things
