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.

Volvo S60 Polestar concept plays in the snow with Mercedes C63 AMG

Chris Harris took to a snowy stretch of tarmac to get a fingertips-on-the-wheel feel of the Volvo S60 Polestar concept. Harris says the turbocharged sedan with 508 horsepower and 424 pound-feet of torque - and a manual transmission - is "a study to see if Volvo can get back into the fast-car market." The Polestar S60 concept, one of which was already purchased for $300,000 by a private buyer, is still making the publicity rounds because even Volvo's Chinese owners realize that, as Harris says, "Volvo sold more cars because it made fast cars" like the old 850 T5 Wagon that stormed the British Touring Car Championship in the 1990s.
For reference, Harris compares the blue wonder to the Mercedes-Benz C63 AMG and its 487 hp and 442 lb-ft. The question is, were Volvo to get the price of a production version of the S60 Polestar to climb way down from its 200,000-pound sticker, could it be worthy competition to the established giants?
You can watch Harris divine the answer via a lot of drifting through the snow and a drag race in the video below.

Recharge Wrap-up: video touts Volvo electric buses, Nissan and BMW build EV chargers in S. Africa

Volvo is touting the advantages of electric buses in a new video. The short film, called Route 55, promotes the ElectriCity Project for public transport, and, more specifically, the new electric bus route in Gothenburg, Sweden. The new route debuts June 15 using Volvo electric and hybrid buses. In the video, two teenagers are seen waiting for the bus. As one boards, the other asks her out from the sidewalk, but she can't hear him over the noise of the diesel bus, which then closes its doors and drives away. The film asks, "What if this bus had been silent?" See the video above, and read more in the press release below. BMW and Nissan will build an EV charging network across South Africa. Through 2017, the two automakers will build fast-charging and AC stations around the country in order to encourage the adoption of EVs. Nissan has been selling the Leaf in South Africa since 2013, and BMW introduced the i3 and i8 in March. "In order for the introduction and expansion of electric vehicles as well as plug-in hybrid electric vehicles to be successful in this market, we need to work together," says BMW South Africa Managing Director Tim Abbott.

The fleet of vehicles includes the Nissan Leaf and e-NV200, as well as the Renault ZOE, Kangoo ZE and Fluence ZE. The entire passenger car shuttle fleet will use all-electric vehicles as some 20,000 UN attendees descend upon Paris from November 30 to December 11. "Thanks to the Alliance's fleet of 100-percent electric vehicles, it will contribute to our goal of achieving a carbon neutral event," says French Minister of Foreign Affairs and International Development and COP21 President Laurent Fabius. "The technology of electric vehicles helps reduce greenhouse gases in the transportation sector efficiently." Read more from Renault. Visa will be the official title sponsor of the Formula E London ePrix. Officially called the "2015 FIA Formula E Visa London ePrix," the races on June 27 and 28 will be the last of the electric racing series's inaugural season. Visa Europe will award the Visa Fastest Lap trophy after the each round, and will have interactive activities at the race's eVillage.
