The Walmart Advanced Vehicle Experience, or WAVE, concept truck is the retailer’s answer to increasing efficiency on the road. Walmart is the first to create an all carbon fiber trailer made of 53 foot panels. The trailer is made almost exclusively with carbon fiber, saving around 4,000 pounds which can then be used to carry more freight.

In 2005, Wal-Mart set a goal of doubling the efficiency of its truck fleet by 2015. Chris Sultemeier, senior vice president and head of corporate transportation services for Wal-Mart said the company reached 80% of its goal by purchasing more fuel-efficient trucks and finding ways to ship more goods in less space and using fewer trucks. Walmart Corporate announced the project Feb. 17 during a meeting to report on progress with reaching the company’s sustainability goals.
