Design Evolution & Exterior Details
The G‑Class silhouette has been virtually unchanged since 1979, a rarity in an industry that reshapes bodies every cycle. The 2019 refresh added adaptive LED headlamps, a wider AMG‑specific grille with vertical slats, and standard black‑out trim that gives the G63 a more menacing stance. Portal axles — unique to the G‑Class — lift the body above the wheel centers, delivering the 10.4‑inch clearance without a traditional lift kit.

Practical touches include 19‑inch forged AMG wheels (many owners step up to 22‑inch aftermarket sets), quad‑exit performance exhaust, and optional carbon‑fiber exterior accents. If you plan regular trail use, consider adding rock sliders and a front brush guard; they protect the chassis during low‑speed impacts and preserve resale appeal.

Powertrain & Performance
At the heart of the G63 sits the hand‑built M177 4.0‑liter V8 with twin‑scroll turbos, dry‑sump lubrication, and a 10.5:1 compression ratio. The engine produces 577 hp and 627 lb‑ft of torque across a broad 2,500‑5,000 rpm band, enabling a 0‑60 mph sprint in 4.5 seconds despite the vehicle’s 5,200‑lb mass. Power routes through the 9G‑TRONIC nine‑speed automatic, which features short first‑gear ratios for low‑speed crawling and tall overdrive gears for highway cruising.

Driving dynamics are managed by AMG DYNAMIC SELECT with five core modes (Slippery, Comfort, Sport, Sport+, Individual) plus dedicated off‑road programs: Sand, Trail, and Rock. In Rock mode the center and rear differentials lock automatically, throttle response is softened, and the low‑range transfer case engages for maximum torque multiplication. On pavement the adaptive damping (AMG Ride Control) firms up under hard cornering yet remains compliant over broken surfaces — though wind noise at 70 mph is noticeable due to the upright greenhouse.
Drivetrain, Off‑Road Hardware & Driving Modes
The 4MATIC+ system splits torque 40:60 front‑to‑rear under normal conditions but can send up to 100 % to either axle when a lock is engaged. Three electronically controlled differential locks — center, rear, and a virtual front lock via brake‑based torque vectoring — give the G63 genuine rock‑crawling credibility. Ground clearance, approach/departure angles, and a 31.5‑inch wading depth exceed many purpose‑built off‑roaders.
Key off‑road aids:
- Low‑range gearing (2.31:1 reduction) for controlled descents.
- Crawl Control (off‑road cruise) maintains 1‑5 km/h without pedal input.
- Off‑road screen in the instrument cluster displays pitch, roll, steering angle, and diff‑lock status.
- Portal‑axle service intervals every 30,000 mi (oil change) — a cost often overlooked by new owners.
In practice, the G63 can negotiate Moab’s Hell’s Revenge trail on stock tires, though many enthusiasts fit 35‑inch all‑terrains and a modest 2‑inch lift for extra margin.
Interior, Comfort & MBUX Technology
Step inside and the contrast between rugged exterior and opulent cabin is immediate. Standard equipment includes Nappa leather upholstery, heated/ventilated front seats with memory, a panoramic sunroof, and dual 12.3‑inch widescreen displays running the second‑generation MBUX system. Voice control (“Hey Mercedes”) handles navigation, climate, and media; wireless Apple CarPlay/Android Auto and a 4G LTE hotspot keep passengers connected.
Optional upgrades that matter:
- Burmester 3D surround sound (15 speakers, 590 W) — transforms the cabin into a concert hall.
- AMG Performance seats with deeper bolsters and integrated headrests.
- Carbon‑fiber or open‑pore wood trim packages.
- Rear‑seat entertainment (dual 10.1‑inch screens) for family duty.
Rear legroom is generous (38.6 in), but the optional third row is tight — suitable only for children on short hops. Cargo volume behind the second row measures 38.1 cu ft; folding both rows expands it to 68.6 cu ft, enough for a week’s camping gear.
Safety & Driver‑Assistance Features
Every 2019 G63 ships with the Driving Assistance Package, which bundles:
- Adaptive cruise control with stop‑and‑go
- Active Brake Assist with cross‑traffic detection
- Blind Spot Assist and Exit Warning
- Active Lane Keeping Assist
- PRE‑SAFE® Sound (pre‑crash hearing protection)
- Traffic Sign Assist
The NHTSA awarded the G‑Class a 5‑star overall rating; the IIHS gave “Good” scores in all crashworthiness categories. For the latest safety bulletins, consult the NHTSA safety ratings database.
Ownership Costs: Fuel, Maintenance & Insurance (2026 Figures)
| Cost Item | 2026 Estimate (USD) |
|---|---|
| Annual fuel (15,000 mi @ 13 mpg, $3.80/gal) | $4,380 |
| Scheduled maintenance (incl. portal‑axle oil, brake fluid, spark plugs) | $1,800‑$2,400 |
| Extended warranty (3 yr/36 k mi, third‑party) | $3,500‑$5,000 |
| Insurance (full coverage, 40‑yr‑old driver, clean record) | $2,800‑$3,500 |
| Depreciation (first 5 yr, avg.) | ~45 % |
The G63 demands premium unleaded (91 octane minimum). Mercedes‑Benz explicitly states that lower octane can cause knock and long‑term damage; see the premium fuel requirements and model‑specific fuel guide for details. Some owners experiment with 89 octane in cool weather, but the regular vs premium trade‑offs generally favor sticking to spec.
Real‑World Reliability & Common Issues
Overall reliability is above average for a high‑performance luxury SUV, provided service intervals are respected. Frequently reported items (based on owner forums and dealer bulletins):
- Turbocharger wastegate rattle — usually appears after 60 k mi; covered under extended warranty if caught early.
- Portal‑axle seal weep — minor oil seepage; corrected by updated seal kit (TSB 2021‑045).
- MBUX screen delamination — early production units; resolved by software update 2020‑07.
- Air‑suspension compressor wear — more common on vehicles frequently driven in “Sport+” mode.
A pre‑purchase inspection by a Mercedes‑specialist shop (focus on turbo health, portal‑axle oil condition, and MBUX screen integrity) is strongly advised.
Buying a Used 2019 G63: Checklist & Market Prices (2026)
| Mileage Band | Typical Private‑Party Price (USD) | Dealer CPO Price (USD) |
|---|---|---|
| < 20 k mi | $135 k‑$150 k | $150 k‑$165 k |
| 20‑40 k mi | $120 k‑$135 k | $135 k‑$150 k |
| 40‑60 k mi | $105 k‑$120 k | $120 k‑$135 k |
| > 60 k mi | $90 k‑$105 k | $105 k‑$120 k |
Buyer’s checklist
- Verify complete service records (especially portal‑axle oil changes every 30 k mi).
- Confirm all three differential locks engage/disengage cleanly via the off‑road menu.
- Inspect turbo wastegate actuators for play; listen for rattle on cold start.
- Check MBUX screen for bubbles or yellowing — early units were replaced under goodwill.
- Ensure original window sticker (Monroney) matches equipment; many G63s receive aftermarket wraps that hide paint defects.
- Obtain a vehicle‑history report; look for accident repairs on the aluminum‑intensive body structure.

Frequently Asked Questions
What distinguishes the G63 from the standard G‑Class?
The G63 receives the hand‑built twin‑turbo V8, AMG‑tuned suspension, specific styling (grille, exhaust, wheels), and the full Driving Assistance Package as standard. The base G‑Class (G550) uses a 4.0 L V8 with 416 hp and softer suspension tuning.
How many miles are typical for a 2019 model today?
Most examples show 25,000‑55,000 mi. Low‑mileage (< 15 k) units command a premium; well‑maintained higher‑mileage trucks (> 70 k) can still be solid if portal‑axle service is documented.
Is the third‑row seat practical?
Only for occasional child use. Adult headroom is 35.2 in and legroom 28.4 in — tighter than a compact sedan’s rear seat.
What is the real‑world towing experience?
Owners report stable pulling up to 6,500 lb with a properly equipped trailer brake controller. The 7,000‑lb rating is achievable but requires a weight‑distribution hitch and careful tongue‑weight management.
Should I buy new (remaining inventory) or used?
New old‑stock units are virtually gone; a certified pre‑owned example with remaining factory warranty offers the best value. Verify the CPO inspection covers portal‑axle seals and turbo wastegates.
Can I modify the G63 for more off‑road capability?
Yes — popular upgrades include 2‑inch lift kits, 35‑inch all‑terrain tires, skid plates, and heavy‑duty control arms. Keep receipts; excessive lifts (> 3 in) may void the remaining drivetrain warranty and hurt resale. For alternative fuel considerations after modifications, review alternative fuel options.
Conclusion
The 2019 Mercedes‑AMG G63 endures as a singular vehicle — part military‑grade off‑roader, part rolling boutique hotel, part supercar. Its portal axles, triple locking diffs, and 577‑hp V8 create a capability envelope that few can match, while the MBUX cabin and Burmester audio deliver daily‑driver civility. Ownership demands a budget for premium fuel, specialized maintenance, and higher insurance, but resale strength softens the long‑term cost. If you want a luxury SUV that can genuinely tackle the Rubicon Trail on Saturday and valet at a five‑star hotel on Sunday, the G63 remains the benchmark.
