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.

Geely wants to be a tech-sharing 'friend' of Daimler in $9B bet

Chinese carmaker Geely has built up an almost 10-percent stake in Daimler in a $9 billion bet by its chairman that he can access the Mercedes-Benz owner's technology in the growing battle for the future of automotives. The purchase by Li Shufu, Geely's founder and main owner, means China's largest privately-owned automaker is now the biggest shareholder in Germany's Daimler. Geely said on Saturday there were no plans "for the time being" to raise the stake further. Instead, it will seek to forge an alliance with Daimler, which is developing electric and self-driving vehicles, to respond to the challenge from new competitors such as Tesla, Google and Uber. "No current car industry player is likely to win this battle against the invaders from outside without friends. To achieve and assert technological leadership, one has to adapt a new way of thinking in terms of sharing and combining strength. My investment in Daimler reflects this vision," Li said. "Daimler is pleased to announce that with Li Shufu it could win another long-term orientated shareholder, which is convinced by Daimler's innovation strength, strategy and future potential," the German company said in a statement. Geely officials plan to travel to Stuttgart to meet Daimler executives early next week and also hope to meet top German government officials in Berlin, two sources familiar with the matter told Reuters. The Chinese firm plans to use the meetings to underline that it intends to be a supportive long-term investor, they said. Daimler had no immediate comment on any meetings. Geely and the German economy ministry declined to comment. Chinese investors in German technology companies have tended to take a consensual approach, buying incremental stakes in companies such as robotics firms Kuka and Kion, typically after long consultation with management and other stakeholders. In November, Geely asked Daimler to issue new shares so it could buy a stake, as a way to access Mercedes-Benz technology for electric cars and trucks, including battery technology, to help Geely comply with a Chinese crackdown on pollution. But the German company turned down the offer saying it did not want to dilute existing shareholders, sources at the time told Reuters. Li changed tactics, and quietly amassed a stake of 9.69 percent worth $9 billion at Daimler's current share price.

Volvo Concept Coupe may see limited production

Despite the impressive production debuts from Porsche and BMW at this year's Frankfurt Motor Show - the 918 Spyder and the i8, respectively - there was one car that captured the attention of the press and the public alike, enough so that we awarded it our overall top pick of the show: the Volvo Concept Coupe. Most concepts never make it to production, but the car's reception has been so positive that Volvo's board of directors is considering to produce it in limited quantities, Auto Bild reports. Italian coachbuilder Bertone could handle the limited production run.
Styled after the classic P1800, the Volvo concept was similar to the new Porsche and BMW in that it was equipped with a high-performance hybrid drivetrain. But Volvo took a different route from there, giving the sleek coupe a turbocharged and supercharged 2.0-liter four-cylinder engine paired with an electric motor at the rear axle. All in, the combo is good for 400 horsepower and 490 pound-feet of torque.
If the Concept Coupe makes it to production, it may not get the trick hybrid drivetrain mentioned above, Motor Athority reports, but a milder plug-in hybrid setup or even just a conventional fuel-burning engine. In any case, it would be a treat if Volvo produced a fully functional, street-legal Concept Coupe, though at that point we're thinking it would be due for a name change.
