Volvo Launches Unprecedented Engine With Start-Stop System In Heavy Trucks, Reducing Fuel, CO2, And Bringing Advanced Safety Features On The Roads.

Volvo Trucks announced an unprecedented innovation in the heavy transport sector. The Swedish company revealed the world’s first truck engine with start-stop technology. The feature aims to reduce fuel consumption and CO2 emissions, reinforcing the manufacturer’s decarbonization strategy.

How The Technology Works

The system is based on the already known I-See and I-Roll technologies. The engine is temporarily shut off during descents, resuming operation smoothly and automatically, without driver intervention. Additionally, the technology analyzes the topography and road conditions to identify the best moment to act.

The new generation of these technologies activates at speeds above 60 km/h. Thus, the engine operates more efficiently, leveraging the kinetic energy of the truck and reducing waste.

Integration Details

According to Volvo, I-See predicts when an ascent is approaching and adjusts speed before the incline. During the climb, the system uses stored information to avoid unnecessary gear shifts, ensuring a smoother transition.

Before an elevation, I-See activates Eco-Roll, which disengages the transmission and allows the truck to roll freely. This saves energy and decreases brake usage. At the end of the descent, the system applies the engine brake at the ideal moment or maintains momentum, depending on the road.

The system also takes into account curves, roundabouts, and even traffic ahead. To do this, it utilizes high-resolution maps that allow for calculating the best driving strategy. When cruise control is activated, I-See manages gears, acceleration, braking, and free-rolling, forming part of the I-Save package.

Company Statements

Jan Hjelmgren, Head of Product Management at Volvo Trucks, emphasized the importance of innovation. “Our engineers have done it again – innovating with a new engine technology that helps make truck transportation more fuel-efficient,” he stated.

He reinforced that the measure integrates the company’s decarbonization strategy. “We will continue to innovate to make our combustion engines even better and reduce our environmental impact,” he added.

Market Availability

The new feature will be offered in the Volvo FH and FH Aero models, both equipped with a 13-liter diesel engine. The company confirmed that customers will be able to order the new feature starting in September 2025.

In addition to this innovation, Volvo recently launched an updated dynamic steering system aimed at increasing driver safety. The new Volvo Dynamic Steering can detect a front tire blowout and automatically mitigate the impact in fractions of a second. This helps the driver maintain vehicle stability even in critical situations.

Safety On The Roads

According to the manufacturer, the system reduces lateral forces caused by a sudden loss of air pressure. Thus, it avoids risks of loss of control in the event of a flat tire.

Combining energy efficiency and safety, Volvo reinforces its leadership position in heavy transport technology. The strategy remains aligned with the pursuit of sustainable and safer solutions on the roads of the future.

Safety On The Roads

A giant printer called the “Ferrari” of concrete has landed in Latin America and can already build a 120-square-meter house in just 48 hours, making the traditional construction site look like something from the last century.

A British company has installed in the middle of the ocean the world’s first floating platform that generates electricity 24 hours a day from the temperature difference between the surface and the depths of the Atlantic, without relying on wind or sun.

Great Atlantic Sargassum Belt has ceased to be a climatic phenomenon and has become a biological system that feeds on itself, with 8,000 kilometers in length, 37 million tons of algae, and scientists confirm that it is now permanent.

China is building an artificial island in the middle of the sea, covering 20 km², to construct the largest offshore airport in the world, the Dalian Jinzhouwan. This $4.3 billion project is anchored on more than 3,000 pillars embedded in the rock beneath the ocean and is scheduled to open in 2035.

A robot named Walter does the work of five bricklayers per hour and can save the construction industry, where the average age of professionals is 46 years and almost no one wants to learn the trade anymore, in the United Kingdom.

Engineers had to pour concrete mixed with tons of ice throughout entire nights in the Dubai desert to erect the Burj Khalifa; any carelessness could clog the pipes half a mile high.

The James Webb telescope spotted a planet 700 light-years from Earth with mornings full of sand clouds and nights with clear skies, the temperature difference between the two hemispheres reaches an impressive 170 degrees.

On the other side of the planet, a Brazilian doctor operates on a patient in Porto Alegre while being in China, almost 19,000 km away, using a surgical robot that responds in 200 milliseconds in a procedure that seems like science fiction.

China outpaces Elon Musk with Unitree humanoid robot available on AliExpress for $6,800, with free shipping and international delivery, turning billionaire technology into something anyone can buy online.

Lula says that the Brazilian naval industry will “thrash” China and Korea, while the government announces billions for barges, pushers, and a new hydro terminal in the Amazon.

Far from football, São Paulo idol and former national team player becomes a wine producer in Italy, transforms the nickname “Prophet” into his own brand, and now runs a winery, restaurant, and hotel in Piedmont.

Train of up to 111 tons leaves China for Brazil, crosses almost 20,000 km in up to 70 days by ship, and arrives in São Paulo in such a tight operation that a truck even had to deflate its tires to pass under a viaduct.
