01 / This trim
What makes this trim its own car
Position in the lineup
Range-topping flagship
- Most power in the lineup: 470 hp.
- Quickest 0–60 of any trim at 4.5s.
- Highest top speed of the range — 110 mph.
- Most expensive trim — $100K as tested.
Ideal buyer
Who this trim is for
Buyers who want the definitive version. You're paying for the last 5% of capability — the bigger brakes, the lighter wheels, the more aggressive suspension, and the bragging rights. If a spec sheet is going to live on your wall, this is the trim that earns it.
Probably not for
Daily commuters and value hunters — most of the headline upgrades only show up at the limit, and depreciation on a top-trim is steeper than the trims below it.

04 / Maintenance
Keep it running for the long haul
Body-on-frame trucks and SUVs like the Wrangler Rubicon 392 live on the severe-duty schedule. Driveline service (transfer case, diffs, transmission) is the #1 longevity factor — these components see constant load even on pavement.
Break-in (first 1,000–1,500 mi)
Most powertrain damage happens here. Do these right and the car will outlive its electronics.
- First 600 mi: keep RPM below 4,000 and avoid full-throttle pulls. Vary RPM constantly — no cruise control.
- Avoid highway-speed cruise for >30 min stretches; varied load helps the rings seat properly.
- Do NOT change the factory-fill oil before 1,500 mi unless the manufacturer specifies otherwise — the oil contains break-in additives.
- At 1,500–3,000 mi, perform the first oil change to remove metal break-in particles from ring/bearing seating.
| Interval | Task | Why it matters | Priority |
|---|---|---|---|
| Weekly | Cold tire pressure check | Set to door-jamb spec when tires are cold. Underinflation kills sidewalls and fuel/range economy; overinflation reduces grip. | High |
| Weekly | Visual walk-around | Check for fluid spots on the ground, tire condition, light operation, and any new noises before driving off. | Recommended |
| Monthly | Fluid level audit | Open the hood: check engine oil (where dipstick exists), coolant overflow level, brake fluid, washer fluid, power steering (if hydraulic). | High |
| Monthly | Wash + interior vacuum | Salt, road tar and bird droppings etch paint and clearcoat. Use pH-neutral car shampoo, two-bucket method. | Recommended |
| Every 6 months | Wax / ceramic top-up | Paint protection prevents oxidation. Spray-on ceramic boosters extend a base coat for 6–9 months. | Recommended |
| Every 12 months | Wiper blades + washer fluid | Replace both blades; switch to winter blades + de-icer fluid in cold climates. | Recommended |
| Every 12 months | 12V auxiliary battery test | Load-test the 12V battery — even EVs have one, and a weak 12V causes the most no-starts on modern cars. | High |
| Every 24 months | Brake fluid moisture test | Test with a refractometer or strips. >2% water content = flush. Hygroscopic fluid corrodes ABS modulators. | Critical |
| Every 24 months | Alignment check | Even a curb hit can throw alignment off. Mis-alignment burns through $1k+ tire sets quickly. | High |
| Every 7,500 mi / 12 months | Full-synthetic oil + filter change | Modern long-life synthetic at OEM spec. Don't stretch past the time interval even if low mileage — oil degrades by age too. | Critical |
| Every 30,000–60,000 mi | Coolant level + condition check | Use only the OEM-spec coolant (manufacturer-spec long-life). Mixing coolant types causes gelling and water-pump failure. | High |
| Every 60,000 mi | Coolant flush + refill | Long-life ≠ lifetime. Old coolant turns acidic and eats aluminum heads. | High |
| Every 15,000 mi | Engine air filter + cabin filter | Restricted intake hurts power and economy. Replace cabin filter sooner in pollen-heavy or urban areas. | Recommended |
| Every 60,000–100,000 mi | Iridium / platinum spark plugs | Modern long-life plugs; replace as a complete set with anti-seize. | High |
| Every 100,000 mi | Timing chain / belt service | Most modern engines use chains (inspect tensioner & guides); some Audi 2.0/3.0 TDI/TFSI use a belt that MUST be replaced on schedule — failure destroys the engine. | Critical |
| Every 12 months | Brake pad/rotor visual + caliper slide service | Lubricate caliper slide pins with high-temp grease. Replace pads at 3 mm; rotors at minimum thickness or when scored. | Critical |
| Every 24 months / 30,000 mi | Brake fluid flush (DOT 4 or higher) | OEM-spec DOT 4 fluid; bleed all four corners, ABS module, and clutch (if hydraulic). | Critical |
| Every 30,000 mi | Suspension bushing + ball-joint inspection | Check control-arm bushings, sway-bar end links, tie-rod ends and ball joints for play. Worn bushings cause clunks and uneven tire wear. | High |
| Every 50,000 mi | Power steering fluid (if hydraulic) | Electric racks are sealed-for-life. Hydraulic systems need a fluid flush to prevent pump whine. | Recommended |
| Every 30,000–50,000 mi | Automatic transmission fluid + pan filter | 'Lifetime' is marketing — fluid breaks down by 60k. Use exact OEM spec (ZF Lifeguard 8 for 8HP, MB 236.15, etc.). Drop-pan service is gentler than a power flush. | High |
| Every 30,000 mi | Front & rear differential oil | AWD components see constant load. Use OEM 75W-90 or 75W-140 gear oil and friction modifier on LSDs. | High |
| Every 30,000 mi | Transfer case fluid | Transfer case fluid is small in volume but high in shear stress. Replace at every diff service. | High |
| Every 30,000 mi | Transfer case + locking-diff actuator service | Real 4WD systems with low range need both fluid changes and electric/vacuum actuator inspection for locking diffs. | Critical |
| After heavy off-road use | Driveline grease + boot inspection | Grease U-joints, CV joints, and slip yokes. Inspect axle boots for tears that let water in. | High |
| Every 7,500 mi | Performance tire rotation + wear-depth audit | Heavy / high-power cars (5,103 lb, 470 hp) shred rear tires fast. Cross-rotate fronts to opposite rear, keep all four within 2/32" depth. | Critical |
| Every 30,000 mi | Solid-axle ball joints + steering damper | Death wobble prevention: tight ball joints, fresh steering damper, correct tire balance. | Critical |
| Before storage (>30 days) | Fuel stabilizer + battery tender + tire pressure +5 psi | Add Sta-Bil to a full tank, hook a smart tender to the 12V (and Level-1 charge any EV/PHEV), inflate tires +5 psi to prevent flat-spotting, leave windows cracked. | High |
| Coming out of storage | Pre-flight inspection | Check tire pressures, brake function (rotors will be surface-rusted — bed gently), fluid levels, and rodent damage in the engine bay and cabin air intake. | High |

Fluid specs
Use only OEM-approved fluids. Wrong fluid = catastrophic gearbox / engine damage.
| Fluid | Spec / Approved Type | Capacity |
|---|---|---|
| Engine oil | 0W-20 / 5W-30 full-synthetic (OEM long-life spec) | ~8–10 qt |
| Coolant | OEM long-life HOAT/OAT — do not mix types | ~2.5–3.5 gal |

| Automatic transmission | OEM Dexron / Mercon / manufacturer-spec ATF | — |
| Differential gear oil | OEM 75W-90 (rear) / 75W-140 (LSD) | — |
| Transfer case fluid | OEM spec — usually a thin ATF-style oil | — |
Longevity tips
- Warm the engine fully (oil at 180°F+) before any spirited driving — cold metal under load wears 10× faster.
- Run the OEM-spec octane — most modern engines tolerate 87 but premium-required engines are non-negotiable.
- After hard driving (track, mountain pass, autobahn pulls), idle 30–60 s before shutdown so turbos cool and oil temps stabilize.
- Store on a battery tender if driven less than once a week — modern ECUs draw heavy parasitic loads.
- Address small issues immediately (squeaks, warning lights, fluid spots) — they compound into $5k+ repairs.
- Keep a written service log — both for your own tracking and resale value (Carfax-style records add 5–10% at sale).
- Use OEM-spec parts and fluids — aftermarket 'equivalents' often aren't, and brand-engineered specs exist for real reasons.
- Replace tires as a complete set (or at minimum same axle) and never mix tire models on an AWD car — damages the center diff.
Brand-specific notes
- Stellantis 8-speed (ZF 8HP) is excellent but needs fluid service at 60k regardless of 'lifetime' label.
- Always cross-reference your VIN with the latest OEM TSBs and recalls — manufacturers fix common issues silently under warranty.
- Use the manufacturer app or a third-party scan tool (BimmerLink, OBDeleven, Techstream, Forscan) to monitor adaptations and clear codes between services.
