Here is the technical definition, if it helps:
 
P0441....Evaporative Emission Control System Incorrect Purge Flow
 
P0455....Evaporative Emission Control System Leak Detected (gross leak)
 
Any one who understands the tech side of this is welcome to explain it to everybody.... but it really doesn't sound that complicated if you repair cars and sure doesn't look like $600...

Hi everyone
 
Just curious, so we worked out the top end is probably about 140mph on this car.
Just curious how the heavy VW R32 with a far less powerful 3.2 L motor claims they limited the top end to 155mph if the more powerful Avalon motor could not even reach this.
 
Is this claim of 155mph on a standard 3.2L V6 with no form of turbo realistic? as I was thinking it would be a weight vs horsepower scenario to see how far the motor could get the chunk of metal.
 
The weight from what I read for both cars is about 3500 lbs, so weight is near equal.
Power on the avalon is claimed at 168bhp 6200 with the VW claiming 250bhp 6300
Torque for the avalon is claimed to be 248 lb.-ft. 4700 rpm where the VW is claimed at 236 2,500-3,000
 
So if you have a car that is pushing a fair amount less power+torque at about the same weight, how is it possible with aerodynamics that I dont think could account for a limited 155mph let alone anything over that?
 
Just curious for the more technical folk here.
 
Thanks and happy holidays everyone!!

Sheldon, FYI...
 
The weight of a vehicle has very little to do with vehicle top speed, whatever it is. Reason: "Objects in motion tend to stay in motion...."
 
The weight of a vehicle has everything to do with how long it takes to acheive top speed from rest. Reason: "Objects at rest tend to stay at rest...."
 
For top speed limitations the single biggest factor is air, also known as aerodynamic drag (Cd). A smaller engine of less power can easily propel a different vehicle to a higher top speed if the body of the second vehicle is more aerodynamic. Physics 102...
 
Enjoy an Avalon today... Great Cars..

Yes, a lower Cd means a vehicle will not disturb as much air and will be more efficient at high speed, all else remaining equal. Also, there is little difference up to about, say, 45 mph due to the basic design of the car itself. After that, Cd becomes more important very rapidly as frontal air pressure increases with the square of the speed...
