Volvo introduces Twin Engine plug-in hybrid technology in XC90

Volvo has released more details on the XC90 T8 plug-in hybrid model.

By building on the new modular Scalable Product Architecture (SPA) platform and successful Drive-E petrol powertrain, the company has created a roomy 7-seater SUV that delivers 400hp/640Nm combined with ultra-low emissions of 59g/km TBC.

“The XC90 T8 is a plug-in electric car, hybrid car and high-performance car rolled into one,” says Dr Peter Mertens, Senior Vice President Research and Development of Volvo Car Group. “The Drive-E engines already offer highly competitive performance versus the competition. The T8 takes it further into a leading position.”

Using either a scroll wheel on the centre console or a touchscreen on the dashboard, drivers can choose from:
 
Hybrid: This is the default mode, suitable for everyday use. Here, the vehicle will automatically alternate between drawing power from the 2-litre, 4-cylinder Drive-E engine and the electric motor to deliver the best overall fuel consumption.

Pure electric: In this mode, when the high-voltage battery is fully charged, it serves as the car’s sole energy source, powering the electric motor over the rear axle. The XC90 T8 has a range of up to 25 miles using just electricity, which covers the total distance most people drive in one day. And thanks to the regenerative braking system, this mode is super-efficient in the stop-and-go traffic of city environments. If more power is needed, the Drive-E combustion engine starts up automatically.
 
Power mode: Here, drivers get the combined performance of the combustion engine and the electric motor. On start-up, the SUV takes advantage of the electric motor’s superior response and instant torque curve, while the combustion engine gets up to speed. This combination offers better torque at lower revs, equivalent to that of a large displacement engine like the V8.
 
AWD: This mode offers constant all-wheel drive on demand. The advantage of being able to select AWD manually is that the driver can use it when needed, or choose to save energy for later.
 
Save: If the battery is charged, this mode allows the driver to “freeze” the battery level and save it for later use with Pure Electric drive. On the other hand, if the battery is low, the driver can use the combustion engine to charge the battery to a certain level for later use with Pure Electric drive.

A specially modified version of the 4-cylinder Drive-E petrol engine is under the hood. The Drive-E engine is enhanced in the XC90 T8 by a supercharger and a turbocharger for a total power output of 318hp and 400Nm torque.

Delivering 82hp (60kW) and 240Nm torque, the large electric motor sits on the rear axle and drives the back wheels in electric and power-boost modes.
