Ontario Tech acknowledges the lands and people of the Mississaugas of Scugog Island First Nation.

We are thankful to be welcome on these lands in friendship. The lands we are situated on are covered by the Williams Treaties and are the traditional territory of the Mississaugas, a branch of the greater Anishinaabeg Nation, including Algonquin, Ojibway, Odawa and Pottawatomi. These lands remain home to many Indigenous nations and peoples.

We acknowledge this land out of respect for the Indigenous nations who have cared for Turtle Island, also called North America, from before the arrival of settler peoples until this day. Most importantly, we acknowledge that the history of these lands has been tainted by poor treatment and a lack of friendship with the First Nations who call them home.

This history is something we are all affected by because we are all treaty people in Canada. We all have a shared history to reflect on, and each of us is affected by this history in different ways. Our past defines our present, but if we move forward as friends and allies, then it does not have to define our future.

What’s cooler than cool? Ice cold -40C conditions for new vehicle testing inside ACE at Ontario Tech

ACE Climatic Wind Tunnel helping GM Canada test new electric Hummer for weather durability

Extreme-cold weather testing of future GMC HUMMER EV (electric vehicle) inside the ACE Climatic Wind Tunnel at Ontario Tech University (wind tunnel temperature approaching -40 degrees Celsius).

Baby it’s cold inside. Really cold.

When GM North America tests new vehicles for cold weather durability, much of the development work takes place outdoors during the winter in Northern Ontario at GM’s Kapuskasing Proving Ground.

But when winter ultimately retreats, the automaker can still conduct the same frigid tests, some 800 kilometres to the south, by going indoors at the massive Automotive Centre of Excellence (ACE) Climatic Wind Tunnel at Ontario Tech University in Oshawa.

This spring, GM’s Canadian Technical Centre engineers have become the first to evaluate the GMC HUMMER EV (electric vehicle) pickup in the extreme cold at ACE. The vehicle is expected to be ready for the market in Fall 2022.

While at ACE, the HUMMER EV pickup is subjected to consistent minus-40 Celsius temperatures. ACE engineers tether the vehicle on a dynamometer that allows the HUMMER EV to operate at typical highway speed while also being buffeted by typical highway headwind speeds in the wind tunnel.

GM’s electric vehicles undergo the same rigorous durability testing that internal combustion engine vehicles experience. Engineers rely on ACE’s capabilities to help them identify vehicle performance issues to prevent them from ever reaching customers. From the propulsion system to power seats and tailgates, wind whistles, rattles, squeaks, and cabin comfort – Canadian engineers work hard to ensure each GM vehicle’s software and hardware features will perform in extremely cold temperatures.

ACE’s world-class research and development facility also features thermal chambers adjacent to the Climatic Wind Tunnel that allow engineers to test and study GM vehicles and systems in a steady, repeatable environment. In fact, about five per cent of GM North American vehicles visit the ACE Wind Tunnel for cold weather durability testing when development timing falls outside of GM’s winter season.
