I have three diesels.

On my 300D, it keeps up with traffic and I generally don't push it unless I feel like going fast. I've never had a problem with passing or going too slow and I can always keep the right speed on hills.

On my motorhome, I tested my 0-60 at about 37 seconds. This is with a 3.9l Isuzu diesel. At 13,000 pounds I can command traffic around me. On flat ground, it may be faster than a 240D, maybe...

On my VW Tdi, I have had a few times at least where I fear not being able to accelerate fast enough. On my recent trip through Washington, there were at least a few hills where I could not maintain speed. Still, it is faster than a 240D, but at 90hp I drive it like I am trying to steal it.

Dkr.
