Insights into the development of the Volkswagen Golf 8 GTI chassis
The Volkswagen Golf 8 GTI introduces a new driving dynamics control system.
Due on site in the third quarter of 2021, the Volkswagen Golf 8 GTI has a lot to do with over 14,000 previous generation Hot Hatch sales in South Africa.
The latest version of the performance hatch is more powerful and technically sophisticated and has the well-known 2.0-liter turbo gasoline engine EA888 with 180 kW and 370 Nm torque, which transfers the power to the front axle via a seven-speed dual clutch transmission. He sprints from 0-100 km / h in 6.4 seconds. Dynamic chassis control with variable shock absorbers, as well as dynamic indicators and a panoramic sliding roof, are available on request.
If we delve a little deeper into the development of the chassis, according to Volkswagen, the engineers have focused on improving stability, precision and cornering grip, while also improving the Everyday convenience of the Golf 8 GTI.
“The Golf GTI has always stood for pure driving dynamics,” says Karsten Schebsdat, Volkswagen Head of Driving Dynamics, Steering and Control Systems.
“Few other vehicles in this category offer a similarly finely tuned balance between sportiness and comfort. Thanks to the combination of a new chassis setup plus torque-sensing limited-slip differential (VAQ) and Vehicle Dynamics Manager, we were able to raise the outstanding overall performance of the Golf 8 GTI to an even higher level. “
What’s new under the skin of the GTI?
Changes to the chassis setup of the new performance tailgate are intended to increase precision and driving stability. The front suspension strut has newly configured wishbone bearings and revised damping hydraulics. The springs and buffers have also been reconfigured to achieve a spring rate five percent higher on the front axle than on the Mk7 GTI.
A new, stiffer aluminum subframe is almost three kilograms lighter than its predecessor, while the multi-link rear axle has a new wheel mount, wishbone bearings and spring adjustment, as well as newly designed auxiliary springs.
On the rear axle, the spring rate has increased by 15 percent compared to the Mk7, the damping bearings are new, as is the damping hydraulics.
In its latest iteration, the Golf 8 GTI presents a new driving dynamics control system – the Vehicle Dynamics Manager (VDM). According to Volkswagen, the system combines the electronic stability control (ESC) with the electronic differential locks (XDS) and the optional adaptive damping system DCC. In order to enable agile and precise handling, individual wheel damping takes place 200 times per second, says Volkswagen.
The New The Golf 8 GTI is now equipped with an electronically controlled, torque-dependent limited-slip differential as standard.
When used on the racetrack, the ESC intervention can be adjusted in two stages. In ESC Sport mode, the ESC thresholds and the ASR slip thresholds are increased in order to reduce the intensity of intervention.
In the ESC Off mode, ambitious drivers can completely deactivate ESC.
The available adaptive chassis control (DCC) reacts continuously to the road surface and the driving situation. For the first time, the transverse dynamic components of the DCC chassis in the new GTI are coordinated and further optimized by the VDM.
The driver can use the driving mode settings to influence the reduction in body movements as required.
The required damping is calculated for each wheel and adjusted to the four dampers within fractions of a second. In this way, DCC in connection with the VDM can offer the highest level of driving comfort and optimum driving dynamics.
In the latest DCC generation, the vehicle setup can be expanded in individual mode in order to go beyond the existing range of fixed modes Comfort, Eco and Sport, says Volkswagen.
In the comfort setting, the body is largely “decoupled” from the road, thus increasing driving comfort. By selecting the sport mode, there is an extended setting range with maximum damping for minimized body movements.
But does it all add up to a balanced car? We are I’m looking forward to try out the new Golf GTI this year.
