Mercedes-Benz SL55 AMG Performance Overview
Mercedes-Benz’s SL55 AMG, sold in this form from 2003 to 2004, sits within the R230 SL-Class as a short-run performance roadster defined by AMG’s supercharged M113K V8 and a gasoline-only layout. Across 3 verified tests spanning 2003 to 2004, its 0-60 times range from 4.1 to 4.8 seconds, outlining a narrow but clear performance window for the model years covered.
The timeline starts with the 2003 SL55 AMG Roadster, which recorded 0-60 in 4.5 seconds as the earliest benchmark, while another 2003 Roadster test returned 4.8 seconds. In 2004, the Kleemann 55K3 Roadster reset the pace at 4.1 seconds to 60 mph and ran the quarter-mile in 12.5 seconds at 114 mph, the quickest figures in the available data. All tested versions in this set use the same 493-hp supercharged V8 architecture, so the spread comes from trim and tune rather than any broader engine transition.
Today, the tested SL55 AMG remains represented here by that early R230 period alone, with a 4.47-second average 0-60 and a 12.93-second average quarter-mile. Within this dataset, the 2004 Kleemann 55K3 Roadster stands as the current high-water mark.

How we verify Mercedes-Benz SL55 AMG performance data
Records and averages on this page cover verified production runs only; modified and prototype results are listed by year but never folded into them. We include only independently published road-test results from automotive publications. Manufacturer-claimed 0–60 times are excluded unless clearly labeled. When multiple publications test the same Mercedes-Benz SL55 AMG trim, each run is listed separately — weather, tires, surface, rollout, and instrumentation all affect results.

Mercedes-Benz SL55 AMG performance FAQs
10 questions The quickest 2004 SL55 AMG run on record is the Kleemann 55K3 Roadster at 4.1 seconds from 0-60 mph. That car is heavily modified, with 493 hp and 575 lb-ft from a supercharged M113K V8. It also ran the quarter-mile in 12.5 seconds at 114 mph.
The fastest SL55 AMG on record is the 2004 Kleemann 55K3 Roadster. It reaches 60 mph in 4.1 seconds and covers the quarter-mile in 12.5 seconds at 114 mph. That result is from a heavily modified car, making it the quickest overall SL55 AMG test rather than the quickest stock example.
The quickest stock SL55 AMG on record is a 2003 Roadster at 4.5 seconds from 0-60 mph. Across 3 total SL55 AMG tests, all-stock and modified combined average 4.47 seconds to 60 mph. For stock-only context, every production SL55 AMG test here is included in that same 3-test total.
The standard Roadster trim has been tested twice, with a 4.65-second average from 0-60 mph and a best run of 4.5 seconds. The slowest recorded Roadster run is 4.8 seconds. That places the regular Roadster slightly behind the heavily modified Kleemann 55K3 version in straight-line acceleration.
The R230-generation SL55 AMG, sold from 2003 to 2008, averages 4.47 seconds from 0-60 mph across 3 tests. The quickest R230 run is the 2004 Kleemann 55K3 Roadster at 4.1 seconds. Across this generation, recorded power is 493 hp, and all tested examples are supercharged gasoline cars.
The fastest R230 SL55 AMG on record is the 2004 Kleemann 55K3 Roadster. It posts a 4.1-second 0-60 mph time and a 12.5-second quarter-mile at 114 mph. Because that car is heavily modified, it stands as the quickest overall R230 SL55 AMG rather than the fastest stock R230 example.
A 2003 SL55 AMG Roadster has recorded 0-60 mph times of 4.5 seconds and 4.8 seconds. The 4.5-second result is the quickest stock SL55 AMG run on record, while 4.8 seconds is the slowest SL55 AMG test overall. Both of those runs come from the R230-generation Roadster.
The Kleemann 55K3 Roadster is quicker. It reaches 60 mph in 4.1 seconds, while the standard Roadster averages 4.65 seconds and has a best recorded run of 4.5 seconds. The gap is clear, but the Kleemann result comes from a heavily modified car, not a stock-production SL55 AMG.
Across all 3 SL55 AMG tests, the average quarter-mile is 12.93 seconds at 110.7 mph. The quickest quarter-mile on record is the 2004 Kleemann 55K3 Roadster at 12.5 seconds and 114 mph. That makes it both the fastest 0-60 SL55 AMG and the quickest quarter-mile SL55 AMG tested.
There are 3 Mercedes-Benz SL55 AMG tests on record, and they average 4.47 seconds from 0-60 mph. All 3 also count as production tests in the page totals, while the quickest overall run is the 4.1-second Kleemann 55K3 Roadster. Quarter-mile average across those 3 tests is 12.93 seconds at 110.7 mph.
