Both cars new for Australia, the Prevé lands here as the cheapest midsize sedan on the market - retailing at $18,990 for the entry level GX manual.
The GX is also available with a CVT automatic transmission, priced at $20,990.
Power is provided by an 1.6 litre naturally aspirated petrol engine, with 80kW and 150Nm. Fuel consumption is a claimed 7.2 l/100km for the manual, and 8.0 l/100km for the CVT.
Stability control is offered as standard, along with anti-whiplash front headrests, ABS and reverse parking sensors.
Other standard features include Bluetooth connectivity, iPod compatibility and a trip computer.
By mid-2013, a higher-grade variant will join the Prevé range.
Offered with a 1.6 litre turbo inline four and CVT gearbox, the specced up Prevé promises performance equal to that of 2.0 litre naturally aspirated engines, as well as leather, sat nav, rain sensing wipers, dusk sensing headlamps, cruise control and a push button starter.
Also scheduled to join the Proton line-up in mid-2013 is the Exora people mover.
Proton's first seven-seater, the Exora will be powered by a turbocharged inline four with 103kW and 205Nm, with a CVT gearbox as the only transmission choice.
Two grades will be offered: GX and GXR. The base GX gets stability control, dual front and front side-airbags, front anti-whiplash headrests, foglamps, a USB input, Bluetooth and iPod connectivity.
The GXR adds a roof-mounted DVD player, reversing camera, cruise control and electric folding mirrors.
Pricing has yet to be announced for the Prevé GXR and Exora range; further details to be announced closer to their launch.
