AMG's first ground-up supercar — gullwing doors, a naturally aspirated 6.2-litre V8 and the spiritual successor to the 300 SL.
Unveiled at Frankfurt in 2009 and on sale from 2010 to 2014, the SLS AMG was the first car designed, engineered and built in-house by Mercedes-AMG from the ground up. Built on an aluminium spaceframe and powered by the hand-assembled M159 6.2-litre naturally aspirated V8 producing 563 hp, it paired front-mid engine, rear-transaxle layout with a Getrag dual-clutch seven-speed gearbox — and revived the gullwing-door silhouette of the 1954 300 SL for the modern era.
The range expanded over four years to include the Roadster (2011), the rear-drive electric SLS AMG Electric Drive (2013, the most powerful electric car of its era at launch), the track-focused GT and Final Edition variants, and the limited-production Black Series (2013) with 622 hp and significant aerodynamic and chassis revisions. Roughly 8,000 SLS AMGs were built across all variants. The model also formed the basis of the SLS AMG GT3 customer racing car, which became one of the most successful GT3 platforms of the 2010s.
The SLS AMG is the last naturally aspirated front-engined Mercedes-AMG supercar and the only modern road car to revive the gullwing doors of the 300 SL. The M159 V8 is one of the great naturally aspirated engines of its generation, hand-built under the 'one man, one engine' AMG philosophy, and the SLS established the template for the AMG GT that followed. The Black Series is already recognised as a blue-chip modern collector car, and the manual-shift dynamics, transaxle layout and naturally aspirated character of the standard car distinguish it sharply from the turbocharged supercars that succeeded it.
| Variant | Years | Production | Notes |
|---|---|---|---|
| SLS AMG Coupe (Gullwing) | 2010–2014 | — | Original 563 hp gullwing coupé; the design icon and volume car. |
| SLS AMG Roadster | 2011–2014 | — | Conventional doors and power soft-top; same 563 hp drivetrain; structurally reinforced. |
| SLS AMG GT (Coupe & Roadster) | 2012–2014 | — | 591 hp, faster shift programming, revised damper tune; the better-developed standard car. |
| SLS AMG Black Series | 2013–2014 | — | 622 hp, dry-sump M159, carbon-fibre body panels, fixed rear wing; approximately 132 UK / circa 1,000+ worldwide; the collector halo. |
| SLS AMG GT Final Edition | 2014 | — | Limited run-out specification with carbon detailing and Black Series-derived aerodynamic elements; 350 units. |
| SLS AMG Electric Drive | 2013–2014 | — | All-electric, four-motor, approx. 750 hp; produced in very limited numbers; technically significant but a niche market. |
| SLS AMG GT3 (racing) | 2011–2020s | — | Customer GT3 racing car; widely campaigned globally; referenced for pedigree, not road-market comparables. |
An SLS is bought on its service history. Look for continuous Mercedes-Benz / AMG main-dealer or recognised independent specialist servicing, annual oil services regardless of mileage, both keys, original books, the toolkit and any documented warranty work. Cars with full Mercedes-Benz history and a clear ownership chain command meaningful premiums; cars with patchy history or non-specialist service should be priced accordingly.
The GT is the better-developed standard car — sharper shift programming, revised damper tune and 591 hp — and represents the strongest mainstream proposition. Original 563 hp coupés in sought-after colours (Iridium Silver, Obsidian Black, AMG Le Mans Red, Designo Mystic White) remain the design statement. The Black Series operates in its own band as a blue-chip limited-production halo and behaves more like a 458 Speciale or 911 GT3 RS in pricing dynamics. Roadsters are best chosen on condition rather than as an investment.
The Getrag DCT rear transaxle is generally robust but is a known service item; verify the date of the last DCT fluid service (typically every 40,000 miles or earlier on track-used cars) and listen for clunking from the propshaft and driveshaft at low speeds, which can indicate worn centre bearings or CV joints. Track-used cars — particularly those with documented circuit use or aftermarket exhausts — should be priced to reflect more frequent transaxle and clutch service.
The aluminium spaceframe and panels are expensive to repair correctly. Inspect panel gaps, the operation of the gullwing doors (including the pyrotechnic release mechanism's service interval, which Mercedes specifies on a time basis), and the front splitter and underbody for evidence of kerbing. Budget £800–£1,500 for a PPI at a recognised AMG specialist; the inspection should include a full diagnostic scan, fluid analysis and a documented underbody check.

The hand-built M159 V8 is a robust, long-lived engine with no widely reported systemic issues when serviced on schedule. Cars that have been serviced annually at AMG or recognised specialists routinely cover six-figure mileage without major work. The cost focus on an SLS is the dual-clutch transaxle, carbon-ceramic brakes (where fitted) and tyres, not the engine.
Many SLS AMGs were specified with optional carbon-ceramic brakes; replacement discs are a significant cost and any signs of cracking or excessive wear should be priced into the purchase. Original-fit Continental tyres and replacement sets are expensive, and any track use should prompt closer inspection of brakes, tyres and transaxle.

The SLS AMG market softened in the second half of the 2010s as the model moved through its initial depreciation cycle, but stabilised from around 2021 as collectors recognised it as the last naturally aspirated front-engined AMG supercar and the only modern revival of the gullwing silhouette. The GT and GT Final Edition have re-rated most clearly, supported by their improved dynamics and limited production, and the Black Series has established itself as a blue-chip modern collector car alongside the 911 GT3 RS 4.0 and the 458 Speciale.
Within the range, gullwing coupés in original specification and sought-after colours sit at a clear premium to roadsters, which trade more as usable open supercars. Documentation — particularly full Mercedes-Benz / AMG service history and verifiable absence of significant track use — is the deciding factor at every tier. Cars with bills from a recognised AMG specialist and a clean accident record sell readily; cars with patchy history or non-specialist modifications are increasingly difficult to move at strong money.

The SLS AMG occupies a clearly defensible position as the last naturally aspirated, front-engined AMG supercar and the only modern revival of the gullwing-door silhouette. Production is closed, the model is supported globally by Mercedes-Benz and an active independent specialist network, and the long-term narrative is well established.
Within the range, the GT, GT Final Edition and Black Series offer the strongest risk-adjusted outlook. The Black Series is already a blue-chip modern collector car. Original-specification gullwing coupés in sought-after colours with full Mercedes-Benz history will continue to appreciate steadily. Cars without documented service history, with significant track use, or with non-reversible modifications should be priced as drivers rather than collectibles.
