We at HHN Racing e.V. dedicated the year 2021 to revise on our cooling system, steering and wheel hub for one goal: RELIABILITY. Our changes on the car should lead to less technical problems which occourd 2019.We are also proud to say that HNR21's front and rear wing got upgrated and should perform better than ever.

HHN Racing is sending the HNR19 into the race. We did not hesitate to tackle bigger changes to make our 5th car faster than the HNR18. First up is the new suspension system, which strives to improve drivability by reducing steering forces. This year we’re back to spring-dampers and worked hard to get the geometry and setup right. After years of big noses, we’re proud to say that the HNR19 comes with a fresh look and improved aerodynamics. Just one hour apart, FSG is a home match for us!

The wings are back! The HNR18, the fourth car by HHN Racing, features a new aero package for increased downforce. This and a reworked suspension system allows us to master curves at higher speed. Further development of the engine leads to a power and torque gain of 15% compared to the HNR17. A novelty is the usage of custom ECU functions for the single-cylinder engine. For improved ergonomics, we use an e-paper display, new seat and shift paddles amongst other things.

In 2007 two students had the idea to found a Formula Student team representing the University of Applied Science Heilbronn. During the following years they achieved to build a team which has about 15 team members today. The most important improvement of the Raptor 2013 is the frame which is designed according to the Alternative Frame Rules to decrease weight without losing stiffness. Furthermore, we designed new uprights with center-lock wheel hubs, optimized wiring harness, steering wheel with integrated multifunctional display, optimized suspension mounting and the bodywork made of carbon. The one cylinder engine from Husqvarna is modified with two injection valves, a 6-liter airbox and a 4-gear-transmission based on the original gearbox to improve the performance in the dynamic events. In addition to that an automatic clutch system will help the driver to focus on the track. We are also well-prepared for the static events with a detailed Cost Report and an elaborate Business Plan.
