700-hp Hennessey CTS-V So Quick, OnStar Notices

by Jeff Prescott on

Hennessey Peformance Engineering Cadillac CTS-V700The latest high-performance creation from Hennessey Peformance Engineering (HPE) is so quick that OnStar was alerted by a recent acceleration test. In a video, posted by AutoBlog, a Cadillac CTS-V700 billed as a “four-door ZR-1” ran the quarter-mile in 11.07 seconds at 128 mph. In doing so, the musclebound CTS-V pulled .99 g, enough to alert OnStar that something beyond the norm for a production car was going on. A great nod to the performance accomplishment, an OnStar operator calls the car after the run and the driver reports all is fine. (Learn how OnStar works.)

The CTS-V700  with 20-inch drag radials claims a 10.9 second quarter-mile time at 129 mph. It blasts 0-60 mph in just 3.1 mph, reaching a 211 mph top speed.

The V700 package includes:

  • Four-inch cold-air induction system
  • Supercharger pulley and snout upgrade
  • Engine management software upgrade
  • Long tube 1 7/8-inch stainless-steel headers
  • Three-inch stainless mid pipes
  • High-flow catalytic converters
  • Intercooler heat exchanger system upgrade
  • V700 camshaft upgrade
  • V700 high-flow cylinder heads
  • 160-degree thermostat
  • Hennessey embroidered head rests
  • Serial numbered dash and engine plaques

Should that transformation sound too tame for your needs, HPE has an 800-horsepower twin-turbo CTS-V package. (Visit the HPE Web site.)
