Hennessey has released a new promotional video for their upcoming tuning program for the Chevrolet SS.

The company is keeping specifications a closely guarded secret but they confirmed the model was equipped with the HPE600 Supercharged package which enabled the car to hit a limited top speed of 163 mph (262 km/h) on the Grand Parkway toll road near Houston, Texas.

Hennessey hasn't released details about the HPE600 package but their website says the tuning program for the Chevrolet SS will include "high flow air induction systems, engine management tuning upgrades, high-flow intercooler systems, exhaust system upgrades, turbo system upgrades, Brembo brake upgrades, suspension upgrades and wheel and tire upgrades."

If that sounds like overkill, the standard model has a 6.2-liter V8 engine that develops 415 bhp (310 kW) and 415 lb-ft (563 Nm) of torque. It is connected to a six-speed automatic transmission which enables the sedan to accelerate from 0-60 mph in approximately five seconds.
