The Volvo ReCharge range on a full battery will be 62 mile (100 km), before the four-cylinder 1.6-liter flex-fuel engine kicks in to power the car and recharge the battery.
For a 150 km (93 mile) drive starting with a full charge, the car will require less than 2.8 liters of fuel, giving the car an effective fuel economy of 124 mpg or about 1.9 l/100km.
The combustion engine starts up automatically when the battery pack reaches a 30% state of charge.
A full charge when plugged into a standard power outlet takes approximately 3 hours, but according to Volvo even 1 hour plugged-in gives the car a 50% charge.
Press release: GROUNDBREAKING PLUG-IN HYBRID – THE VOLVO RECHARGE CONCEPT – UNVEILED AT FRANKFURT MOTOR SHOW
* Plug-in hybrid with battery-only range of over 60 miles
* 66 per cent lower CO2 emissions than best hybrids available today
* 1.6 Flexifuel engine provides backup and recharge power
Volvo is unveiling an innovative plug-in hybrid at the Frankfurt Motor Show. The ReCharge Concept is a specially designed Volvo C30 with individual electric wheel motors and batteries that can be charged via a regular electrical outlet. When fully charged the Volvo ReCharge Concept can be driven approximately 62 miles on battery power alone before the car's four-cylinder 1.6 Flexifuel engine1 is needed to power the car and recharge the battery. The concept car also retains the Volvo C30's lively and sporty drive thanks to an acceleration figure of 0-62mph in 9 seconds and a top speed of 100mph.
"This is a groundbreaking innovation for sustainable transportation. This plug-in hybrid car, when used as intended, should have about 66 percent lower emissions of carbon dioxide compared with the best hybrid cars available on the market today. Emissions may be even lower if most of the electricity comes from CO2-friendly sources such as biogas, hydropower and nuclear power. A person driving less than 60 miles per day will rarely need to visit a filling station. Also, thanks to the excellent electrical range from a fuel consumption angle, the Volvo ReCharge Concept is exceptionally kind to the car owner's wallet," commented Magnus Jonsson, Senior Vice President Research & Development at Volvo Cars.
Operating costs are estimated to be about 80 percent lower compared to a similar petrol-powered car when using battery power alone and even drivers who cover more than the battery-only range will benefit from the ReCharge Concept. For a 150km (93 mile) drive starting with a full charge, the car will require less than 2.8 litres of fuel, giving the car an effective fuel economy of 1.9 l/100km (124mpg).
The only extra cost will be the electricity used during charging. The Volvo ReCharge Concept can be charged at any regular electric plug socket at convenient locations such as at home or work and a full recharge will take three hours. However, even a quick one hour charge provides enough power to cover just over 30 miles. During a journey the combustion engine starts up automatically when 70 percent of the battery power has been used up. However, the driver also has the option of controlling the four-cylinder Flexifuel engine manually via a button in the control panel. This allows the driver to start the engine earlier in order to maximise battery charge, for instance when out on a motorway in order to save battery capacity for driving through the next town.
An electric motor at each wheelThe Volvo ReCharge Concept combines a number of the latest technological innovations into a so-called "series hybrid" where there is no mechanical connection between the engine and the wheels.
* The battery pack integrated into the boot uses lithium-polymer battery technology. The batteries are intended to have a useful life beyond that of the car itself.
* Four electric motors, one at each wheel, provide independent traction power.
* Four-cylinder 1.6-litre Flexifuel engine drives an advanced generator that efficiently powers the wheel motors when the battery is depleted.
"There is a considerable difference between the Volvo plug-in hybrid and today's hybrids. Today's hybrids use the battery only for short periods to assist the combustion engine. Volvo's solution is designed for most people to run on electric power all the time, while providing the extra security that comes with having a combustion engine as a secondary source of electrical power," says Ichiro Sugioka, project manager for the Volvo ReCharge Concept.
