New 4×4 dyno for Jeeps

by David Zatz on

The Chrysler Technical Center (CTC), possibly the most advanced automotive engineering facility in the world, has added a high-capacity snow-wind-and-heat dynamometer for all-wheel-drive vehicles.

Since the 1990s, CTC had special dynos which threw snow at cars at high wind speeds to make sure the wipers and air openings didn’t fail during blizzards. Now, a test cell has been adapted to high-powered AWD vehicles, slamming snow against them at -40° in 100 mph winds, or baking them at 130°F.

The wind and temperature capabilities are unchanged; what’s new is a $2.5 million investment to handle up to 350 hp up front and up to 650 hp in back, partly for Jeeps, and partly for the Cummins 4×4 pickups (currently these top the segment with 900 pound-feet of torque).

FCA wrote that the CTC continues to be the only headquarters in the world where a design can go from sketch to prototype. It is the second largest building in America, after the Pentagon, with 5.4 million square feet of space, and insiders told Allpar that it’s once again full (when it was first built, Chrysler also had the Jeep-Truck Engineering Center on Plymouth Road).

The CTC boasts the highest wind speeds (160+ mph) of any domestic OEM’s wind tunnel, and 129 dyno cells running seven days a week, 24 hours per day. The 14,000 people in the building are a historic peak.
