Everyone is obsessed with speed, but not every car is designed to give you the thrill of going from 0 to 62 mph in under four seconds.
In fact, many of Australia’s best-selling cars offer only modest performance figures, so we’ve decided to put together a list of the 10 lowest power-to-weight ratio cars currently on sale.
We did this rather than simply rating vehicles based on overall performance, as power versus weight is much more relevant in the real world.
We’ve also mentioned claimed 0-100km/h times if these were provided by a manufacturer. However, most of the cars on this list do not have stated acceleration figures for obvious reasons.
Are you surprised by the cars here? Let us know in the comments below.

BYD Dolphin Essential
The base BYD Dolphin currently has the lowest power-to-weight ratio of any new model currently available in Australia, achieving output of just 46.5kW per tonne.
70kW in total isn’t much when you’re trying to move the Dolphin’s 1,506kg, which gives a claimed 0-100km/h time of 12.3 seconds. Its 44.9 kWh battery is said to be able to travel 340 km (WLTP) on one charge.
At $29,990, it’s at least somewhat affordable before on-road driving. However, if you need more power, you can upgrade to the Dolphin Premium for $36,990 before hitting the road. It has an output of 90.5 kW/t and accelerates to 100 km/h in just seven seconds.

While it can only travel 220km (WLTP) on a charge, it’s incredibly affordable at $23,990 before on-road use. The more expensive Atto 1 Premium achieves a range of up to 310 km and increases the power-to-weight ratio to 82.7 kW/t. Pricing is $27,990 before on-road launch.
