Hennessey Performance is continuing its testing procedures for the 2013 Viper GTS-based Venom 700R which was announced about a year ago.

The Venom 700R package is compatible with both Viper and Viper GTS models and manages to squeeze 705 bhp (526 kW) at 4,400 rpm from the V10 8.4-liter engine. Torque figure is up to 695 lb-ft (941 Nm) and these changes are enough to grant the car with a 0-60 mph (0-96 km/h) run in 3.1 seconds. It will do the quarter mile in 10.7 seconds at 134 mph (215 km/h) and is capable of achieving a top speed of 216 mph (347 km/h).

To get to these figures, Hennessey had to install high-flow cylinder heads and stainless steel long tube headers, K&N air filter, three-inch stainless steel exhaust system and high-flow catalytic converters. Optional goodies include carbon fiber front splitter and canards, rear spoiler and wing, along with a rollbar, fire extinguisher, rear differential cooler and a Penske double adjustable coilover suspension.

The Venom 700R can also be configured with lightweight monoblock wheels and a five-point Sabelt racing harness. Other carbon fiber interior trim bits and pieces are available upon request, together with custom painted stripe options and various tuner badges.
