This one is based on Saab mechanicals. It is available with 2 litre turbo engine which has 200bhp or a 2.3 litre turbo engine which develops 250bhp (the engine from the old 9-5 Aero). The only transmission available is a 5 speed automatic, altough that could change "at a later date".
There's also a 1.8 litre engined version for government officials.
Oh, and Nicolas Cage advertises it!
