Camaro ZL1: Most Powerful Chevrolet Convertible Ever
Chevrolet announced today the brand's most-powerful convertible ever – the 2013 Camaro ZL1 – will debut at the Los Angeles Auto Show next month. When it goes on sale in late 2012, it will deliver more performance and technology than many exotic cars and ultra-luxury convertibles.
'The Camaro ZL1 convertible will be one of the most powerful and most capable, convertibles available at any price,' said Al Oppenheiser, Camaro chief engineer. 'This is a car that is guaranteed to put a smile on your face every time you drop the top – or hit the gas.'
Like the coupe, the Camaro ZL1 convertible features a supercharged 6.2L 'LSA' engine, SAE-rated at 580 horsepower (432 kW) and 556 lb.-ft. of torque (754 Nm). That's enough to exceed the output of 2+2 convertibles of many performance icons, including:
• 2012 Aston Martin DB9 Volante – 470 hp / 443 lb.-ft.
• 2012 Mercedes SL63 AMG – 518 hp / 465 lb.-ft.
• 2011 Porsche 911 Turbo S – 530 hp / 516 lb.-ft.
• 2011 Ford Shelby GT500 – 550 hp / 510 lb.-ft.
The Camaro ZL1 convertible's power is complemented by advanced powertrain and chassis technologies designed to deliver exceptional performance on the road or track. In fact, it's the same balance of acceleration, handling and ride quality that enabled a Camaro ZL1 coupe recently to lap the Nürburgring's Nordschleife course in 7:41.27 minutes.
From Day One, the architecture for the fifth-generation Camaro was designed to accommodate a convertible model, which gives the ZL1 convertible coupe-like driving dynamics. Four strategic reinforcements enhance the already-stiff body structure to quell the cowl and steering wheel shake common in convertibles. They include:
• A tower-to-tower brace under the hood
• A transmission support reinforcement brace
• Únderbody tunnel brace
• Front 'X' brace and stiffer cradle as well as rear underbody 'V' braces.

Engine : 6.2 L., 8-cylinder
Power: 550 hp
Torque: 550 ft-lbs
Additional structural reinforcements in the ZL1 convertible are designed to improve noise and vibration characteristics, while also reducing unwanted ride and body motions. They include a hydroformed tube in the A-pillars, an inner reinforcement bracket in the windshield header, a reinforced front hinge pillar and reinforcements inside the rockers.
The suspension of the ZL1 convertible uses the third-generation of Magnetic Ride. New, twin-wire/dual-coil dampers at all four corners enable faster response, with damping levels now adjusted up to 1,000 times per second – about one adjustment per inch of vehicle travel at 60 mph – making the system exceptionally responsive to changing driving and road conditions.
The Camaro ZL1 convertible will also offer Performance Traction Management as standard equipment, which is exclusive to General Motors. First introduced on the Corvette ZR1, it is an advanced system that integrates magnetic ride control, launch control, traction control and electronic stability control, to enhance both launch-acceleration performance and corning.
The result is a convertible designed to preserve nearly all the acceleration, road-holding and performance capabilities of the Camaro ZL1 coupe, which goes on sale in early 2012.
The 2012 Chevrolet Camaro ZL1 Coupe accelerates from 0 to 60 mph in 3.9 seconds and can reach a top speed of 184 mph. Starting at $54,995, including Performance Traction Management and Magnetic Ride suspension, the ZL1 delivers supercar levels of performance and technology for the price of a sports car.
'From the original Camaro to the current Corvette ZR1, Chevrolet has a long history of delivering world-class cars that outperformed competitors at several times the price,' said Chris Perry, vice president, Global Chevrolet Marketing. 'The ZL1 is no exception. There are very few cars at any price that can match the power, features, and track-capability of the Camaro ZL1.'
For the $54,995 price, including a $900 delivery fee, the ZL1 compares favorably to much more expensive cars: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. (posted on conceptcarz.com)
Additional features and options
'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.
The interior of the Camaro ZL1 features standard leather seating surfaces with suede microfiber inserts and heated, powered-adjustable front seats. Standard technologies include a nine-speaker Boston Acoustics® audio system; ÚSB and Bluetooth connectivity; and rear-park assist with a rear-view camera display integrated in the center rear-view mirror.
The Camaro ZL1 is available with six options:
• Six-speed automatic transmission with TapShift controls is $1,185
• 20-inch, bright aluminum wheel package is $470
• Power sunroof is $900
• Stripe package is $470
• Exposed-weave carbon fiber hood insert is $600
• The suede package, including suede microfiber accents on the steering wheel, shift knob, and shift boot is $500
The Camaro ZL1 Coupe will go on sale in the spring of 2012, as a 2012 model. The Camaro ZL1 Convertible will go on sale in the summer of 2012, as a 2013 model. Pricing for the Camaro ZL1 Convertible will be announced later.Source - Chevrolet
