Audi S8 tuned to 640 hp by ABT Sportsline

Volkswagen Group tuning house ABT Sportsline debuted its latest version of Audi's flagship luxury-sport sedan, the Audi S8. The already quick sedan has received a facelift for the 2015 model year, as revealed a few months ago at the 2013 Frankfurt Motor Show, and it didn't take ABT Sportsline long to get their hands on the latest version. While Audi's changes to the exterior have been relatively mild, with restyled front and rear bumpers and a slightly redesigned grille, the tuning house once again focused on changes under the hood.

Chevrolet Spark EV tops EPA's fuel-economy rankings for 2014

The 2014 Chevrolet Spark EV has been named the most fuel-efficient vehicle by the EPA and the Department of Energy in a new ranking for 2014. The Spark EV returns a combined 119 mpg equivalent, achieving 128 mpg in the city and 109 mpg on the highway. Chevrolet's pure-electric hatch displaced last year's chart topper, the Scion 2013 iQ EV, with its 121 mpg equivalent rating, but the Scion is not offered for the 2014 model year, so it didn't make the list for the U.S.

One Lap of the Web: Metal Machine Mazdas

-- Someday, for some reason, you might find yourself in Jaworzno, Poland. And if you're there, you might drive down Grunwaldzka and make a right on Krolowej Jadwigi (we've never been to Jaworzno, actually) and end up at the Jeff Hanneman Circle Pit, a roundabout named after the late guitarist from Slayer and, therefore, the most badass road junction in the universe. The traffic circle could -- and should -- also double as a demolition derby for FSO Polonezes.
