It seems there is proof in the pudding. Subaru announced that in a final timed run on the Isle of Man TT Course, Mark Higgins driving a 2015 Subaru WRX STI (our 2014) breaks his lap record of the fabled 37-mile course with an average lap speed of 117.510 MPH (189.114 km/h) and a time of 19 minutes and 15 seconds. In Higgins’ record lap earlier this week, several errors caused him to lose time and he was determined to get more out of car. This new lap record breaks the 116.470 MPH average and time of 19:26 set Wednesday. The previous record of 115.36 MPH was set in 2011 in a WRX STI.

The run was completed in a U.S.-spec 2015 Subaru WRX STI.

“This was a great run when everything came together and I was able to do a much cleaner lap as I am still learning where I can go flat in this car,” said Mark Higgins. “I am really happy to beat the lap records set by John McGuiness in the Zero Bikes and the sidecar lap record as John was riding me about that! I can’t say enough about the new WRX STI and how much abuse it has taken as we have really ridden it hard over this course for three very fast runs and this is definitely not an easy course. The chassis on this new car is just night and day.”


The car Higgins drove is a stock U.S.-spec 2015 WRX STI, with the exception of an FIA-spec roll-cage, racing seat and harness, fire suppression system and modified springs and dampers to handle the sustained high speeds and changing conditions of the course. The Subaru WRX STI also featured Dunlop Direzza tires and a high decibel straight exhaust for crowd safety. The speed limiter was also removed from the car.
“I would like to thank Subaru for making this possible and also a big thanks to all the organizers and marshals who volunteer their time here and who made this drive happen and also made it a safe run,” Higgins added.

“We knew there was more speed in the car after Wednesday’s run and we are very happy the organizers made this happen today,” said Dominick Infante, National Manager of Product Communications, Subaru of America, Inc. “Mark was really flying on today’s lap and could show what the new chassis can do on a circuit as demanding as the Isle of Man TT.”


The event, which has been comprehensively risk assessed by both Subaru and the ACU, including consultation with all relevant parties, took place under full, closed road race conditions.
