context_page_description: The fifth-generation Chevrolet Camaro is a pony car that was manufactured by American automobile manufacturer Chevrolet from 2010 to 2015 model years. It is the fifth distinct generation of the muscle/pony car to be produced since its original introduction in 1967. Production of the fifth generation model began on March 16, 2009 after several years on hiatus since the previous generation's production ended in 2002 and went on sale to the public in April 2009 for the 2010 model year.
context_section_description: Unveiled at the 2011 Chicago Auto Show, the ZL1 is a high-performance variant of the Camaro SS. At least 30 percent of the parts on the ZL1 are exclusive to the model.
  The car features a 6,162 cc (6.2 L; 376.0 cu in) LSA V8 engine with a 1.9 L (120 cu in) supercharger which produced a maximum boost pressure of 7 psi (0.48 bar). The engine has a power output of 580 hp (588 PS; 433 kW) at 6,000 rpm and 556 lb⋅ft (754 N⋅m) of torque at 4,200 rpm. Power is delivered to the rear wheels by either a six-speed manual (TR-6060) or a 6L90 automatic transmission. The manual transmission has a stronger outputshaft, a more robust rear housing and an additional mainshaft roller bearing to provide 30-percent more torque capacity than the automatic transmission used in the Camaro SS. To improve shift quality, there are triple synchros in some gears and a revised linkage. A new dual-mass flywheel is bolted to a high-capacity twin-disc clutch. The automatic transmission has additional clutch plates, a strengthened output shaft and is programmed with three operating modes (Drive/Sport/Manual).
  The ZL1's power is complemented by exclusive performance technologies, including the third generation of Magnetic ride suspension and Performance Traction Management. Brembo supplied the braking system having six piston calipers at the front and four piston calipers at the rear. A duct system delivers air from the grille to the hard-working rotors. The 20-inch forged-aluminum wheels are fitted with second-generation Goodyear Eagle F1 Supercar tires (size 285/35ZR-20 at the front and 305/35ZR-20 at the back). Damping is provided by Magnetic Ride Control units. This system can sense the need for a damping correction 1,000 times per second and make that change in only five milliseconds. The Performance Traction Management (PTM) system was originally engineered for the Corvette ZR1. In addition to modulating engine torque for optimum launch performance in manual-equipped ZL1s, PTM also varies the traction control and suspension damping as needed. The five available modes are for wet, dry, sport with or without stability control and race-driving conditions.
  Additional track-ready features standard on the Camaro ZL1 include coolers for the engine, transmission and rear differential, cooling ducts for the Brembo brakes, and a high-performance fuel system delivering fuel to the LSA engine under any performance-driving condition. The ZL1's rear axle includes a high-capacity cast-iron-case differential, large asymmetrical half shafts, and extra-heavy-duty universal joints. To keep the lubricant temperature in line, there's an oil-to-oil heat exchanger built into the bottom of the differential. Transmission fluid circulates through that heat exchanger and through the radiator to drop operating temps by more than 100 °F (38 °C). In addition, the engine is fitted with the same oil-to-coolant heat exchanger used in the Corvette ZR1. The ZL1 has a deeper oil pan, a longer pickup, and a higher-capacity pump than the SS.
