Mack unveiled aerodynamic enhancements to its on-highway Pinnacle that can increase fuel efficiency by up to 12.5 percent, the company says.
New roof fairings and chassis fairings headline the new aero features. The roof fairings are available on the 70-in. model high-rise sleeper and the 60- and 70-in. model mid-rise sleepers. The chassis fairings are longer and lighter and offer easier installation, the company says. Two new aesthetic options – a one-piece windshield option and a Grand Touring trim level – are also available.
