2025 Mercedes-AMG SL 63 S E Performance: A Tamed Version of the GT 63 S E Performance
The 2025 Mercedes-AMG SL 63 S E Performance is a convertible that shares many similarities with its famed sibling, the GT 63 S E Performance. Both cars boast the same powertrain, featuring a 4.0-liter twin-turbo V8 engine, nine-speed automatic transmission, 4Matic+ all-wheel drive, a rear-mounted motor powered by a 6.1-kilowatt battery pack, and a two-speed rear gearbox. With 805 horsepower and 1,047 pound-feet of torque, the SL 63 S E Performance is only a fraction slower than the GT version, taking just 2.8 seconds to reach 60 mph and topping out at 196 mph. Furthermore, the two vehicles have similar dimensions, including width, wheelbase, and interior layout. Rear axle steering, carbon ceramic brakes, and the Active Ride Control suspension feature as standard in both models. The SL differentiates itself with a convertible design, a unique front fascia, and a center screen that tilts to reduce glare when the top is down.
One notable distinction between the SL 63 S E Performance and the GT 63 S E Performance lies in their suspension tuning. The SL’s Active Ride Control suspension offers a slightly softer ride compared to the GT’s setup, contributing to a more relaxed driving experience. This alteration sacrifices a bit of responsiveness but makes up for it by reducing harshness. The SL’s steering, which has been criticized for feeling disconnected, becomes more forgivable in light of this character shift.
However, despite its similarities and subtle distinctions, the SL 63 S E Performance raises some concerns. With its monstrous power output, the 805-hp S E Performance variant may be perceived as excessive and lacking in practicality. The non-hybrid SL 63 already offers an impressive 577 horsepower, more than enough power for most drivers. The addition of an electric motor seems unnecessary, as the enjoyment of a growling V8 engine with the top down remains virtually unchanged. Furthermore, the limited electric range of just 8 miles in European testing renders the electric feature almost pointless for anything other than short weekend drives. Mercedes could have better prioritized range and capacity, making a fully electric SL a more appealing prospect.
Nevertheless, the SL 63 S E Performance does have its strengths. The serene experience of peaceful, top-down cruising and the ability to toodle around with the silent, 200-horsepower electric motor provide enjoyable moments. However, the short electric range quickly becomes a limitation. In no time, the battery drains, necessitating the use of the powerful V8 engine to recharge. This raises questions about the practicality and purpose of the powertrain configuration in the SL.
One key aspect that sets the SL apart from the GT is its price. The base price for the SL 63 S E Performance starts at $208,150, offering a significant power increase compared to its predecessors at a reasonable price per horsepower. For those seeking the ultimate SL experience, the S E Performance variant is the obvious choice. However, it must be acknowledged that its electric benefits are minimal, leaving potential buyers with a conflicted decision.
In conclusion, while the 2025 Mercedes-AMG SL 63 S E Performance provides a beautiful, comfortable, and fast driving experience, the extent of its electrification and the practicality of its added features remain in question. It seems that Mercedes could have better optimized the electric capabilities, focusing on range and capacity rather than emphasizing rapid discharging and power. As a result, the SL 63 S E Performance falls short of its potential.
