Opel Zafira Reviews

GM and Toyota have used the forum of the Frankfurt Motor Show to spruik their green credentials. Toyota executive Mike Hawes told reporters his company was investigating biofuels.Toyota has 10 years of experience with its Prius hybrid, which combines an electric and a petrol engine. But this endlessly vaunted car comprises only a tiny fraction of Toyota's sales.General Motors, meanwhile, has developed vehicles that use petrol mixed with ethanol, so-called E-85-capable cars and trucks.Both companies are working hard on technologies and presented their options at the Frankfurt fest.GM Europe president Carl-Peter Foster said makers would probably focus on a range of solutions, as no single technology covered all needs.GM highlighted several electric models at the fair, one of the sector's biggest showcases. Analysts forecast that most carmakers will have a hybrid option in their line-up within the next five years.Ethanol is used in what are also known as flexible-fuel vehicles. These use engines similar to petrol ones, but running on a blend of up to 85 per cent ethanol, hence the E85 tag.The big question, however, is cost. According to some estimates, 'clean' technology can add around $A4000 to the price tag of an SUV.Fuel cells are even more expensive, but are the most promising long-term solution. Toyota announced it would market a fuel-cell car, costing about $A60,000, by 2015.Another implication of the green evolution is having to learn a whole new range of auto jargon. The latest automotive JargonBluemotion Volkswagen's name for the fuel-saving versions of its Polo, Passat and Golf models. The savings are made thanks to narrower tyres and lighter bodywork. Bluetec This is the technology Mercedes-Benz uses to make diesel cars just as clean as petrol engines.The system reduces diesel particles by as much as 80 per cent, An oxidising catalytic converter and a particulate filter combine with other systems to reduce nitrogen oxide. Brake energy recuperationA BMW system in which the energy lost through heat while braking is used to recharge the battery. Fuel cellHydrogen fuel cell vehicles are seen as one way to dramatically cut greenhouse gas emissions.Hydrogen that is used in the cells is extracted from petrol or natural gas, and a chemical reaction with oxygen produces energy.The only by-product is water. The main drawbacks are the energy needed to produce hydrogen and the infrastructure required to make it available. Diesel hybrid The most common hybrid engine is acombination of electric and petrol, but some producers favour an electric-diesel hybrid because diesel engines use less fuel. DiesottoA petrol engine offering the high torque and fuel economy of a diesel, paired with extremely clean emissions. Mercedes calls it "the future of the petrol engine." Ecoflex Opel's name for a range of low-consumption, low-polluting models with small electric and diesel engines that were launched at theFrankfurt show. Econetic Ford's name for a new range of cars with lowered suspension, aerodynamic profiles and narrow tyres that help reduce both emissions and fuel consumption. The first model is expected in 2008. Efficient dynamicsBMW's environmentally friendly cars using Stop-Start Technology. Electric enginesElectric cars produce no emissions, and significant progress has been made in prolonging battery life. Hybrids Cars such as Toyota's Prius and Honda's Civic that use a combination of petrol and electric engines. In town, hybrid cars mainly use the electric function. For longer- distance driving, the petrol function can be switched on. Stop-start technologyThe engine cuts out when the vehicle comes to a halt and automatically starts again when it needs to drive off.

While a rose by any other name is supposed to smell as sweet, there's a whiff of weird to some of the bizarre car names manufacturers dream up.The Mum 500 is far from being the only example of what an obviously fevered marketing brain thinks might be an attractive label.Joining it in the cheery Mitsubishi family was the Chariot Happy, while Suzuki has also dipped into the smiley juice with the Every Joy Pop Turbo. Honda launched a Joy Machine and Toyota had the Estima Lucida G Luxury Joyful Canopy.Was it an after-effect of the ubiquitous smiley symbol? Or could a hint to what was in the water cooler at the time be found in the hippie-flavoured Mitsubishi Mini Active Urban Sandal?Human body parts have also been an inspiration and an indiscretion. There was the innocuous Nissan Big Thumb and Ford Synus and Daihatsu's revealing Naked.Mitsubishi's blunder with Pajero (Spanish for err, self-pleasure) was matched by Honda's Fitta and Opel's Ascona, words for female genitalia in Swedish and Spanish.Spanish also offered pitfalls for Mazda's La Puta, translated as “the prostitute”, while Toyota's Fiera was “hideous old crone”.The light commercial segment also tried to enhance a vehicle's utilitarian base with an expressive name. You can understand the thinking behind Mazda Bongo Brawny and perhaps even Bongo Friendee and Mitsubishi Canter Guts. But Isuzu takes it to peculiar extremes with the Giga 20 Light Dump.But no matter what language you try to translate them into, others are simply incomprehensible and illogical, like the Suzuki Van Van.
