Recently, Genesis GV60 electric The car is launched in China, with a starting price of 285,800. As a luxury brand under the Hyundai-Kia Group, Genesis was first developed for the North American market. It referred to Toyota's development process of establishing the Lexus brand and established a foothold in North America with its low price and high configuration. GV60 The starting price in North America is US$60,400, which is 2,000 US dollars more expensive than the larger Cadillac Ruige. The domestic price of the Ruige starts at US$440,000, while the Hyundai GV60 is only US$280,000. This is a "conscientious" price in order to increase the influence of the new brand. , or reduce allocation and then enter the country? Let’s analyze it in detail below.
What are the motors and chassis of Korean luxury cars like?
GV60, like the popular Kia EV6 overseas, is based on the Hyundai Kia E-GMP electric modular platform. The motor includes three configurations - single motor, dual motor, and dual motor high-performance version. The motor adopts Three-in-one design, consisting of motor, single reduction gear transmission and inverter. The three components are integrated into a compact module. Each motor also contains a custom rotor and ball bearings, and is capable of spinning at a high speed of 19,000 rpm, which is 70% higher than the previous generation of Hyundai motors. . Hairpin winding technology increases motor efficiency by 20% compared to the old model.
For reference, the motor speed of common electric vehicles is around 15,000 rpm, and Tesla’s is 18,000 rpm. Modern motor technology is not inferior to any competitors. The speed of the motor has a similar effect to the speed of the internal combustion engine. The higher the limit speed, the stronger the power output under the same volume, and can bring about a super power mode.
Take the dual-motor version of GV60 as an example. By pressing the Boost button on the steering wheel and pressing the super power mode, a higher speed can immediately bring an additional 20kw power. The motor power increases from 160kw to 180kw. The function can immediately release an additional 40 kilowatts of power, and the maximum power soars from 435 horsepower to 490 horsepower. In order to make the motor more durable, the super power mode is set to last for 10 seconds, but it is enough time for starting acceleration or high-speed overtaking. In Boost mode, the acceleration time to 100 kilometers is only 3.9 seconds.
So can Korean chassis design keep up with traditional luxury brands? The E-GMP platform brings farming possibilities to this car. E-GMP extensively uses aluminum alloy materials. Compared with the steel design, the entire vehicle is 40kg lighter. Hot stamping is used in key areas such as the A and B pillars and floor beams. parts, which are thermoformed and quenched to provide high strength. Aluminum die-cast components are used at the front and rear of the vehicle, including the suspension towers. The door sills and rear bulkhead are made of extruded aluminum, while the front seat beams are made of carbon fiber CFRP. The use of materials is not inferior to other luxury brands.
The 76.4-degree ternary lithium battery is installed at a lower position to lower the center of gravity of the vehicle. The structure supporting the battery adopts a specially designed energy load path, which can reduce the risk of the battery in a collision.
GV60 dual-motor four-wheel drive luxury version (302,800) configuration comparison in North America
First Driving
It should be noted that although the GV60 provides rear-wheel drive globally version, but currently only the dual-motor four-wheel drive version is available in North America. That is to say, you cannot buy the domestic single-motor version priced at 285,800 yuan. Therefore, you need to compare the dual-motor version with a starting price of 302,800 yuan. The dual-motor power is exactly the same, and the front is Small motor, the rear is the same 160kw motor as the high-performance version, but without Boost mode, the acceleration time to 100 kilometers is the same as in North America, 5.5 seconds.
In terms of suspension, the GV60 adopts a MacPherson strut front and five-link design at the rear. It improves controllability through a reinforced subframe and a four-point installation of the motor. The suspension components and subframe are hydraulically mounted. bushings to reduce noise. The overall tuning of the GV60 is more sporty, and the handling is more flexible than ordinary SUVs.
Second Ride
Although the 4.515-meter body is only the standard for compact SUVs, the 2.9-meter wheelbase allows ample space in the second row. The disadvantage is that the trunk is small. It is only 432L, which is similar to the volume of the A-class sedan. As an imported car, the size of the GV60 is the same as overseas, with no change.
But in terms of configuration, the North American entry-level dual-motor version has richer configurations. The domestic four-wheel drive entry-level model lacks a heated steering wheel, seat ventilation, main driving position, active noise reduction, and leather seats. , driver's leg rest adjustment, passenger's lumbar support adjustment, 17-speaker Bang & Olufsen audio.
The entry-level version in North America is similar to the domestic four-wheel drive flagship version, but the price of the flagship version reaches 351,800 yuan. If you add the 5,000 yuan optional 20-inch wheels (standard in North America), the final price is actually the same as North America is very close, and the price difference is not as huge as everyone thinks.
Third charging/battery life
One of the great advantages of GV60 is its charging capability. Its compatible 800V charging and 400V charging architecture makes the vehicle fast charging time very short,
< p> This is Hyundai Group’s patented technology that automatically manages the motor and inverter. At a supercharging station, if a 350kw charger is used to charge, 80% can be charged in 18 minutes. The electric GV70's battery can be recharged from 10% to 80% in 18 minutes when charged with a 240kW 350kW charger.The imported domestic battery is slightly smaller than the North American one, changed from 77.4 degrees to 76.4 degrees. In terms of battery life, the four-wheel drive luxury version of CLTC has a battery life of 618 kilometers, and the four-wheel drive high-performance version has a battery life of 551 kilometers. The real battery life can be Referring to the North American "Carand Driver" test, the high-performance version has a total range of 321 kilometers when cruising at a high speed of 120km/h, and the ultra-high-speed range is maintained at 58%. This kind of endurance is worthy of recognition.
Car selection detective’s opinion: The GV60’s motor, battery and battery life all meet high standards and are not inferior to any competitors. In terms of configuration, the 280,000-class rear-wheel drive version is sufficient, but I want the North American version. For standard configuration, you must choose the four-wheel drive flagship version. As a "small car" only 4.5 meters in size, the price is slightly higher. For the domestic market that likes large-space models, the GV60 is destined to be a niche choice. What do you think of modern luxury brand electric cars? Discussions welcome.
