The Devil Inside

The test of Chevrolet Camaro ZL1 and Z/28  that silenced the critics was the test at Nurburgring.  When you see how it stacks up against the absolute greatest production cars ever made, you see that dollar for dollar it is in a class by itself.  The only competition for under $100,000.00 are the Corvette ZR1 C6Z07 and C6Z06, .

 

2014 Chevrolet Camaro Z/28 and 2013 Chevrolet Camaro respectively, posted the 36th and 45th fastest times EVER at Nurburging at the time they were built ! That's haulin ass for production muscle cars ! I just added a new sheet updated as of 11/14/2014. You will notice that there is no Shelby 500 GT, or Chrysler Hellcat SRT in the top 101 cars.  The 'Ring is Camaro's house !Yell


 

General Motors performance engineering is truly world class again.

The only 2 cars I ever want are Corvette and Camaro.  I was not overwhelmed with the new 5th generation Camaro at all compared to the 6th generation Corvette.  ZL1 changed my mind.  I'm sure the forthcoming 2014 Camaro Z28 will follow the example of the ZL1.

 

 

DETROIT – With supercar levels of performance and technology, the 580-horsepower Camaro ZL1 can reach 174 mph  on the famed Nürburgring’s Nordschleife course in Germany. To maintain stability and steering response at that speed, the ZL1 features an aerodynamic design that generates downforce to press the tires against the track.

“The Camaro ZL1 lapped the Nürburgring in an incredible 7:41.27 seconds, which would not have been possible without work of our aerodynamics team,” said Al Oppenheiser, Camaro chief engineer. “The design of the ZL1 creates downforce like a race car, harnessing air pressure to press the tires against the track for extra grip and control at high speeds.”

 

For the ZL1 – the fastest Camaro ever – the aerodynamics team set out to generate downforce for improved handing at speed while minimizing the amount of increased drag that could reduce fuel economy and the vehicle’s top speed. With the computer-assisted design recommendations, engineers tested full-scale clay models and full-size prototypes in the General Motors’ wind tunnel – shaping clay and trimming foam board by hand to affect changes and measure them immediately.  

Outside of the aerodynamics laboratory, engineers tested the ZL1’s aero aids on GM’s Milford Road Course, other race tracks and the unique “rolling road” wind tunnel at the Auto Research Center in Indianapolis.

When the dust settled and the wind-tunnel blades came to a stop, the Camaro ZL1 produced 65 pounds of downforce at an equivalent 150 mph (241 km/h) – compared to 200 pounds of lift in a Camaro SS – which was offset by an increase of only 40 counts of additional aerodynamic drag.

“From the driver’s seat, the added downforce makes a huge change in the feel, and responsiveness of the ZL1 at high speeds,” said Oppenheiser. “One of the best examples of how aerodynamics improved the performance of the ZL1 is the ‘Fuchsröhre,’ or Foxhole at the Nürburgring. In the ZL1, you can take that sweeping left-hand corner flat-out in fifth gear – nearly 160 mph (257 km/h). That’s a great testament to the confidence-inspiring stability and control the aerodynamic design helps give the Camaro ZL1.”

Seven elements contribute to the downforce of the ZL1:

1. Front fascia – The front fascia channels air for engine and brake cooling. The lower opening is larger than in a Camaro SS, providing greater airflow to the engine’s intercooler heat exchanger. Even the grille “fins” were shaped for optimal airflow. The corners of the front fascia, too, were reshaped to minimize lift, while the brake-cooling ducts in the outer corners of the lower grille opening provide a direct, high-flow path to the brake rotors. Cooling the brakes helps extend their life, particularly n the race track.

2. Hood – The ZL1’s hood has a vented, carbon fiber insert, contributing to both engine cooling and aerodynamic downforce. With traditional sealed hoods, air trapped in the engine bay creates lift at the front axle. With the ZL1, the specially shaped vents draw air up through the engine bay – allowing a significant volume of air flow while keeping the front tires firmly connected to the pavement.

3. Front splitter – Instead of a traditional front air dam, the ZL1 incorporates a racing-style splitter to help create downforce. Unlike some competitors’ vehicles that come with an add-on splitter, the ZL1’s does not have to be installed at the track – it is installed at the factory, and is designed with enough ground clearance for all driving conditions.

4. Front tire deflectors – The deflectors push airflow around the rotating wheels and tires more efficiently, reducing lift and drag. And by using deflectors in place of a traditional air dam, the downforce is less sensitive to pitch changes, making the ZL1 feel more stable at high speeds.

5. Belly pans – The ZL1 has two of them: one beneath the engine cradle and one at the rear of the engine assembly, just in front of the transmission. Both extend the width of the chassis out to the wheelhouse opening, to minimize airflow turbulence under the car. NACA-style ducts are incorporated into the rear belly pan for transmission cooling.

6. Rocker panels – Although subtle in appearance, the carefully shaped rocker panels help reduce lift and drag, while also contributing to stability during high cross winds. They also provide stone protection with the ZL1’s wider tires.

7. Rear spoiler – One of the most dramatic aero enhancements comes with the ZL1’s rear spoiler, which contributes approximately 150 pounds of down force at the cost of only 1 count of drag. It is taller and wider than the Camaro SS spoiler and incorporates the center high-mounted stop lamp.

 

Supercharged LSA powertrain

Supporting the dynamic track and street performance of the ZL1 is the LSA 6.2L supercharged engine, which is rated at 580 horsepower (432kW) and 556 lb.-ft. of torque (754 Nm), with specific features for the Camaro.

The all-aluminum engine is part of GM’s legendary small-block engine family. For a solid foundation, the engine’s bottom end uses six-bolt main bearing caps that clamp and lock in the forged steel crankshaft to a deep-skirt cylinder block. Additional features include:

  • Balanced, lightweight reciprocating assembly
  • High-strength hypereutectic pistons
  • Sixth-generation Eaton supercharger with four-lobe rotors
  • Piston oil squirters.

A 1.9L Roots-style blower uses an efficient four-lobe rotor set and compact intercooler to deliver boosted air into the high-flow cylinder heads. The engine also draws its breath through a unique induction system, with a low-restriction air filter, dual inlet paths and enhanced airflow through the supercharger housing.

Because the Camaro ZL1 uses electric power steering, the engine does not incorporate a conventional hydraulic power steering pump on its accessory drive system. This enhances performance, because no engine power is used to turn a steering pump pulley.

The ZL1 is offered with a six-speed manual or automatic transmission. The Tremec TR6060 “MG9” manual features 30 percent more torque capacity than in the Camaro SS. The higher torque capacity results from a strengthened output shaft, high-strength rear housing, and additional roller bearing. The MG9 has also been tuned for improved shift feel, with a dual-mass flywheel, twin-disc clutch, and triple synchros for smooth, precise shifts.

Similarly, the Hydra-Matic 6L90 automatic has been strengthened to handle the torque and horsepower produced by the 6.2L supercharged small-block. It features a strengthened input gearset with two additional pinion gears, additional clutch plate, and a strengthened output shaft and gearset. To make the ZL1 perform equally well on street and track, the 6L90 features three distinct drive modes:

Supercar Performance

The heart of the Camaro ZL1 is a supercharged 6.2L engine is SAE-rated at 580 horsepower (432 kW) and 556 lb.-ft. of torque (754 Nm) – making it the most-powerful production Camaro ever.

The LSA features a Roots-style blower with an efficient four-lobe rotor set and compact intercooler The ZL1 also features a standard dual-mode exhaust system, with vacuum-actuated valves in the exhaust pipes for a refined exhaust note at low speeds as well as a free-flowing system for peak performance.

Power is delivered to the rear wheels through either a six-speed manual or automatic transmission. With either transmission, the Camaro ZL1 delivers impressive performance:

“With 0 to 60 taking less than four seconds, and a top speed in excess of 180 mph, the power and acceleration of the Camaro ZL1 rivals many supercars,” said Al Oppenheiser, Camaro chief engineer. “And, horsepower is only half of the story, as the most significant measurement of the ZL1’s potential is lapping the Nurburgring in 7:41.27. That is a great testament to the power, braking, grip, and balance of the Camaro ZL1, and to the well-rounded performance of the ZL1 that sets the bar for the sports-car segment.”  

Exclusive, track-capable technologies

To deliver that well-rounded performance, the Camaro ZL1 comes standard with several track-capable technologies that are exclusive to the segment.

For example, the Camaro ZL1 is the first sports car to feature the third-generation of Magnetic Ride. This advanced suspension system employs valve-less damping and Magneto-Rheological (MR) fluid technology to varies the suspension firmness to match the road and driving conditions.

“Traditional suspension systems at some point compromise ride quality for road-holding grip and body control,” said Oppenheiser. “With Magnetic Ride Control, we can offer customers the best of both worlds: A comfortable ride that makes the ZL1 appropriate as a daily driver and the incredibly precise body control that makes the ZL1 so enjoyable on the track.”

Also standard on the Camaro ZL1 is Performance Traction Management, which integrates magnetic ride control, launch control, traction control, electronic stability control and electric power steering response to enhance performance.  The technology was first introduced on the Corvette ZR1. With Performance Traction Management, the launch control feature (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. Similarly, on a road course, the driver can apply full throttle when exiting a corner and Performance Traction Management will automatically manage acceleration dynamics to maximize exit speed based on available traction.

In addition, the Camaro ZL1 has been engineered to be track-capable from the factory, including a rear-differential cooler, an integrated engine- and transmission-oil cooler, and brake-cooling ducts as standard equipment. As such, the ZL1 offers many technologies and features not available on the 2012 Ford Shelby GT500:
