Volvo specs new 450-hp triple-charged four-cylinder engine

When Volvo lifted the veil on the new XC90 a little over a month ago, it announced that all versions would be powered by one engine design: a new 2.0-liter four-cylinder to be offered in various states of tune. That would range, Volvo said, all the way up to a high-output version with "around 400 horsepower," but while it wouldn't specify exact output, now it has.
The new High Performance Drive-E Powertrain incorporates two parallel turbochargers fed by a third electric turbo-compressor. Instead of feeding the cylinders directly, that third unit spools up the twin turbochargers, working together with a dual fuel pump pressurized to 250 bar.
The result is an output of 450 horsepower - far more than the existing 320-hp version and even more than expected. That also works out to 225 hp/liter, far more than the 177 hp/liter boasted by Mercedes-AMG's high-output turbo four and the 139 hp/liter in the Alfa Romeo 4C. Short of a rotary engine (whose actual displacement is the subject of great debate), you'd have to go up to something like the Koenigsegg One:1 (268 hp/liter) to find a higher specific output than what Volvo's boasting here.

Child cobalt miners: Automakers pledge ethical minerals sourcing for EVs

BERLIN - Leading carmakers including Volkswagen and Toyota pledged on Wednesday to uphold ethical and socially responsible standards in their purchases of minerals for an expected boom in electric vehicle production. Demand for minerals such as cobalt, graphite and lithium is forecast to soar in the coming years as governments crack down on vehicle pollution and carmakers step up their investments in electric models. To cover its plans for more than 80 new models by 2025, Volkswagen alone is looking for partners in China, Europe and North America to provide battery cells and related technology worth more than 50 billion euros ($59 billion). Talks with major cobalt producers, including Glencore, at VW's Wolfsburg headquarters last week ended without a deal. More than half of the world's cobalt comes from the Democratic Republic of Congo, a country racked by political instability and legal opacity, and where child labor is used in mines. On Wednesday, a group of 10 leading passenger-car and truck manufacturers announced an initiative to jointly identify and address ethical, environmental, human and labor rights issues in raw materials sourcing. The partnership dubbed "Drive Sustainability" consists of VW, Toyota Motor Europe, Ford, Daimler, BMW, Honda, Jaguar Land Rover, Volvo Cars and truckmakers Scania and Volvo. The alliance "will assess the risks posed by the top raw materials (such as mica, cobalt, rubber and leather) in the automotive sector," said Stefan Crets of the CSR Europe business network. "This will allow Drive Sustainability to identify the most impactful activities to pursue" to address issues within the supply chain.Reporting by Andreas Cremer.Related Video: Image Credit: Michael Robinson Chavez/The Washington Post via Getty Images Green BMW Ford Honda Jaguar Land Rover Mercedes-Benz Automakers Toyota Volkswagen Volvo Green Automakers Green Culture Electric Scania ethics mining

IIHS says these are the safest cars of 2013

The Insurance Institute for Highway Safety (IIHS) has revealed its annual list of Top Safety Picks, an award that highlights automobiles it says offer "superior crash protection." A new and still more significant award, the Top Safety Pick+ honor, is given to those vehicles that earn good ratings for occupant protection in four out of five areas of measure. And while some 117 vehicles were given the TSP seal of approval for 2013, just 13 passed muster for TSP+.
To be fair, IIHS only evaluated 29 vehicles with its new testing procedures for TSP+ (we'd expect that the number of qualified cars will rise substantially for 2014). Luxury and Near Luxury midsize cars were the first groups evaluated, followed by midsizers in the Moderately Priced Cars category - unsurprisingly, it's only midsize cars that you'll find among the class this year.
Only two luxury sedans made the list of 13 for 2013: the Acura TL and Volvo S60. The other 11 cars on the list included entries from domestic, Japanese and German car makers: Dodge Avenger, Chrysler 200, Ford Fusion, Honda Accord (sedan and coupe), Kia Optima (but not its close kin, the Hyundai Sonata, strangely), Nissan Altima, Subaru Legacy and Outback, Suzuki Kizashi and the Volkswagen Passat all made the grade.
