TRC testing says Bullet more fuel-efficient

Independent testing provided by Transportation Research Center, Inc. (TRC) showed the Sterling Bullet is more fuel-efficient than two similarly spec’d competitors, Sterling said.

According to the company, the Bullet used between 14 and 23% less fuel than a 2008 Ford F550 with a Power Stroke diesel engine and a GM 5500C with a Duramax diesel engine during a Joint TMC/SAE Fuel Consumption Test Procedure Type II test.

The Bullet, aimed at applications such as construction, utility and municipal services, is powered by a Cummins ISB 6.7L engine the company said. It is offered as a regular cab with four wheelbases or as a quad cab with two wheelbases.
