The DB12’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the AMG SL.

Both the DB12 and the AMG SL have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, blind spot warning systems, around view monitors, rear cross-path warning and driver alert monitors.

Warranty

The DB12 comes with a full 3-year/unlimited-mile basic warranty, which covers the entire car and includes free 24-hour roadside assistance. The AMG SL’s 50,000-mile basic warranty expires sooner.

The DB12’s corrosion warranty is 5 years longer than the AMG SL’s (10 vs. 5 years).

Engine

The DB12’s 4.0 turbo V8 produces 202 more horsepower (671 vs. 469) and 74 lbs.-ft. more torque (590 vs. 516) than the AMG SL 55’s standard 4.0 turbo V8. The DB12’s 4.0 turbo V8 produces 94 more horsepower (671 vs. 577) than the AMG SL 63’s standard 4.0 turbo V8.

Fuel Economy and Range

On the EPA test cycle the DB12 gets better mileage than the AMG SL:

			MPG
DB12
	RWD	4.0 turbo V8	15 city/22 hwy
AMG SL
	AWD	63 4.0 turbo V8	14 city/22 hwy
		55 4.0 turbo V8	13 city/21 hwy

The DB12 has 2 gallons more fuel capacity than the AMG SL (20.5 vs. 18.5 gallons), for longer range between fill-ups.

Brakes and Stopping

For better stopping power the DB12’s brake rotors are larger than those on the AMG SL:

	DB12	AMG SL

Tires and Wheels

For better traction, the DB12 has larger tires than the AMG SL (F:275/35R21 & R:325/30R21 vs. F:265/40R20 & R:295/35R20).

The DB12’s 275/35R21 front and 325/30R21 rear tires provide better handling because they have a lower 35 series front and 30 series rear profile (height to width ratio) that provides a stiffer sidewall than the AMG SL’s standard 40 series front and 35 series rear tires.

For better ride, handling and brake cooling the DB12 has standard 21-inch wheels. Smaller 20-inch wheels are standard on the AMG SL.

Suspension and Handling

Chassis

The Aston Martin DB12 may be more efficient, handle and accelerate better because it weighs about 600 pounds less than the Mercedes AMG SL.
