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.

Volvos will brake for bicyclists with new detection technology

Anyone who pedals a bicycle knows that one of the biggest dangers to riders is a motorized vehicle - Volvo estimates that nearly 50 percent of all cyclists killed in European traffic have collided with a car. In the United States alone, 618 riders lost their lives in bicycle/motor vehicle crashes in 2010, and the number of injuries surpassed 52,000.
To help drop those numbers, Volvo has just announced Cyclist Detection with full auto brake - a technology that detects and automatically applies a vehicle's brakes when a cyclist swerves in front of a moving car. The basic components of the system include a radar unit integrated into the front grille, a camera fitted in front of the interior rear-view mirror and a central control unit. The radar is tasked with seeing obstacles in front of the vehicle and calculating distance, while the camera is responsible to determine what the object is. The central control unit, with rapid processing capabilities, monitors and evaluates the situation.
The technology, which will be sold bundled with its Pedestrian Detection and called Pedestrian and Cyclist Detection, will automatically apply full braking when both the radar and camera confirm a pedestrian or cyclist are in the immediate path of the vehicle. According to the automaker, the technology will be offered on the Volvo V40, S60, V60, XC60, V70, XC70 and S80 models from mid-May in 2013.

Trade war tactics: How Volvo will land a cheap Chinese EV on U.S. shores

A made-in-China electric vehicle will hit U.S. dealers this summer offering power and efficiency similar to the Tesla Model Y, the world's best-selling EV, but for about $8,000 less. The EX30 from Volvo Cars, the Swedish luxury brand owned by China's Geely, foreshadows the fierce competitive threat U.S. automakers could face from Chinese EV manufacturers that have surged far ahead of global rivals, especially on affordability. The $35,000 window sticker of Volvo's compact SUV hits a sweet spot in the U.S. market, where most buyers cannot afford most EVs. The competitive price reflects an unusual combination of Geely's China-specific cost advantages and Volvo's ability to skirt U.S. tariffs on Chinese cars because it also has U.S. manufacturing operations, according to interviews with four sources familiar with Volvo and Geely strategy and several U.S. trade policy experts. Chinese EV makers can undercut global competitors largely because of the nation's domination of battery minerals mining and refining, as well as its long-standing commitment to EV development, including heavy government subsidies. In addition, Geely has slashed manufacturing costs by merging supply chains and sharing platforms and parts with Volvo and other Geely brands, according to two senior Geely managers, who spoke on condition of anonymity because they are not authorized to speak publicly. Despite its aggressive price, Volvo is targeting hefty profit margins on the EX30 of between 15% and 20% globally, said a third Geely source. China's EV dominance will be on display this week at the nation's premier auto show in Beijing. In the China market, the world's largest, dozens of domestic EV brands are fighting it out in a price war while foreign automakers have steadily lost market share. The intense competition has driven China's biggest EV makers, led by BYD, to accelerate exporting of EVs that can capture higher prices and profits in less competitive overseas markets. The EX30 will be among only a handful of China-made cars sold in the United States, none of them from Chinese brands. Vehicles from China currently face a 27.5% tariff and increasingly strident calls for higher trade barriers from U.S. automakers and their political allies. But Volvo is eligible for tariff refunds under a law that awards them to firms with U.S. manufacturing operations — such as VolvoÂ’s South Carolina plant — that also export similar products, according to U.S.
