Performance in the Sebring Convertible is not measured with stopwatches and g-meters. Hang those on it, and it’ll disappoint. Even with the 3.5-liter V6 and six-speed automatic the Sebring feels slow. The other engines are even less impressive. The 2.7-liter V6 is clearly overwhelmed by the car’s mass, and we can assume that the less powerful four-banger won’t do any better. However, if you measure performance by how well the car cruises down the highway, the Sebring isn’t bad. Acceleration in the Limited isn’t terrible, just pokey, and the transmission shifts smoothly and quickly, except in manual mode where it was painfully slow to respond.
