Volvo XC90 T8 Plug-in Hybrid — Just When You Thought You Couldn’t Be Amazed

The Volvo XC90 T8 is an outstanding luxury SUV. Its stylish appearance and seven comfortable seats make it ideally suitable for those who like full-size SUVs. However, in comparison with the other luxury SUVs, the XC90 T8 has one significant difference. When they had to choose from two options – performance or fuel economy – they chose both! The Volvo XC90 T8 has a ybrid vehicle. They had to make the SPA platform (Scalable Product Architecture platform) which will support the Drive-E hybrid powertrain without compromising the SUV’s comfort or performance. The XC90 T8 is a plug-in hybrid electric vehicle whose powertrain consists of a powerful gasoline four-cylinder engine and an electric motor placed above the rear axle. But, what they did with the battery pack is brilliant.

Structural Advantages of SPA Platform

Since the Volvo XC90 T8 is equipped with a 65-kW battery pack, if they haven’t built the SUV from scratch, they would have to alter the cabin and the layout in order to pack everything inside the body. Thanks to the SPA platform, the batteries are nested inside the central tunnel. Having a heavy battery pack placed at the center of the vehicle and at the lowest point possible, aside from the fact that the interior wouldn’t be less comfortable, the XC90 T8 will be more stable and easy to handle.

Volvo XC90 T8 Plug-in Hybrid Powertrain

Stability is what the SUV needed. It’s powered by a plug-in hybrid powertrain which mates the 2.0-liter four-cylinder Drive-E engine and an electric motor and which deliver impressive amount of power. The Drive-E engine has been improved for the Volvo XC90 T8 – it got a turbocharger and a supercharger, so now it delivers 318 horsepower and 295 lb-ft of torque. The electric motor delivers its 82 horsepower and 177 lb-ft of torque to the rear wheels. The overall power output of the Volvo XC90 T8 is 400 horsepower and 472 lb-ft of torque. The powertrain is paired with an eight-speed automatic transmission which comes with shift-by-wire feature. The Drive-E engine is nested under the hood, so with the centrally-located battery stack and the electric motor at the rear axle, the SUV has great weight balance.

What Is CISG and Why Do I Need It?

Aside from the 318-horsepower four-cylinder engine and the 82-horsepower electric motor, the Volvo XC90 T8 has yet another generator. It’s called CISG, which stands for the crankshaft-mounted starter generator. This is, actually, a 34 kW (46 horsepower) electric generator, which is used as a starter motor that harmonizes the work of the gasoline engine and the electric motor when changing driving modes. Occasionally, when needed, it can deliver additional 111 lb-ft of torque.

Volvo XC90 T8 Fuel Economy, Extremely Low Emissions and Surprising Performance

The Volvo XC90 T8 returns 59 MPGe. Although it’s the SUV’s fuel economy estimate based on the European driving cycle (NEDC), the efficiency of the 2015 XC90 T8 in real conditions would still be great. Using the same test, it’s been discovered that the SUV has incredibly low CO2 emissions — 59 g/km (approximately 95 g/mile). As for the performance, such a green vehicle isn’t exactly expected to have fire in its exhaust pipes. We’re accustomed to make a compromise and be modest in our expectations of a green vehicle. The Volvo XC90 Twin Engine SUV is a luxury full-size SUV with a plug-in hybrid powertrain and it can reach 62 mph from a standstill in 5.9 seconds.

Driving Modes

The Volvo XC90 Twin Engine SUV has five driving modes. Its plug-in hybrid powertrain can be adjusted to deliver what’s needed in any particular moment.

The default Hybrid mode will automatically determine which source of power is the best for use at the moment. Combining the Drive-E gasoline engine and the electric motor will result in the aforementioned incredible fuel economy.

With Pure Electric mode, the SUV uses the power stored in the batteries and starts the internal combustion engine only if necessary. In the all-electric mode, the SUV can travel 25 miles when the batteries are fully charged.

The Power mode uses the best of both the worlds. When in this mode, the XC90 T8 will use the electric motors ability to instantly deliver a lot of torque, while the Drive-E engine helps in higher revs.

The use of the AWD mode, which delivers the hybrid setup’s power to the all wheels, is activated manually. This way the SUV spares the energy and uses it when necessary.

The Save mode will preserve the level of energy stored in the battery pack. If the level is low, the Drive-E engine can charge the battery to the desired level.
