1986 C4 Corvette

• One new body style and an engineering development were the highlights of 1986.
• The Corvette line added a convertible during the model year, the first since 1975.
• A computerized anti-lock braking system (ABS) was made standard.
• It was based on a Bosch ABS II design.
• During hard braking, the system detected any wheel that was about to lock up, then altered braking pressure, in a pulsating action, to prevent lock up from happening.
• Drivers could feel the pulses in the pedal.
• This safety innovation helped the driver to maintain traction and keep the car under directional control without skidding, even on slick and slippery surfaces.
• Corvette's engine was the same 350-cid (5.7-liter) 230-hp tuned-port-injected V-8 as 1985, but with centrally-positioned copper-core spark plugs.
• New aluminum cylinder heads had sintered metal valve seats and increased intake port flow, plus a higher (9.5:1) compression ratio.
• The engine had an aluminum intake manifold with tuned runners, magnesium rocker covers and an outside-air induction system.
• Both four-plus-three manual and four-speed overdrive automatic transmissions were available, now with an upshift indicator light on the instrument cluster.
• Three monolith catalytic converters in a new dual-exhaust system kept emissions down during warm up.
• Cast alloy wheels gained a new raised hub emblem and a brushed-aluminum look.
• The instrument cluster was tilted to cut glare.
• The sport seat from 1985 was made standard, with leather optional.
• Electronic air conditioning, announced earlier, arrived as a late option.
• Otherwise, standard equipment was similar to 1985.
• A new electronic Vehicle Anti-Theft System (VATS) was also made standard.
• A small electrically-coded pellet was embedded in the ignition key, while a decoder was hidden in the car.
• When the key was placed in the ignition, its resistance code was "read."
• Unless that code was compatible, the starter relay wouldn't close and the Electronic Control Module wouldn't activate the fuel injectors.
• Corvette's back end held four round recessed lenses, with "CORVETTE" block letters in the center.
• The license plate sat in a recessed housing.
• Cloth seats had lateral support and back-angle adjustments.
• The new convertible (a.k.a. "roadster") had a manual top with a velour inner liner.
• The yellow console button that ordinarily controlled Corvette's hatch release instead opened a fiberglass panel behind the seats to reveal the storage area for the top.
• Size 16 x 8-1/2 inch cast-alloy aluminum wheels held unidirectional P255/50VR-16 Goodyear Eagle GT SBR tires.
