A snapshot of who AI is recommending right now, not a fixed ranking.
The exact prompt we asked
I'm financing a car in Australia and want the lowest car loan rate. Which lenders are best? Give me a ranked top five of named lenders, each with the rate and a one-line reason.
Asked to ChatGPT, Gemini and Google AI Overviews, up to 100 times each. Everything below is measured from their answers.
The short answer
There is no clear winner for car loans in Australia. ChatGPT names loans.com.au first but only 8% of the time, Gemini leads with BankWAW 96% of the time, and Google AI Overviews puts Harmoney first. MoneyPlace is the only brand all three engines share.

What kind of sites get cited
This is what AI links to as its sources, which is not the same as the brands it names above. AI often recommends a provider by name but sends the citation to a publisher or affiliate instead, so “First-party brand” means a link to the provider’s own website. Here is the mix by engine.

The themes behind the recommendations
Looking past the brand names, these are the concepts and buyer intent the AI answers kept returning to for this product. Each finding starts with what the engines foreground, then what it means for you.
The AI answers for Australian car loans revolve almost entirely around finding the lowest advertised interest rate, with the result steered heavily by credit profile and the type of vehicle being bought.
Lowest advertised rate wins
ChatGPT, Gemini and Google AI Overviews all rank lenders by the lowest starting or "from" rate they can verify, treating the headline number as the main reason to pick one lender over another. A brand that does not surface a sharp advertised rate on comparison sites like Mozo, Canstar and Money.com.au is unlikely to be named at all.
Green and EV loans favoured
The answers repeatedly call out that the cheapest rates go to electric and hybrid vehicles through green car loans, with BankWAW named for leading on that category. Lenders without a distinct green or EV product are framed as more expensive by default, so the eco angle has become a fast route to the top of the list.
Credit and comparison-rate caveats
Every engine warns that advertised rates are credit-assessed and change with the borrower's score, the car's age and loan size, and Gemini and AI Overviews push readers to judge on the comparison rate that includes fees. The practical implication is that a low headline rate alone is not enough, and brands are also assessed on the honesty of their total cost framing.
