Why VTX
First to Introduce Protoless Design
VTX introduced the PROTOLESS design scheme — CAE-based vehicle development that delivers higher performance at lower cost, because validation happens before hardware exists.
No Prototype Fleet
Most of the design is fixed at concept stage. Fewer CAD releases, fewer analysis loops, no prototype build phase.
30 Years, 20 Full Vehicles
More than 30 years of vehicle development experience — 20 full vehicles, 6 new engines, 9 EV programs — backed by an in-house benchmarking database covering passenger cars, MPVs, SUVs, EVs, HEVs, buses, trucks, and UTVs.
Two ways to work with VTX.
We run vehicle programs, and we license the software we run them with.
We run the development for you.
Full vehicle and battery system design, validated through simulation. From concept through CAD release.
Or run it yourself, with our tools.
The same software VTX uses on every project — design automation, analysis automation, and a benchmarking database. Licensed for in-house engineering teams.
Four steps, no prototype in between.
Database
Start from a validated reference model instead of a blank CAD file.
Mapping
Morph the reference into the new vehicle's geometry in minutes, not weeks.
Automated Analysis
Run the full validation set — structure, NVH, crash, dynamics, CFD — without manual setup.
Optimization
Converge on the lightest structure that meets every target, then release CAD once.
Supporting Physics
Every discipline runs against a single integrated model — the one used for design, not a rebuild.
