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 C30 Polestar Concept hits the 'Ring

It's been over three years since the Volvo C30 Polestar Concept was unveiled, driven by journalists and, as it turns out, lapped around the Nürburgring with Scandinavian Touring Car Championship driver Robert Dahlgren behind the wheel. For whatever reason, the video of the 'Ring track session was only published by the tuning company yesterday. (Another discrepancy: Did Polestar's C30 lose 46 horsepower somewhere along the line? Because the video states that it has 405 hp, while the company's website quotes 451 hp...)
Whatever the case, the tuned Volvo is a beast, much more so than the similar-looking, 250-hp 2013 Volvo C30 Polestar Limited Edition that was sold last year. With 451 hp (sounds better than 405 hp, doesn't it?), all-wheel drive, limited-slip differentials front and rear and Öhlins dampers, the Polestar Concept checks all of the right boxes for us.
For some reason, the video, which you can watch below, seems a bit vanilla to us. Perhaps the overly dramatic music takes away from the action and the beautiful sounds of the turbocharged five-cylinder engine?

Watch Volvo's V8 Supercar drivers play with the Polestar S60 in the Arctic

The Volvo S60 Polestar may not seem like a natural fit for the V8 Supercars series that runs throughout Australia, New Zealand and Tasmania. After all, the all-wheel-drive production-spec car isn't even available with a V8. But the rear-wheel-drive racing version has acquitted itself well in the early races of the season, even scoring an overall win at a race in Melbourne. Currently at seventh place in the championship, the S60 the most successful car that isn't a Holden or Ford.
To celebrate its burgeoning success, Volvo sent its V8 Supercars drivers Robert Dahlgren and Scott McLaughlin to home base in Sweden to have some fun driving in the snow and to visit Polestar headquarters. The two of them do some big power slides on an icy lake and then taker a deeper look into the company's performance division. Scroll down to watch the video full of sliding Swedish sedans.
