Keep reading below, then schedule a test drive in Manchester. Bringing your own numbers to the lot settles this faster than any spec sheet.

The SL 43 suits value-minded drivers and the SL 55 suits power-first drivers in Manchester

The SL 43 suits the Manchester driver who wants a Mercedes-AMG® roadster at the lower entry price. The SL 55 suits the driver who wants the most power in this pair, with 469 hp (Mercedes-Benz, 2027).

The SL 43 makes 416 hp (Mercedes-Benz, 2027) and starts at a lower price than the SL 55. The SL 55 is the step up for drivers who want more output and all-wheel drive. Pick the trim that matches what you will use the car for, and the price difference will make sense.

How much power do the 2027 AMG® SL 43 and SL 55 make?

The SL 55 is the quicker of the two to 60 mph, by the manufacturer’s own estimate of 3.8 seconds (Mercedes-Benz USA, 2027).

The SL 43 delivers 369 lb-ft of torque from 3,000 to 5,000 rpm (Mercedes-Benz USA, 2027). The SL 55 uses a Handcrafted AMG® 4.0-liter V8 biturbo that makes 516 lb-ft of torque from 2,250 to 4,500 rpm (Mercedes-Benz USA, 2027). That gap in torque shows up most when you accelerate from low speeds.

Which drivetrain does each 2027 AMG® SL have?

The SL 55 has all-wheel drive, the AMG® Performance 4MATIC®+ system (Mercedes-Benz USA, 2027).

If you want the all-wheel drive system, the SL 55 is the trim that offers it. If rear-wheel drive suits how you drive, the SL 43 gives you that layout at the lower starting price.

What do the 2027 AMG® SL 43 and SL 55 cost?

The SL 43 starts at $114,900 (Mercedes-Benz USA, 2027). The SL 55 costs more to start, and its price pays for the extra power.

The SL 55 starts at $147,750 (Mercedes-Benz USA, 2027). Our sales specials include rotating Mercedes-Benz lease and finance specials, so the starting price is not the only number to compare. A lease or finance offer changes what you pay each month, which makes it worth comparing both trims on the same terms.

What are the 2027 AMG® SL 43 and SL 55 specs side by side?

The SL 55 costs more, makes more power and torque, and adds all-wheel drive. Each figure below is the manufacturer’s own 2027 specification.

The difference in price buys the SL 55 more power, more torque and all-wheel drive. If you will not use that output on the road, the SL 43 covers the same roadster experience for less money.

Who should skip the SL 43, and who should skip the SL 55?

Skip the SL 55 if fuel economy matters most, since it is rated 16 mpg combined (U.S. Environmental Protection Agency, 2026).

Skip the SL 43 if the goal is the most power and all-wheel drive between these two trims. The SL 55 offers both. Buyers who want the lower starting price and the better combined rating should start with the SL 43.

What taxes and fees apply when you buy a 2027 AMG® SL in New Hampshire?

New Hampshire does not charge a sales tax on a new vehicle bought from a New Hampshire dealer (New Hampshire General Court, RSA 78-D:1). The costs you will pay are registration fees, not a sales tax.

The state registration fee is $48 a year for vehicles from 3,001 to 5,000 lbs (New Hampshire Division of Motor Vehicles, 2026). New Hampshire also sets a municipal registration permit fee of 18 mills on each dollar of the maker’s list price for a current model year vehicle (New Hampshire Revised Statutes Annotated, RSA 261:153, 2026).

In Manchester, that municipal permit fee is $18 for each $1,000 of MSRP (City of Manchester, NH). Manchester’s Municipal Agent fee is $3.00 on registrations completed on behalf of the Division of Motor Vehicles (City of Manchester, NH). A first set of plates carries an $8.00 plate fee (New Hampshire Division of Motor Vehicles, 2026).
