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.

Future Polestar Volvo models could feature diesel, EV tech

Volvo's Polestar sub-brand has made the transition nicely from being the company's racing arm to building some seriously cool, Swedish cars. Now that it has a few models under its belt, it plans to grow larger and greener. The next-generation of Polestar-tuned vehicles are rumored to include high-performance hybrid and diesel powertrains.
While it still doesn't have the brand recognition of BMW M or Mercedes-Benz AMG, Polestar is on the growth path. It's representatives recently told Autoblog that its latest, tuned S60 and V60 models "mark the start of an extended production car model range." In addition to that expansion, Volvo has given its performance division a greater responsibility for engineering future vehicles, according to Autocar. It even helped develop the new Drive-E engine, which we quite liked when we took it for a spin in an S60.
Polestar's boss hinted at a hybrid model to Autocar, a move that seems obvious once you think about it. The Drive-E engine was designed from the beginning to accept hybrid layouts. The division's plan is to put and electric motor on the rear axle to both increase torque off the line and provide all-wheel drive. As Drive-E also offers diesel variants, that is in the cards as well for the future, but the company didn't go into much detail. Polestar appears to be the upcoming shooting star of the performance car world.

Man convicted of spying on truck maker Scania for the Russians

STOCKHOLM — A Swedish court on Wednesday sentenced a 47-year-old man to three years in prison for spying for Russia, which involved selling secret information from truck maker Scania. The court said it had found the man guilty of acquiring and selling the secret information from the truck maker to a Russian embassy official. The court acquitted the man of similar espionage charges at Geely-owned carmaker Volvo Cars. "To be convicted of espionage, it is required that Sweden's security can be damaged if the information benefits foreign powers," the court said in a statement. "The district court has ruled that this is the case with regard to the information that the man obtained from Scania, while it has not been proven that this is the case with regard to the information from Volvo." The court statement said the man regularly received cash at his meetings with the Russian embassy official, which it considered was compensation for the information provided. The man, who has denied wrongdoing, was apprehended whilst meeting the diplomat in a restaurant, having just received 27,800 Swedish krona ($3,242). He worked as a consultant for Volvo Cars in 2016 and 2017 and for Scania in 2018 and 2019, until he was arrested. The man's lawyer said he would appeal. Scania is owned by truck maker Traton.
