wow, ive never seen such total and utter drivel flow from one persons keyboard before in regards to the t-sport. its the first time ive ever heard anyone attempt to pass off high speed instability on a corolla as a result of the 'rear wing pushing down making the front rise up'. jokes central! lol. ill think of this the next time im shooting up the m1. as for why is you car so economical compared to everyone elses, theres 2 options, its either slow as %$(, or the figures are wrong. i can gurantee you that plugging a laptop in is not as accurate as doing the maths pre and post pump. as many owners on here know the trip comps are more than often totally wayward. mine once read 73mpg....... i also dont see how your little test thing applies. even i can get 40 mpg driving like little miss daisy over a short distance. real world driving, real world speeds, admitedly ***** about from time to time..... under 20mpg. anyway, thanks for the link to this. well worth logging in for the first time in a while! ;)
