just curious is the G35 drive by wire or normal throttle cable??

thanks!

Hey can anyone define what drive by wire is? BK your car is off the hook

 

Drive-by-wire means it's electronically controlled. Theres no actual cable running from the gas-pedal to the engine compartment. The computer adjusts fuel flow according to how you work the gas-pedal.

I like to refer it as more like "fly by wire". This tech was taken from the military. JSYN

hmmm I wonder why this point is not advertised since it is a pretty advance feature??

 

It is advertised, both on the website and in the brochure. What is more impressive is what it is needed for- VDC. While basic traction control can be achieved without, effective stability control systems need the ability to take the throttle out of your control in milliseconds, so the computer can deal with the mess you've made.
On my second test drive in late Nov 02, the salesman took me to a quite business park on a Sunday morning. As I was setting up for what I assessed as a turn that in my old Corrado I'd have done at 90 (normal method, double the yellow warning sign speed, add 10), I began to touch the brakes to haul down from around 140. He says, "no, just mash it" (I look down to see 120). My wife takes a big breath, I think oh well, plenty of run off, rwd, we're in for a spin. I get ready to counter steer, turn in hard, throttle mashed, and.....nothing. Car goes whisper quite, brakes grab momentarily, and off we shoot the exit, all the while looking like Juan Pablo or Michael. Nope. I can't drive that well. Thank you VDC. Drive by wire, though cool, is just a component, like the accelerometers, abs sensors, and computer.
Fly by wire? check out some of the new concept cars that use a joystick instead of a steering wheel and pedals. Audi starting looking at it 5 years ago, using a pressure sensitive stationary stick a la F-16. That's fly-by-wire.

Just be careful doing that. As good as stability control systems are, they can't exceed the laws of physics. If you're going too fast into the corner and don't have enough rubber, the car's gonna keep going roughly straight no matter what the car's computer tries to do about it.

 

IMO, drive by wire sux, you can see throttle lag (lack of throttle responsiveness)

 

Ryoken, too true- note my comment ref runoff. Another of my friends wanted to see the limits of the VDC (mechanical engineer and enthusiast) but late last winter, from a standstill, in the snow, I was unable to overwhelm the system. Try as I might, with it engaged, I could not get the car to spin in an empty parking lot (long string of serpentine half moons down the lot). Deselecting the system- car spun in a blink. Then this past fall, in the rain, a different test. Accelerate to around the top of first with some drift on, then throw it hard over (we launched from a t-junction onto an empty four lane street and went to lock with the throttle pinned at the other side, making a left) We succeeded! The system was unable to stop the spin, so it slowed the spin to an almost slow-mo controllable pace, but we did get it to come around 180 degrees. This by the way delighted my friend, since he was afraid to VDC would interfere "too much". The intervention allowed me to control the vehicle, while still not negating the handling of the rwd vehicle. For the most part, the VDC will result in some (normally healthy) understeer.
Profile, doubt your perceiving lag. More likely, it's the system keeping you closer to the limits of traction rather than smoking your Pilots. Hammer on and off around 2 thirds up the rev range in say 3rd (where traction and power are closer to balanced). on warm tires. Engine responds to your foot pretty darn fast IMO.

If you feel that the drive by wire is a slow response, try some grounding wires. From what i understand, that should help with the response of the engine by grounding out all the extra frequencies.
