When we were fortunate enough to have a Cadillac CTS-V for a week to review, we said it was "one of the finest cars on the road today and one of the best vehicles ever built by General Motors." Of course, there's always room for improvement. At least Hennessey Performance thinks so, and they have come up with the V700 upgrade package that boosts the supercharged 6.2-liter V8 to more than 700 horsepower.
What does it take to squeeze more than 150 more horsepower out of the LSA V8? Hennessey adds a cold air induction system, a smaller supercharger pulley, a new engine management system, long tube headers, three-inch exhaust system with high-flow cats, an upgraded intercooler, more aggressive cam, and high-flow heads.
The result? Horsepower is up to 707 at 6300 rpm, and torque is rated at 701 lb-ft. That all adds up to some impressive performance on-track, including a 0-60 mph time of just 3.3 seconds and a top speed of of 211 mph.
