As production of the European specification Nissan GT-R begins in its Tochigi plant in Japan this month, a raft of significant changes have been made to the car. Its hand-built 3.8-litre V6 twin-turbo engine has been fine-tuned. Additionally, Dunlop SP Sport 600 DSST tyres will be fitted as standard. The tyres combine grip and durability as demonstrated at a 'time-attack' lap of the Nurburgring, which yielded a time of seven minutes 29 seconds.
