NEW AND IMPROVED ‘ASTRO BODY’ RETURNS TO GM FCO LINEUP

For commercial customers who loved the Chevrolet Astro and GMC Safari for their versatility and capability, GM has great news: the all-new Astro Body package on 2007 Chevrolet Colorado and GMC Canyon pickup trucks improves on the original.

“Shortly after we discontinued Astro and Safari, a number of our commercial customers told us that the midsize vans filled a number of important needs. Many of these customers, for example, used Astro and Safari for trade applications, such as plumbing and HVAC. For these customers, Astro and Safari were the lifeblood of their business. With the Colorado and Canyon Astro Body, we took the best of Astro and Safari and made them even better,” said Tim Cavanaugh, marketing product manager for General Motors midsize trucks.

More cargo-carrying capability

Of primary importance to trade customers is cargo-carrying capability. Many of these customers equipped Astro and Safari with storage bins and partitions, turning these vehicles into rolling repair centers. The 2007 Astro package delivers more capacity than did the original midsize vans. Compared to the 2005 Astro and Safari Vans, the Astro Body is taller (78 inches vs. 75 inches), longer (82 inches vs. 80 inches) and can carry wider items (43.1 inches above the wheelhousings) safely and securely inside the vehicle. Colorado and Canyon Astro Body customers can also carry more cargo than they could in Astro and Safari vans (173.7 cubic feet vs. 170.4 cubic feet). Total payload capacity for Colorado and Canyon Astro Body is nearly that of the midsize vans (1,515 pounds vs. 1,647 pounds) once one considers that the midsize vans required a driver partition that weighed approximately 100 pounds.

Cargo loading and unloading is easily accomplished via either the 30-inch side door opening or the 48.45-inch double rear doors that swing out 180 degrees for greater efficiency. The side and rear doors are keyed the same as the vehicle cab for greater convenience.

Enhanced visibility

The Colorado and Canyon Astro package delivers enhanced safety and security by improving the driver’s field of vision alongside and behind the vehicle. Side-view visibility is enhanced by the new Velvac mirror. It uses a built-in convex mirror, extending visibility along the side of the vehicle significantly vs. the Astro Van. A camera that is mounted just below the Center High Mounted Stop Light (CHMSL) provides rearward visibility. With it, drivers can clearly see if an item as small as a wrench has been left on the rear bumper.

Integrated styling

“It was critical to us that the styling for the Astro Body mesh seamlessly with the Colorado and Canyon styling. We’ve incorporated a number of subtle styling enhancements to achieve this objective,” Cavanaugh explained.

The box portion of the Astro package features the same door handles, taillights and CHMSL as those on Colorado and Canyon models. The box is made of commercial-grade fiberglass for enhanced durability, and the interior features a durable floor and a 12-volt dome light. For warmer climates, vents are available.

A host of bin packages and ladder racks are available from longtime GM suppliers Adrian and Crown.

More powerful, more efficient engines

The standard engine on Colorado and Canyon Astro is the new 3.7L I-5, which delivers 242 horsepower and 242 lbs.-ft. of torque. It features variable valve technology (VVT), electronic throttle control and other features that contribute to high levels of operating efficiency and fuel economy. Balance shafts help ensure smooth operation of the engines, providing a higher level of refinement. The 3.7L is coupled with the Hydra-Matic 4L60 electronically controlled four-speed automatic. The Astro package is available on Colorado and Canyon Chassis Cab models and in 2WD and 4WD configurations.

The 2007 Colorado and Canyon Astro package joins the Colorado and Canyon Mid Box and Topper packages, as well as the Chevrolet Uplander Cargo Van. These vehicles were specifically designed based on customer input and are engineered to offer GM Fleet and Commercial customers unique models designed for their unique uses, ordered right from the factory and backed by GM warranties and service.

*Horsepower and Torque Certified. A new voluntary power and torque certification procedure developed by the SAE Engine Test Code committee was approved March 31, 2005 . This procedure (J2723) ensures fair, accurate ratings for horsepower and torque by allowing manufacturers to certify their engines through third-party witness testing. GM was the first auto manufacturer to begin using the procedure and expects to use it for all newly rated engines in the future.
