If you read the Edmunds reviews they say:
"Sharper handling than you would expect from a Volvo"
"The new S40 is fun to drive"
"Firm suspension can be choppy on the highway"
"The S40 looks, acts, feels and performs exactly the way we think an
entry-level Volvo should."
"This small Swede is certainly a worthwhile addition to your shopping
list."
"Volvo tuned the S40 to take performance much more seriously than the
previous-generation model."
"Handling is crisp and entertaining, though the standard tires are taxed
by more aggressive cornering."
"The downside to the S40's sharp reflexes is that cruising comfort
suffers."
"Firm suspension can be choppy on the highway"
Personally I like sharp handling and firm suspensions. Most of the
mush-mobiles cruise nicely but don't handle well off the interstate.
