The new, more powerful, twin turbo diesel engine generates torque of 400 Nm from 1,750 rpm, in addition to maximum power of 190 hp. The result is 0-62 mph in under nine seconds. Projected combined cycle fuel consumption are 47.1 mpg and CO2 emissions of 159 g/km, keeping the 2.0TTiD below the 160g/km write down threshold for company car buyers.
The sequential, twin turbocharging system uses two turbochargers of different sizes with by-pass valves that direct the exhaust gas stream between the two turbines. At low engine speeds, the small turbocharger supplies boost pressure independent of engine load. At intermediate engine speeds under higher loads, both the small and large turbochargers provide boost pressure; while at high engine speeds and load, only the large turbocharger is engaged.
This arrangement provides the driver with the 'best of both worlds': instant torque at low engine speeds (via the low-inertia small turbo) and strong, top-end power at higher engine speeds when the large turbo is engaged.
The 2.0TTiD engine is available in Vector SE and Aero specification and can be specified with cross wheel drive (XWD), combining diesel power for the first time with Saab's advanced all-wheel-drive system. All variants are equipped as standard with Saab's sophisticated linked H-arm rear suspension system. This system uses double isolated sub-frame mountings for greater ride comfort, and also reduces vibration entering the cabin and improves roadholding.
The small, highly efficient, 180 hp 1.6T petrol engine epitomizes Saab's rightsizing engine strategy. Developing more than 112 hp per litre, it is among the most powerful series production engines in its displacement class. Sufficient strong power, backed by plentiful torque of 230 Nm from 2,200 rpm to 5,500 rpm (including an 'overboost' function), enables 0-62mph acceleration in 9.5 seconds. Combined cycle fuel consumption and CO2 emissions are 36.2 mpg and 179 g/km respectively. The 1.6T is available in Vector SE specification with front wheel drive and manual transmission.New Saab 9-5 pricing takes off
