Hennessey has unveiled a new performance package for the Cadillac CTS-V Coupe.

Dubbed the V1000, the car features an aerodynamic carbon fiber body kit with a ventilated hood, a front splitter, a rear diffuser and aggressive side skirts. Other highlights include a lowered sport suspension, Brembo carbon ceramic brakes and a bespoke interior with premium leather upholstery and an Alcantara headliner.

Power comes from a twin-turbo 427 LS V8 which has been outfitted with high-flow cylinder heads, a new crankshaft, upgraded fuel injectors, an intercooler and a revised ECU. Thanks to these tweaks, the engine produces 1,000 hp (746 kW / 1,014 PS) and 950 lb-ft (1,286 Nm) of torque. This will reportedly enable the car to accelerate from 0-60 mph in 3.5 seconds, run the quarter mile in 10.9 seconds and hit a top speed of 230 mph (370 km/h).

Production will be limited to 12 units, but there's no word on pricing.
