ICh has already read several times that the smart wouldn’t be so good for the highway, is that true? Why not? Spring comfort ? Problem with track grooves ? Volume ? What is the realistic usage at 90 – 100 km/h ? I have 50 km to work every day and 50 km back and am more the one who gets stuck at 90 km/h on the right track. The track is 80/100/130 partly open. With an A 170 CDI I am sometimes at maximum speed, where you were allowed to drive 190 km/h and otherwise always 20 km/h s Has much 10-12 min saving brought me on the complete track and more than twice as much consumption. By the way, how is the sound system in the Smart Fortwo?
