We don’t usually feature American cars all that often. But we had to look at this one, you understand. Texas-based tuning company Hennessey Performance bears no relation whatsoever to the cognac (that’s spelt ‘Hennessy’) but we do wonder what these guys put in their drink. In 2010, they released the Hennessey Venom GT – essentially a 6.2 litre twin-turbo LS9 V8 in a Lotus Exige chassis, whacking out 1,200 hp and 1,564 Nm of torque.

As if that wasn’t enough, here comes the VR1200 Twin Turbo Coupe, based on the two-door Cadillac CTS-V. Limited to just 12 vehicles, this monster packs a 7.0 litre twin-turbo aluminium V8 with three adjustable boost levels that allow 800, 1,000 and the magical 1,226 hp (of which 1,066 goes to the rear wheels). Torque is an equally mental 1,501 Nm. As a result, 0-100 km/h is dealt with in a blistering 2.9 seconds and the car will go on to a theoretical top speed of 387 km/h.

The engine features forged pistons, connecting rods and crankshaft, as well as high-flow cylinder heads and air induction. The twin-ball bearing, billet wheel precision turbochargers have dual wastegates and an air-to-water intercooler. Watch the car strut its stuff on the dyno in the video below:

Other noteworthy upgrades are to the suspension (lowered and tuned), brakes (we certainly hope so!) and transmission. The CarbonAero wide-body kit, made mostly of carbon fibre, widens the rear of the car by 178 mm and the front by 76 mm.

How much? Including the price of the base car and excluding shipping costs, US$295k (RM915k). If you want, they’ll do up the CTS sedan and wagon to this spec too. Whatever it is, this Caddy sure has come a long way from this one…

Recently the state of Texas raised the speed limit on a stretch of road between Austin and San Antonio to 85 mph (136 km/h), making it the highest in the States. Still not high enough, apparently, for some Texans.
