Kenworth unveils aerodynamic T680

Kenworth says its engineers spent five years working on the T680’s design, saying it’s the most aerodynamic tractor the company has ever built.

Kenworth’s new Model T680 features a sculpted full-height roof, optimized bumper and hood, full-height side extenders, cab/sleeper-to-fairings closeout panels, chassis fairings extenders and flush-mounted lighting.

Compared with similar models, it has a 10 percent enhancement in aerodynamics, 65 percent more storage capacity, a 50 percent larger windshield, 40 percent less interior noise, 30 percent larger door openings and best-in-class forward lighting, the truck maker says.

The T680 is designed to maximize performance in line-haul, pickup and delivery and regional operations. Available with a new 76-inch sleeper or as a daycab, the T680’s standard engine is the 2.9-liter Paccar MX. The Cummins ISX15 is optional.

The T680’s new 76-in. sleeper is integrated with the truck’s cab. It’s 96 inches wide with a high ceiling, 60 cubic feet of storage and a full-height wardrobe cabinet.

The truck’s cab is 83 inches wide with 23 inches of space between the seats. Premium Diamond VIT and Vantage trim levels are available for the interior, with two color options of Sandstone Tan and Slate Gray.

Executive Editor Jack Roberts took the new Kenworth for a test drive in Louisville, Ky. Here’s some of what he had to say about the tractor’s interior:

My test-drive truck was a regional-cab tractor with an MX13 engine and an Eaton 10-speed manual gear box. Kenworth’s all-new seat design features an advanced air-suspension system and multiple lumbar and recline adjustments. Combined with the new tilt/telescoping steering wheel, the overall design makes it easy to get comfortable quickly.

Another nice touch is the redsigned dash board. If there’s a theme here, it has to be simplicity. Truck dashes have become crammed with competing information systems that can be difficult and distracting to operate, but everything in the T680’s cab is laid out logically and ergonomically. Critical engine and vehicle data are arranged in the new A cluster directly in front of the driver, with auxiliary controls and switches within easy reach on the center cluster. Toggle switches glow green when activated to allow drivers to tell at a glance if they’re on.

Cummins 15-liter natural gas engine

Cummins is developing a 15-liter spark-ignited natural gas engine for on-highway applications. The ISX15 G will be based on the ISX15 diesel, and its three-way catalyst will not require exhaust aftertreatment. Expected to be in limited production in 2014, the engine will run on compressed natural gas, liquefied natural gas or biomethane.

Cummins also unveiled a prototype of its advanced waste heat expander. The system can reduce fuel consumption by up to 6 percent, the company says, delivering fuel savings of between $4,000 (typical heavy-duty cycle) and $40,000 (typical high-horsepower cycle), depending on the application and engine power.

Ecopia fuel-efficient tires

Bridgestone’s Ecopia fuel-efficient tires are designed to reduce overall tire wear costs up to 29 percent by fostering retreading. Five tires in the Ecopia series will be complemented with equivalent Bandag FuelTech retreads to reduce life cycle costs.

The line’s NanoPro-Tech polymer technology helps control particle movement by bonding the carbon black in the tread, which reduces flexing and related energy loss. The Fuel Saver sidewall compound runs cooler, saving more energy, the company says. In addition, the IntelliShape sidewall, found in both the M710 Ecopia drive radial and R197 Ecopia trailer tire, contain less bead filler volume, which reduces tire weight, improves fuel economy and conserves resources.
