<p>The 2026 Mercedes-AMG SL is an impressive luxury roadster with a glorious heritage.</p>


Cons

Power, Ride and Handling

Driving Impressions

<p>Drivetrains in the 2026 AMG SL go from great to good gracious. The SL 43 flexes its 416 horsepower to sprint from standstill to 60 mph in a perfectly zippy 4.8 seconds. Most SL buyers don’t need to go faster than this. But the ones who do can put the SL 55’s 469 horsepower to the ground and hit 60 mph a second sooner. Or shave off another 0.3 of a second in the 577-horsepower SL 63.</p>
<p>To compare with the SL 43, the “base” Porsche 911 Carrera Cabriolet has 379 horsepower and is about half a second quicker to 60 mph, while the Mercedes beats the BMW 840i Convertible by a small margin. Anyway, it isn’t all about the numbers with an SL.</p>
<p>Although there is another twist with the AMG SL 63 S E Performance, which harnesses electric power as well as combustion to push the SL to extremes it’s never known before. It develops a truly awesome 805 horsepower and up to 1,047 lb-ft of torque. The 60-mph mark is but a fleeting event that happens just 2.8 seconds (gasp) into its rush to a top speed of 198 mph.</p>
<p>In general, we’ve found the SL does a fantastic job of balancing engaging performance with a luxurious ride quality. We could cruise for hours on the highway with no complaints. Yet the SL is equally in its element on twisting back roads, thanks to the all-wheel steering system (in the V8-powered models) and the well-tuned AMG Ride Control suspension system.</p>
<h3>Fuel Economy</h3>
<p>It’s unlikely that SL buyers will care too much about gas bills. That said, the SL 43 achieves 22 mpg in combined city/highway driving. Which is fine, we suppose. The BMW 840i Convertible gets 24 mpg combined, about as good as this class gets. The SL 55 and SL 63 both run to 16 mpg combined. The SL 63 S E Performance achieves the equivalent of 29 mpg combined (MPGe) or 18 mpg combined once the battery is depleted. Its battery-only range is negligible.</p>


Athletic Exterior

Exterior

<p>We’d say the Mercedes-AMG SL is handsome. It looks simultaneously expensive and athletic, with sports-car proportions and stylish wheel options. This current SL forgoes the retractable hardtop of previous SL generations in favor of a powered soft top. We think it looks great with the roof down.</p>
<p>This year, the Manufaktur program adds Ireland Mid-Green Magno (not mango), Cote d’Azur light blue, and Orange Flame Metallic. And then there’s the impressive list of Manufaktur Exclusive finishes.</p>
