All that thrust is sent to the front wheels through a six-speed manual transmission equipped with a limited-slip differential. In performance testing, the Speed 3 went from zero to 60 mph in 6.3 seconds, quick for its class. EPA-estimated fuel economy is 18 mpg city/25 mpg highway and 21 mpg combined.
