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 Polestar reveals new V8 Supercars engine

Volvo may be better known for turbo fives and inline fours, but in 2005 it launched the XC90 with a new eight-cylinder engine built for it by Yamaha. Fast forward to this past June when Volvo announced its intention to enter Australia's V8 Supercars series, where it would compete with the likes of Ford, Holden, Nissan and Mercedes-AMG. This is the engine with which it intends to do so.
Revealed this weekend at the Sydney 500, this competition-spec powerplant is based on the same B8444S that powered the XC90 and S80 (not to mention the Noble M600), but tuned for racing duty to be shoehorned into the new S60 touring car. The 60-degree aluminum block has been bored out from 4.4 liters to 5.0, its compression ratio boosted to 10:1, modified to run on E85 bio-ethanol and its redline increased to 7500 rpm. Volvo also promises a unique engine note from its new racers.
While Volvo and its racing partner Polestar haven't released official output numbers, regulations call for outputs between 620 and 650 horsepower - in any event, a whole lot more than the 311 hp it produces in stock form. (Noble managed to squeeze that much out of the same block, but that required twin turbochargers while this unit remains naturally aspirated.) Scope out the details in the press release below and the photos from the reveal in the gallery above.

Volvo building new AstaZero safety proving ground in Sweden

Volvo is an automaker committed to vehicle safety, setting an ambitious target for itself: by 2020, the Swedish automaker envisions that no one will be killed or seriously injured in one of its cars. In order to achieve that goal, Volvo has announced a new proving ground designed specifically to test safety solutions.
Called AstaZero, the new facility near the company's headquarters in Gothenburg, Sweden, is the result of a $70 million investment. It will cover some 500 acres, with over 60 acres of pavement, four city blocks and three and a half miles of highway. The Active Safety Test Area (the ASTA in AstaZero) will enable Volvo and its partners (including Scania trucks as well as government bodies and university development programs) to simulate city streets, highways, rural roads, roundabouts, T-junctions and more, combining traffic from cars, pedestrians, bicycles, motorcycles, buses, trucks and even animals in order to account for all manner of potential hazards.
The facility will enable Volvo to test active safety systems and autonomous vehicle operations, and even allow robots to test its prototypes in an adaptive environment that aims to be more flexible than existing proving grounds.
