Volvo demos autonomous self-parking car concept

A number of companies are developing autonomous vehicle technology - Google and Audi come to mind - but Volvo is applying its work in the area to a particular usage case: parking. The Swedish automaker has the technology up and running in a concept vehicle, which it says can be dropped off at the curb by its owner and left to its own devices to enter and navigate a car park, then find and park in an available parking spot. Volvo says the process can even be reversed when the owner is ready to go, with the car leaving the car park on its own to meet its key-holder again at the curb.
The vehicle first interacts with Vehicle 2 Infrastructure technology, which places transmitters in the road itself to inform the car (and driver) if the self-parking service is available. The driver then hops out, activates the Self Parking function on his or her smartphone and then leaves the car to do its work. The car uses sensors, all seemingly hidden from view (an advancement of its own in this field), to autonomously navigate the car park, which includes interacting and adjusting to other cars, people and objects.
The technology used here builds off of Volvo's other work in autonomous vehicle research, namely the Safe Road Trains for the Environment (SARTRE) project in which the company managed to create a train of four cars autonomously following a lead truck at speeds up 56 miles per hour. Volvo says the first application of its autonomous research in a production vehicle will happen at the end of 2014 with some level of autonomous steering available in the next-generation XC90.

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.

Euro-market Volvo C40 Recharge and XC40 Recharge add efficiency, range

Volvo's tweaked the powertrain specs for the C40 Recharge and XC40 Recharge in Europe in both front- and all-wheel-drive trims. (We don't get the FWD versions here, only the AWD models.) First reported by CarsUK as a rumor, Autocar dug into the details after the new models hit some EU configurators. The big change there is that the front-drivers are now rear-drivers, engineers moving the single motor to the rear axle in the name of efficiency. The battery in the single-motor cars stays the same size at 67 kWh, but motor output rises from 228 horsepower to 235 hp. Even better, the C40 Recharge goes from an estimated 270 miles on a charge to 296 miles, the XC40 Recharge goes from an estimated 260 miles on a charge to 286 miles on the WLTP cycle. The AWD Recharge Twin trims get a larger battery, swapping the 78-kWh unit (75 kWh usable) for a 82-kWh unit (78 kWh usable). Their motors put out the same combined 402 hp as before, but do so with a rear bias. Instead of each motor making 201 hp, the front motor makes 161 hp, the rear 241 hp. Their ranges climb even more, the C40 gaining 37 miles of range to go an estimated 315 miles on a charge, the XC40 adding 42 miles to go an estimated 311 miles on the WLTP cycle. Volvo also upped the fast charging capability for the Recharge from 150 kW to 200 kW. The upgrade cuts the charge time from 10% to 80% by 10 minutes, to 27 minutes, matching the time required for the single-motor trims with the smaller battery to refill the same amount. The revised models can be ordered in Europe now but won't go into production until next year, the Recharge versions in May, the single-motor versions in autumn. Prices are up about 10%. It's thought the Polestar 2 will be in line for the same changes. We asked Volvo USA about the revisions coming to the U.S., aand  spokesperson responded, "We will have more details to share on the U.S. offer at a later date."
