So after the not so secret build up and a few leaks online yeterday, HPI have finally lifted the ol Cuban missile Crisis embargo on their 4WD World Championship challenger, the D413 – Ty Tessmann’s weapon of choice.
Thanks to some stellar co-operation with HPI, NeoBuggy was granted exclusive access to Tessmann’s buggy, the standard car photos are available here. We caught up with HB designer Torrance Deguzman who explained some of the interesting features of the new 4WD 1/10th buggy.

Starting from the outside one of the main features that sets it apart from the competition is the three-piece undercut body – three piece for that reason; you can’t get an undercut body out of the mould, so three pieces is the solution. Next up the chassis layout which can accommodate both sadle and shorty packs with all required parts to fit them both included in the kit, a simple turning of the centre bulkhead is all that’s required to alternate from saddling up or shortying.
The key ethos during the design of the car has been strength and durability, its clear from the outside that the D413 is a beefy looking buggy – resembling an 1/8th scale that’s been shrunk in the wash.
Deguzman went onto say that the current crop of 4WD are quite fragile, so an effort to get around this, the shock tower design is triangulated, lower arm mounts are inspired by touring car – inserts holding hingepins, adjustable and threading into alu inserts in the gear case.
One of the most identifiable features is the signature monocoque lower suspension arms, which use a lower shell and cover, this has allowed the team to use tougher material in the arms and less glass inside, giving it more impact strength and rigidity, whilst using different carbon insert pates you can adjust the stiffness of the arms.
The car uses three gear diffs, machined steel ring gears and an one piece machined steel input gear where the dogbone simply slides in. Other features include vertical ball studs on the suspension, adjustable Ackermann, roll center, extra long shocks for maximum up and down travel, sway bars, three available also included. Expect the car sometime later this year or early 2014 we hear.
