#48- Jimmie Johnson s sixth championship came in his 12th full season; Richard Petty and Dale Earnhardt won theirs in their 15th full season (full season meaning they started at least half of the races). Earnhardt s seventh title came in his 16th season, Pettys in his 19th, meaning Johnson has plenty of time left to match and surpass the record. Petty and Johnson were 38 years of age when they won their sixth championship, Earnhardt was 42.(more stats at ESPN.com )
