Autoweek chimes in as the first US mag to cover the MINI's 2005 changes:
Mini is upping the supercharged Cooper S to 170 hp and 162 lb-ft of torque and lowering gearing to boost performance.
The S now scurries from 0 to 62 mph in 7.2 seconds and hits a top speed of 138 mph (previously 7.4 seconds and 133 mph). Squeezing an extra 7 hp and 7 lb-ft out of the supercharged 1.6-liter four also helps offset the extra 220 pounds in the Cooper S Convertible, which makes its world debut at the British motor show this month. The convertible and coupe arrive in the United States this fall.
Revised gearing makes a difference, too, with the reduced ratios for third, fourth and fifth gears on the S. A five-speed Getrag gearbox replaces a Rover-derived unit on the regular Cooper.
To my knowledge this is the first time we've seen specifics regarding which gears are getting the reduced ratios.
