Hennessey tuned Cadillac CTS-V vs. Porsche 911 and Nissan GT-R [video]

Here are a couple of videos put out by Hennessey showing their Cadillac CTS-V Sport Wagon with automatic transmission doing the quarter-mile race against a 2011 Nissan GT-R and then a Porsche 911 turbo.

Both cars, of course, are heavily out muscled by the tuned CTS-V , now sporting 650 bhp (485 kW / 659 PS). And if you look closely at the numbers you'll find that the more than 150 horse advantage the CTS-V has over its rivals should be delivering more than those marginal gains it has over the 911 and the GT-R.

Actually, if you look at the 0 to 60 mph (96 km/h) numbers that Hennessey itself puts on the videos, that 2011 GT-R,with 485 bhp (362 kW / 492 PS) and 434 lb-ft (588 Nm) of torque, has the same 3.5 second time as the Hennessey CTS-V.

And the Hennessey CTS-V weighs 1,000 lbs (454 kg) more than the 911 - 4423 lbs (2006 kg) vs. 3474 lbs (1576 kg).

Slaloming on the track? The GT-R sports some impressive Nurburging numbers and the 911...well, it's harp-tight suspension is a matter of legend.

Okay, yes, the Hennessey CTS-V is a quick-footed American sport wagon.
