This year marks the 35th anniversary of Volvo’s introduction of the Integral Sleeper, which the company says was the first North American conventional truck model to offer a streamlined design and a fully integrated sleeper compartment.

Caring for the environment has long been a Volvo core value, a position formalized at the 1972 United Nations Conference on the Human Environment, long before it was a trendy mainstream corporate aspiration.

“Pioneering innovations in design, fuel efficiency, driver productivity and safety have defined Volvo Trucks throughout our 90-year history,” said Magnus Koeck, Volvo Trucks North America vice president, marketing and brand management. “We’re proud of our heritage and celebrate 35 years of aerodynamic design. With the Integral Sleeper model we truly introduced a new standard, and all manufacturers quickly followed suit – a trend we continue to see today with automated manual transmissions, greater integration of connectivity services to help maximize uptime, and right-sizing of engines for improved fuel efficiency and weight savings."

The Integral Sleeper united the cab and sleeper compartments for improved aerodynamics with seamless construction that also allowed easy pass-through from the driving environment to the living space. The redefined truck design also introduced a hood that was 6 inches narrower and 6 inches lower at the front than at the cowl, to help reduce wind resistance. Integral Sleeper aerodynamics were further boosted through a full-height roof fairing, cab side extenders, chassis fairings, and trim tabs that helped air flow smoothly from the tractor to the trailer.

“Over the past year we’ve introduced the new Volvo VNR regional haul, Volvo VNL long-haul, and Volvo VNL heavy-haul tractors under the theme 'The Shape of Trucks to Come,' which also would have been very appropriate during the 1983 introduction of the Integral Sleeper, a model that inspired a design revolution for conventional model trucks,” said Koeck.

Setting the Safety Standard

Safety's another one of Volvo's core values, and Volvo became the first Class 8 truck brand in North America to designate a steering wheel-mounted driver’s side airbag as standard equipment. More recently, Volvo Enhanced Stability Technology (VEST), an enhanced stability system, was added as standard equipment for its on-highway lineup in 2007.

“Volvo aspires to zero crashes and zero injuries, helping protect drivers and all road users,” said Johan Agebrand, director of product marketing for Volvo Trucks North America. “Our global Zero Accident Vision is about helping improve safety, and mitigating these events also presents a tremendous cost savings to truck owners.”

Volvo’s July 2017 introduction of the new VNL model also brought Volvo Active Driver Assist, featuring Bendix Wingman Fusion as a standard offering. Volvo said this made it the first heavy-duty truck OEM to offer the active safety system as standard equipment, a designation also applied to the new Volvo VNR series. The system is also integrated with VEST to help drivers avoid rollover, jackknife, and loss-of-control situations on dry, wet, snow- and ice-covered roadways.

The Shift to Automated Manual Transmissions

Volvo also ushered in a shift in transmission preference in North America, as the first to market with a proprietary automated manual transmission. In just over a decade since its North American introduction, the Volvo I-Shift is now spec’d in more than 90% of all Volvo trucks built for the market. It is standard across the Volvo VNR, VNL, VNX, VHD and VAH product range.

“While we still offer manual transmissions, it’s increasingly difficult to justify their use, even for the most demanding jobs,” said John Moore, Volvo Trucks North America product marketing manager – powertrain. “We truly have an I-Shift for every application, whether it’s regional, long-haul, or even heavy loads with our 14-speed I-Shift with Crawler Gears supporting gross weights up to 225,000 pounds. Regardless of the application, the I-Shift consistently performs at its best, whether it is two hours or 10 hours into a job.”

Factory-Installed Connectivity and Beyond

Volvo Trucks today includes its connectivity hardware as standard equipment across its entire North American product range. The connectivity hardware provides access to Remote Diagnostics, which provides proactive diagnostics and monitoring of critical engine, transmission and aftertreatment trouble codes. Volvo also uses the standard onboard connectivity hardware in partnership with fleet management system providers.

Volvo’s standard, factory-installed hardware allows customers to perform software and parameter updates over-the-air with Remote Programming, which helps improve uptime and vehicle efficiency while reducing downtime costs.

“We’re in an exciting period when it comes to truck technology, and the speed of change is only accelerating,” said Agebrand. “It’s easy to get caught up in the technology revolution, but we must keep in mind the industry’s journey and the transformative designs and innovations that will continue to sculpt the shape of trucks to come.”
