Design & Presence

The Mercedes SL Class cuts a classic roadster silhouette with a long bonnet, short rear overhang and a broad stance that measures roughly 4.7 metres long and 1.92 metres across, so it reads as a proper grand tourer the moment it appears. Curb weights from about 1,810 to 2,195 kg give the SL a substantial, planted look that suits both a sporty AMG and the more stately Maybach variants. Details such as tight panel gaps, crisply creased surfaces and muscular wheel arches signal luxury without shouting, and the range — from the MHEV SL 43 through the fire-breathing AMG and the Maybach SL 680 — means visual character can swing from athletic to opulent without changing the silhouette.

Interior & Usability

The cabin is unmistakably Mercedes: high-quality materials, precise switchgear and a driver-focused ergonomics layout centered on a large, curved display and tactile controls for the essentials. Front seats are plush and supportive with available climate and massage functions, while rear seats exist but are clearly intended for occasional use or children rather than full-size adults. Practical touches like a usable centre console, wireless charging and a generally quiet environment on the motorway make the SL feel like a comfortable long-distance companion rather than just a weekend toy.

Space & Everyday Practicality

Despite being a 2+2 roadster the SL offers usable trunk space for city life and short trips, with typical luggage capacity around 213 litres and some variants seeing less when the roof is stowed — expect roughly 110 litres in the tightest configurations, which limits big suitcases. Seating for four is real on paper but rear passengers will prefer short hops or child seats; front occupants get the space and adjustability for taller drivers. A 70-litre fuel tank complements long-distance touring, but packing for two with the roof down requires planning rather than optimism.

Driving & Handling

The SL lineup spans a wide performance ladder: the MHEV SL 43 produces about 381 hp and accelerates briskly, mid-range AMGs push into the 476–585 hp territory with 0–100 km/h times in the high 3s to mid 4s, and the SL 63 S E PERFORMANCE plug‑in hybrid peaks at roughly 816 hp and the sharpest sprint figures. Rear‑wheel drive on the lighter models keeps steering lively, while the all‑wheel drive AMGs add traction and confidence in wet conditions; the trade-off is added mass, which the adaptive suspension works hard to hide. In everyday use the SL behaves as a composed cruiser for relaxed highways but can be surprisingly quick and communicative when the road narrows — the AMG versions turn it into a proper performance car for spirited driving.

Efficiency/Consumption & Range

Fuel consumption is characteristic of a luxury performance roadster: the MHEV returns around 9 L/100 km in mixed driving, while V8 AMGs sit closer to 12.9–13.6 L/100 km under typical conditions and the PHEV claims a combined figure near 10 L/100 km with an electric assist and an electric range of only about 12 km. Those numbers mean the SL is most economical on long motorway runs where cruising pays dividends, but city and enthusiastic driving will push consumption higher quickly. The 70-litre tank gives respectable real-world range for touring, though the small PHEV electric range buys only a few zero‑emission city kilometres before the petrol engine takes over.

Assistance & Infotainment

Infotainment is built around Mercedes’ latest MBUX software with large, high-resolution screens and voice control that responds to natural prompts, making common tasks like navigation and media simple on the move. Advanced driver assistance packages include adaptive cruise, lane-keep and semi-autonomous functions that assist on highways but still require driver attention; parking aids and 360‑degree cameras make tight spaces manageable despite the SL’s footprint. The system integrates convenience and safety well, though it’s the tactile comfort items and sound insulation that most owners will notice day-to-day.

Who is it for?

The Mercedes SL suits buyers after a luxurious, high-tech grand tourer that can double as a weekend sports car: choose the SL 43 for refined performance and better economy, an AMG SL 55 or SL 63 for full-bore excitement, the PHEV SL 63 S for extreme performance with short electric assist, or the Maybach SL 680 for maximum comfort and exclusivity. It is not the best solution for those needing family practicality or genuine electric-only range, but for affluent drivers who prioritise style, motorway comfort and a powerful engine soundtrack, the SL remains a compelling, status-rich choice.
