Get to Market Faster

The Allison Vehicle Environmental Test (VET) Center is an industry-leading facility that allows OEMs, body builders, suppliers and end-users to satisfy their medium- and heavy-duty vehicle testing needs in a single, environment-controlled location year-round.

Customers are now facing increasing system complexity, expanding regulatory requirements and higher demand for ever-faster time-to-market requirements. Allison has you covered. The VET’s one-stop chassis testing can shorten your product development cycles dramatically, facilitating efficiency and ultimately cutting down the costs of bringing your product to market. The VET provides vehicle system development and validation in repeatable, reliable and seasonally independent conditions to get the test results you require.

Results That Matter

The VET’s highly controlled environment enables an enhanced level of virtual product development, driving lower costs. Results from the VET are ideal for developing sophisticated, highly correlated simulations and models so design decisions happen early in the cycle, before prototype hardware investments.

Test Confidently

The VET is operated and managed by Allison Innovative Solutions (AIS), which ensures the facility is secured independently and is dedicated to keeping customer data and property secure and confidential.

Our Export Compliance Program is robust and comprehensive, ensuring that our military customer’s export controlled technology is safeguarded.

How much will the facility be available to the market?

The facility’s use is intended for roughly 50% Allison work and 50% non-Allison work (available to the market).

Can I perform my own testing at your facility?

Allison Innovative Solutions will operate the following services:

  • Test vehicle moving, test preparation, and maintenance
  • Test vehicle driving on/off dyno
  • Engineering support

The customer is allowed to do the following:

  • Test vehicle preparation and maintenance
  • Customers can ride in the vehicle while our techs drive.
  • Engineering support
How do I know my information will not be shared within Allison or other competitors?

Allison Innovative Solutions (AIS) is responsible for the operations of the VET facility. AIS has separately secured data systems, management systems, and sales systems. Allison Transmission is even considered an outside customer to AIS.

Can I send my vehicles to the VET for testing without any of my own support staff?

Allison Innovative Solutions (AIS) is equipped to perform your testing based on test plans and hardware alone. A technical review will be had for each of these milestones:

  • During the quoting process
  • Kick-off meeting after PO awarded and scheduled
  • Test setup confirmation (if needed)
  • Post process data analysis
Am I only able to perform cold starts? How long until the test cell heats up when running?

Not at all. The chamber will maintain ambient temperatures (-50°C < +50°C) continuously as you run your vehicle under heavy loads. This also includes humidity control. The altitude conditions will also be held under heavy power from sea level to 5km of elevation (-40°C < +70°C inlet temperatures).

Can I test hot and cold on the dyne with altitude?
Yes.  The VET’s altitude capability is fully operational across the range of our dyne chamber’s hot environment and cold environment capabilities.
Can I get my test data live, if I send the vehicle for you to perform my testing?
Yes.  While we look forward to collaborating with your teams on-site at the VET,  the VET has live collaboration capabilities that enable our customers to participate in testing from remote locations; saving our customers the cost of entire engineering teams traveling to the test site. 
Can I use your cold and hot testing chambers even if my product is not a vehicle?
Yes.  While the VET was designed to enable vehicle development and testing, our cold environment and hot environment soak chambers can accommodate non-vehicle products.  Please contact us to discuss your unique needs determine how the capabilities of the VET can provide a solution.
