Clean Tech Company Protean Electric Displays Vauxhall Vivaro Plug-in Through-the-Road Hybrid-Electric Vehicle at eCarTec 2010.

- Test Vehicle in Partnership with Millbrook Proving Ground Debuts for First Time at Major International E-Mobility Show

MUNICH, Germany, October 19, 2010 /PRNewswire/ -- Protean electric, a leading global supplier of in-wheel electric motors, and Millbrook Proving Ground, one of Europe's leading vehicle test and demonstration centers, partnered to produce a practical and class-leading light commercial vehicle with plug-in hybrid and electric vehicle operational capabilities. The Vauxhall Vivaro through-the-road hybrid (TTRH) test vehicle is on display at eCarTec 2010, 19-21 October in Munich, Germany, with Bundesverband eMobilitat in Hall B5, Stand 614.

The Vivaro is debuting for the first time at an international e-mobility show, following its UK debut at the 2010 Low Carbon Vehicle Show in September at Millbrook. The technology can be applied to many light delivery vehicles and can be offered as a conversion option for fleet operators.

"This Vivaro through-the-road hybrid vehicle demonstrates a practical, cost-effective and efficient way to retrofit a commercial vehicle into a plug-in parallel hybrid by simply adding two in-wheel motors," said Jon Meyer, chief operating officer of Protean Electric. "Fleet operators throughout Europe should be lining up for a vehicle such as this that will provide more than a 65 percent reduction in fuel usage and CO2 emissions in a typical urban drive-cycle lower than 65g/km, while enabling electric-only operation for in-city low-emission zones such as London."

Protean Electric outfitted the the Vivaro plug-in parallel test vehicle with a through-the-road hybrid conversion kit of two Protean Electric PD-18 motors attached to the rear axle of a standard front-wheel drive commercial vehicle. The system provides a torque assist of up to 1,650 Nm peak and 1,000 Nm continuous at the rear wheels. The system can also deliver regenerative braking on the rear wheels with no modifications needed to the existing front brakes while retaining the vehicle's original engine and drive system. This high level of regenerative braking allows manufacturers to use a smaller battery size or extend the range with the same battery size.

The through-the-road-hybrid retrofit allows the driver to switch between multiple operating modes: two- or four-wheel drive operation, IC engine-only drive, electric-only drive, or an electric torque assist. The test Vivaro through-the-Road-hybrid is fitted with a 21kWh battery, giving the vehicle more than 55 miles (90 km) of electrically-driven range and a measured 114 mpg (2.4 litres/100km) over the New European Driving Cycle (NEDC). The battery can be sized according to the range requirements of the user between charges, making this conversion one of the most competitive electric vehicles on the market.

The vehicle is currently going through a rigorous testing regime jointly conducted by Millbrook and Protean Electric. Work is underway on an initial Vivaro Plug-In Parallel Through-The-Road-Hybrid test fleet for select fleet customers, scheduled early in 2011.
