One good thing about Hennessey Performance, America’s biggest tuner, is that they always put their money where their mouth is! So when they tell you that they managed to squeeze 650 hp out of Cadillac CTS-V Sport Wagon family car, they can actually prove it to you. And what better way of proving that than a good old drag race! Here they put the Caddy Wagon up against a brand new Nissan GTR, a full-blooded performance machine. Hit the play and see the result.
