The car tested at Millbrook (pictured) is the same vehicle appearing at Goodwood, featuring the GT-R's 3.8-litre twin-turbo V6 that is now confirmed to be rated at 424kW in the Infiniti application – more than enough to see off the larger M5 in pure power terms. Getting behind the wheel for the Goodwood jaunt, in the 'First Glance' category, will be Infiniti Red Bull Racing team principal Christian Horner, and his test and reserve driver, Sebastian Buemi.
