The XP-1's curb weight is 2,751 pounds (1,248 kg) typical of many other gasoline-powered supercars in its class, helped by an ultra-light carbon-titanium monocoque chassis.

The range of the XP-1 is longer than other hydrogen-powered vehicles such as the Toyota Mirai or the Honda Clarity due to its larger hydrogen tank.

Hyperion states a top speed of 221 miles per hour (356 km/h) and a 0 to 60 mph (0 to 97 km/h) acceleration time of 2.2 seconds.

[2] The XP-1 comes with a three-speed automatic transmission, and will use ultracapacitors to increase the power output of the fuel cell to the electric motors.

[3] As of April 2024[update], production had not yet begun, and one of seven development prototypes—fitted with a battery–electric powertrain and not hydrogen—was offered for auction by Hyperion.
