Economy comparison test part two
The aim of part one was to find out which of the four cars on test ? Audi A3 e-tron, BMW i3 range-extender, Citroen C4 Cactus and Toyota Prius ? was the most efficient, city-friendly commuter. And the winner was clear.
Conclusion
After a fair old stint if highway driving, we saw some intriguing numbers. Some lower than expected, and some not so much.
The BMW i3?s trip computer read 258.3km when we eventually refuelled (we purposely didn?t use the jerry can, though Trent did on the return leg back to Sydney). At that point, it had 1km of EV range and no fuel left.
Now, we know the BMW doesn?t have a fuel use readout, but we filled its 9.5-litre tank to the brim at the beginning of the trip and it took 9.35L at the end while showing empty (or $12.62 at a price of $1.35/L).
And if you do the maths, it used 3.6L/100km, plus the electricity use, which averaged at 16.3kWh/100km: figuring out the exact amount of electricity consumed is impossible, but it would have to be about $5.00 based on an average of $0.23 per kWh. So, an estimate would be about $17.00 for the trip.

The Prius?s trip computer read 257.3km and it used 4.7L/100km, with an electric driving ratio of 20 per cent ? so, every fifth kilometre was driven using electricity, not petrol. It cost $16.11 to fill.
The Cactus didn?t have electric bits helping out, and while its trip meter read a little lower than the others (252km), it averaged 4.7L/100km on screen ? identical to the Prius. It cost $14.21 to fill, but at a cost of just $1.18/L, as Taralga is not just wind-farming country, but actual farming, too.
The Audi, somewhat surprisingly, was the thirstiest on test. It used an average of 4.9L/100km, and with a fill cost of $18.63 ? plus the cost of the electricity to fill its battery bank (8.8kWh ? or approximately $2.00) ? and the A3 is not just expensive to buy, but also the most expensive to run of these four.
Surprised? We were too.
