Engine/technical
The AE86 was available with a fuel-injected 4-cylinder twin-cam 1587 cc 4A-GE engine in Japan and Europe which was also used in the first-generation Toyota MR2 (AW11)And the facelift Toyota Celica GT-R and GT Carina (Japan only). This engine had a maximum gross power output of 130 PS (128 bhp; 96 kW) and 110 lb·ft (150 N·m) of torque in standard form, though it was later down-rated to 120 PS (118 bhp; 88 kW) and 105 lb·ft (142 N·m) in net output.[3][4] The AE86 came with a 5-speed manual gearbox, and later came with the option of an automatic. The 4A-GE engines used in the AE86 and AW11 were equipped with T-VIS (Toyota Variable Intake System). The AE86 had an optional LSD.[3]

In North America, a modified 4A-GEC engine was used to comply with California emissions regulations. Power was rated at 112 bhp (84 kW), and 96 lb·ft (136 Nm) of torque.[3]

The AE86 used ventilated disc brakes. The car was equipped with a MacPherson strut style independent suspension at the front and a four-link live axle with coil springs for the rear. Stabilizer bars were present at both ends.[3]

Higher- spec AE86 models known as the GTS featured the DOHC 4AGE, 4 wheel disc brakes, color matched bumpers, front lower bumper surround had a much more sporty and pronounced lip, door panels were moulded, tachometer redline is around 7,500, wrapped steering wheel, seats had leather wrapped tops ( front seats are completely different from SR5), optional LSD, and aluminium wheels, chassis code in the VIN is AE88 (for North American market cars).

Lower-spec American AE86 SR5 models used the 1587 cc 4A-C SOHC unit, The SR5 rear end was a non LSD with drum brakes. The SR5 model also had a softer suspension, and small styling and interior changes such as seats, gauge cluster, door panels, un-painted front and rear bumpers, and the lower part of the front bumper surround is shorter and flat, and its chassis code in the vin differs as well being AE86 for the SR5 model (for North American market cars)

Models equipped with the 4A-GE engine received a 6.7" rear differential, while 4A-U, and 4A-C models received a smaller, weaker, 6.38" rear differential.

The AE86 SR5 (4A-C equipped) had an optional automatic transmission, though the GT-S model (with the 4A-GE DOHC engine) only came with a standard 5-speed manual gearbox.

One of the staff who was behind the car's engineering work was Nobuaki Katayama, who would later head the company's motorsport department and who would become chief engineer of the Altezza project a decade later.[citation needed] An article in Car Magazine in April 1999, stated he has a photo of an AE86 hung in his office.
