We showed you an initial concept sketch of the Hennessey Venom GT last month, and the tuner best known for building ridiculously powerful Dodge Vipers has released another pair of pics, this time showing the mid-engine concept's rear with its retractable spoiler both up and down. In our previous post, we mentioned the undeniable likeness that the Venom GT shares with the Lotus Elise, which is also on display from this angle. We can also see just how extreme the car's design is, with a carbon fiber rear diffuser that we're sure isn't just for show and twin tail pipes that exit up high between the taillights. Carbon fiber skirts also peek out the sides below the massive air intake for the mid-mounted twin-turbo Viper engine and the extra-wide air extractor vents behind the front wheels. It seems clear to us that Hennessey intends to make a go of building its own exotic, just like Saleen did with the S7, and we hear two cars will be built to show potential customers in 2009. With a power-to-weight ratio of 2.7 lbs. per horsepower, a 2,700 lbs. curb weight, and an estimated 0-62 time of 2.5 seconds, we don't expect the Venom GT will be a tough sell.
