Hi,
Yeah I have a pretty good idea, cus one of my very good friend is driving one with auto. It does very poor according to him, around 7 km/l. Sounds terrible to me.
But as I told you, there is an art driving even an auto vehicle. So you must be able to get the same figures at least theoretically.
Handling is always superb in corners in high speeds, way better than a similar range saloon. Recently I drew to Badulla and it was a great drive.
Cheers
