The Subaru WRX STI has once again broken the four-wheeled lap record around the famous Isle of Man TT circuit, with British rally champion Mark Higgins setting a new record of 19 minutes 26 seconds in a production version of the new STI.
Higgins’s lap around the challenging 60.8 km TT Mountain course saw him post an average speed of 187 km/h and a top speed of over 257 km/h.
The Manxman completed his timed run under closed road conditions as part of the TT schedule and beat his previous record, set in 2011, when he did 19 minutes 56.7 seconds. That was done at the wheel of the previous-generation WRX STI, breaking a record that had stood for 21 years.
As with the previous record-breaking car, the WRX STI used for Higgins’s run was a standard US-spec car, equipped with a 300 PS 2.5 litre turbo boxer engine. The only mods involved the springs and dampers, which were adjusted to minimise any potential damage from the course’s many high speed bumps and jumps.
The WRX STI (Impreza name now dropped) was also equipped with essential safety enhancements, including a roll-cage, race harness and fire suppression system and was fitted with Dunlop Direzza tyres.
“It was quite a lap we did today and I am really happy to have another record in the bank. The chassis of the new car is so much better it really allowed me to pick up time in each sector in the more technical parts of the course,” Higgins said.
“There is nothing like the TT course in all racing. Not just because of its length but the elevation changes, constant surface variations as you shift from town to country roads and the fact we run from 48 km/h and then up to 257 km/h plus for much of the race,” he added.
