Camaro ZL1 Delivers 580 Horsepower and Exclusive Technologies
The 2012 Chevrolet Camaro ZL1's 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 ZL1's outstanding power is complemented by advanced powertrain and chassis technologies, including exclusive Performance Traction Management and third-generation Magnetic Ride Control.
"The Camaro ZL1 delivers supercar performance and technology in the sports-car segment," said Al Oppenheiser, Camaro chief engineer. "For sheer power, the ZL1 delivers more horsepower than a Ferrari 458, more torque than an Aston Martin DB9 V12, and a better power-to-weight ratio than a Porsche 911 Carrera GTS.
"The Camaro ZL1 also features exclusive chassis and traction technologies," Oppenheiser said, "to offer the best of all worlds -- including balanced handling for the track, acceleration for a drag strip, and the comfort of a daily driver."
The most-powerful production Camaro ever
The 2012 Camaro ZL1's surpasses the advertised power of the legendary 1969 Camaro ZL1's 427 cubic-inch big block by more than 150 horsepower (112 kW) -- while meeting modern emissions requirements. And, the new ZL1 is backed by General Motors' five-year / 100,000-mile powertrain warranty.
"The torque is going to make the ZL1 a car you won't want to get out of," said John Rydzewski, assistant chief engineer for small block engines. "Not only will the ZL1 have more power and torque than the competition, we're making it available with an optional automatic transmission, to appeal to a wider group of sports car enthusiasts."
The all-aluminum LSA supercharged V-8 is part of GM's legendary small-block engine family. For a solid foundation, the engine's lower end uses six-bolt main bearing caps that clamp and lock in the forged steel crankshaft to the deep-skirt block. Its 1.9L Roots-style blower uses an efficient four-lob rotor set and compact Intercooler to deliver Boosted air into the high-flow cylinder heads.
For the Camaro ZL1, the LSA features a unique induction system, with a lower-restriction air filter, dual inlet paths, and improved airflow through the Supercharger housing. Other changes include a higher-efficiency SuperchargerIntercooler and electric power steering system, which consumes less engine power than hydraulic-steering systems.
The ZL1 will be offered with either a six-speed manual or automatic transmission. The Tremec TR-6060 "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.

2012 Camaro ZL1 Features Technically Advanced 6.2L Supercharged V-8
CHICAGO -- The all-new, 2012 Chevrolet Camaro ZL1 is powered by the LSA 6.2L supercharged V-8 engine that produces an estimated 550 horsepower (410 kW) and 550 lb.-ft. of torque (745 Nm).
The LSA is the most powerful engine ever offered in a Camaro, eclipsing even the original ZL1 engine from 1969 that inspired the name of the new, maximum-performance model. Built on GM's legendary small-block V-8 architecture, it features an intercooled Supercharger system, premium heat-resistant aluminum cylinder heads and other details designed to ensure its exceptional performance is delivered with smoothness and refinement.
"The LSA is the ultimate engine for the ultimate Camaro," said John Rydzewski, assistant chief engineer for small-block engines. "It has a broad power band that matches the Camaro ZL1's performance capabilities at every notch on the tachometer."
Components and design elements that contribute to the LSA's performance include:
■Balanced, lightweight reciprocating assembly
■High-strength hypereutectic pistons
■Sixth-generation Eaton Supercharger with four-lobe rotors
■Center-feed fuel system
■Piston oil squirters.
A Tremec TR6060 six-speed manual transmission is matched with the LSA. It uses a 240-mm dual-mass flywheel matched with a 240-mm twin-disc clutch system to provide excellent shift smoothness.
Compared to the Cadillac application, the LSA used in the Camaro features the following unique components and details:
■Black Intercooler housing with unique heat exchanger and plumbing to accommodate the Camaro engine compartment
■Cast stainless steel Exhaust manifolds for enhanced thermal management
■Camaro-specific oil pan
■Revised accessory drive with unique alternator and air conditioning compressor
■Idler pulley in place of the conventional power steering pump pulley, because of the use of electric power steering
■Special engine cover in red.
Supercharged power delivery
The LSA engine's sixth-generation Eaton Supercharger, with high-helix, four-lobe rotors, enables a broad range of power through the rpm band, giving the engine great low-end torque and excellent horsepower at higher rpm.
"The design of the Supercharger's rotating internal components extends its effective range, giving the engine a wide, flat power band that is usable at all rpm levels," said Rydzewski, assistant chief engineer. "Whether at low speeds or on the highway, the feeling of power is instant, strong and sustained."
Heavy-duty and lightweight reciprocating components support the engine's high-rpm, supercharged performance. The parts are housed in an aluminum cylinder block that features nodular iron, six-bolt main caps. Cast iron cylinder liners -- measuring 4.06 inches (103.25 mm) in bore diameter -- are inserted in the aluminum block and they are finish-bored and honed with a deck plate installed. The deck plate simulates the pressure and minute dimensional variances applied to the block when the cylinder heads are installed, ensuring a higher degree of accuracy that promotes maximum cylinder head sealing, piston ring fit and overall engine performance.
Nestled inside the LSA's deep-skirted cylinder block is a forged steel crankshaft that delivers a 3.62-inch (92 mm) stroke. It features an eight-bolt flange -- the outer face of the crankshaft on which the flywheel is mounted -- that provides enhanced clamping strength. Other non-supercharged GM 6.2L engines have a six-bolt flange. A torsional damper mounted to the front of the crankshaft features a keyway and friction washer, which is designed to support the engine's high loads.
Connected to the crankshaft is a set of lightweight powder-metal connecting rods and hypereutectic pistons, which, when combined with the cylinder heads, delivers a 9.1:1 compression ratio. The alloy of the pistons was selected for its strength and heat resistance properties, while the cast design provides inherent quieting advantages over other piston materials, such as forged aluminum.
High-flow cylinder heads based on GM's proven L92 design channel incoming air into the combustion chambers. They are made with a premium A356T6 alloy that offers excellent heat resistance, particularly in the bridge area of the cylinder head, between the intake and Exhaust valves. Additionally, each head is manufactured with a roto-casting method.
2012 Chevrolet Camaro ZL1 with Launch Control
While attending a press preview of the 2012 Chevrolet Camaro ZL1 at Virginia International Raceway, Vehix's Contributing Editor, Thom Blackett, grabbed this short clip demonstrating the car's launch control feature.
The idea is to maximize off-the-line grip, something that can go up in smoke with a 580-horsepower muscle car. To activate the system, tap the traction control button (located forward of the gear shift) twice. At that point, plant the throttle and the engine rpm will be limited to about 4,000 (varies slightly depending on weather conditions). Drop the clutch, and you're off.
Even under wet conditions, the 580-hp ZL1 was able to hook up and get moving, rather than sit and spin the rear rubber. And, thanks to a driver who had a little trouble activating the launch control system, we get to hear the supercharged 6.2-liter V8 sing at nearly full throttle.
