Press Release / May 12, 2014

Waste, sanitation and energy recovery operator Solvi Group has begun operation of Volkswagen Constellation 17.280 6x2 refuse truck chassis equipped with Bosch Rexroth-developed HRB (hydrostatic regenerative braking) hydraulic hybrid drive.

The technology transforms the kinetic energy released during braking into hydraulic energy by pumping hydraulic fluid into a hydraulic accumulator which is later released to assist acceleration.

The technology is particularly suitable for stop-and-go operations. A sustainable and economical system, hydraulic hybrid drive reduces fuel consumption while improving acceleration.

In garbage collection operation in the city of Rio de Janeiro, a 25 percent reduction in fuel consumption has been realized.

Simple in operation and low maintenance, hydraulic hybrid drive offers a lower purchase costs over electric hybrids. The hydraulic accumulator is more responsive, without the weight and costs of batteries.

In application, a savings of roughly 745 liters (197 U.S. gallons) of diesel per month was realized in two shift operations averaging 160 miles. In financial terms, approximately US$1500 was saved per month.

Environmentally, the hydraulic hybrid technology utilized in the Volkswagen 17.280 reduced CO2 emissions by nearly 2 tons per month, which adds up to 23.5 tons annually.

Solví has a fleet of over 800 trucks of which 95% of Volkswagen trucks. Over the 17 years that Solvi has partnered with Volkswagen Trucks, Solvi have developed seven prototype trucks in conjunction with the Resende, Brazil-based truckmaker. The relationship began in 1995 with the purchase of Volkswagen 16.170 medium trucks. From 2011, Solvi began ordering Volkswagen’s purpose-designed 17.250 refuse chassis.

Paccar has had a system like this in place for years, no?

A few years ago hybrid vehicles were all the rage, everyone rushed to the market with one system or another, now the noise has died down and it's back to business as usual. I think with all the emission mumbo jumbo fleet owners are hesitant to take on yet another new (and possibly flawed) technology.

its pretty cool,,,and i guess ok for city work,,,but ill take the DM600 over it.lol.bob

Brazil is one of the few energy independent countries in the world. With almost all of the vehicles made there running on Sugar based Ethanol and bio diesel. It is a requirement in Brazil that all vehicle manufacturers build alternate fuel, energy efficient vehicles. Brazil is the seventh largest auto maker in the world, and has been using alternate fuel vehicles since the late 70's so VW , Solvi and Brazil working together is not surprising.
