Scania 660S V8 Highline (2026) – Flagship Power with New Kelsa CabBox Custom Rig! | RTX

New Scania 660S V8 Highline (2026) – Epic Kelsa Lightbars & Custom Back-of-Cab CabBox! | RTX Stoneleigh 🔴 Live from Stoneleigh: Custom Rear-Cab Lockerbox Craftsmanship Meets 660HP V8 Swedish Grunt! We are coming to you live from the highly packed, incredibly vibrant custom truck and accessory arena at the Road Transport Expo (RTX) 2026 here at NAEC Stoneleigh Park, UK! While standard fleet-spec distribution rigids and highway box vans occupy the main trade lanes, dedicated owner-drivers, custom transport operators, and hardcore V8 purists are forming a solid wall of gridlock around one of the most stunning custom builds of the year. Say hello to the spectacular, brand-new 2026 Scania 660S V8 Highline custom showstopper! Showcased directly on the prestigious Kelsa Stand (Y36), this premium long-haul masterclass demonstrates exactly how to perfectly fuse legendary V8 pulling power with elite, highly functional custom-fabricated chassis accessories and high-polish stainless steel styling. Dressed in an immaculate custom fleet finish and rolling on mirror-finish Alcoa Dura-Bright alloy wheels, this 660S stands as a total masterpiece of modern truck customization. Up front, the wind-tunnel-optimized Highline cab architecture is heavily upgraded with a full suite of high-mirror-finish Kelsa stainless steel lightbars packed with high-intensity spot lamps that completely slice through dark motorway routes. However, the absolute main attraction sits directly behind the cabin—a beautifully engineered, custom-tooled rear-cab "CabBox" (Lockerbox) utility storage housing system. We take an intensive, highly detailed close-up walkaround of this unique V8 king to evaluate its 16.4-litre heart, inspect the precision of its custom back-of-cab chassis decking, and step inside its ultra-luxurious, flat-floor digital Smart Dash cabin! Key 2026 Specs & Premium Custom Working Features: Savage 660HP King-Tier V8 Powerhouse: Hidden beneath the flat floor of the S-Series cab is Scania's legendary 16.4-liter DC16 V8 engine block. Channeling an incredible 660 horsepower and a massive 3,300 Nm of torque low down at 950 RPM, it hits the absolute sweet spot for heavy bulk distribution—delivering incredible hill-climbing authority under maximum payload weight while providing that deep, rhythmic V8 exhaust note that truck enthusiasts live for. Bespoke Back-of-Cab "CabBox" locker system: Setting this vehicle completely apart from standard over-the-road long-haulers is its high-spec, custom-fabricated rear-cab lockerbox configuration. Built specifically to meet the storage needs of elite operators, this heavy-duty, weather-tight locker system houses auxiliary tools, safety gear, and heavy strapping equipment in a flush-fitting, color-coded structure that perfectly matches the lines of the Highline cab. Premium Kelsa Stainless Lightbar Package: Elevating visibility and show-spec aesthetics to an absolute pinnacle tier, the truck is kitted out with high-quality, British-made Kelsa bars. This includes a sleek roof-mounted HiBar with integrated spot lamps, a low-slung front bumper LoBar, and matching polished SideBars with integrated LED marker lights to illuminate the road ahead. Advanced G33CM Opticruise Gearbox: Power delivery is managed flawlessly by Scania's flagship automated manual transmission. Utilizing an all-aluminum housing that shaves off 60 kg of dead weight, it completely replaces old-school reverse gears with an intelligent planetary reversing mechanism, securing lightning-fast gear changes and highly optimized highway down-speeding curves to preserve fuel percentage. ⭐ Why the Scania 660S V8 Kelsa Custom (2026) Stands Out It hits an absolute pinnacle sweet spot for high-profile fleet operations, successfully combining the massive torque authority and driver retention value of a premium Scania V8 with the ultimate custom workspace efficiency. High-end practical convenience is heavily prioritized, featuring a custom flat-plate aluminum chassis walk-deck, integrated rear-facing LED work lights for safer night-time trailer coupling, and dual high-capacity fuel tanks to maximize long-distance range. Driver comfort is second-to-none, packing a premium air-suspended seat with custom V8 branding, a highly comfortable pocket-sprung bunk, and a car-like steering wheel position to prevent driver fatigue over multi-day journeys. 👉 Subscribe to SCChannel BG for more premium commercial vehicle walkarounds, custom truck deep-dives, and exciting heavy-duty premieres live straight from the Road Transport Expo at Stoneleigh Park! 🔥 Hashtags: #Scania #ScaniaV8 #Scania660S #660SV8 #ScaniaAero #ScaniaSuper #V8Power #SmartDash #Opticruise #MirrorView #RoadTransportExpo #RTX2026 #StoneleighPark #SCChannelBG #TruckWalkaround #CommercialVehicles #HeavyHaulage #SwedishKing #ShowTruck #FlagshipTruck #Kelsa #CabBox #LockerBox #CustomRig
