[citation][nom]AlexTheBlue[/nom]The Prius uses a CVT, not a traditional automatic. There are no gears for it to hunt for. If it accelerates past the speed he sets the cruise to, there is a problem. Now, it may only be a problem with HIS Prius, e.g. a bad component. But do a little research before you blame low torque and hunting gears. I don't like the Prius, but this has nothing to do with hunting for imaginary gears.See above. Continuously variable transmission, no set-in-metal ratios, no gears to hunt, etc. He's probably got a bad module or else an overactive imagination.Cables fail too, eventually, but otherwise I agree they were simple and reliable. But you've got the throttle response part backwards. Electronically actuated throttles improve throttle response if done properly. Why do you think they showed up on performance cars first in many cases? They improved the throttle response on LS-equipped Corvettes, and moved into more and more vehicles. They also simplify cruise control (no seperate module needed), eliminate the need for a seperate air bypass valve, improve fuel economy slightly, and allow ABS and traction control modules/software to modulate the throttle for better response to road conditions. Hmm, maybe that's where Toyota's problem lies.However, not all drive by wire systems are created equal. If an electronic throttle seems slow to you, its probably either a poor design, or a fuel-efficiency-optimized setup, or if it has a conventional automatic transmission, it is taking too long to decide to downshift (lazy transmission). Most new drive by wire cars should have responsive throttles, especially performance cars. If drive by cable was faster, they'd still be using it in high performance cars at least.http://www.chevythunder.com/drive_by_wire.htm[/citation]
When you stomp on the gas pedal in a CVT, the engine will rev up first, then stay at a higher rev as the CVT changes its own ratios. Many CVTs, including the prius, also have set ratios to switch between, emulating a set gear automatic. If you are cruising at 65mph and encounter a grade to climb, the car will decide to drop the ratio AND add throttle to maintain velocity. If one is only looking at the tachometer, one might make the assumption that the engine is revving through the roof.
A Prius CVT can operate in full CVT, or emulated set ratios, depending on how the computer interprets the information coming from the sensors. A rapid enough climb while cruising, and the CVT will harshly lower the CVT ratio while simultaneously raising the throttle. CVTs are not just transmissions, the entire drivetrain is designed around the transmission, and they only work in conjunction with drive by wire throttles that can be controlled by the same onboard computer that runs the CVT.
He is describing a normal function of a CVT equipped prius, but has been taken off guard by the new version's higher torque and more responsive drivetrain. Combine that with his belief that he is the smartest person on the planet, and you get idiotic comments like this. There are savants that can calculate 10 digit x digit multiplications in there heads accuratly, but can't cook their own meals. Woz might be smart, but hes a fucking fool.
