Consumer Reports not too pleased with Yaris - Toyota Yaris Forums

well now, i dont know much about all of this, but i was looking at these numbers.

if he went 0-53mph in 6.5 seconds that means 53/6.5 yields an average accelleration of 8.153 mph/second. Now, from what i have read on yaris world it seems that the Yaris has much better acelleration from 0-40 than say, 40-70, or even 40-60. So lets say that his rate of acelleration is decreasing from 40 mph so that he is getting about an increase of 7.153 mph every second. Then he hits fifty and his rate of acelleration slows to lets be generous and say about 6.65mph/second. that means at 53 mph it would take him an additional second to reach 60 mph. that would put him at 0-60 times of 7.5 seconds, throw in human error (since it sounds like he doing this alone?) and it could easily be 8 seconds. so maybe in a manual on a slight incline?

Further, my understanding is that modern cars naturally read slightly higher than they are actually going as a safety precaution which could cost him an additional 3 mph off his recorded time, that would then mean an additional .5 seconds added to his time making his reading a possible 8.5 second time.

I suppose since many of you are getting low 9s for manual its concievable that a good driver might, on some occasion, break into 8? especially if there were a slight, maybe not very perceptible, downhill slope. Or perhaps the switch from second to third would cost more time and have reduced his speeds by larger amounts, meaning that he would have been right in the sub nines with the rest of you guys for 0-60 times?

maybe i am crazy, but just some thoughts from an idiot.
