[Quick Summary] BYD’s personalized premium sub-brand, Formula Leopard, has expanded its official showcase for the upcoming “Fangcheng S” personalized vehicle line, locking the spotlight onto its elite flagship sedan—the Formula Leopard SL. Riding on a cutting-edge pure electric platform, the premium long-wheelbase sedan introduces BYD’s highly anticipated 2nd-generation Blade Battery, extreme flash-charging technology, and a driving range exceeding 1,000 kilometers (621 miles). Officially scheduled for a market launch in Q3 2026, the Formula Leopard SL elevates the sports-executive segment by pairing commanding wide-body proportions with an active electric deploying rear wing.
Editor’s Note regarding the S-Series Lineup: The “S” series introduces an innovative “one car, multiple forms” product strategy designed to simultaneously capture premium younger buyers and premium executive fleets. While the series includes the standard S and the SGT shooting brake, the Formula Leopard SL stands as the larger, long-wheelbase flagship three-box sedan, slated to hit global-ready production tracks later this third quarter.
1. Design & Stance: The Grand Wide-Body “Suit & Tie” Performer
The Formula Leopard SL marks a major departure from sterile sedan designs, merging sleek aerodynamics with aggressive, luxury details:
- Flagship Footprint: The SL boasts imposing executive proportions, measuring exactly 5 meters (196.8 inches) in length, 2 meters (78.7 inches) in width, and anchored by a massive 3-meter (118.1 inches) wheelbase to maximize cabin stretch-out comfort.
- Bespoke Aerodynamic Suite: To optimize high-speed airflow, the vehicle features premium integrated body kits, including a “Wind-Riding” front splitter , aggressive wide-shoulder wheel arches, and a deep performance rear diffuser.
- The SL Active Wing: Setting it apart from its stablemates, the Formula Leopard SL comes exclusively equipped with an advanced deployable electric rear spoiler , which automatically raises at highway speeds to increase rear downforce and stability.
- Clean Profiles: The side profile maintains an ultra-clean, low-drag aesthetic utilizing semi-hidden door handles and a smooth, sweeping fastback roofline that resolves into a sporty rear ducktail accent.
2. Pinnacle Mechanicals: 2nd-Gen Blade Battery & Smart Chassis Control
Under the hood, BYD has deployed its most advanced energy storage and vehicle dynamics platforms into the Formula Leopard SL:
- The 1,000km Range Milestone: The SL will run natively on BYD’s breakthrough 2nd-Generation Blade Battery paired with high-voltage flash-charging technology. Capable of single-charge ranges exceeding 1,000 kilometers (CLTC), the powertrain represents the pinnacle of long-distance grand touring efficiency.
- BYD DiSus Chassis Architecture: The sedan comes equipped with BYD’s world-renowned DiSus intelligent hydraulic/air body control system. By continuously adapting damping characteristics in real-time, it keeps the massive 5-meter chassis perfectly flat and composed through sharp maneuvers.
- Active Rear-Wheel Steering: Despite its long 3-meter wheelbase, the Formula Leopard SL maneuvers with compact-car agility thanks to standard active rear-wheel steering, significantly shrinking its turning radius for effortless urban parking.
3. High-Silicon Intelligence: DiPilot 5.0 & Generative AI Cabin
The intelligent infrastructure of the Formula Leopard SL matches its mechanical prowess, offering a true hardware-rich ecosystem:
- DiPilot 5.0 “Eye of God” Autopilot: The vehicle carries a sleek, roof-mounted watchtower LiDAR sensor. Operating on the DiPilot 5.0 platform, the SL delivers full-scenario automated driving capabilities, enabling effortless, mapless Highway NOA and complex Urban NOA out of the box.
- Generative AI Smart Cockpit: Confirmed by Formula Leopard’s General Manager, Mr. Xiong, the premium cabin centers around the advanced DiLink intelligent ecosystem. The tech stack features an oversized central floating touchscreen display, a high-fidelity holographic Head-Up Display (HUD), and a proprietary localized voice Large Language Model (LLM) to facilitate ultra-smooth, contextual multi-turn natural conversations.
