70 to 0 MPH
Car and Driver
The ATS Coupe’s 225/40R18 front and 255/35R18 rear tires provide better handling because they have a lower 40 series front and 35 series rear profile (height to width ratio) that provides a stiffer sidewall than the LC Series’ standard 45 series front and 40 series rear tires.

When the ATS Coupe with available tilt-down mirrors is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The LC Series’ mirrors don’t automatically adjust for backing.
For greater rear passenger comfort, the ATS Coupe has standard rear a/c vents to keep rear occupants more comfortable. The LC Series doesn’t offer rear vents.
The ATS Coupe offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The LC Series doesn’t offer a house-current electrical outlet.
