Has anyone noticed the gas pedal uses some new design? It appears to be a pedal interface with a wire coming out of it. The brake is still a mechanical lever going through the firewall.

I think most if not all 2003 Lexus models are throttle by wire. The brakes are still mechanical, the new MB E class I think has brake by wire too, but Car and Driver guys said it was too isolated in feel...not good for "spirited driving".

On a side note a friend of mine has a bimmer with throttle by wire and it feels ratchety...(not smooth uptake/fuel delivery) the car seems to lurch off the line no matter how gently you hit the throttle.

How long has Lexus been doing this. The GX throttle response and feel is great. My GS400(2000) was excellent too, but not sure if it has this.

I htink someone posted something about it in the GS forum a while back..I think 2000 forward has it, but 2000 also has cable backup 2001+ has no cable. Not 100% sure though/
