In contrast to multipart plastic tub chassis prone to flex, the RS4 Sport 3's one-piece moulded chassis delivers exceptional rigidity and torsional stability. This translates to enhanced handling precision and responsiveness, giving you a competitive edge on the track.

The HPI Racing RS4 Sport 3 is incredibly easy to drive and control. Simply plug in the battery, switch on the radio and car, and you're ready to go! The included steering wheel controller provides a natural and intuitive driving experience, just like a real car. Steer with the wheel, and use the trigger for forward, brake, and reverse. You'll be mastering the track in no time!

An adjustable cam-style servo saver protects the steering servo from crash damage. This spring-loaded servo saver absorbs impact forces, preventing damage to the servo gears during collisions. Drive with confidence knowing your steering system is protected, even during aggressive driving.

This durable bumper provides protection for the suspension, chassis, and body during impacts, ensuring your car can withstand the rigours of on-road and off-road driving.

The drivetrain is sealed for optimal performance and durability. The motor is mounted longitudinally alongside a central driveshaft that runs the length of the car. This entire drivetrain, including the driveshaft and gear differentials, is fully sealed to protect it from dirt, rocks, and debris. Ball bearings throughout the drivetrain maximise efficiency and ensure smooth operation.

The HPI Racing RS4 features easy-access differentials for quick and convenient maintenance. Simply remove 4 screws to access the differentials, allowing you to change the grease, inspect the gears, or perform general service with ease.

The RS4 Sport 3 boasts adjustable-height body mounts, allowing you to install any 1/10th scale touring car body from HPI Racing onto the chassis. Simply adjust the front and rear mounts to ensure proper clearance for the wheels and chassis components beneath the body. Body pins secure the mounts in place, while multiple mounting hole positions provide fine-tuned body fitment for a personalised look.

The rear hub features a vertical ball stud adjustment, enabling effortless rear roll centre customisation.  Adjusting the ball stud height with optional spacers directly influences rear-end traction as the car navigates corners. Additionally, the suspension arm offers three distinct shock mounting holes for convenient shock angle fine-tuning.

HPI achieved exceptional handling in the RS4 Sport 3 by strategically positioning components as low as possible in the chassis. This design results in an ultra-low centre of gravity, significantly enhancing cornering performance.
