Mercedes introduced the new SL-Class in 2021. It still has a small two-seater with lots of power under the hood, with a retractable soft-top roof. But how does it compare to the SL tuned almost 20 years ago? A new video from Carwow answers that question by racing them.
Powering the 2004 SL55 R230 is a supercharged 5.5 liter V8 engine. It produces 493 horsepower (361 kilowatts) and 516 pound-feet (700 Newton-meters) of torque from the factory. However, the owner sets this example to 625 hp (459 kW). Power is sent via a five-speed automatic transmission to the rear wheels, and it weighs 4,155 pounds (1,885 kilograms).

The new R232 SL55 produces far less power, producing 476 hp (350 kW), but the same amount of torque. The new SL is also heavier, at 4,299 lbs (1,950 kg). However, its nine-speed automatic transmission with launch control and all-wheel drive provided a clear advantage, evident in the first laps at the airfield.
The newer AMG SL55 skyrocketed, leaving its older self struggling for traction early in the race. Once the 2004 SL got going though, it held steady with the newer convertible. However, it was too far behind to close the gap. The new SL completed the quarter mile in 11.5 seconds, while the old took 12.3 seconds.
The 2004 SL performed better in rolling races, nearly beating the newer model in the first fight. It lost the second but won the third by starting in second gear. The new SL stood no chance, falling behind in the half mile race with the older one succumbing at the end. The final brake test of 70 miles per hour (112 kilometers per hour) was conducted on the new car, showing how much brake technology has improved after nearly two decades.
Consumers aren’t flocking to sports cars like they used to, spending money on more useful vehicles like crossovers and SUVs. The SL has been a Mercedes staple since the 1950s, and the latest iteration continues to carry that torch.
