The Mercury Cars Guide : July 17th 2010
Saturday, July 17, 2010 Classifieds 62 300 400 carsguide.com.au ---3 way to the fuel pumps in carefully measured tiny amounts under enormous pressure thanks to modern ''common rail'' injection systems. The injection process is helped by cleverly-designed turbo- chargers (using the engine's exhaust gasses to spin a turbine that pushes more air, and therefore oxygen, into the cylinders). Combined with optimised shape of the combustion chamber, there is great efficiency of power achieved from every drop of fuel, a help to fuel economy and emissions. Similar work is being done on petrol-fuelled engines but the standout characteristic of diesel en- gines torque, or pulling power, at low engine revs gives them an advantage of fuel economy. Diesel cars can get into their higher gears sooner and at relatively low speeds. And once settled, the engine ticks over at a low speed and so uses less fuel. Take the Fiat 500, for example. It's 1.4-litre engine running on petrol is quite economic. Maximum torque of 131Nm comes at 4250rpm and its official fuel econ- omy is 6.3 litres/100km. But its 1.3-litre JTD diesel brother has more torque, 145Nm, at about a third of the engine speed, 1500rpm, and its fuel economy is 4.2 litres/100km. The little petrol engine uses 50 per cent more fuel while giving similar on-road performance. The top petrol-only car on the fuel economy list from www. greenvehi- cleguide.gov. au is the tiny smart fortwo. It has an engine of just one litre size and three cylinders and is only a two-seater. But its light weight means the modest 55kW power is enough. Hybrid cars --- those that have a conventional engine plus an electric motor, exemplified by the Toyota Prius --- come into their own in stop- start commuting. Normally, when a driver presses the brake pedal it is the enemy of fuel economy: you've burnt fuel to build speed only to waste it by braking and converting to heat energy that is lost. The hybrid car harnesses that energy, like an electricity generator, and feeds it to the battery pack for an electric motor that assists propelling the car. But hybrids are not so beneficial in open road driving where they run on their conventional engine only and still carry the weight of the electric motor and batteries with little chance to use brake regener- ation. However, the Prius is the third-best in fuel economy of all cars. Some fuel-wise cars have stop- start: when the car is stopped and in neutral, the engine shuts off. It restarts as the driver presses the clutch pedal to move into gear. Engines done, the auto engineers then enhance the efficiency of their fuel misers by making them light in weight (they ditched the spare wheel of the Ford Fiesta ECOnetic to cut weight) and they run on low-rolling resistance, thin, tyres. Aerodynamics also get attention. Look at the plate-style wheel covers on the Volvo C30 DRIVe. The Fiesta ECOnetic sits lower than other Fiestas and has a deflector skirt under the front wheel while the MINI D has underbody smooth airflow design. Prius boasts a drag co-efficient of .25 (anything below .3 is commendable; this is very good for a four-door). Fuel cost of running a petrol versus diesel car depends on the relative prices of the fuel but in recent times there has not been much difference between them. Only one of our top five can be had with an automatic transmission, the MINI charging $2350 extra for its sophisticated six-speed automatic. Visit www. greenvehi- cleguide.gov. au for ratings.
