The new Saab 9-3 Aero TTiD range boasts a 1.9-litre two-stage turbocharged diesel engine delivering 132kW and 400Nm of maximum torque.
The engine features two sequentially mounted turbochargers of different sizes which can either operate separately or in tandom.
From idle the exhaust gas feeds only the small turbo, at 1,500rpm the flow is then split between both turbines until 3,000rpm where only the larger turbocharger is engaged.
Matched to either a six-speed manual or six-speed automatic transmission, combined fuel consumption is just 5.7 litres per 100km for the manual Sport Sedan model.
