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.

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."

Top torque-to-weight ratios under $100k, $50k and $25k

Horsepower may steal a lot of headlines, but the always-more-complex torque figure is often a critical one for both the workingman and the motoring playboy. The measure of rotational force represents the twist that can liquefy one's tires or haul one's horse trailer. Good stuff.
It follows then, that as with the horsepower-to-weight list that we assembled for you a few months ago, a list of cars that offer the most pound-feet with the fewest pounds to carry, is an interesting one to break down. Sure, there's a big difference in how the torque is applied from a turbocharged six-cylinder in a Swedish luxury sedan and a massive heavy-duty truck's turbo-diesel. But being the car/stat geeks that we are, we think it's kinda neat that those two vehicles rank near each other where torque and weight intersect.
As with the horsepower list, we've given you figures as pounds per every one pound-foot. Again broken down into broad price categories, we've got a mixed bag of 2014 and 2015 models here, too. Every effort has been made to select the most up-to-date prices and specs, and we've also to omitted some '14 cars that won't be re-upped after the ongoing yearly changeover.
