Walmart has designed a slippery, carbon-trailered big rig
The ubiquitous American supermarket chain operates more than 6,000 trucks, so decided to see what it could do to save a few bucks on diesel. So Walmart has designed this insane, super-efficient lorry in partnership with Peterbilt, Great Dane Trailers, and Capstone Turbine.
The rig features a super-slippery cab that's 20 per cent more aerodynamic than your normal truck, there's a lightweight 53-foot carbon fibre trailer, and it uses a turbine-powered battery-electric hybrid drivetrain. The combustion engine can run on diesel, natural gas and biodiesel, too.
No official economy figures yet, but apparently Walmart is confident its modifications will raise the big rig's mpg from 'infinitesimally low' to 'marginally less infinitesimally low'.
