|2013 Ford Mustang Shelby GT500 vs. Chevrolet Camaro ZL1: Video||
The ultimate modern-day pony car war starts and ends with the new Chevrolet Camaro ZL1 and Ford Mustang Shelby GT500. These two cars are the epitome of modern American muscle cars utilizing the best that automotive technology has to offer. What everyone wants to know, despite the Shelby GT500 having an obvious 98-rear-wheel horsepower advantage over the Camaro ZL1, which one is apt to take home the checkered flag.
What it all comes down to in finding a true victor, is the type of tests that you put these two American muscle monsters through. The Shelby GT500, sporting the most powerful production-car V8 engine, is the obvious victor when it comes to straight-line 60 mph or even quarter mile runs. After-all, it is over 200 pounds lighter than the Camaro ZL1. Of course you better be a good driver to be able to claim a win over the ZL1 in a straight-line, it isn’t much of a pushover. Straight-line performance is not the tell-all as you will have Camaro ZL1 fans tell you. When it comes to the handling department, it seems the Camaro ZL1 is more of the conqueror.
So, you have the Shelby GT500 with and slight edge in power and the Camaro ZL1 with an edge in handling attributes. Which one would you take to the track confident to walk away in 1st place?
Hit up the comparison video below and check out some of the hard numbers Inside Line gets from these two vehicles.
|Stock 2012 Chevrolet Camaro ZL1 Burns Up quarter mile in 11.93 seconds||
Although we have yet to get our hands on the new 2012 Chevrolet Camaro ZL1, the abundance of Mustang vs. Camaro hype circulating over the internet tends to give us a virtual measuring stick without having to strap in the driver’s seat. The latest ‘virtual’ performance number to reach the interwebs is the new Camaro ZL1 burning up the quarter mile in 11.93 seconds in complete stock form.
Already, skeptics and Mustang fanatics have taken to forums to dispute the 11 second quarter mile figure highly anticipating the new 2013 Shelby GT500 to annihilate the Camaro ZL1’s time.
Chevrolet is this game to prove that their ZL1 is not a pushover and the video below attempts to etch that in the minds of all enthusiasts, no matter how much more horsepower (about 82 more) the new GT500 is packing.
What several sources have verified about the new Camaro ZL1’s 11-second run is that the vehicle used in the test was in fact using stock Goodyear Eagle F1 Supercar G:2 tires. Chevrolet was also quick to note that using Mickey Thompson drag tires, the ZL1 was able to knock about a tenth of a second off of the 11.93 second time.
Hit up the video time-slip video below followed by the press release from Chevrolet.
Camaro ZL1 Joins the 11-second Club
DETROIT – The 2012 Chevrolet Camaro ZL1 is officially in the “11-second” club, as engineers recently turned an 11.93-second/116-mph quarter-mile elapsed time run in a showroom-stock Camaro ZL1 automatic. A Camaro ZL1 manual ran an 11.96-second ET at 117 mph.
Only a few other production vehicles can run the quarter-mile as quickly as the ZL1. Fewer yet can also run 0-60 in 4 seconds, reach a top speed of 184 mph and lap the famous Nürburgring in 7:41.27 – all with the street-legal, factory-issued components and no time-consuming equipment adjustments at the racetrack.
“The ZL1 is great at everything and we’re very proud of that,” said Tony Roma, Camaro ZL1 program engineering manager. “You can take it to the drag strip and run 11-second quarter-miles all day long. You can also take it to a road course, where it’s balanced, handles well, and does exactly what you want – including lapping Virginia International Raceway’s Grand Course in under three minutes – and yet the ZL1 is sophisticated enough to use as a daily driver. It’s a supercar you can drive every day.”
For perspective, the Camaro ZL1 is so quick that some drivers who experiment with “drag radial” tires or full racing slicks may find themselves going too quick for most NHRA-sanctioned racetracks, where a five-point roll bar is required for vehicles running 11.49 or quicker. The 11.93-second ET in a stock ZL1 tested by the engineers wore the factory-issued Goodyear Eagle F1 Supercar G:2 tires developed specifically for it, putting the car only a scant 0.44-second away from that additional racing safety requirement.
Tuned for the drag strip
The original, special-order 1969 Camaro ZL1s are still revered for their legendary performance on the drag strip and Chevrolet was keenly aware that customers for the new, 21st century edition would undoubtedly test its straight-line mettle in quarter-mile increments.
The Camaro team re-engineered 30 percent of a Camaro 2SS to make the ZL1, including special modifications just for the drag strip.
“We know many of customers will take their ZL1 to the drag strip,” said Gordon Rojewski, driveline development engineer – and who is also an experienced drag racer and owner of a turbocharged, 920-horsepower street car. “Some may just go once, to experience the full potential of the 580-horsepower LSA engine. Others may be more serious, going every other weekend with a set of slicks in the trunk. As such, we set out to make sure the ZL1 would perform for them – on the first pass and on the 100th.”
For example, to withstand the heavy loads of repeated hard launches, the ZL1 features a stout 9.9-inch rear differential mounted in a robust cast iron center section. It also features a standard differential cooler that can lower the temperature by 100 degrees F for improved performance and longevity.
The ZL1 also features asymmetrical half-shafts: a 60mm hollow shaft on the right and a 33mm solid shaft on the left. The different torsional stiffness rates of the shafts work in conjunction with the limited-slip differential to minimize the chance of wheel hop at launch. Engineers modified the rear suspension, as well, to accommodate an 18-inch wheel, for owners who want to fit a set of drag-radials with taller sidewalls to improve their ETs.
Even the ZL1′s exclusive Performance Traction Management (PTM) was tuned for the drag-strip. It integrates third-generation Magnetic Ride Control, launch control, traction control, electronic stability control and electric power steering response to enhance performance. Launch control (manual transmission only) automatically modulates engine torque for the best-possible acceleration without excessive wheel spin. When the driver pushes the throttle to the floor, the system holds a predetermined engine speed until the driver releases the clutch. Then, the system modulates engine torque 1,000 times per second to maximize the available traction.
Mode 5 of launch control is uniquely calibrated for drag strips that use VHT or similar traction-enhancing compounds on the starting line. In addition to validating the system for the stock tires, engineers also tested it with 18- and 20-inch racing-type drag radial tires in anticipation of the specialty tires many drivers will use at the track. Drag radials are very soft and provide nearly the traction of a full racing slick, allowing the car to launch at a higher rpm without wheel spin, which can translate into an even quicker ET.
Proven with 1,000 hard launch tests
To test the chassis and suspension components to ensure they were up to repeated hard-start launches typical at the drag strip, engineers subjected the ZL1 to the grueling “Woodward Avenue Schedule” at the GM Milford Proving Ground.
Named for the famous cruising route that cuts north through Detroit’s suburbs and has been the venue for untold thousands of unofficial launch capability demonstrations since the 1960s, each test cycle is a hard-launch, standing-start drag race up to 100 mph. The ZL1 was subjected to 1,000 test cycles before its driveline was stamped “approved”.
“The Woodward Avenue Schedule was a really brutal test, but it told us the Camaro ZL1 would live up to the way we knew our customers would drive it on the track,” said Rojewski.
The Camaro ZL1 is on sale now with a suggested retail price of $54,995 – including a $900 destination charge. The 6L90 six-speed automatic transmission includes TapShift control and is a $1,185 option. The Camaro ZL1 convertible goes on sale this summer.

|GM Still Working On Fix For Chevy Camaro ZL1 Mystery Flaw||
A few weeks back we told you that GM had recalled all Camaro ZL1 models delivered to dealers (as well as one erroneously delivered to a customer) to address a mysterious and undefined “quality issue.” While rumors circulated that the problem was software-related, GM remained (and remains) silent on the details behind the recall and production halt. It’s even extended to dealer orders, so at the moment, you can’t even place an order for a 2012 Camaro ZL1.
In a conversation with Chevrolet spokesman Monte Doran, Autoblog has learned that a fix will be forthcoming “in weeks, not months.” While Doran didn’t elaborate on the problem or the solution, he did qualify that a “couple hundred” ZL1s had been built prior to the recall and production stoppage, and that all are currently back at GM’s Oshawa, Ontario plant awaiting resolution of the issue.
Depending upon how long it takes, GM may decide to halt 2012 production and begin building 2013 models when production resumes. While the delays are inconvenient for anyone awaiting delivery of a 2012 ZL1, there’s some comfort in the thought that “limited production” usually translates to “increased collectibility” down the line.
If you can’t wait for delivery of your uber-pony-car, the new 650-horsepower Mustang Shelby GT500s will begin hitting dealers soon. It promises to be a faster car for comparable money, if any Chevy loyalists are willing to cross brand lines.
|Motor Trend Pits The Camaro ZL1 Against The Mustang Boss 302 Laguna Seca||
There’s an old-if-incorrect saying that goes, “never bring a knife to a gun fight.” Truthfully, the outcome of a gun versus knife confrontation depends on a lot of different factors, but here’s something to consider: there’s always a chance that a shooter will miss, even at close range. There’s very little chance that someone armed with a knife will miss. The moral to the story, then, is that it’s best to never underestimate an opponent, no matter what he’s bringing to the party.
Such is the case with Motor Trend’s latest “Head 2 Head” video, which stacks the new Camaro ZL1 up against last year’s Boss 302 Laguna Seca edition. We’re not sure why Motor Trend chose the Boss 302 instead of the Shelby GT500, since the Boss gives up some 136 horsepower and 176 pound-feet of torque to the Camaro ZL1, but perhaps it was simply a case of having the Boss 302 in the garage. In any case, think of the Camaro as the .45 caliber handgun, while the Mustang Boss 302 is the boot knife.
On paper, it seems like no contest until you start to look at the numbers more closely. Sure, the ZL1 has more power, but it also weighs some 413 pounds more. That’s a lot of mass to carry into a corner, then accelerate out, so the number of corners will likely have an effect on the race’s outcome. On the other hand, the Camaro’s four-wheel-independent suspension gives it a distinct advantage over the Mustang’s live axle on a bumpy track.
In the end, the gun won this particular fight, but not by the margin you may have expected. The Camaro ZL1 lapped in 1:41.3, while the Boss 302 Laguna Seca lapped in 1:43.7. This round goes to the Camaro, but we can’t wait to see the ZL1 stacked up against the next generation, 650-horsepower Shelby GT500.

|Want More Proof That The 2012 Camaro ZL1 Will Be Overbuilt?||
Chevrolet’s Department 180 has one of the best job in all of automotive design: take a new product, then figure out what it takes to break it. Sometimes this is done on a chassis test rig, which simulates driving over rough pavement to the point of component failure. Other times, that involves bringing a car to a proving grounds, then driving it as hard as you can until something breaks.
Running a car at speed on a racetrack is a worst case scenario, since you’re often running the engine at or near redline for extended periods of time. You’re flogging the brakes and transmission, too, and even relatively short track sessions tell you a lot about what’s properly engineered and what isn’t.
Despite the claim of a 24-hour test, Chevy didn’t really run the new Camaro ZL1 WFO for 24 hours straight. Instead, they ran 40 minute test sessions at a rate of six per day, over a period of six days. That may not sound like much, but try driving a car at the limit for 40 minutes at a time. In most street cars, brakes will fade, transmission temps will rise to dangerous levels and even differential temps will get up there. There’s a good chance that something will fail, especially if your track car tips the scales at two tons.
While an off-the-dealer’s showroom floor Camaro ZL1 may not stand up to 24 hours of punishment at Daytona, or even 12 hours of hard driving at Sebring, without a few mods, it’s good to know that Chevy’s built the new uber-Camaro with track days in mind. Even those of us who’ll never run the 24 Hours of Le Mans still enjoy flogging cars at HPDE sessions when our budgets allow.
