Replying to: twq83 (Jun 10, 2007 7:25 am) Is the IS-F available as an AWD?
#130 of 147 IS-F in AWD???? by twq83 Jun 11, 2007 (11:21 am)
The best sources at Lexus say "NO" ....... it's simply a question of Performance!!!! At 400+ HP an AWD platform would be counter productive, In simpler terms it can't handle the Horses..... we'de have to tune down the Horses and that would be counter productive to the Performance aspects of the IS-F..........   Sorry, the 2008 IS 250 will still be offered as a AWD Model.

Replying to: twq83 (Jun 11, 2007 11:21 am) Tell that to Lamborghini, Porsche and Audi. They seem to put a great deal of horses into AWD just fine.

Replying to: twq83 (Jun 11, 2007 11:21 am) Sounds like a false excuse. AWD would not require reducing HP, but it would allow for increased HP. However it would somewhat increase weight and reduce gas mileage. Seems like it's really nothing more than a choice.

Replying to: michael2003 (Jun 28, 2007 3:23 am) OK Michael Before we start throwing " false excuses" as the answer to the comment let's take a Look at the cars in question. Audi R8, wonderful vehicle and AWD! imagine that Also a "Mid Engine Mount"!!!! Talk about apples and oranges The structual specifications for a Mid Engine Mounted vehicles allow for the rigidity and support need in a AWD vehicle with the accent on Performance..... OK the Lambo ........ Damn ....... another Mid Engine Mounted Vehicle. OK then onto the Porsche ...... 911?, Boxer?, Cayman ?, all have the engine in the front, all Performance vehicles ........ Oh Gosh .... NO AWD!!! Wait a minute there is the Porsche Cayenne, that's AWD ..... But it's an SUV!   So now it looks as if your choice is: do you want a "Mid Mounted Engine" and AWD or do you go for the true Performance vehicle and stick with the rear wheel drive. Anybody care to discuss Apples to Apples????   Just my $0.02........

Replying to: twq83 (Jun 28, 2007 6:30 am) Uh...few corrections   1. 911 is rear engine mount 2. Boxster & Cayman are mid engine mount 3. Porsche does offer an AWD 911 version. Targa(?) Replies to this message: twq83 (Jun 28, 2007 7:00 am) louiswei (Jun 28, 2007 7:08 am)

Replying to: louiswei (Jun 28, 2007 6:49 am) Again, My point exactly ... Mid-Engine Mount, REAR-Engine Mount both are significatly structured differently to allow for the AWD possibility! Yes or No? Replies to this message: louiswei (Jun 28, 2007 7:08 am)

Replying to: twq83 (Jun 28, 2007 7:00 am) I don't see how more difficult that a front-engine-mount car to allow AWD than a rear-engine-mount one. But anyway, the point should be that the IS-F DOES NOT need to be AWD, period. Why? I'll give you several whys...   1. M3 isn't AWD 2. C63 AMG won't be AWD 3. The only reason why the RS4 is AWD is because Audi is specialized in AWD and they don't have a dedicated RWD platform.

Replying to: twq83 (Jun 28, 2007 6:30 am) My reason for saying that an AWD system would require reducing HP is a 'False Excuse' is that putting AWD would actually allow much greater HP since a 2WD system has limits on how much traction can actually get to the road, so the statement just doesn't seem to make any sense. Please note that I'm also only talking about street legal vehicles used for transportation.   Adding an AWD system that only puts a small percentage of the traction to the front wheels still allows that much of a percentage of additional HP to be available towards getting traction.

Replying to: michael2003 (Jun 29, 2007 2:03 am) Michael,   Adding HP is just a matter of adding a larger more efficent Engine! What your talking about with traction addition is Torque ( the force that get's the vehicle moving)and this requires Structural and Pitch and roll supports to ensure that the vehicle doesn't tear itself apart over the years. The more weight you add the less Torque you can produce...... hence the less PERFORMANCE the vehicle is allowed to exert on you and your driving experience. AWD adds stability and some Torque at the expense of performance. SEE???
