This allows the vehicle to travel 0.2 more miles, a 20% increase.</span></p> <p>Apart from the unitless (and therefor meaningless) 0.0693 (which is your error not the competition winners) it is the concept that is at fault, clocks can&#39;t wind themselves up, and neither can electric cars.</p> <p>MK</p> <p></p><img src="https://community.element14.com/aggbug?PostID=24817&AppID=75&AppType=Weblog&ContentType=0" width="1" height="1">
