Peterbilt’s ’07 medium-duty lineup

Peterbilt has unveiled a wide-ranging all-new product lineup, complete with upgrades, replacement models, and even a handful of completely new aerodynamic and medium-duty trucks. The new “fuel efficiency lineup” represents
“the largest product development investment in the company’s 70-year history.”

The company may have felt compelled to overhaul its offerings because many current models have radiators and underhood compartments too small to accommodate new ’07 engines. The new trucks will cost between $6000-$9000
more due to the new motors and the cost of packaging them in a Peterbilt chassis.

The new 330 and 340, being built at Paccar’s plant in St. Therese, Que., join the 335 in the company’s medium-duty lineup. The lightweight 330 comes in a class 6 for GVW up to 26,000 lb. It can be spec’d with hydraulic brakes and low-profile tires to allow operation by a non-commercial driver. The 340 comes in 33,000-lb GVW. Both will be available this summer.

The new aerodynamic Model 387 day cab and Model 384, which join the 387 and the 386, round out Pete’s aero truck lineup. The new 387 day cab, for tanker and regional-haul applications, is available in medium and long-length BBC and optimized front-axle placement for maneuverability and weight distribution. The 384, with 116-in. BBC and set-back front axle, is offered as a day cab or with the full range of detachable Unibilt sleepers. The truck allows 50 degrees of wheel cut and decreases turning radius by 12 in.

The traditional Model 388 and 389, which replace the 378 and 379 respectively, retain Peterbilt’s trademark design but improve on aerodynamic performance and serviceability. Both trucks have all-new hoods with
anti-blow-down locking mechanisms, a new grille, and new fender reinforcements. Innovative headlamps and aero-style mirrors are said to provide greater visibility and reduce drag by as much as 40%. The new, lighter-weight cooling system accommodates higher-horsepower ’07 engines. Both trucks also offer a fuel-efficiency package — contoured roof fairing, oval shaped cab-mounted exhaust, aerodynamic air cleaners, and streamlined tool and battery boxes with contoured bumper and underbody fairings.

The vocational 367 and 365 take over for the 357 short- and long-nosed versions, both available with set-forward and set-back front axles. The 367 will also be available in a special heavy-haul configuration that features a high-capacity cooling system.
