Rapid Transit Protocol
The Rapid Transit Protocol reimagines the 2010 Kia Soul as a high-speed Wangan time attack machine, flawlessly balancing aggressive aerodynamic innovation with the Soul’s distinctive boxy silhouette. Extensive widebody modifications extend the fenders by up to 180mm, sculpting complex convex and concave profiles that channel airflow to reduce drag and generate ground-effect downforce. Carbon fiber aero components—including a bulged hood with staggered NACA ducts, a deep front splitter with dive planes, and a multi-strake rear diffuser—work in harmony to maintain stability during sustained runs above 250 km/h on Japan’s expressways. Beneath the skin, a turbocharged 2.0L inline-4 is paired with a rally-inspired sequential paddle-shift gearbox, torque vectoring, and enhanced cooling systems optimized by active aero ducts. Wheel and tire setups are meticulously chosen for maximum grip and thermal endurance, with widened tracks supporting ultra-low profile semi-slicks on forged alloys. This build transforms an everyday hatchback into a precise, street-legal weapon engineered for the unique demands of Japan’s high-speed time attack culture.

Track
Designed specifically for Japan’s high-speed expressways, this build excels in sustained velocity and aerodynamic stability above 250 km/h. The widened tracks, aggressive aero balance, and calibrated suspension setup provide precise handling and grip for time attack conditions, delivering confidence in high-speed lane changes and extended cornering at elevated speeds.
Body Modifications
Front fenders extended 140mm with convex-to-concave arch profiles and integrated brake cooling ducts
Rear quarter panels flared 180mm featuring layered box flare and aerodynamic shelves
Carbon fiber reinforced widebody arches for structural rigidity
Lowered door sills with integrated aerodynamic sidepods housing cooling ducts
Aero Components
Full-width composite front bumper with 165mm deep trapezoidal splitter and dual dive planes
Carbon fiber hood bulge with dual staggered NACA ducts and rear extraction channel
Seven-strake full-width rear diffuser extending 260mm behind rear axle
Dual-element 1660mm wide GT wing mounted on carbon fiber swan neck pylons
Aero
Aerodynamic modifications include a composite front splitter with upward angled dive planes generating front axle downforce, paired with brake cooling ducts integrated into wide fenders. The carbon fiber hood features dual NACA ducts and a rear extraction channel to manage under-hood airflow. At the rear, a seven-strake diffuser and a dual-element GT wing mounted on swan neck pylons deliver balanced downforce and airflow acceleration, ensuring stability during high-speed expressway runs.
Wheel and Tire Setup
Front: 19x10 Work Emotion XD9 forged alloys wrapped in 295/30-19 Bridgestone Potenza RE-71R semi-slicks
Rear: 19x11 wheels with 315/30-19 high-stability semi-slick tires
Front and rear tracks widened by 300mm and 360mm respectively
Ultra-low profile tires optimized for expressway grip and thermal endurance
Wheels
The front wheels are robust 19x10 forged Work Emotion XD9 alloys shod with 295/30-19 Bridgestone Potenza RE-71R semi-slick tires, chosen for their grip and heat resistance. The rear setup expands to 19x11 wheels with 315/30-19 tires, emphasizing stability and traction during long high-speed sections. This staggered, wide track configuration complements the aerodynamic enhancements for maximum performance.
Stance
The stance features a widened track—300mm front and 360mm rear—to optimize lateral grip and aerodynamic efficiency. Ride height is set at a conservative 65mm static clearance with a 35mm aerodynamic rake rearward, balancing downforce distribution for sharp turn-in and high-speed stability. Adjustable coilovers with hydraulic bump stops refine suspension response for precise control.
Powertrain Concept
Upgraded turbocharged 2.0L inline-4 with direct injection and enhanced cooling
Sequential paddle-shift gearbox adapted from rally development for rapid ratio changes
Front-wheel-drive layout with advanced torque vectoring
Brake-by-wire system integrated for precise modulation during high-speed runs
Engine
The build utilizes a turbocharged 2.0L inline-4 engine equipped with direct injection, enhanced intercooling, and an upgraded cooling system fed by active hood and front bumper ducts. This powerplant delivers responsive mid-range torque and refined power delivery, optimized for sustained high-speed runs and time attack demands.
Drivetrain
Maintaining the front-engine, front-wheel-drive architecture, the drivetrain integrates a sequential paddle-shift gearbox sourced from rally applications for lightning-fast gear changes. Torque vectoring and a brake-by-wire system improve traction and cornering precision, enabling confident, agile performance during rapid lane changes and expressway sprints.
