GWM Brasil presented DHT hybrid technology that will equip the brand's vehicles

GWM Brasil presented during an online event this Tuesday (21) the details of its DHT (Dedicated Hybrid Technology) hybrid technology, which will equip the vehicles that the brand intends to launch on the Brazilian market from the end of this year.

The DHT GWM system is the main technology responsible for the company's global growth and will soon be in Brazil to show local consumers why it is the most efficient hybrid solution on the market. One of its biggest differentiators is the ability to give the driver a real experience driving an electric vehicle.

“While in a conventional hybrid vehicle the electric motor only serves as support for the combustion engine, in the DHT GWM system it is the electric motorization that is the main character, leaving the combustion engine only as support when necessary”, explains Oswaldo Ramos, Chief Commercial Officer of GWM Brasil.

The DHT GWM system is always applied to the LMN platform, which was developed especially to give rise to GWM's new electrified vehicles. The technology consists of a 1.5 turbo engine, a double electric motor (called Dual Motor) and a pair of fixed gears that connect the combustion engine to the wheels.

 The Dual Motor has three functions in this system: transmitting movement directly to the wheels, recharging the hybrid battery and, in conditions of high torque demand, assisting the combustion engine by generating additional torque.

Instead of using a traditional gearbox with several gears, the combustion engine of the DHT GWM set uses just two gears: one is intended for use at high speeds and the other for medium speeds, always working in conjunction with the Dual Motor. . For low speeds, the system favors driving with the electric motor, which can also operate in some medium speed situations.

Another feature of the DHT GWM is the feature that allows the combustion engine to be used as a generator, just to recharge the battery, which in turn will power the electric motor that generates traction for the wheels. In this situation, the combustion engine always works at a maximum efficiency speed, reducing fuel consumption when it is started.

Due to this innovative concept, the DHT GWM offers unique advantages for a hybrid vehicle:

1) High performance without giving up low consumption: electric driving reduces fuel consumption and also helps deliver figures of up to 483 hp of power and 762 Nm of torque, with accelerations from 0 to 100 km/h in up to 4,8 s.

2) Perfect adaptation between urban and highway use: it provides low consumption with high performance in both driving cycles, in addition to enabling electric driving even on highways.

3) Compact size and low weight of the powertrain: the integrated double gear allows a greater range of use of the powertrain, in addition to favoring weight and size reduction.

4) Low noise and vibration levels: this is possible thanks to the transmission with just two gears and the offer of electric driving for longer than most competitors in the segment.

5) Real electric vehicle experience: the system makes it possible to reach a maximum speed of 140 km/h in EV mode and up to 200 km of purely electric range, in the case of the plug-in version, in addition to the use of the electric motor even at low levels of battery thanks to generator mode, which uses the combustion engine to supply electrical energy.

The DHT GWM system allows three versions of hybrid models to be offered: conventional hybrids (HEV), plug-in hybrids (PHEV) and plug-in hybrids with an extra electric motor on the rear axle (PHEV P4).

The HEV uses the 1.5T+DHT130 powertrain, consisting of a 1.5 turbo combustion engine and a Dual Motor that generate between 243 hp and 393 hp (179-289 kW) of power and 530 to 570 Nm of torque for the front axle, with acceleration from 0 to 100 km/h between 8,0 to 6,5 s.

The PHEV is equipped with this same technical configuration, but adds a larger battery, which allows an electric range of up to 200 km.

The PHEV P4 uses a 1.5T+DHT130+P4 powertrain, which adds an extra electric motor to the rear axle, resulting in a maximum power of between 393 hp and 483 hp (289-355 kW), torque of 762 Nm and acceleration of 0 to 100 km/h in 5,0 to 4,8 s, with up to 180 km of electric range.

By having an extra engine, the PHEV P4 also provides the AWD All-Terrain feature, a permanent four-wheel drive system that has an intelligent division of torque between the axles: they can vary from 100% at the front to 100% at the rear, passing through any proportion that the set deems necessary.

This distribution of torque between the axles is automatic and is determined depending on the level of road grip and the dynamic stability of the vehicle. In this way, the AWD All-Terrain can combine the best off-road performance on dirt roads with greater grip and stability on dry or wet asphalt surfaces. Another AWD All-Terrain benefit is the ability to climb slopes of up to 65% incline.

Currently, the DHT GWM system powertrains are already being tested in Brazil so that they can adapt to the driving conditions in Brazilian territory and to meet the needs and preferences of the Brazilian consumer. One of the first models to adopt DHT GWM in Brazil will be the Haval H6.
