The entry-level variant is an eight-valve unit that develops 120bhp and 280Nm of torque. Meanwhile, the 16-valve version is good for 150bhp and 315Nm. According to the maker's provisional figures, the CO2 emissions for both models are virtually the same at 157g/km and 159g/km respectively.
What's more, the units fall into the 17 per cent company car tax bracket. That's because they comply with Euro IV exhaust regulations and, unlike many rival models, they have a particulate filter fitted as standard.
All versions of the 9-3 1.9 TiD come with a six-speed manual gearbox as standard. However, the Swedish manufacturer is also offering the option of a six-ratio automatic transmission with wheel-mounted thumbshifters. Started from cold, there's perhaps a little more rattle and thrum than might be expect-ed from a state-of-the-art diesel, but as the car gets underway and warms up, this noise soon diminishes.
We tried the punchier 150bhp version on country roads, and found it to be swift and easy to drive quickly. The 9-3's passive rear-steer self-adjusting suspension gives impressive agility for a conventional front-wheel-drive machine, yet despite the firm handling the ride remains compliant.
The previously sticky shift action of the manual transmission has also been improved, and it's now much easier to keep the powerplant on the boil. But as with most diesels, the TiD engine is at its most impressive when tackling fast, sweeping roads and motorways - here, the steady stream of pulling power only serves to underline why oil-burners have become so incredibly popular on today's market.
We also tried out the new auto. On congested carriageways, the ability to change gear with the flick of a thumb makes progress even quicker and more smooth. In a manual diesel, lifting the throttle to swap cogs can lead to the engine 'dropping off' the torque curve and momentum being lost - but the self-shifter alleviates this brilliantly.
The biggest drawback in going for the automatic is that it results in increased CO2 emissions - which rise to 194g/km. What's more, fuel economy falls to 39.4mpg, stripping the 9-3 TiD of its tax benefits and economy.

Having owned a saab 900 back in the 90's I relished the thought of owning a 9-3 tid 150 bhp - Saab this is not, mine is a 2004 model - and the clues should have been in the substandard stereo, which in all honesty even fell short of my Dad's 1982 metro. Reliability? In November I lost the car to the garage for a total of three weeks after the particulate filter blocked, screwed up the ECU system, and the inlet manifold was blocked which ended up costing me £1200! prior to this the water pump went and last weekend the alternator went costing a futher £800! since when did alternators cost that much! I have only owned this for 10 months! Im glad GM do not own them anymore, hopefully they will get back to their core values of reliability - my saab 900 was finally sold with 180k on the clock without a knock, whine or hiss and didnt cost me a penny in the four years I owned it. Other than the moans, the 150bhp engine is impressive and the fuel is great... and it looks nice... other than that think twice about buying one!.. unless you have a deep pocket!
