The 2013 Mercedes G63 AMG stands as a pivotal model in the G‑Class lineage — the first to wear the AMG‑tuned 5.5 L twin‑turbo V8 (M157) and the last before the platform’s 2019 redesign. It blends military‑grade off‑road hardware with a handcrafted interior, delivering 536 hp and 560 lb‑ft of torque in a shape that hasn’t fundamentally changed since 1979. Whether you’re cross‑shopping a used example or researching the specs that made it a collector favorite, this guide covers every critical detail.

Engine & Performance
5.5 L M157 Twin‑Turbo V8
The heart of the G63 AMG is the hand‑assembled M157 V8. Twin scroll turbos, direct injection, and a 10.0:1 compression ratio produce 536 hp at 5,500 rpm and 560 lb‑ft of torque from 1,750–5,000 rpm. Unlike earlier naturally aspirated AMG V8s, this engine delivers massive low‑end twist — ideal for both rock crawling and highway passing. In practice, throttle response is nearly instantaneous; the turbos spool with minimal lag thanks to the small turbine wheels and equal‑length exhaust manifolds.
Transmission & Driveline
Power routes through the AMG SPEEDSHIFT PLUS 7G‑TRONIC seven‑speed automatic. It features a wet multi‑plate launch clutch (replacing the torque converter) for sharper shifts and a dedicated “M” manual mode with paddle shifters. The permanent 4MATIC all‑wheel‑drive system splits torque 40/60 front/rear under normal conditions but can send up to 100 % to either axle when the three locking differentials are engaged.
Acceleration & Top Speed
- 0–60 mph: 5.3 seconds (manufacturer claim)
- Quarter mile: ~13.8 seconds at 102 mph
- Top speed: 130 mph (electronically limited); 150 mph with the optional AMG Driver’s Package
Off‑Road Capability
The G63 AMG retains the ladder frame, solid axles, and three mechanically locking differentials (center, front, rear) that define the G‑Class. Key numbers:
- Ground clearance: 8.3 in (210 mm)
- Approach / departure / breakover angles: 36° / 27° / 23°
- Wading depth: 23.6 in (600 mm)
- Low‑range reduction: 2.05:1 via a two‑speed transfer case
Locking the diffs is as simple as pressing three dashboard buttons — center first, then front and rear. With all three engaged, each wheel receives equal torque, allowing the G63 to climb near‑vertical rock faces that would stop a conventional SUV. The standard AMG RIDE CONTROL suspension offers two damper settings (Comfort/Sport) but does not adjust ride height; aftermarket lift kits are common among serious off‑roaders.
Exterior Design
Interior dashboard with COMAND screen and Nappa leather seats
The 2013 G63 AMG distinguishes itself from the standard G550 with:
- AMG‑specific front bumper with larger air intakes and integrated LED daytime running lights
- Flared wheel arches covering 20‑inch forged cross‑spoke wheels (275/50 R20 tires)
- “V8 BITURBO” badge on the front fenders
- Side exhaust outlets just ahead of the rear wheels (optional AMG Performance exhaust adds a bypass valve for a louder note)
- Roof rails, spare‑tire carrier, and protective side cladding all standard
The boxy silhouette isn’t just nostalgia — it maximizes interior volume and provides excellent visibility. Paint options included designo magno matte finishes, which require specialized care.
Interior, Comfort & Technology
Cabin Materials & Layout
- Seats: AMG performance front seats with Nappa leather, contrast stitching, heating, ventilation, and 14‑way power adjustment
- Trim: Carbon‑fiber or piano‑lacquer wood inserts (optional)
- Steering wheel: AMG flat‑bottom design with aluminum shift paddles and touch‑sensitive controls
- Rear accommodations: Three‑person bench with 60/40 split folding; headroom generous despite the sloping roofline
Infotainment & Connectivity
The COMAND APS system centers on a 7‑inch color display (non‑touch) controlled via a rotary knob. Features:

- 30 GB music register (hard‑drive)
- Bluetooth audio streaming and phone pairing
- Harman Kardon Logic7® surround sound (standard); Bang & Olufsen BeoSound (optional)
No Apple CarPlay/Android Auto — those arrived with the 2019 NTG5.5 system. DVD map updates are still available from Mercedes but are increasingly rare.
Safety & Driver Assistance
| Feature | Standard / Optional |
|---|---|
| Electronic Stability Program (ESP®) | Standard |
| Adaptive Brake Assist with HOLD function | Standard |
| Six airbags (dual front, side, window) | Standard |
| ATTENTION ASSIST drowsiness monitor | Standard |

The G63 lacks modern active safety suites (automatic emergency braking, adaptive cruise with stop‑and‑go). Retrofitting is limited; buyers should budget for heightened situational awareness.
Fuel Economy & Emissions
The EPA rates the 2013 G63 AMG at 11 mpg city / 15 mpg highway / 12 mpg combined. Real‑world averages typically fall between 9–11 mpg due to the vehicle’s 5,500 lb curb weight, aerodynamic drag (Cd 0.54), and the rich fueling strategy of the M157 under load. Premium unleaded (91 octane minimum) is mandatory — using regular risks detonation and voids warranty coverage. For a deeper dive on fuel requirements across the Mercedes lineup, see the discussion on premium fuel requirements and model‑specific fuel needs. If you’re weighing alternatives, the article on alternative fuel options and the breakdown of regular vs premium trade‑offs provide practical guidance.
The M157 meets Euro 5 / ULEV‑II emissions standards. CO₂ output is 322 g/km (EU cycle). No start‑stop system or cylinder deactivation is fitted.

Pre‑Purchase Inspection Checklist
- Cold‑start video — listen for turbo wastegate rattle or excessive valve‑train noise.
- Oil analysis — detect fuel dilution or bearing wear.
- Differential fluid condition — milky fluid indicates water ingress (common after deep wading).
- Frame inspection — look for rust at the rear crossmember and spring perches.
- Transmission adaptation values — read via XENTRY/STAR diagnostics; high clutch wear indexes signal imminent overhaul.
- Service history verification — confirm all recalls (e.g., fuel‑pump module, seat‑belt pretensioner) were performed.
Pro tip: A Mercedes‑Benz Classic Center or AMG Performance Center inspection adds credibility and may unlock extended warranty eligibility.
Conclusion
The 2013 Mercedes G63 AMG remains a singular proposition: a hand‑built V8 flagship that can summit Moab’s Hell’s Revenge one day and valet at a five‑star hotel the next. Its M157 engine delivers a character that newer electrified AMGs struggle to replicate, while the three‑locker drivetrain provides genuine off‑road credibility. Ownership demands a healthy budget for fuel and specialized maintenance, but well‑sorted examples are appreciating as the last of the “analog” G‑Class AMGs. If you value mechanical purity, iconic design, and a driving experience that borders on theatrical, the 2013 G63 AMG deserves a spot on your shortlist.
