Volvo Car Group already testing its new three-cylinder engine
- New 3-cylinder engine developed by Volvo Cars in Sweden
- Volvo’s next step in its impressive Drive-E powertrain program
- Broad range of performance levels up to around 180 hp
Volvo Cars today confirms its production program to develop a lightweight 3-cylinder petrol engine. The engine, wholly developed in Sweden, will join the class-leading 4-cylinder Drive-E engines in displaying Volvo’s engineering prowess and commitment to efficient power.
“We have come a long way in the last few years at Volvo. Investments from our parent company, Zhejiang Geely Holding Group, have enabled us to recapture our position as a leader in the field of powertrain engineering. The development program for the new 3-cylinder engine is very advanced and we have already begun prototype testing of the unit,” says Dr. Peter Mertens, Senior Vice President Research & Development at Volvo Car Group.
Volvo has a long history of developing its own unique 6, 5 and 4-cylinder engines and in-house expertise. The move to include a 3-cylinder in Volvo’s engine program is a natural next step in Volvo’s strategy of downsizing. The application of class-leading technology and analysis techniques enables more power and better fuel economy from smaller displacement internal combustion engines than ever before.
“We have learned a lot from the development of our 4-cylinder Drive-E engines and translated this into a highly responsive, compact and powerful premium-quality 3-cylinder engine. The engine is being developed primarily with our new CMA architecture in mind but will also provide power for our 60 Series cars thanks to Volvo’s advanced turbo technologies, while also meeting Euro 7 emission targets,” says Michael Fleiss, Vice President Powertrain at Volvo Car Group.
Built with a keen eye on the future, the new Drive-E 3-cylinder engine is designed to support several different applications, in-line with the growing demand for a real-world blend of performance and efficiency.
“The beauty of the new 3-cylinder engine we are developing is that it can be built on the same production lines as our 4-cylinder engine, offering flexible production potential which can be adapted to suit business needs as we grow. This marks an important step forward for Volvo Cars. In terms of our power and efficiency, Volvo’s engineering excellence will shine through with the Drive-E 3-cylinder engine,” concludes Dr. Mertens.
Team Vestas Wind looks at new boat option
ABU DHABI, December 8 - Team Vestas Wind is ‘exploring the opportunity’ of re-entering the Volvo Ocean Race with a new boat just over a week after their Volvo Ocean 65 ran into a reef in the Indian Ocean..
With their crew now safely on land, attention has turned to retrieving the stricken vessel, grounded on the Cargados Carajos Shoals (St Brandon), some 260 miles north east of Mauritius - and whether the Danish team will return to the race.
“It is Vestas’ clear ambition to get Team Vestas Wind out sailing again,” said the sailing team’s CEO Morten Albæk, at a press call in Abu Dhabi. “We’ll do everything within our means to make that happen.
“That said, the assessment from all parties is that the boat can’t be repaired, and therefore one of the options we’re looking into is building a new boat,” added Albæk, who is also title sponsors Vestas’ Chief Marketing Officer.
“Whether that can be done, and done in a time which is meaningful for Team Vestas Wind to re-enter the race, is still to be concluded.
“We’re working closely together with Volvo Ocean Race on exploring that opportunity.”
Skipper Chris Nicholson (AUS), who led his crew in an early hours evacuation from the boat on November 29, and on to the remote island of Íle du Sud, where they remained for the next 48 hours before hitching a ride to Mauritius on a local fishing boat, echoed those hopes.
“Prior to the crash in the preceding 48 hours, Wouter and I in regard to our normal duties of looking where the boat was going with the routing, noticed that there would be some seamounts. When I saw those I asked what the depths and the currents and the wave conditions would be.
“Wouter’s reply was that the depths went from 3000m to 40m, (which) were the extremes of the depths, the current was negligible and we would monitor the wave state as we approached...”
Team Vestas Wind navigator Wouter Verbraak (NED) explained the reason for the accident to the media:
“In hindsight we would’ve continued to zoom in on the area much more, on the electronic charts. Not doing so is the big mistake that I made, but the good thing is that we didn’t make any more.”
The incident happened around the midway point of the 5,200 nautical mile Leg 2 from Cape Town to Abu Dhabi of the nine-month round-the-world race which finishes in Gothenburg, Sweden, on June 27 next year.
It is Australian Nicholson’s fifth Volvo Ocean Race, and he and the rest of the crew have been debriefed by team and race officials over the weekend in Abu Dhabi and will shortly return home to their individual countries.
Volvo Ocean Race CEO Knut Frostad explained that, for the damaged boat, the recovery operation is still ongoing, and the parties involved are working together to bring about a swift resolution.
“We’re all making our absolute best efforts to do what is right. We have a very clear mission on this and that is to make sure that the absolute minimum impact is done to the environment.
“The plan is to remove the boat, either in its current form, or in a different form. We’re working on this right now, trying to make it happen as quickly as possible.
“Our next objective is to learn from this, and support Vestas, Powerhouse, and the team in their efforts to have a future in the race.
“I must underline that that is no small challenge. I don’t want anyone to have expectations that this will easily happen; it’s an enormous challenge.
“But the Volvo Ocean Race is all about enormous challenges - and here is another one.”
Patrick Lammers, a member of retail board RWE, said on behalf of sub-sponsors Powerhouse: “We are seeking opportunities to return to the race as soon as possible. In what form, and when, is impossible to say at this time, but all options are seriously considered.”

Volvo Cars introduces Twin Engine technology in world’s most powerful and cleanest SUV
Volvo Cars introduces Twin Engine technology in world’s most powerful and cleanest SUV
The first Volvo designed from the ground up for plug-in/electrification compatibility, the XC90 T8 delivers all the performance of a luxury SUV, but with emission levels that even small hybrid cars struggle to match.
When designing the XC90 T8, Volvo Cars chose not to compromise on performance, driving pleasure, efficiency or even luggage space. By building on the new modular Scalable Product Architecture (SPA) platform and successful Drive-E petrol powertrain, the company has created a uniquely roomy 7-seater SUV that delivers 400hp/640Nm combined with ultra-low emissions (59g/km) and high fuel efficiency (2.5 l/100km). The fuel economy according to the U.S. driving cycle is 59 MPGe.
“The XC90 T8 is a plug-in electric car, hybrid car and high-performance car rolled into one,” says Dr Peter Mertens, Senior Vice President Research and Development of Volvo Car Group. “The Drive-E engines already offer highly competitive performance versus the competition. The T8 takes it further into a leading position.”
A driving mode for every need
The XC90 T8 can go from 0 to 100km/h (62 mph) in 5.9 seconds, delivering all the driving pleasure customers have come to expect from a Volvo SUV. But driving pleasure is only a fraction of what the XC90 T8 offers: the car has five different driving modes that deliver a range of performance and efficiency-enhancing characteristics. Using either a scroll wheel on the center console or a touchscreen on the dashboard, drivers can choose from:
Hybrid: This is the default mode, suitable for everyday use. Here, the vehicle will automatically alternate between drawing power from the 2-liter, 4-cylinder Drive-E engine and the electric motor to deliver the best overall fuel consumption.
Pure electric: In this mode, when the high-voltage battery is fully charged, it serves as the car’s sole energy source, powering the electric motor over the rear axle. The XC90 T8 has a range of more than 40km using just electricity, which covers the total distance most people drive in one day. And thanks to the regenerative braking system, this mode is super-efficient in the stop-and-go traffic of city environments. If more power is needed, the Drive-E combustion engine starts up automatically.
Power mode: Here, drivers get the combined performance of the combustion engine and the electric motor. On start-up, the SUV takes advantage of the electric motor’s superior response and instant torque curve, while the combustion engine gets up to speed. This combination offers better torque at lower revs, equivalent to that of a large displacement engine like the V8.
AWD: This mode offers constant all-wheel drive on demand. The advantage of being able to select AWD manually is that the driver can use it when needed, or choose to save energy for later.
Save: If the battery is charged, this mode allows the driver to “freeze” the battery level and save it for later use with Pure Electric drive. On the other hand, if the battery is low, the driver can use the combustion engine to charge the battery to a certain level for later use with Pure Electric drive.
Under the shell
Many of the XC90 T8’s powertrain features have been optimized specifically for hybrid technology. Here are the main components of the system:
A specially modified version of the 4-cylinder Drive-E gasoline engine is under the hood. Already known for its ability to more efficiently deliver the power of an engine twice its size, the Drive-E engine is enhanced in the XC90 T8 by a supercharger and a turbocharger for a total power output of 318hp and 400Nm torque.
The 8-speed automatic gearbox has also been specially adapted for the hybrid: shift-by-wire technology allows drivers to control the transmission electrically (a luxurious touch is the gearshift as made of handmade Swedish crystal). A larger oil pump provides the necessary lubrication during electric drive and enables quicker pressure build-up when seamlessly going from electric to combustion drive.
The crankshaft-mounted starter generator (CISG), located between the engine and the gearbox, performs three important functions: it is a powerful, 34kW starter motor that allows the car to go from pure electric drive to combination combustion drive seamlessly, so drivers can experience the car’s petrol engine and electric motor as one unit; it is also a powerful electric generator; and finally, it acts as an electric engine booster, working with the supercharger and turbocharger when extra power is needed, providing up to 150 Nm of extra torque.
The high-voltage (270–400V) battery, delivering 65kW of power, is an excellent example of Volvo’s success with the XC90 T8. While other carmakers have struggled to combine the bulk of a battery pack with a luxurious and spacious interior, Volvo has managed to overcome this challenge by placing the battery centrally in the tunnel of the car. There are several advantages to this position. For example, the battery does not impact the amount of available space inside the car. This means that there is room for three rows of seats – plenty of space for people and luggage. Furthermore, the battery placement gives the SUV a low and central center of gravity, making the XC90 T8 easier to handle and safer to drive.
Rear electric motor
Delivering 82hp (60kW) and 240Nm torque, the large electric motor sits on the rear axle and drives the back wheels in electric and power-boost modes. The rear placement is significant because it allows for a larger motor, which is useful for following stop-and-go city traffic rhythms. This placement also makes efficient all-wheel drive possible because each axle has its own power source.
Two-step braking system
The XC90 T8 blended braking system partly uses brake-by-wire technology to recover and transmit energy back into the car, either to recharge the battery or for immediate use. The system is also equipped with a unique stability function that controls the amount of energy that may be safely regenerated.
Unique cooling and climate system
The unique cooling system is composed of two extra circuits. The first cools the CISG and the large electric motor on the rear axle, while the second cools the battery in one of two ways: either passively, via the radiator, or actively through integration with the car’s climate system.
For convenience and efficiency, drivers can pre-condition the XC90 T8’s drivetrain, battery and cabin, either directly from within the car or by using the Volvo On Call mobile app. This ensures that, whether it’s freezing or hot and humid outside, the car will be heated or cooled as necessary and ready to go by the time the driver enters. Pre-conditioning can be done while the car is plugged in, which is beneficial from a CO2 perspective since it ensures that the battery will last as long as possible in Pure Electric Drive mode.
A heritage of innovation
As the world’s most powerful and cleanest SUV, the XC90 T8 joins a long list of Volvo Cars innovations designed to create a more comfortable driving experience, a cleaner environment and safer roads.
