BYD Sealion 5 vs Renault Koleos
A detailed look at how two of Australia's most popular SUVs compare on price, running costs, safety, and everyday livability.
Specifications and pricing correct at time of publishing. Prices are RRP before on-road costs unless stated otherwise. Always confirm with the manufacturer or dealer before purchasing.
Plug-in hybrid fuel economy is shown as a hybrid (battery depleted) so it compares fairly with the other car. A PHEV's official "combined" figure assumes you start every trip fully charged, so real-world economy depends on how often you plug in. Electric range shows how far it goes before the petrol engine is needed.
