This strange tank history was born in the 1960s, when the Swedish army planned to develop a new line of main battle tanks to deal with the Soviet Union. Swedish engineers propose a unique idea when not to use turrets like conventional tanks. The main gun was fixed to the body of the vehicle, but did not have a rotating turret like normal tanks. The engineers argued that the cannon fixed to the hull made it more accurate to fire than the rotating turret. In addition, the use of a turret makes the overall height of the tank significantly reduced, harder to detect on the battlefield, and the low height also makes it harder for the tank to hit the enemy’s fire. Eventually a design was born, called Stridsvagn 103. Sweden wants to develop the Stridsvagn 103 into a high-speed assault and ambush armor vehicle, taking advantage of the superiority of precision firing to destroy, disrupting the enemy tanker formation. The Stridsvagn 103 is fitted with a 105 mm main gun, with an automatic reload system. Because there is no turret, the angle of lift and lowering of the gun is adjusted through a special suspension that can be lifted and lowered when necessary. However, the angle of elevation and lowering of the cannon is quite limited, Stridsvagn 103 cannot shoot from above. The crew must rotate the entire body to adjust the line of sight. Stridsvagn 103 tanks were produced to full scale from 1967 and lasted until 1971. In total, about 290 vehicles were produced and handed over to the Swedish army. In the 60s and 70s, Stridsvagn 103 was the core of the armored Swedish force. The car chain has small hooks to increase the grip of the road. The chassis has a blade that can be used to dig a camouflage tunnel for the vehicle. The Stridsvagn 103 tank can wade in about 20 minutes after the preparation time, the wading speed is about 6 km / h. In 1967, Norway compared this tank with the Leopard-1. When the lid is closed, the Stridsvagn 103 detects the target faster than the Leopard-1, the opposite result when opening the door. In 1975, two Stridsvagn 103 were shipped to the US for performance testing with the M60A1E3 version. The results showed that Stridsvagn 103 fired more accurately, but the average time per shot was 0.5 seconds slower. Stridsvagn 103’s superiority in accuracy was not enough to compensate for design flaws. This bizarre tank was quickly replaced by the Stridsvagn 122 (version of the Leopard-2) German made in Sweden in 1997.

Smartphone maker Huawei launches the first car model Huawei is best known for making smartphones, but the Chinese tech giant is planning to invest $ 1 billion in research into electric vehicle technology and self-driving cars. As part of that plan, at the ongoing Shanghai Auto Show, Huawei officially introduced its first self-made model, the Huawei Seres SF5. The SF5 stands out with its elongated headlamp, reverse claw, LED daytime running lights and a mesh grille with body color. Hidden door handles in the bodywork with a rounded overall style. Inside the interior compartment, the SF5 is equipped with a digital clock, two-spoke steering wheel, next to a dial selector. The materials used to decorate the cabin include wood and metal. Mood lighting, sunroof, heated front seats, cooling and massage mode are all other options on the car. Huawei can connect to smartphones and automatically deliver music and positioning information between the two sides. Also equipped with voice control technology and audio system with 11 speakers. Engineers also focused on noise and vibration reduction, demonstrated through the addition of double-layered front glass and a variety of damping materials. The interior noise is only 38 dB in idling mode, according to the company. SF5 is also equipped with mm-frequency radar, ultrasonic sensors, a series of cameras, adaptive cruise control, traffic congestion assistance, automatic emergency braking, lane keeping assist and collision warning. front. The 1.5-liter, 4-cylinder engine acts as a generator. The vehicle is equipped with a battery pack that powers two electric motors with a capacity of 543 hp and 820 Nm of torque. SF5 is capable of accelerating from 0-100 km / h in 4.7 seconds. In pure electric mode, the car can run 180 km and with the help of a gas generator, the mileage is more than 1,000 km. Seres SF5 is currently on display at the Shanghai auto show and will be available in Huawei showrooms soon. Expected selling price is 33,356 USD (about 770 million VND) and delivery may start in May.

Huawei is a brand that produces smartphones worldwide famous. However, it seems that Huawei not only wants to stop at smartphone production, but also encroach on the automotive segment. Participating in the 2021 Shanghai Motor Show, the first Huawe electric car was officially unveiled. Called by its full name Seres Huawei Smart Selection SF5 2021, this car carries a crossover style. This is a model created by Huawei, along with partner Seres based in California, USA. In terms of size, Huawei SF5 has a length of 4,700 mm, width of 1,930 mm, a height of 1,625 mm and a wheelbase of 2,875 mm. With this size, the Huawei SF5 is listed in the midsize crossover segment, similar to the Hyundai SantaFe and the Kia Sorento. Outside, the SF5 has a design that is almost unchanged from the concept car of the same name that the Seres brand introduced in 2019. The car is equipped with slim headlights, clawed back. Meanwhile, the L-shaped daytime positioning LED strip embraces the headlight cluster. Right below is the front fog lamp with a boomerang-shaped design and embraces the 2 air slots on the front bumper. In the center position of the front of the car is the grille with a mesh of canopy. Similar to many new models today, the electric Huawei SF5 also comes with a door handle that sinks into the body and can be turned on when needed. Meanwhile, the car’s window glass is designed as soft wings. Next is the slope to the back and the alloy rim with a 5-spoke design, 2 color combinations. Behind, the first Huawei car comes with LED taillights connected by a strip of lights in the middle, the roof spoiler with integrated overhead brake lights and a fake wind diffuser under the rear bumper. Inside the Huawei SF5 is the interior space designed in a minimalist style, clearly shown through the dashboard. Here, we will see the air-conditioning vents stretching across the width of the dashboard, interrupted by the large touchscreen display as well as the digital instrument panel. This central screen connects to a HiCar system based on Huawei’s Harmony OS. With this system, users can connect their smartphones to the vehicle, synchronize and control smart devices through the touch screen. Below the infotainment screen there is no center console cluster, but a storage compartment with a cover. Meanwhile, the car’s gear knob is located right in front of the center armrest. Adding to that is the 11-speaker Huawei Sound sound system, which promises to bring a theater-like experience to the occupants of the car. This system works to prevent unwanted outside sounds from entering the car and combines with the double-layer soundproof glass as well as a damping system to provide a quiet interior for the Huawei SF5. The power supply for the Huawei SF5 is 1 electric motor or 2 electric motors, depending on the version. Meanwhile, the 4-cylinder petrol engine, turbocharged, 1.5L capacity only plays a role to charge the battery, increasing the range of operation for the car. In version 2 electric motor, 4-wheel drive full time, this crossover model owns a maximum capacity of 543 horsepower and a maximum torque of 820 Nm. As a result, the car can accelerate from 0-100 km / h in nearly 4.7 seconds, run 180 km with an electric motor and add 1,000 km if the gasoline engine is involved. When needed, the battery of Huawei SF5 can be used to charge electrical equipment such as TVs. Not only fast and powerful, Huawei SF5 also has modern safety equipment such as driver assistance in traffic jam, adaptive cruise control, forward collision warning, automatic emergency braking and vehicle entry. in the middle of the lane.

Porsche cars are perfected on a new technological line Painting the body of a new Taycan on an assembly line at the Zuffenhausen factory previously required workers to move a tool weighing almost 7 with just the thumb 3,600 times per work day. It sounds strenuous, but Porsche has adopted a new system that eliminates that stress and improves quality by using patches to seal holes in the bodywork. These holes are not visible to the naked eye, but are intended to be filled by anticorrosive paints while in the paint shop. Once completed, these holes must be sealed so that they are watertight. If not, leaks will form. Taycan was not only the first Porsche to use this new patching method, but also the first car in the world to do so. The holes in the body of Taycan will be painted with new technology A total of 106 of the 143 holes in the Taycan body are now patch sealed in a very quick and automatic process. As noted previously, line workers do not have to push up to 3,600 plugs into holes in the body per shift. This new process is less complicated, faster and produces a higher quality product. The robot does this kind of work that looks like a barcode scanner. It only takes three minutes to do the whole job while 1 person needs more than seven minutes. Dirk Paffe, Paint Shop Process Planning Manager at Porsche: “The key feature of the solution is not just the seal itself, but also the automation of the process. We can glue patches in large quantities and at high cost, speed with absolute precision using a robot. ” New technology on Porsche Taycan will be spread on its models in the near future Does this mean that robots will soon take over all the work on the human assembly line at Porsche? Not at all, but making the worker’s life much easier and securing a better quality car.
