Developed for the US market, the new models preview the next generation of Acura styling, retaining the familiar shield grille and bringing a more bespoke Acura-specific design language.
The ILX will be offered with three powertrains, made up of two petrol options and one petrol-electric hybrid - all from the Civic range.
These include a 112kW/190Nm 2.0 litre, a 150kW/230Nm 2.4 litre, and the 82kW/172Nm hybrid model - the first hybrid in the Acura range.
Like the Civic, all variants in the ILX range are front-wheel-drive and, depending on the model, transmissions include a five-speed automatic, a CVT automatic and a six-speed manual.
The new RDX drops its predecessor's turbocharged 2.3 litre four-cylinder engine in favour of Honda's 3.5 litre V6, developing 204kW - 25kW more than the outgoing engine.
Available in both front- and all-wheel-drive configurations, the new RDX is offered with a brand-new six-speed automatic transmission.
The Acura brand remains a stranger to Australian shores, with Honda's local up-market offerings filled out by the Accord Euro sedan and the larger Legend.
