Despite diesel not being my first choice of fuel back in 2010, I'd become quite obsessed with the new Turbo innovation by Saab, the TTiD. At the time, I'd tried a whole host of competitors, from the Alfa 159, Mercedes C Class, Audi A4, BMW 3 series and the Jaguar XJ, but after driving the Saab 9-3, it was hard to change my mind.

Yes, it was more individual and the facelift had made the 9-3 look truly fantastic, but it was the wonderful diesel engine that left a lasting impression.

A two-stage Turbo – the latest development of Saab's turbo engine technology, delivering refined performance, torque and economy. It features one smaller and one large turbocharger which co-operate to provide higher torque over a wider rev range. The small turbocharger works alone up to 1500 r/min, after that the second-stage turbo kicks in and both chargers run. Above 3000 r/min, the larger turbo charges the engine alone.

"It’s the power delivery that makes it stand out. Saab has integrated a two-stage turbo for a broad, linear spread of shove and crisp, near-instantaneous throttle response."

Having a budget of around £30 - 35k at the time, gave me the perfect opportunity to not only choose the Saab 9-3, but to completely upgrade it to Hirsch specification from the Saab dealer. It meant being able to push the already lively performance up to 200hp and 430Nm of torque, which made a noticeable driving difference. And the crowing glory, only 119Co2 and £30 road tax a year.

Interestingly, 14 years on and having the opportunity to own and drive the very same 9-3 again, has been enlightening, the Saab TTiD still feels lively and responsive, and at speed, the diesel engine settles down to a very refined level and enables you to cruise quietly along in Saab's legendary comfort. So far the efficiency seems to have been maintained, with an initial average of 40mpg.
