Climbing into the GR-1 through the forward-and-upward swinging butterfly doors, the interior reveals a race-ready design.
The seats are carbon shells equipped with racing-style harnesses. All the instruments in the panel behind the steering wheel are analogue, a sign of the GR-1's 1960s heritage.
A digital speedometer reveals the car's modern pedigree, however, and a closer look shows there is plenty of gadgetry in the dash. The stereo can play MP3s and can record and playback, ostensibly so drivers can record notes about the track while they take practice laps. Noise-dampening frequencies give the GR-1 a quiet street ride.
Mounted in the center of the dash is the Tire IQ display. Sensors in the tires and a built-in accelerometer measure tire temperature and pressure, as well as cornering and braking g-forces, all of which is relayed to the driver and passenger in real-time.
