Storyline – The new-old Sonoma provides a technical challenge for Goodyear, Cup teams: The big news regarding this year’s Monster Energy NASCAR Cup race at Sonoma Raceway is that course will include "The Carousel" section again, extending the length of one lap from 1.99 to 2.52 miles and adding some tighter and more technical elements for teams to negotiate. Comparing it to the circuit’s other "full-time" road course at Watkins Glen, Sonoma was already the more technical, which necessitates Goodyear bringing one of the most tractive tread compounds in the 2019 tire lineup. Racing at Sonoma highlights tight turns, extreme braking into the corners and hard acceleration off, all of which put undue stress on the tires.
"Adding ‘The Carousel’ back should be a real popular move for racing at Sonoma," said Greg Stucker, Goodyear’s director of racing. "What that does is take an already technical road course and make it more so. The Carousel not only adds about a half-mile to the length of a lap, but it also adds more elevation change, another tight section of the course and an additional passing zone. We always seem to have great racing at Sonoma, and this should only add to the excitement."
