IN Carsguide’s recent green car story there was a table showing zero CO emissions for
2 the Mitsubishi iMiev. As an engineer I believe it is quite misleading. This car obtains power from electricity, which is generated by coal-fired power stations with a thermodynamic efficiency of less than 40 per cent, or about the same as a combustion engine after you take into account the transmission losses. To be fair and honest, the table should be calculated by working out the kiloWatt hours-per-hundred kilometres. Then we can work out how much coal was burnt and the amount of CO that was
2 actually generated.
RayMouw, email THE Government’s ratings only take account of what’s burned in an internal combustion engine. Perhaps they should talk instead about
‘‘ total emissions’’. As for coalfired power— that’s another can of worms entirely. COMING SOON CAN you tell me why Ford keeps on delaying the release of the new Territory, and will it be a good car?
RodMcLennan, email THE delay was caused by a computer glitch involving the dashboard display. Ford says it’s fixed and orders are being filled. We’ve driven it and it is very impressive, not just for the diesel but improvements to refinement, looks and driving. DRIVER SKILLS MY daughter will soon turn 18 and hopes to get her driving licence next month. Can you please recommend a reputable organisation that can give my daughter practical, hands-on tuition in the skills of avoiding accidents and knowing how to react in sudden, dangerous situations. To date my wife and I have been teaching her in a late-model auto Commodore. We started in a manual Toyota Echo but once she got the taste of the auto there was no looking back. Pity, but there you are. I have no intention of letting her go solo in such a car but will follow your recommendation of getting a Subaru Liberty or something similar unless you can advise otherwise.
Anthony Willis, email CARSGUIDE has had very positive experiences with Murcotts Driving Excellence and John Bowe Driving, two organisations with a strong focus on safety and young drivers. The Liberty would be an excellent choice for a safetyfirst car for a youngster. CLASSWARFARE VICTORIAN school-zone speed restrictions really annoy me. There is rarely a kid in sight most of the time restrictions apply. The SA version is better as restrictions apply ‘‘whenever there are children present’’, regardless of time. The other annoying thing is that if a school is in an 80km/h zone, the restriction is down to 60, but if it is in a 60 zone, the restriction is down to 40. Why?
Patricia Woolcock IT’s typical of variations in the rules between states. KEEPING KIDS SAFE I AMconcerned about Carsguide’s ‘‘Protecting your most precious cargo’’ report in April. In particular, the statement: ‘‘Fitment of a child seat is possible in the front seat, provided the airbag is deactivated’’. An associated picture showed a young child in a rearward-facing child restraint in the front seat of a car. New national child carrestraint laws clearly state that children under the age of four years are not to ride in the front seat of a vehicle that has more than one row of seats. Children aged from four to seven years can ride in the front seat only if all rear seats are occupied by younger children. While it is not illegal to use a restraint in the front seat of a vehicle with only one row of seats, many such vehicles have no anchorage point and cannot have a child restraint fitted. Parents and carers must follow the recommendations in the vehicle handbook before fitting a child car restraint in the front seat. As there is still much confusion among parents in relation to the new child car-restraint law, please clarify this point. Hopefully, this letter has. Helen Noblet, Holly Fitzgerald
