LEXUS LX 600

The 2024 Lexus LX 600 for Japan is a full‑size, body‑on‑frame luxury SUV on the TNGA‑F platform, built in Japan and positioned as Lexus’s flagship off‑roader with a single powertrain: the V35A‑FTS 3.4L V6 twin‑turbo and Direct Shift‑10AT full‑time 4WD. It is offered in five JDM grades: Standard 5‑seat, Standard 7‑seat, OVERTRAIL+ 5‑seat, OVERTRAIL+ 7‑seat, and the chauffeur‑oriented EXECUTIVE 4‑seat, with grade‑specific suspension (KDSS vs E‑KDSS), wheels/tyres, interior layouts, and equipment.

Variants

All JDM LX 600 grades share the same basic powertrain: V35A‑FTS 3.445 L twin‑turbo V6, Direct Shift‑10AT automatic, and full‑time 4WD with low range.

\*Curb weights are JDM‑typical approximations, aligned with global LX 600 figures; Lexus quotes ~6,000 lb for a well‑equipped LX 600.

OVERTRAIL+ Grade Details (5‑ and 7‑seat)

The OVERTRAIL+ grades are JDM‑exclusive off‑road–themed models positioned as the most capable LX 600 variants in rough terrain, replacing the role of “trail‑focused” trims seen in other markets.

Key mechanical differences

• E‑KDSS (Electronic KDSS)
• Actively controls front and rear stabilizer bars via electronically managed hydraulic circuits.
• Enables greater wheel articulation than KDSS in severe off‑road conditions while still maintaining roll control on pavement.
• Wheels & tyres
• 18‑inch off‑road alloys with 265/65R18 all‑terrain tyres, providing
• Larger sidewalls for better impact absorption.
• Increased off‑road grip and durability compared to 22‑inch highway‑terrain tyres.
• Ride height & protection
• Effective ground clearance ~200 mm, tuned for off‑road stability.
• Additional skid plates and under‑body protection for engine, transmission, and fuel tank.
• Off‑road‑tuned AVS damping and traction control thresholds.

Exterior & badging

• Distinctive OVERTRAIL treatment
• Dark‑accent front grille and mirror caps.
• Specific OVERTRAIL badging on front fenders and/or tailgate.
• Unique wheel design and, often, exclusive Nori Green Pearl or earthy tone colorways.
• Black roof rails and rugged body side moldings.

Interior & features

• Seats & materials
• Leather or leather‑like materials with unique stitching and color accents tailored to an outdoor/adventure theme.
• Heavy‑duty floor mats and cargo mat, more resistant to mud and water.
• Technology
• Same dual‑screen infotainment as other grades, but with
• Emphasis on Multi‑Terrain Monitor and off‑road camera views.
• Dedicated OFF ROAD menus showing pitch/roll, steering angle, wheel articulation.
• Seating layouts
• OVERTRAIL+ 5‑seat: 2+3 for maximum cargo space and gear carrying.
• OVERTRAIL+ 7‑seat: 2+3+2 for families who need three rows but still want off‑road capability.

Off‑road systems emphasis

• Crawl Control, Multi‑Terrain Select, DAC, and low range are integral to OVERTRAIL+ positioning, with more aggressive calibration than comfort‑oriented grades.
• Specific traction settings for rock, sand, mud, etc., are standard focus features.

These OVERTRAIL+ models are the most adventure‑oriented LX 600 variants in the JDM lineup, trading the EXECUTIVE’s maximum luxury for increased robustness, off‑road agility, and environmental versatility.
