After completing the ornithopter, the team moved onto their next project, breaking the world speed record for land single-rider cycling. During the first year, no vehicle was successfully built, except for a carbon fibre frame which went on to become a training vehicle.

Taking what they learned in previous years, Vortex was built. Vortex was superior to ACE in many ways: it boasted superior aerodynamics, simpler front wheel fairing, a removable drive-train mechanism and used a door rather than a split dividing the top from the bottom. It was also much smaller with a length of approximately 7 ft.The team took Vortex to compete in the ASME HPVC, this year on the Indianapolis speedway. The team placed 1st in women's sprint, 2nd in men's sprint, 1st in endurance, 6th in utility and 3rd in design. The team was awarded 1st overall in the competition.

In September of 2011 the team competed in the Battle Mountain WHPSC again, this time in hopes of setting a world speed record. After a week of racing the team marked a top speed of 116.9 km/h by Todd Reichert, still well short of the world record.

WHPSC 2012 was disappointing. A variety of handling and visibility problems prevented Bluenose from reaching its potential, and the team failed to improve upon Vortex's top speed.

During the summer of 2014, members of HPVDT collaborated with AeroVelo Inc. to design and build the Eta speedbike. With a myriad of new design features and unparalleled aerodynamic quality, Eta was a favorite among the HPV community to set a new speed record. In order to better support the Eta project, HPVDT did not field any of its own vehicles at WHPSC 2014. Along with AeroVelo's top athlete Todd Reichert, HPVDT/AeroVelo riders Trefor Evans and Calvin Moes competed in the week of racing. Todd managed to set a personal best speed, but did not achieve the goal of a new world speed record. Following the competition, strategic differences between AeroVelo and HPVDT resulted in the two organizations ceasing large-scale collaboration. As part of this agreement, HPVDT retained the right to build a "clone" of the Eta speedbike.

==Viteza (2014 - 2015)==
Again working towards a more practical vehicle design, the team came up with a partially-faired lowracer - a recumbent bike with very little frontal area. The design included several novel features, including an ill-fated carbon leaf spring suspension system. The 2015 ASME competition was a mixed experience. The new Viteza design proved less versatile than expected, and the suspension system introduced unanticipated instabilities. Regardless, the team scored well in Innovation and won 1st place in the Design event.

Through the summer, work on Eta prime was completed and the team raced it for the first time at WHPSC 2016. At the same event, former team founder Todd Reichert set a new absolute world record of 144.17 km/h (89.59 mi/h) in Eta.

==Cyclone (2015-2016)==
==Cyclone (2015-2016)==
While continuing work on Axios and Eta Prime, HPVDT designed an improved version of Vortex called Cyclone. Cyclone features a more sophisticated drivetrain structure, retractable landing gear for low speed stability, and improved composites techniques, resulting in a lighter vehicle. The vehicle was not completed in time for ASME 2016, but was completed and raced at the Northbrook Velodrome in July of that year. The vehicle suffered from poor drivetrain reliability and insufficiently stiff landing legs.

Evan Bennewies and Alan Pettit led the ASME project to build another iteration of Vortex called Tempest. It refines the concept of Cyclone explored the previous year, featuring reinforced landing legs, a quick release drivetrain assembly, and compatibility with the very fast Michelin blue eco-marathon tires. The vehicle competed at ASME HPVC 2016, and was thereafter used at HPRA races and for training new riders. Though the vehicle improved upon the reliability of Cyclone, it never reached the same consistency as Vortex.

The team refines Eta prime over the summer and gets it in good working order while Calvin familiarizes himself with its handling. The team also restores Bluenose and sends both vehicles to Battle Moutain. At WHPSC 2017, Calvin reaches a maximum speed of 127.62 km/h (79.30 mi/h), the highest speed of that year's competition. Most of the other team members in attendance also each attain personal bests.

==Arbiter (2017 - 2018)==
==Arbiter (2017 - 2018)==
The team pursues a fully faired recumbent tricycle with external wheel pods called Arbiter for ASME under project director Bruce Hu. The design features a tadpole configuration and two external front wheels with co-moving wheel fairings, steered by a four bar linkage.  For the first time in team history, the vehicle is test ridden before the competition. The vehicle suffered a mechanical malfunction in the right steering rod during the first heat of the Women's drag event and the damage prevents the team from competing in either drag event. However the team works through the night and the vehicle is once again functional the next morning and finishes the endurance event in 4th place. In May, Bill Kong succeeds Calvin Moes as captain. For World Speed Challenge, the team sends Eta Prime and Bluenose again where Calvin finally earns his long awaited 80 mph hat and finishes the competition in second place overall.

==Zephyr (2018 - 2019)==
==Zephyr (2018 - 2019)==
For ASME, the team builds the partially faired upright bike Zephyr. The design features front and rear fairings inline with the rider's torso, significant use of prepreg carbon, streamlined frame, and wheel sections, and a wide range of positional adjustment. The vehicle was again tested and ride-logged before the competition and performed smoothly throughout the event. Zephyr took first place in both Men's and Women's drag events and dominated the Endurance event, lapping the second-place vehicle seven times.

Calvin starts a new project for a two-seater speedbike, Titan. The design is similar in many ways to a scaled-up Eta prime. The vehicle is taken to Battle Mountain for WHPSC 2019. On Friday night, September 13th, 2019, Calvin and Evan push Titan to 120.27 km/h (74.73 mi/h) and set a new world tandem record.
