Compression ratio question

While waiting for a haircut today, i was thumbing through car and driver. They had a mitsu evo, taurus sho, and on another page a 2010 911 turbo. All of these turbo version had 10.5 to 1 or higher compression ratio. How can newer cars have such high ratio, and the older cars had to have their compression lowered. I was stumped
