It was designed to pass military -
grade durability tests and features a reinforced rubber bumper protecting the chassis, a spill - proof keyboard, as well as metal hinges treated with zinc alloy.
* Horsepower and torque expected to top previous model (
testing is ongoing — check media.gm.com for updates) * NOx emissions reduced at least 63 percent over 2010 models * Quieter operation * High - pressure (30,000 psi / 2, 000 bar) Piezo - actuated fuel system for greater fuel efficiency, improved performance and reduced emissions * Exhaust brake system that enables controlled vehicle slowdown on downhill
grades without actuating the brakes * Selective catalytic reduction after - treatment system using diesel exhaust fluid (DEF) injection to provide the best overall diesel characteristics and performance — with a range of about 5,000 miles (8,000 km) between DEF refills * Combustion and after - treatment have been optimized to provide about 700 miles (1,125 km) between diesel particulate filter regenerations — a 75 - percent improvement over the previous system and significant contributor to improved fuel efficiency, as the regeneration process requires additional fuel * B20 biodiesel capability for an alternative fueling option * Internal revisions that improve
durability
