Volvo XC90 Coasting Transmission Deep Dive | How, when and why of coasting

In our recent 2021 Volvo XC90 Recharge review, its turbocharged-supercharged-hybridized powertrain delivered impressive horsepower and fuel economy. But Volvo has one additional trick up its sleeve, propelling a car with power that's simpler, cheaper and all-natural: It's the power of momentum and gravity. I've always been halfway to a hypermiler. I'm not obsessive about it, but in city driving, I enjoy timing stoplight approaches to keep the wheels rolling and avoid the inertia of restarting from a stop. There's little point to needlessly racing and braking between red lights, wasting kinetic energy (and therefore fuel). So I tend to drive strategically instead, often catching up with the drivers who jackrabbit but get hung up at the lights. And, back when I owned a long line of vehicles with manual transmissions, I coasted. Coasting used to be slightly controversial. Some claimed it doesn't actually save gas, though my mileage calculations showed otherwise. Another school of thought insisted that removing engine braking from the equation, even momentarily, constitutes a dangerous loss of control. Of course, an experienced driver can slip a manual transmission back into gear in a flash when engine braking's actually needed. And one should always use some common sense and judgment about when and where to coast. I'm not talking about careening down a 15% grade into a school zone.  Anyway, those arguments became moot when automatic transmissions pretty much took over. (And no, never coast with a typical automatic transmission. Even if it weren't damaging to your type of automatic — but assume that it is — the risk of screwing up a nudge of the shifter from drive into neutral is too great.)

Volvo calls the feature on its Aisin eight-speed "Eco Coast." Some Mercedes, BMWs and others call it "sailing" or "gliding." The Hyundai Ioniq, Ford Mustang Mach-E and Polestar 2 are among EVs that allow you to cancel out all regeneration and freewheel downhill. And future cars such as the BMW iX are also being designed to do it. By building coasting into the clockworks, automakers have taken any traffic safety concerns out of the question, because the car will instantly switch you back into gear when needed.

Volvo teases minimalist, no-button EX90 interior

The march to the November 9 reveal of the Volvo EX90 takes its next step with these renderings of a pared down interior. We'll see soon how it looks once the new materials, textures, colors, and tunnel console are added, but for the moment, there are four elements: An instrument panel with a demure HVAC vent, broken up by a steering wheel, a small, uncovered screen behind the wheel, and an infotainment screen. The portrait-oriented tablet carries over from current Volvo design, so too a three-spoke wheel. Everything else in Volvo's current interior schemes is thrown out, including the knobs and buttons on the center console. It looks like the premium brand's version of the interior we were introduced to in the Polestar 3. Fitting, since both vehicles will ride on the same platform and be built at the same U.S. plant.  The cabin's physical design and the car's technology share a same philosophy, which is, "What you need, when you need it." Volvo says that the sensor suite around the EX90 will give the car a 360-view of what's happening outside and inside the car. " Thomas Stovicek, head of UX at Volvo Cars, said, "Since the car also understands its surroundings and you better than ever before, we can create an even safer situation by reducing mode confusion, distraction and information overload." On the infotainment side, we're told this will be done by the vehicle providing contextual options and menus on the two screens. The center screen, which looks larger than the current XC90 unit, performs the roles we've come to expect of it. Autocar spoke with automaker developers and said the screen "will also show information based on context. If you’re simply driving along, a bar near the bottom of the screen will show media information; if youÂ’re on a call, it will show other controls; if itÂ’s cold, it may show the defrost button, etc." This situational knowledge will be especially important as more roads are opened up to hands-free driving and as self-driving capabilities become more capable. Swedish engineers point to the handover from hands-free and autonomous driving back to hands-on driving as a crucial moment. It wants to make that handoff "effortless and intuitive." The display behind the steering wheel is where the driver will go first for traditional info like speed and range, also to understand the operational state of the driver aids.

AB Volvo to build trucks using steel forged without fossil fuel

STOCKHOLM — Swedish truck maker AB Volvo and steel maker SSAB have signed an agreement to produce the world's first vehicles made of fossil-free steel, the companies said on Thursday. Volvo plans to start production this year of prototype vehicles and components from steel made by SSAB using hydrogen produced from renewable energy. Small-scale serial production will start in 2022. "This is an important step on the road to completely climate-neutral transport," Volvo CEO Martin Lundstedt said. The vehicles and machines will be emissions-free in operation, Volvo said, without specifying how they would run, while adding the company is reviewing all the materials used in their construction to eliminate anything based on fossil fuels. It will be sourcing steel from green steel venture HYBRIT — which is owned by SSAB, Swedish state-owned utility Vattenfall and Swedish miner LKAB. Last August, it began test operations in Lulea, Sweden, to replace coking coal, traditionally needed for ore-based steel making, with fossil-free electricity and hydrogen, which in turn is produced using only renewable power.
