The range will start at £18,495 on-the-road for the new 150bhp 1.8t Linear, with the 125bhp 2.2 TiD diesel derivative costing the same.
From the base model, Arc and Vector trim cars will cost £1,800 and £2,000 more respectively, while a step up to the 175bhp 2.0t engine will result in a further £1,100 increase.
Linear models include alloy wheels, CD/radio, traction control, headlamp washers and leather-covered steering wheel, while Arc models add leather seats, poplar fascia panels, climate control and front fog lamps. Vector models include larger wheels and sports seats.
Next year the 9-3 Aero will go on sale at £22,895 on-the- road and will include a six-speed manual transmission, electronic stabilisation programme, upgraded chassis and bi-xenon headlamps.
Although final servicing costs and carbon dioxide emission figures are to be confirmed, Saab claims the new 9-3 will offer fleets reduced running costs and competitive P11D prices.
