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 aligning model range into three families

Things have been slow in Gothenburg the past few years, but they're picking up speed. The only new model Volvo has released in the past four years since it was taken over by Geely - that being the V40 introduced in 2012 - started its development when the company was still under Ford's umbrella. But now the Swedish automaker is preparing to launch a volley of new models, and the new XC90 is only the starting point.
Volvo has set out to align its product portfolio into three model families - 40, 60 and 90 - each with three body-styles: sedan, wagon and crossover. (Volvo presented a tidy little table, which we've replicated below, to outline what it has in store.) That means a new S40 sedan and XC40 crossover as well as a replacement for the current V40 wagon, all to be based on a new platform shared with Geely. It also means replacements for the current S60, V60 and XC60 to be based on the modular SPA platform that underpins the new XC90, as well as a new S90 sedan to replace the S80 and a new V90 wagon to succeed the V70 and move it up-market above the V60.
All of these models are set to arrive within the next four years as Volvo moves to replace its entire lineup by 2019 and subsequently move to more competitive seven-to-eight-year product life-cycles. But as aggressively as Volvo is pursuing this renewal of its core models, they're not the only things Gothenburg has in store. Keep reading below to learn how Volvo's model line will flesh out over the coming years.

Volvo XC90 successor EV might have been outed in patent images

Motor1 found a trademark application Volvo filed at the EU Intellectual Property Office on June 13 to reserve the name "EXC90." A month later, the Worldscoop Forum for European car fans posted these images, sourced from the same government agency. We can't be certain the two filings are related, but circumstantial evidence points to this being the full-sized XC90's battery-electric successor that will be called the EXC90. Another circumstantial log for the fire is that Volvo ex-CEO Hakan Samuelsson said the coming family transport would start with a vowel. Based on yet another trademark filing from last year and Samuelsson saying Volvo would "give cars a name as you give a newborn child," we've been looking out for the name Embla. But hey, EXC90 Embla would cover all the bases, and it could differentiate the battery-electric XC90 from the hybrid version we know will continue to sell. Rolling with the possibility, the drawings show a crossover taking clear cues from both the current XC90 and the Volvo Concept Recharge design study from November of last year. The headlight design, sold grille and vertical lower intakes look traced from the Concept Recharge. The hood is much more upright, a la the retail XC90, as are the horizontal roof and full-figured sides. In back, the drawings diverge from the XC90 and the concept. The backlight is more raked than that on the XC90, meaning it's far more angled than the upright hatch on the concept. The C-shaped lights are more like units on Volvo sedans, unconnected to the upright light elements beside the hatch glass in the same way the XC90's and concept's are. Below that, there are no visible exhaust outlets, but the ICE-powered XC90 hides its outlets, too. Not long after posting these exterior shots, Worldscoop posted interior shots as well. These represent designs that differ from every Volvo interior save for the inset where the portrait-oriented infotainment screen goes. The left and right steering wheel spokes feature floating inserts. The instrument panel stretches a single vent across its width, removing the vertical vents next to the infotainment screen, and might be reminiscent of the unit in the Polestar in placing the HVAC controls at the bottom of the touchscreen.
