Fuel economy

A more stringent standard for fuel economy (WLTP) was introduced from September 2017, and this model was not required to undergo that test. Its fuel economy measured under the previous test system was 25 - 54 mpg. However these figures are less likely to be achievable in real world driving and so should never be compared to another car's mpg which was measured under the newer, more realistic WLTP system.

Most of the engines, except for the 2.8-litre, offer decent economy considering the performance on offer. But as always, it’s the diesels that are best for low running costs, especially if you’re going to be covering long distances. Service intervals are long, but dealer rates are comparable to other premium brands. Luckily, there are plenty of independent dealers who offer lower labour rates.

The 9-3 scores fairly badly on the eco front. With an average of 200g/km CO2 across the range, its emissions are a touch high for a medium-sized convertible. The greenest engine is the 1.9-litre diesel – both the 150bhp and 180bhp versions emit 154g/km of CO2.

Saab has a good reputation for reliability so you can expect the 9-3 Convertible to be generally reliable as long as you maintain the servicing schedule.
