The 2013 gmc sierra 1500 hybrid is the only hybrid in the full-size truck segment. Compared with comparable non-hybrid models, it delivers 33% greater city fuel economy and a 23.5% improvement in overall fuel economy. It still delivers a 6,100 1b. towing capacity. 2WD and 4WD models are available. 53-55 green choice The smartloop internal hot water recirculation system can save up to 40% in energy and water consumption. Ideal for commercial projects such as hot water supply lines in hotels, hospitals or multi-story office buildings, it uses a supply riser to insulate the in-liner tubing. (There is no need for a separate return pipe.) Water stays hotter longer and remains in constant motion, reducing the risk of le-gionella and other water-bourne pathogens. Because the system uses fewer fittings, supports, penetrations and core drilling, it reduces labor and materials costs. The system makes use of the company's ProPress fitting technology, meaning there is no sweating, brazing or grooving, and no need for a fire watch. The system is lead-free and complies with the most stringent zero-lead legislation.
