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 recommits to Sweden with development of next-gen platform and engines

Taking into account the facts that Volvo is now owned by China's Geely and how poorly the European automotive market has been recently, we would have definitely understood if Volvo moved production of its products out of its home market. And yet, the automaker has confirmed that it will be investing billions of dollars into new platforms and engines that will be made in Sweden. On a global scale, Volvo is making roughly $11 billion of investments, and close to half of that is being earmarked for Sweden for plant expansion and upgrades.
The new Scalable Product Architecture (SPA) platform will be the used as the basis for most future Volvo products starting with the next-generation XC90 that will be debuting at the end of 2014. SPA will be used to make up two-thirds of Volvo's sales, and gives Volvo a quicker and easier break from Ford-derived platforms. As for the Volvo Engine Architecture (VEA) family of engines, there are really no details about this mill except that it will be a four-cylinder that is more fuel efficient than current engines.

Recharge Wrap-up: Green Car award for Volvo XC90, MN air better from biodiesel

The Honda CR-V could return with a plug-in hybrid option. Expected to debut in the fall of 2017, the PHEV could use a 2.0-liter I4 plus an electric motor. It's possible that the new CR-V is being developed in North America, and will borrow design cues from the Honda Civic. There also could be a seven-seat version. Beyond that, details are pretty scarce. Read more at Hybrid Cars, and from Response JP. UC Davis will present findings from a CARB-commissioned study on customer valuation of zero-emission vehicles (ZEVs). Dr. Ken Kurani of the university's Institute of Transportation Studies will report on consumer attitudes toward ZEVs, and the differences between those valuations and market behavior. In Kurani's survey, respondents had the opportunity to design their own car with an in-survey game. Almost a quarter of people designed some sort of EV, including plug-in hybrids and fuel cell vehicles. Read more from CARB, or at Green Car Congress. Minnesota's biodiesel efforts have improved air quality. According to the American Lung Association in Minnesota, summer and winter blends of biodiesel have prevented the emission of 130 tons of particulate matter, 319 tons of hydrocarbon and 2,634 tons of carbon monoxide every year, as well as a total of 3.7 million tons of CO2 over the last 10 years. Minnesota requires a B10 biodiesel blend during the summer months, and B5 throughout the winter. Read more from Biodiesel Magazine. The Volvo XC90 has received the Canadian Green Car Award for Most Efficient Three-Row Family Vehicle. Beating out the Ford Explorer 2.3-liter EcoBoost and the Honda Pilot, Volvo's seven-seat crossover was chosen for its mass market appeal, and a variety of qualities both practical and green. Judges look at value, fuel economy, emissions, performance and technology among other features. The XC90 is available as a plug-in hybrid with about 17 miles of all-electric driving range.
