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

The Soviet Union spent 22 years drilling into the Earth’s crust and reached a depth of 12,262 meters — they found water where it was thought impossible, hydrogen bubbling from the rock, granite that is 2.7 billion years old, and temperatures of 180 degrees that melted the drill bits.

Gaddafi built the world’s largest artificial river under the Sahara — it’s 4,000 km of giant pipes that pump 40,000-year-old fossil water to entire cities in Libya.

Discovery in Africa scares even scientists: a study published on April 23 reveals that the crust in Turkana has become so thin that it could pave the way for the continent’s division and the emergence of an ocean in the future, in a gigantic geological transformation.

A German architect built a cylindrical house in 1994 that rotates to follow the sun throughout the day, generates 5 times more energy than it consumes, and was the world’s first energy-positive house.

A company that drilled for oil has drilled 4.8 kilometers of rock in Utah and found a never-ending heat of 290 degrees — now it is building the world’s first next-generation commercial geothermal power plant, with 100 MW connected to the grid in June 2026.

Brazil spent R$ 1.9 billion on a giant bridge to Paraguay, and it is already finished, but no one can use it properly because the access points are not ready, and traffic remains blocked months later.

Congress is evaluating at least 15 projects that could further increase electricity bills, expand subsidies already paid for by consumers via CDE, exceeding R$ 50 billion per year, and create new tariff pressures in the middle of an election year.

The Federal Revenue tightens the net against habitual debtors with debts over R$ 15 million and more than R$ 25 billion in accumulated liabilities, and begins to notify taxpayers with assets below the declared liabilities.

A study on the Amazonian Craton raises a geological alert in Brazil: the oldest rocky core of South America may hide signs of deep instability beneath the planet’s largest river basin, challenging models about the resistance of ancient continental platforms.

Foreign investment in telecom in Brazil rises to R$ 2.9 million in March, advances 8% over 2025, bringing the quarter to R$ 8.4 million and reinforcing international investment in 5G expansion, internet in remote areas, and the country’s digital modernization.

In Madrid, the Torres Colón defied engineering logic with 116 meters, 23 floors above ground, and top-down construction, in a project suspended by prestressed concrete and cables that transformed two inverted towers into an architectural icon.
