You know what?
Drive-E in the “E” includes three concepts, Efficient power (high power), Electrification (reserved for future, battery power), Environment (Environmental Friendly) . Drive-E powertrain revolutionary breakthrough lies in the number of cylinders, displacement constraints on the performance of smaller displacement, higher performance, lower emissions, and environmental protection to achieve the perfect balance of power, but also both smart innovative features and electrification.
engine technology
In early development, Volvo engineers to consider how to make while smaller displacement cars have more power without losing the harshness naturally aspirated engine. First of all to increase the power, turbo is a good choice, but the turbo lag is inevitable, so in order to solve this problem, Volvo’s engineers used mechanical supercharger and twin turbocharging technology, in the case of low speed supercharger operates at high rotational speed of the turbocharger before entering the work, which only increases the power, but also can be well controlled turbo lag phenomenon occurs, so that operation of the engine closer to the naturally aspirated.
and the Drive-E biggest feature is the use of modular production, 70 percentage of petrol and diesel engine parts are shared, thus the cost It can be controlled. Therefore Drive-E T5 and T6 in the overall engine is mostly the same, only T6 engine uses a larger size turbocharger and a supercharger.
Transmission Technology
Volvo Drive-E is used in Japan from an 8-speed Aisin manual gearbox, but this 8AT gearbox is one of only two on the market today tapped 8AT. After carrying this 8AT gearbox transmission ratio to enhance the coverage percentage of 23, each gear arrangement is also more closely, fuel economy is also better.
