Hennessey Performance Engineering has unveiled four new tuning packages for Cadillac's highly regarded CTS-V that produces 556 hp and 551 lb-ft of torque in stock form.
The base V600 package includes a supercharger pulley upgrade kit, a K&N air filter, and new engine management software. These tweaks allow the V600 CTS-V to produce 610 hp and 605 lb-ft of torque which enables the car to dash from 0-60 mph in 3.7 seconds before hitting a top speed of 195 mph.
For owners wanting a tad more performance, Hennessey offers a V650 package that boosts the engine's output to 650 hp and 641 lb-ft of torque. This package comes with everything mentioned in the V600 kit as well as 4" cold air induction system, stainless steel headers, a 3" stainless steel exhaust system, high flow catalytic converters, and an upgraded intercooler heat exchanger.

An insane V700 package includes everything from the V650 package as well as a new high performance camshaft and new high flow cylinder heads. With the V700 package, the CTS-V produces 700 hp and 701 lb-ft of torque. This allows the car to rip from 0-60 mph in just 3.1 seconds and reach a top speed of 211 mph.
Hennessy also offers a V800 package that features a custom twin-turbo system, external wastegates, blow-off valves, and a high-performance fuel system with upgraded injectors. Other changes include the addition of a Corsa stainless steel catback exhaust system, high flow cylinder heads, an upgraded camshaft, and new engine management software. Thanks to all these changes, the V800 package produces 800 hp and 780 lb-ft of torque.
