In March 2022, the Kia EV6 squeezed out many competitors and won the throne of the European Car of the Year, in which the high-performance version of the EV6 GT model even compared to the Porsche Taycan GTS version in some performance specifications; recently, the European media actually experienced the Kia EV6 GT and revealed the secret behind the EV6 GT.
According to an interview with Albert Biermann, a consultant at Hyundai-Kia's European R&D center, The European Media noted that the original Kia EV6 development plan did not have a high-performance version. Until one day, the chairman of the Hyundai-Kia Group came to him and asked "whether it is possible to develop a product that is competitive with the American electric car", and the development plan for the high-performance version of the EV6 GT was officially launched.
The final version, unveiled with the Kia EV6, produced 430kW (585 hp) and a maximum torque of 740 Nm. Meters, from stationary to 100 km/h in just 3.5 seconds, the pure power data can already be compared with the Porsche Taycan GTS; in addition, in the film released by Kia, in the acceleration test of 400 meters in a straight line, the Kia EV6 GT beat the Lamborghini Urus, Ferrari California T, Mercedes-AMG GT and Porsche 911 Targa 4, losing to the McLaren 570S with only a slight margin. At a price of 65,990 euros, the Kia EV6 GT acceleration is quite powerful.
Power tips: Rear axle motors use dual inverters
Kia EV6 GT's amazing acceleration performance makes people wonder how it is done, especially the EV6 GT and the general version of ev6 in the battery composition, motor number is not much different. Albert Biermann explained that under the condition that the body structure and chassis space have been predetermined, Kia has greatly increased the output of the rear axle motor through the technology of "dual inverter".
The main function of the vehicle inverter is to convert the high-voltage direct current in the battery into alternating current for electric motors, and in general, the energy converted by 1 inverter to consume 1 motor (or the whole vehicle); with the 77.4kWh battery pack equipped with the Kia EV6 GT, the maximum output of a single three-phase inverter is 160kW, and the Genesis GV60, which also uses the E-GMP platform of the Group, is the highest output of 160kW.
In order to realize the potential of the EV6 GT, Kia developers will be two three-phase inverters, both supplied to the rear axle of the electric motor, under the dual inverter support, the rear axle output can reach a maximum power of 270kW, plus the front axle of 160kW, so that the vehicle output of 430kW (585 horsepower).
Theoretically, the Ioniq 5 N will also use the same technology; Albert Biermann revealed that the advantage of dual inverter technology is that through the architecture of the existing model, there is no need to modify too many hard equipment, of course, the integration of software and power control technology to a considerable level, but in summary, within the existing body space, to achieve a significant increase in performance. Albert Biermann further said that Mercedes-Benz's EQS also has a similar application of dual inverter technology, which Mercedes-Benz calls "Six-Phase Engine".
An optional E-GMP platform with variable damping chassis is available
Kia EV6 GT is built on the Group's E-GMP electric vehicle platform, in order to meet the handling needs and overall balance of the E-GMP high-performance version of the car, EV6 GT provides an optional variable damper chassis (Adjustable dampers) equipped, according to the current test prototype, equipped with Normal, Eco, Sport, GT a total of 4 modes, after switching can provide different road reaction effects, Take into account the needs of general daily use and extreme state.
According to the experience of European media, in Normal and Eco mode, its chassis reaction is like a general passenger car, mainly based on comfort, although with 21 inches of bead conditions, it will feel a little tire noise, but overall there is no problem with daily use.
Switching to Sport and GT modes (the buttons are located on the steering wheel), you can immediately feel the suspension harden, the road sense feedback is more direct, and the driving feeling with the 21-inch bead is more sporty, and the difference can be said to be quite obvious.
Previously, Hyundai revealed to the media that the Ioniq 5 N may not be far from the EV6 GT due to the use of the group's E-GMP platform, but the Ioniq 5 N will have a big upgrade for the handling of the vehicle, especially the chassis setting.
