In conjunction with the unveiling of the updated XC90 SUV, Volvo has launched its new range of upgraded and newly developed electrified engines, which will be available throughout the range of models.
First of all, the Swedish manufacturer's existing T8 and T6 Twin Engine plug-in hybrid powertrains have all been upgraded with new batteries and a cable-braked energy recovery system. Volvo claims that the PHEV T8 and T6 systems (the first 420 hp product) generate a 15% increase in battery life.
At the same time, Volvo has also confirmed that all models will soon be available with a hybrid plug-in option. This includes cars backed by the Scalable Product Architecture (SPA) and the smallest compact modular architecture used by the XC40. Currently, the CMA platform offers a plug-in hybrid T5 Twin Engine option, but a T4 Twin Engine option will be introduced at a later date.
In the coming months, Volvo will begin deploying hybrid gasoline and light-duty diesel powertrains for the XC90 and XC60. This system comes with Volvo's advanced kinetic energy recovery braking system, combined with existing internal combustion engines to create a new, integrated electrified powertrain. All hybrid hybrid models will receive the new "B" badge.
This new hybrid powertrain soft, electrified via energy recovery, offers drivers up to 15% fuel savings and emissions reductions in real driving. The new electric brake system works in conjunction with the energy recovery system and reduces fuel consumption and emissions by recovering kinetic energy during braking.
The refreshed XC90 will be available soon with the soft gasoline / diesel hybrid with B5 emblem, as well as with the hybrid model with gasoline with B6 crest. The same B5 and B6 offerings will be extended to the XC60, although the smaller SUV is joined by a B4 light diesel hybrid.
Volvo also notes that B5 models will be available with front or all-wheel drive. For now, the automaker has released the technical specifications of the B5 AWD diesel powertrain for the XC90, which includes a 2.0-liter two-cylinder turbodiesel delivering 235 hp at 4000 rpm and a torque of 480 Nm from 1,750 to 2,250 rpm.
The mill is coupled to an AWF8G55 eight-speed automatic and is good for a sprint time of 7.6 seconds; Maximum speed of 220 km / h. Meanwhile, the electric motor provides 14 additional PS and 40 Nm to the transmission if necessary.
Volvo has been developing its version of the kinetic energy recovery system (KERS) since 2011 and differs from the configuration of the belt start generator used in other light hybrids, in which regenerative braking is used to load the training battery.
In previous prototypes, Volvo's KERS is mounted on the rear axle and is based on a carbon fiber steering wheel. During braking, the energy is transferred to the steering wheel by a wire brake recovery system, which quickly turns up to 60,000 rpm. When the car starts to move, steering wheel rotation is transmitted to the rear wheels through a specially designed transmission, which can boost up to 80 hp.
