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 begins rolling out over-the-air software updates in the U.S.

Volvo announced that two of its models are now compatible with over-the-air software updates. The electric XC40 Recharge and three versions of the XC60 are eligible to receive a variety of wireless changes including driving range improvements and small bug fixes. The Swedish firm published details about its over-the-air software updating system shortly after going public. It's compatible with the new Android-based infotainment system found in many of its cars, including the C40 Recharge unveiled in 2021, and it works a lot like the similar technology that your smartphone features in the sense that the software updates itself; there's no need to stop by a dealer or plug in a USB drive. When an update is ready, a message appears on the dashboard-mounted touchscreen asking motorists if they want to download it. Owners of compatible cars in the United States received their first over-the-air software update last week. Labeled version 1.7, it notably added SiriusXM satellite radio compatibility. Volvo also noted that the XC40 Recharge received additional driving range during the update. Looking ahead, Volvo plans to wirelessly add new features and enhancements to the infotainment system. Only some 2021 and 2022 models can receive over-the-air updates. As of writing, the list of compatible cars is limited to the aforementioned XC40 Recharge, the XC60, the XC60 Recharge, and the XC60 Polestar Engineered. It's reasonable to assume that the feature will spread across the range in the coming years as new models are launched. Sister company Polestar also offers over-the-air updates on the 2.

Volvo Recharge models get more power and electric range

Volvo Belgium announced a few big improvements for plug-in hybrid models on the automaker's Scalable Product Architecture, meaning the 60 and 90 series Recharge models — S60, V60, XC60, S90, V90 and XC90. First, the battery's been given another layer of cells, upping capacity from 11.6 kWh to 18.8 kWh. At the moment, Volvo's UK site advertises two figures for all-electric range on the WLTP cycle for the XC60 and XC90, and says the S90 can already do 90 kilometers on a charge. The spec pages, however, say the XC60 can do 32 kilometers maximum, the XC90 able to go 30 kilometers. With the new battery, Volvo says all-electric range has improved to up to 90 kilometers (56 miles) on the WLTP cycle, but that will surely depend on model. Our U.S.-market XC90 PHEV is EPA-rated at 18 miles of battery-electric driving. A 62% increase would put that at about 30 miles. Just as good as the battery boost, the 87-horsepower e-motor that powers the rear axle on the Recharge trims is goosed to 145 hp. The T6 Recharge powertrain will make 350 combined horsepower, ten horses more than currently, and the T8 Recharge powertrain will make a combined 455 hp, a considerable 65 horses more than now. That makes the coming T8 the most powerful Volvo ever put into series production. The T8's 2.0-liter twin-charged engine has also been engineered for more efficiency as well as "higher engine power at low revs and at start-up," but Volvo hasn't offered specifics on that yet.  Finally, drivers will be able to control all that go with just the accelerator pedal, Volvo adding single pedal drive on the XC60 Recharge, S90 Recharge, and V90 Recharge. There's no word on when we might see them; introduction sometime during the 2022 model year seems sensible. Related Video: This content is hosted by a third party.
