The Astra isn't the only GM model getting a new diesel option
. The performance Aero model of the Saab 9-3
is now available with a 177hp 1.9L diesel
. The 295lb-ft of torque is apparently enough to motivate the 9-3
Aero TTiD at similar rates to the gas engined version. The gas-fueled model however cannot approach the 41.3mpg (U.S.) rating of the manual transmission model. Even the automatic version achieves 34.6mpg (U.S.). The diesel in the Saab
has the two-stage turbocharger setup with a smaller turbo for quick low speed response and a second larger unit for maximum power. Here in the U.S., the Aero with the 2.8L turbo V6 is rated at a mere 16/24mpg by the EPA
. Even accounting for differences in test procedures, the diesel is clearly far more efficient than the V6. Unfortunately, here in the States we again
don't have this option.
