Lexus Australia has confirmed its incoming ES sedan range will kick off with the 350 petrol and 300h hybrid models, due here later this year.
The carmaker has also locked an early 2014 local debut for the new GS 300h hybrid, revealed at the Shanghai Auto Show earlier this year.
Despite wearing the same 300h moniker, the ES and GS hybrids are far from identical, with unique platforms and powertrains separating the two.
The ES represents a more affordable alternative to the GS, and will enter the local range between the new incoming IS and the current GS range.
The GS rides on a longer wheelbase (2850 vs 2822mm), but the ES is slightly longer overall at 4895mm (4848mm for GS). A broader cabin and pumped guards makes the GS wider however, measuring 1840mm to the ES' 1821mm.
And while the two are similar in size, the ES sits on a front-wheel-drive platform, while the GS features rear-wheel-drive architecture.
Outputs also differ for the hybrid models: the ES 300h's 2.5 litre four-cylinder petrol-electric setup offers 151kW, while the 2.5 litre direct-injected GS 300h offers 164kW (identical to the smaller IS 300h).
"The return of ES to Australia is a direct result of continued customer demand and we are pleased to have secured not one but two options for them while simultaneously expanding our innovative hybrid vehicle portfolio," Lexus Australia boss Sean Hanley said.
"The addition of these three new models gives Lexus a distinct advantage in the luxury vehicle segment, offering a peerless product in ES and our seventh hybrid vehicle in the form of GS 300h," Mr Hanley said.
