The new BMW M3 CS is here, featuring 543 horsepower with all-wheel drive and a carbon-fiber diet. Audi Activesphere Concept shows off its mini pickup-truck bed, and Porsche pays homage to the 356 with the Vision 357 Concept. We see images of the new Toyota Tacoma for South America, and a camouflaged prototype pickup spotted with a Fiat Strada rekindle rumors of a new midsize Ram truck.
