Chevrolet Camaro Coupe 2001

##title##
The fourth-generation Chevrolet Camaro debuted for the 1993 model year on an updated F-body platform. It would retain the same characteristic since the first-generation's introduction back in 1967; 2-doors, 2+2 seating, available as a coupe (with optional T-top roof) or convertible, rear-wheel drive, and a choice of V6 and V8 powerplants. The 1998 model year was refreshed and revised with both exterior and engine changes. The fourth-gen Camaro would last up through the 2002 model year when General Motors discontinued production due to slow sales, a deteriorated sports coupe market, and plant overcapacity.

1993 was the debut year for the fourth generation Camaro, and production continued until 2002. Production was moved from GM's Van Nuys, California, assembly plant to Sainte-Thérèse, Quebec, Canada in 1993. The new design incorporated sheet moulding compound (SMC) made from chopped fiberglass and polyester resin for the roof, hatch, doors, and spoiler. Both the front and rear suspension design was improved. Base Camaros were powered by a 160 hp (119 kW) 3.4 L V6. The 1993 Camaro also featured the LT1 V8 engine with 275 hp (205 kW) and 325 lb·ft (441 N·m) torque that had been introduced in the Corvette one year earlier, as well as an optional Borg-Warner six-speed manual transmission when ordered with the V8. The Camaro was the first of many vehicles to use this gearbox. In 1993, the Camaro Z28 was selected as the official pace car for the Indianapolis 500. A "pace car edition" as a $995 option found 633 buyers and featured "Indy 500" identification on black and white body color scheme with multicolored pinstriping and white painted roadwheels.

Several changes occurred for 1994. The 4L60 automatic transmission was replaced with the more dependable and better built 4L60E that included electronic controls, and was also used in Chevrolet trucks and Tahoe of this era. Accordingly, the car's on-board computer was modified from dealing only with the engine as in 1993 and earlier, to controlling both the engine and transmission on automatic models.

The computer, in 1993, was run via Speed Density, which measured engine speed (RPM) and load (MAP in kPa) to compute airflow requirements and then use that against the VE table to get the proper fueling for conditions. An IAT (Intake Air Temperature sensor) was also used as air density changes with temperature. In 1994 however, the computer logic was changed over to a Mass Air Flow system. This system uses a Mass Air Flow Sensor placed in front of the throttle body to measure the incoming airflow into the motor. This is measured by using a heated wire in the sensor in the airstream path which has heat pulled away from it via the incoming air. This reduced heat is converted into a voltage signal which is sent to the PCM which then converts that voltage signal in to mass flow. The computer uses engine sensors to judge engine conditions and provide the proper fueling off of this mass airflow reading. This was one of the main differences between the 93 and 94+ F-Body cars (and 92-93 Vette's compared to 94-96) and one of the items that makes a 93 model unique. Another prominent difference between the "Speed Density" 93's and the 94+ cars is how the programming (or custom tuning) of the computer takes place. In 1993, the stock computer uses a Memcal chip, which is a removable chip from the factory computer. Contained in this chip is the program for the car to run. In the 1994+ cars, this was swapped to a non-removable reflashable chip, which could be reprogrammed via the Auto Line Data Link, or ALDL, located underneath the driver side of the dash, next to the center console. Many people view this a more user-friendly and easier way to tune the vehicle.

Dashboard gauge graphics were changed from yellow to white. There was also a spot in the gauge cluster that says ASR off. GM had every intent to put ASR or Acceleration Slip Regulation (Pontiac called it "TCS") in the 94 F-bodys, but it never made it into production until 95. The front brakes were revised on the Z28 model. Cooling fans were changed mid-year from a parallel to a series setup. On low both fans operated on 6V, but on high both operated on 12V. The V-8 LT1 equipped Camaro Z28s did 0-60 in 5.7 seconds and quarter mile times of 14.2.

In 1995, base Camaros in California were equipped with the 3800 Series II engine for emissions compliance while base Camaros sold elsewhere retained the 3.4 L (207 cu in) engine. This would be the last year the 3.4 L (207 cu in) V6 engine would be available. For the LT1-powered Camaros, the often-problematic Opti-spark distributor was updated to include a vent to remove moisture from the unit. The cam drive system for the distributor was also changed, making "early" & "late" model cams and distributors non-interchangeable. 1995 was also the first year the fourth-generation Camaro had the option of painted side bars and mirrors. Traction control became available as an option on LT1 Camaros, but was installed on the base Camaros. Z28 rooftops, door handles, and mirrors, which were previously only available in black, now had the option to be painted the same as the body color.

1996 saw minor mechanical revisions, as well as small power gains from the new OBD II-compliant engine controls. All base model Camaros were now equipped with the 3800 series II. V8 models still came with the 5.7L LT1 engine. The dual catalytic converters required by OBD-II resulted in lower restriction and a mild power boost to 285 hp (213 kW) and 325 lb·ft (441 N·m) of torque. Two option packages also returned: the RS (last seen in 1992), an appearance option for the V6 model, and the SS (last seen in 1972), a performance and appearance package for V8-powered cars. The SS cars were the highest factory performance Camaros offered at the time and included a functioning hood scoop and new five-spoke 17 in (43 cm) x 9 in (23 cm) wheels. The new wheel and tire package on the SS resulted in better handling and braking compared to the Z28. Convertible Super Sport cars however had 16 inch ZR1 style wheels. Also available this year for the V6 model was the Y87 package, which included an Auburn limited-slip differential, better tires, dual exhaust tips, 4-wheel disc brakes, a sportier steering ratio, and more aggressive gear ratio in the differential for automatic equipped cars. Available was a 4-speed automatic transmission or 6-speed manual transmission.
