| 467222 | 2006-07-04 11:07:00 | Then use what method to save fuel, Mr? All of personthingy's points plus a light right foot, keeping to the speed limits, not driving too fast on the open road because wind resistance/ drag increases exponentially with speed (which is why an F1 car only goes about twice as fast as a good road car despite low weight, low drag and powerful engine). Lifting off the accelerator when going down hills is a good saver too, there's no point is dissipating the energy created by burning petrol as heat from your brakes. Cheers Billy 8-{) |

A short shift won't work, most cars have no powers going uphill with high gears. :D I love the 1st gear in exotics. The can drag up to 100km/h plus then change gear. But people prefer putting their engine in low RPM to save fuel. |

They can slipped easily if you can't drive them for the first time. And their values will dropped fast too. Using a fixed car is a better idea, rather than losing money. | MTLance (6768) | ||

| 467230 | 2006-07-04 20:42:00 | Why does most vehicles on highway use less fuel?:confused: I get the feeling that you don't actually drive yet MTL, and that you don't really know much about cars either, you just like reading about them . All vehicles use less fuel on highway use, regardless of size shape fuel or purpose . When driving on the open road (highway cycle) although driving at a faster average speed, you are cruising for much of the time in top gear with a set accelerator pedal position and a steady speed . Under these conditions the engine uses minimum fuel . When driving around town (city cycle) you are contantly accelerating, braking for corners or stop signs then accelerating again, sitting idling at lights etc . Also for short journeys the engine doesn't reach optimum operating temeprature and is less efficient . In addition, cars have an accelerator pump (for want of a simple expression, it can take a variety of forms) that injects an extra burst of gas when you want press tha accerator down rapidly . In simple terms, this ensures that you accelerate smoothly and if the pump isn't working, you get a cough (jerk) as the engine tries to catch up with your latest demand . The more times you press hard down on the accelerator, the more fuel you pump . All of this uses more fuel than the highway cycle cruise, as you will find out when you actually start driving and/or paying for your own fuel . You will become keenly interested in how fast the needle goes from F to E . Cheers Billy 8-{) |
