Looks super nice!

Only a few days ago, veteran GM engineer and racer John Heinricy, executive director of GM performance car programs, took a bone-stock 2009 Cadillac CTS-V around the famous Nurburgring circuit in seven minutes, fifty-nine and thirty-two one hundredths seconds, making it the fastest production sedan ever to have lapped the ‘Ring circuit. They had to wait to make the announcement until the car could be shipped back to Detroit and demonstrated to the media at the GM Milford Proving Grounds.

Heinricy says the car was run on stock Michelin Pilot Sport 2 tires at standard inflation pressures of 32 psi, and that the car was heavier than stock due to the inclusion of a roll bar, driving seats, five-point harnesses, and fire extinguisher in the ****pit, about 4300 pounds. He said the car, an automatic left in Drive the entire lap, got airborne in several places around the track, and hit a top speed of 175 mph at redline (6200 rpm) in fifth gear, averaging well more than 90 mph all the way around the circuit.

The production 2009 CTS-V will have a larger grille for more cooling air flow, a power dome hood to accommodate the supercharger, and the usual V markings inside and out. It will be powered by a supercharged 6.2-liter GM smallblock engine now rated at 556 horsepower at 6100 rpm and 551 foot-pounds at 3800 rpm, higher than previous estimates. Transmission choices include a new 6L90 six-speed automatic with paddle shifters or a new short-throw Tremec 6060 six-speed manual. With the manual, the rear-end ratio will be 3.73:1, and with the automatic, 3.23:1. The former will have an unrestricted top speed of 191 mph, the latter, 175 mph. Cadillac says the CTS-V will run 0-60 mph in 3.9 seconds, a quarter-mile in 12.8 seconds at 118 mph, and push well into the .9g range on a skidpad.

The chassis of the CTS-V has been upgraded substantially compared to the previous version. A second-generation version of GM’s Magnetic Ride Control, using magnetic rheological shock absorbers, is standard equipment.

MRC uses a combination of electric current, magnets and a special fluid with precisely sized and shaped iron particles in each shock absorber body. GM-developed algorithms in the control electronics create the fastest-acting suspension in the world, capable of reading the road every millisecond, with each of the four corners operating independently of the other three, in combination with StabiliTrak yaw control, traction control, steering angle, brake pressure and other inputs.

The MRC 2.0 system has two modes, Touring and Sport; same algorithms, different calibrations. With a new type of magnetic fluid, and a new piston shape inside the shock, Cadillac engineers say that the soft setting can be softer, and the firm setting firmer, with a system that has more predictive capability based on data.

The suspension acts on Michelin Pilot Sport 2 tires, 285/35R-19 rear and 255/40R-19 front, on alloy wheels, with Brembo 370-mm six-piston front brakes and 365-millimter four-piston rear brakes, about an inch larger on each end than the last generation CTS-V brakes.

The entire rear axle and differential assembly has been upgraded to handle the torque. The driveshaft has a larger outside diameter and wall thickness to handle the additional torque, the limited-slip differential housing is made of cast iron, with offset mounts, and the half shafts are different sizes, 55 millimeters left and 35 millimeters right, to counteract the forces that create axle hop. It’s all mounted on a huge steel subframe to isolate it from the rest of the car.

The CTS-V will go on sale at the end of September, at an estimated price of $65,000, with a full range of options including navigation, a huge new sunroof, a Performance Traction Management system, and Recaro front bucket seats. GM plans to export the car to Europe, the Middle East and Asia for the first time.

this CTS should be very interesting indeed

^^^the fastest

But i like the caddy too

[Memphis]

They probably mean fastest production sedan lol.

[EVILZ33]

id say the flying spur with 600 hp

[01mmmz28]

Doubt its the fastest. I thought there was an Audi out there that was faster, not to mention a Merc or BMW.

[Memphis]

Just saw that Bent thing, 9 mph fasterter than them so it makes their(caddy) claim false. Its the quickest one out tho so maybe they should change their wording lol

I believe all those have got the 155mph limit thing going on

[EVILZ33]

i see those things everywhere here my dads friend as a flying spur ballin and pretty fast for a bigass car

very nice car , it won't be as fast as a german sedan , waiting to see it vs M5bmw or the E63 AMG , limiting the top speed on them to 155mph was the most fooked up thing germans did. without the limiter the brabus rocket got 225mph top speed , about the quickest it got 12.8 for the 1/4 mile , a bone stock E63 gets it in high 11's

[mattlikespeople]

nvm..........

[BOTLFEDLT1]

i think the basis for their claim was the time achieved at the ring and not top speed or acceleration.
