In a statement today, the company said the 2012 Volvo V60 Plug-in Hybrid is the result of its close cooperation with Swedish utility company Vattenfall.
The Volvo V60 Plug-in Hybrid promises a fuel economy of 1.9 L/100 km (123.8 mpg US or 149 mpg Imperial) with carbon dioxide emissions below 50 g/km.
The V60 Plug-in Hybrid features a five-cylinder 2.4-liter D5 turbodiesel, which produces 215 horsepower and maximum torque of 440 Nm. The turbodiesel drives the front axle, while the rear axle has ERAD (Electric Rear Axle Drive) in the form of an electric motor producing 70 horsepower, which receives its power from a 12 kWh lithium-ion battery pack. The car features a six-speed automatic transmission.
The V60 Plug-in Hybrid can be driven on diesel power alone, as a diesel-electric hybrid, or as an electric-only car – technology that no other manufacturer can currently offer. The driver chooses the preferred driving mode via three buttons on the instrument panel: Pure, Hybrid and Power.
In Pure the car runs only on its electric motor as much as possible. If the battery has been recharged using electricity from a renewable source, the driving range is up to 50 km (32 miles) with zero emissions of carbon dioxide. Battery range varies with terrain, climate and driving style.
Hybrid is the default mode whenever the car is started. The diesel engine and electric motor interact to provide the optimal balance between driving pleasure and low environmental impact. Emissions of CO2 (EU Combined) are 49 g/km, corresponding to diesel fuel consumption of 1.9 l/100 km (123.8 mpg US or 149 mpg Imperial). The car’s total range is up to 1200 km (750 miles). The driver has the possibility to key in the planned route’s distance (short, medium or long) in the car setup menu. The control system calculates the balance between diesel and electric power to obtain the lowest possible CO2 emissions for the given distance.
In Power the technology is optimized to give the car the best possible performance. The diesel engine and electric motor have a combined power output 215 + 70 horsepower and maximum torque of 440 + 200 Nm. The electric motor’s lightning-quick torque delivery contributes to the car’s 0 to 100 km/h acceleration time of 6.9 seconds.
Volvo claims the car has an overall range of up to 1200 km (750 miles), a top speed of 200 km/h or 125mph (100 km/h or 62mph in all-electric mode) and will cover the 0-100km/h (0-62mph) dash in 6.9 seconds.
Save battery power for later
The V60 Plug-in Hybrid offers the driver the option to save battery capacity in order to have enough charge for driving on clean electricity later, for instance in an urban low emission zone.
When Save For Later is activated, the car makes sure that the battery has a sufficient charge level for another pure drive. If necessary, the High Voltage Generator recharges the battery in order to maintain a sufficient charge level for another “Pure” drive.
The aim is that the Save For Later mode should secure enough battery capacity for approximately 20 kilometers drive on pure electricity.
The two-step braking system is another intelligent feature in the Volvo V60 Plug-in Hybrid. When the driver pushes the brake pedal, the system initially brakes the car by controlling the rear axle motor. This braking energy is used to regenerate the car’s battery pack.
The mechanical brakes are only activated when the situation requires more braking power than the rear axle can handle.
Recharging at home
The Volvo V60 Plug-in Hybrid is recharged via a regular power socket (230V/6A, 10A or 16A) at home or in a parking lot. The charging time depends on the level of the current. A full 10A charge takes 4.5 hours. The time is shortened to 3,5 hours with 16A, while a charge in a 6A socket takes 7.5 hours.
To get a comfortable start of the journey, the car driver has the possibility to preheat or cool the passenger compartment during the recharging process. This also means that more battery capacity can be used for powering the car.
The pre-conditioning also includes the possibility to cool the batteries. The battery pack has an ideal working temperature of 20-30°C. This means that the pre-cooling is highly important for maximizing the charging capacity and thereby the driving range on each charge. The timing is programmed via the car’s setup menu or remotely via a smart phone application.
The V60 Plug-in Hybrid has two heating possibilities. When running on electricity a PTC (Positive Temperature Coefficient) air heater is used. The car also has a Fuel Operated Diesel heater.
Smart mobile applications
On the outside the car has several additional features that emphasise its CO2-lean profile, such as lightweight wheels with exceptionally low air drag and tyres designed for low rolling resistance.
The instrument panel in the Volvo V60 Plug-in Hybrid has been modified to give the driver a full range of important information about diesel and electricity consumption, battery charge level, remaining range and so on.
It will also be possible to communicate with the car via a mobile application. This gives the owner access to a number of smart features, such as climate conditioning, both pre cooling and pre heating, a reminder to plug in the charging cable if this hasn’t been done at a certain and pre-set time for charging.[wzslider height=”400″ lightbox=”true”]
