To echo a point made earlier. They bang on about the whine of a cvt but not an engine bouncing off the limiter.
By asking for full throttle maximum acceleration. The ICE goes to max output and rev limit and stays there. Very efficient. In the mean time the CVT does it's thing to bring the road speed up to the desired/appropriate level seamlessly. The moment the desired speed is achieved. Foot off the accelerator, and lightly back on, ICE revs plummet. CVT again adjusts to maintain speed. Now in virtual silence as ICE is maybe doing 1450rpm @ 70mph (rx400h)
By asking for full throttle maximum acceleration. The ICE goes to max output which is likely to be making far more noise, then a change of gear is required and the process starts again, regaining the lost revs due to the change. The moment the desired speed is achieved. Foot off the accelerator, and lightly back on, ICE revs reduce. ICE is maybe doing 3000rpm @ 70mph. Obviously talking petrol not diesel as Lexus do not do diesel.
Does the CVT whine or is it the ICE? But how long does it last? Once up to speed. Noises off. Can the same be said for traditional, normal box, DSG or other wise.
Talking to the converted here. But just needed to air that.
Horses for courses. The IS is about luxury and arriving in style. (side observation, how few I have seen on the road. 1. Exclusivity!) I don't even have one yet, but I get it. I like my creature comforts. But, I am also happy listening to my MR2 (even fewer) sing it's own song.
Once the penny dropped in the Prius. CVT = linear delivery. In my urban commute world, 0-30 0-40 far more relevant than 0-60. To pull away from the lights and arrive at 30 - 40 seamlessly just gives me a warm fuzzy feeling. The Prius,viewed by many as the slowest car in the world. Er, nope. I'm at the regulation speed before many have even grabbed for 2nd. Too late. Nothing to do with racing, but just sitting there at the lights, no ICE, utter silence and then 400nm of torque (if required) from 0 revs silently delivered in a linear manner. To think that was a 1.5
