Voyah Electric, Extended Range, Slightly Confusingly The standard all-electric Dream comes with an 82kWh battery and a claimed range of 475km. If you're someone who constantly worries about running out of battery (we all do, right?), the extended version with a 108.7 kWh battery offers a range of 605 kilometers. The extended-range version uses a 1.5-liter turbocharged gasoline engine whose sole purpose is to power the 25.57-kilowatt-hour battery. This hybrid approach promises an all-electric range of only 82 kilometers, but with a range extender, the range can be up to 750 kilometers. However, there is an interesting point. The pure electric version uses the CLTC test cycle measurement results, while the extended-range version participates in the WLTC test process. Why do you ask? Well, CLTC is known for its optimism when it comes to results—a dreamer, you could say.
