Volvo’s redesigned VN
Volvo Trucks North America unveiled its new VN series of Class 8 highway tractors. The goal of the three-year, $190 million development was to make improvements in productivity, aerodynamics, driver safety and comfort, the company said. The effort led to the redesign of more than 1,000 parts that comprise the previous VN model.
In the area of aerodynamics, the new VN has a drag coefficient that is 3.2 percent less than the previous model – an improvement that can result in as much as a 1.5 percent improvement in fuel economy. Volvo also has made some changes that, when taken with other changes made in recent years, make the new VN up to 1,500 pounds lighter than the original VN launched in 1996. Among the areas where Volvo saved weight were the frame rails, front air suspension system, gear reduction starter, power steering and various brackets.
Meeting the challenge of the October 2002 emissions requirements was one of the goals of the redesign. “We weren’t going to try and make a new engine fit into a chassis it was never designed for, under an old hood with a grill opening that is too small for the cooling requirements and so on,” says Susan Alt, vice president of marketing, Volvo Trucks North America.
By redesigning the entire package – cab, chassis and engine – Volvo was able to adjust for some negative aspects of the Environmental Protection Agency mandate. For example, the company was able to counter the additional weight of a compliant engine with weight reductions elsewhere in the vehicle.
The improvement in aerodynamics results from a number of changes, including:
- A lower profile and wider body;
- A shorter wheelbase that reduces the trailer gap by as much as 12 inches;
- Reduction of other gaps between cab and trailer
- A new headlight design;
- A new front bumper that manages airflow under the truck;
- Flared fenders that minimize airflow across the vehicle;
- New mirrors; and
- New splash shields that reduce dirt buildup.
Volvo expects to gain reliability improvements from several changes in VN design, including:
- A new engine cooling system that includes a high-performance fan for maximum cooling;
- Air intakes on each side of the hood to balance intake and dissipate heat rejection;
- An air charge projection system that uses air pressure to determine vehicle load;
- A new hood and mounting system that reduces vibration;
- A new environment control module that allows a driver to program an automatic shutdown order for electrical appliances so that battery power never drops below what is needed to start the engine;
- A new gear reduction starter that is less susceptible to wear;
- New electronic architecture based on a data bus that cuts down on wiring; and
- A three-piece bumper that protects the input shaft from contaminants during harsh driving conditions.
A major emphasis in the VN redesign was providing easy accessibility to serviceable areas and designing components that are more durable and cost less to repair. Improvements include:
- Accessible service areas located on the “cool side” of the engine – away from the exhaust gas recirculation system;
- Two-piece engine cover;
- Three-piece bumper that is easy to remove and replace and provides better access to the engine compartment;
- New fairings that were designed to be completely removable without tools for access to frame-mounted equipment;
- New headlamps that are less prone to damage and allow individual replacement of low beams and high beams;
- A new cowl with spring clamps improves access to the windshield wiper assembly;
- New side mirrors that require only the glass to be replaced if broken;
- Injection-molded splash shields are easier to remove and provide better accessibility to the engine compartment;
- A hood release located under the steering column so it is accessible from both inside and outside the cab;
- V-ribbed belts on all front-end accessory drivers ensure longevity and can be changed in less than 6 minutes;
- A radiator that has a pivot design allowing cores to be cleaned without draining the coolant;
- A new climate control system that includes additional aluminum tubing to protect sensitive fluids from leaking. Also, more powerful evaporators and increased filter sizes extend service intervals. And new electronic controls reduce maintenance by eliminating cables; and
- An oil change interval that is unchanged.
Driver comfort and safety
Volvo engineers worked with interior designers and ergonomic experts on the redesign of the cabin area. Improvements include:
- A wraparound dash designed to minimize stress and fatigue and allow for more rocker switches for aftermarket accessories;
- An automotive-inspired instrument cluster that includes a primary display computer limiting what systems the driver can control while the vehicle is moving;
- A larger message center located directly in front of the driver and controlled through the windshield wiper control stalk on the steering column;
- A new steering wheel that allows the driver to control lights and the radio from the steering wheel for improved safety;
- New electronic climate control for more precise temperature settings and better airflow;
- A new driver’s seat;
- New electrically heated side mirrors that improve visibility;
- An optional remote keyless entry system;
- New interior amenities; and
- Sleeper upgrades
The Volvo VN will be available from dealers in November as requirements for lower-emission engines take effect.
Diesel smoke opacity tester
Using OTC’s Smoke Check 1667 Diesel Smoke Opacity Tester fleet personnel can immediately determine if a diesel will pass sate standards and interstate emissions programs. It is portable and can perform accurate tests even in windy conditions with one operator, the company says. A digital LCD screen walks users through each step, and a verifying printout of test results is produced.
Workbench, work tables
Akro-Mils’ new line of work centers includes steel work benches and work tables outfitted with storage bins, hanging systems and cabinets. The work benches are offered in 30 x 60-inch or 30 x 72-inch desk sizes, with optional features. The work surface is available in 11-gauge steel or 1.25-inch finished oak with rounded edges. Both steel and wood work surfaces accommodate a vise or clamps. The fixed-height model stands at 34 inches and the adjustable-height model has range of height settings from 30 to 40 inches.
For applications requiring mobile workstations, heavy- and medium-duty work tables come with two fixed and two swivel casters. The heavy-duty model features a welded-steel frame with a steel-reinforced hardwood work surface. The table is 24 inches long x 48 inches wide with nine adjustable height settings from 36 to 48 inches. The medium-duty work table measures 24 inches long x 48 inches wide with a fixed 36-inch height.

A package that includes training, technical support and next-day shipment of replacement units is available.
Extended, crew cab options for M2
Freightliner Trucks last month introduced Extended Cab and Crew Cab models for its new Business Class M2 line of medium-duty and vocational trucks. Production of the optional Extended Cabs and Crew Cabs will begin in the fourth quarter of 2002, and customers can order the cab options from dealers starting in October.
The M2 Extended Cab measures 132 inches from bumper to back-of-cab (BBC) – 26 inches longer than the standard day cab models. It can seat four comfortably and is designed for applications in towing, specialty hauling, emergency rescue and ambulance service, or in other vocations where extra capacity and storage are needed.
Buyers can specify the Extended Cab with or without rear seats. The two optional rear jump seats face forward and fold up when not in use. In place of rear seats, a 24-inch-wide bunk that meets DOT specifications is available for sleeper applications.
The Extended Cab has 460 square inches of tinted glass on each side. As an option, the bunk windows can tip out for improved ventilation. The one-piece, 882-square-inch rear window offers unobstructed visibility.
The M2 Crew Cab measures 154 inches BBC and offers seatting for up to six people, including the driver. Crew Cabs are designed for applications in fire and rescue, various service applications, moving vans and RV hauling.
A variety of seating options are available, including air-suspended or non-suspended seats and bench seats for both the front and the rear of the cab. Both the front and rear doors of the Crew Cab have been redesigned and offer improved entry and exit – especially important for fire and rescue workers wearing bulky protective gear.
In a related development, production of the Business Class M2 truck line began in June at Freightliner’s Mount Holly, N.C., truck plant. Freightliner is gradually replacing its original Business Class line with the new M2.
