FlexFuel Chevrolet Avalanche

This extreme expedition vehicle ran 50,000 miles without any petroleum fuel.  It  helped  EcoTrek evolve our understanding of cellulosic  ethanol made from non-food organic materials like corn husks, waste paper and dead trees.

Algae-Powered Ford F350

Powered by cutting edge Algae-Based Biodiesel, this vehicles has a range of 1,500 miles and is equipped with a full kitchen and four beds.  Plus, most aftermarket accessories are made from recycled and/or recyclable materials.  

Biodiesel Hummer H2

GM said putting a diesel engine in a H2 Hummer was impossible.  We proved them wrong, tripled its fuel efficiency to 24 mpgs, and ran it on biodiesel made by American farmers. 

Award-Winning GM Heavy-Duty Truck

EcoTrek was given 3-weeks to customize this truck for the world-famous SEMA Show.  Not only did we finish, we won "Best Accessorized Vehicle" by GM at that event.  By the way, every part we used was made of recycled and recyclable materials, as we drove this truck to SEMA using 100% biodiesel.  

EcoTrek's Hybrid Silverado

One of the first hybrid pickup trucks on the road, EcoTrek helped GM usher in this technology in high-mpg trucks. Current versions of such vehicles are helping fleet operators get closer to zero-net-emission goals. 

CNG-Powered Kia by EcoTrek

Kia didn't bring many of these full-sized SUVs into America.  EcoTrek received one and converted it to run on either gasoline of CNG at the flip of a switch.  

Aerodynamic Biodiesel Mercedes-Benz

Adding a low-profile body kit, low-rolling resistance tires and lightweight wheels to our Mercedes-Benz, and then running it on biodiesel, we increased its full-efficiency by 18%+.  With careful driving techniques, we averaged over 48mpg during 30,000 miles of driving.  

EcoTrek Saturn Sky

In our early days, GM asked us to do "eco-upgrades" to their Saturn Sky. We increased its output to 300hp, while running it on ethanol.  In later years, EcoTrek used only cellulosic ethanol made from non-food products.  

Lightweight Kia Optima Hybrid

With the use of lightweight materials in the hood, wheels and tires of this Kia Optima Hybrid, we were able to decrease the vehicle"s weight and increase its fuel efficiency to over 50mpg.
