There are some further surprises in store for potential GT-R customers too, as Nissan is doing everything it can to discourage owners from modifying the GT-R in the future. Sophisticated data gathering devices have been installed to monitor performance parameters and detect any variance from the standard set-up. These include g-force sensors logging acceleration and braking and detectors recording combustion temperatures inside the engine. Any infringement discovered during routine software interrogations at the scheduled services could invalidate the factory warranty immediately.
