American tuner Hennessey Performance is no stranger to modifying already powerful cars into 1,000+ horsepower beasts.
Their latest project is called HPE1000 Twin Turbo CTS-V. Based on the next generation Cadillac CTS-V, which hits the streets later this year with 640+ hp and a top speed of nearly 200 mph, the Texas tuner takes this American high-performance saloon to new heights.
As the name suggests, the car has 1000 horsepower from a 6.2-litre twin-turbo V8, good for a top speed around 240 miles per hour.
Their previously tuned CTS-V VR1200 Twin Turbo coupe ran 221 mph on State Highway 130 and it was still pulling on when we ran out of road, told John Hennessey.
The production will be limited to 24 units for the 2016 model year and in addition to an updated engine, the car comes with upgrades like carbon-ceramic brakes, larger wheels and tyres, widebody upgrade allowing for wider tyres as well as custom interior upgrades.
HPE will also offer less powerful performance upgrades for the 2016 CTS-V, delivering 750-800 hp from the factory supercharged V8 engine.
