Of course, today's muscle car isn't all about Go
Today's cars are also about how they handle.

Here is how they stack up in this area:

Chevrolet Corvette Z06
60-0 Braking: 107 ft.
SkidPad: 0.94g
Slalom: 68.5 mph

Cadillac CTS-V
60-0 Braking: 115 ft.
SkidPad: 0.87g
Slalom: 66.0 mph

Ford SVT Mustang Cobra
60-0 Braking: 121 ft.
SkidPad: 0.88g
Slalom: 65.6 mph

Cadillac XLR
60-0 Braking: 125 ft.
SkidPad: 0.87g
Slalom: 64.9 mph

Chevrolet Corvette
60-0 Braking: 134 ft.
SkidPad: 0.89g
Slalom: 62.4 mph

Pontiac GTO
60-0 Braking: 121 ft.
SkidPad: 0.84g
Slalom: 63.0 mph

Chrysler 300C
60-0 Braking: 126 ft.
SkidPad: 0.79g
Slalom: 62.4 mph

Handling is close enough that it will come down to the driver in every case!


Not sure why the XLR was grouped with "muscle cars"
but interesting how it stacked up :thumbs

All in all a good group to be running with.

I can vouch for the SVT Cobra, I sold a 2003 model just prior to picking up my XLR (no more garage space). A few simple bolt-on parts (cold air intake, exhaust, chip and S/C pulley swap) and mine was running the 1/4 mile in the very low 12 second range all day long. Came with pretty strong brakes and decent suspension, all for less than $35,000. Not a bad package if you want a performance car for the weekend.

Mods on your XLR

Hi Pit Crew:

My dealer, Allen Cadillac, mentioned to me that they have a mod package that consists of exhaust and cold air intake: Around $1,400.00 he said.
What is the "chip" and "S/C pulley" all about?
Can you give more details please?
Did your mod cost $35,000.00 ?
I'd love to operate the 1/4 mile in the 12 second range, but not at that price.

If you could share that info, alot of us would appreciate it, unless you're racing for "Pink Slips" and consider it classified.

Many Thanks,

Brooks

P.S. Your photo: 5,600 RPM/150 MPH is a classic.
When questioned about how it was accomplished, your response, "With the other hand" was classic too!
Speaks volumes about the handling characteristics of the XLR.
Those of us who have raced appreciate it.

I guess I didn't explain myself well enough. I was speaking of modifications to a 2003 SVT Cobra, not an XLR. Since the Cobra is factory-equipped with a supercharger, changing the pulley ($150-250) to a smaller one adds boost, hense more horsepower. A performance chip ($450) adds power as does the CAI ($200-300) and exhaust ($350-500). Added together they will push the Cobra to numbers as low as high 11's // low 12's 1/4 mile times.

If your dealer is offering mods for the XLR I'd be curious as to what they are. A few of our members here have modified theirs (I've added K&N filters to mine) and there are pending mods available, however I'd love to know more about what's out there.

XLR Mods

Sorry I misunderstood you and thanks for the clarification.
I've got a query going with my dealer on the exhaust and cold air mods and will post it to you when available.
What are K and N filters?

K&N makes a direct replacement filter element that will work on our car. They will allow a bit more air flow which equates to a bit quicker throttle response.
