Longhorn Racing

Thank you so much for all of your support! A huge thanks to Justin Acosta for helping us this whole time. We truly appreciate everything you have done for Longhorn Racing. We are excited to see how this partnership may grow with time!

Lattice is proud to support The University of Texas at Austin's automotive engineering team, Longhorn Racing. It was great to attend their unveiling event and see the team's latest vehicles ahead of this summer's design competitions. Congrats & Hook’em! 🤘

Had a great time supporting the UT Longhorn Racing Unveiling event! It's always inspiring to see the hard work, innovation, and passion these students bring to life through engineering and teamwork.

Recently, our Solar team had the incredible opportunity to participate in a roundtable discussion with our new partner, Austin Energy! We explored the future of electrification in Austin, how power grids would change with an increasing amount of electric vehicles, and how Austin Energy is working to support a citywide transition to solar power in the near future.  During the session, we learned about impactful programs and initiatives that have the potential to benefit large portions of the community. Our team had insightful conversations with Austin Energy representatives about The Ivory, a new sustainable community being developed in East Austin. We discussed how electric-powered public transportation is being integrated into the design to encourage car-free living. We also covered the six types of energy procurement used by the City of Austin and why there’s growing optimism around solar and nuclear energy. It was exciting to hear about the initiative to move away from biomass and fossil fuels. Overall, the experience was both inspiring and educational. As we continue to develop our solar project, it was motivating to hear directly from professionals who are leading the charge in renewable energy. A huge thank you to Amy Atchley, Bobby Godsey, Cameron Freberg, and Zachary Ionadi for hosting us! And shoutout to our amazing team members, Erika Feller, Niloo Adib, Pratyush Patra, Frank Li, Aneri Patel, Annie Wang, Gerard Cardenas, Arav Chheda, Kadhir Vivekanandan, Hardhik Sripuram, and Annika Moon for making this event such a success!

As we approach our 2025 Unveiling event on April 19th and FSAE EV comp in June, the past few months have been a whirlwind of progress. Every team member has been working hard to bring our 2025 electric vehicle to life! Here's a glimpse into what Longhorn Racing Electric has been up to during the first quarter of 2025: Aerodynamics: Our aero team has made tremendous strides, recently receiving the nose cone and side panel molds that were delivered to our partner Peterbilt for CNC machining in February. Manufacturing has begun for these critical components, with carbon fiber layups in progress! Meanwhile, the team is putting finishing touches on a wooden front wing mold, with undertray and sidepod molds underway. The livery is nearing completion and we'll be wrapping our bodywork soon! Body: The frame of our 2025 vehicle has reached a major milestone with full frame welding completed! Our body team put in countless hours and overcame numerous challenges to reach this critical stage. Now they are powering through system tabs to finish up the frame! Dynamics: Our dynamics team has completed critical manufacturing of our un-sprung assemblies and test assemblies have begun! Additionally, we have created comprehensive test plans based on ISO standards to extract stability and response parameters for suspension tuning. These tests will include skid-pad style evaluations and various movements designed to map driver inputs to vehicle response. The team is also producing machined parts including control arm apexes, anti-roll bar components, and the steering gearbox housing! Electronics: Our final revisions of printed circuit boards arrived and the electronics team is completing functional and reliability testing before they go on the car! The boards this year support power and code updates over USB-C—no programming cards required. Our web server is up and running to display real-time vehicle telemetry as well as program the car via a 5G cellular connection. This will be our most advanced sensor suite yet. Examples include measuring suspension loads with strain gauges and ride height with lasers. Powertrain: Drivetrain mounts for both motor and differential have been finalized, and manufacturing has begun! Soon the team will conduct testing with our 2024 EV to determine the viability of our full carbon fiber half-shafts. Battery manufacturing is making major headway, and machining of the sprocket will commence soon! We're working hard towards our next major milestones: wheels down and powered run. Wheels down will mark the completion of frame, dynamics, and drivetrain systems, allowing our car to physically rest on its own weight. Powered run will follow shortly after, when battery and electronics integration enable the car to move under its own power. It’s all-hands-on-deck across every system; the dedication and ingenuity of our team continues to amaze us every day!

Last month, our Officer Board and several Longhorn Racing (LHR) members traveled to Dallas to host an outreach event with Santander Consumer USA and Dallas Independent School District (ISD). At the event, we taught Dallas ISD middle schoolers about aerodynamics with a focus on Formula 1 cars. Each LHR member worked with a team of students and collaboratively built aerodynamic parts to make a LEGO race car. The race cars were even tested in wind tunnels! A total of 12 teams each raced against each other, with the winner from three rounds progressing to the final round, where a 1st, 2nd, and 3rd prize was awarded. The event was a HUGE success, with engagement from both LHR members and Santander executives. We greatly appreciate Santander’s continued support and contributions that aid our engineering, manufacturing, and validation processes. Here is video of the wind tunnel (we made)! Thank you to everyone who helped build the wind tunnel!

Ride onboard with our driver Andrew Cloran at the 2024 Texas Autocross Competition hosted by UTA Racing! He was piloting Angelique, our 2024 Formula SAE EV car. Angelique is powered by an air cooled 600 Volt battery with an Emrax 228 Axial Flux Permanent Magnet motor that makes 107 hp and 516 ft-lbs of torque at a curb weight of just 372 lbs. On his third lap of the day Andrew set Longhorn Racing Electric's fastest time, a 57.365!

Our 2024 FSAE EV, Angelique, hit the track recently with a Longhorn Racing Electric alumni behind the wheel!

We're proud to sponsor the next generation of innovators! 🙌 TDK-Lambda is excited to sponsor the Longhorn Racing Team from the University of Texas as they bring their cutting-edge design to life. https://ow.ly/sn7O50UNOi9 This year we donated our Z-650-1.25-U power supply to aid in their manufacturing and test process. As the team embarks on their manufacturing season after completing the design of this year's car, they shared: "High voltage electronics is difficult. Thankfully, TDK-Lambda's unit allowed us to test our electronics at 600 volts" We're thrilled to see our technology helping these talented students achieve their goals and push the boundaries of engineering. Best of luck to the University of Texas Solar Vehicles Team. https://ow.ly/45tO50UNOi8 We can't wait to see the finished car on the track! 🏎️ ✨Learn more about our University Sponsorship Program here: https://ow.ly/Ycqx50UNOia 💫#TDKLambda💫#powersolutions💫#LonghornRacing 💫#EngineeringExcellence 💫#StudentInnovation
