The 2-liter Biopower, able to run with E85 has improved power to 200 HP (175 for the previous version) and torque gets a significant upgrade, 300Nm (221 lb/ft). The improvement in power is derived from a new engine management system which controls throttle position, injection and turbo pressure which optimises (or so it's claimed) the fuel mixture that arrives to the combustion chamber.
In the diesel field, Saab has created a new version of the 1.9 TTid with two turbos good for 180 HP. The first one boosts power in the lower rpm range whereas the second kicks in gradually from 1500 to 3000 rpm for higher performance (and less mpg). The announced torque between 1850 and 2750 rpm is 400 Nm (295 lb/ft) - It also makes 0-60 mph in 8.5 seconds. Mileage is near 40 mpg (European combined cycle) and emissions are 159 CO2 g/km.
Will these options be available in the US? As always with European cars, it will depend on their sales previsions and emissions tests, which are different. But GM has good clean technology ready in Europe.
