1990 Chevrolet Corvette ZR-1 �€" LT5 5.7L DOHC 32-Valve V8, ZF
6-Speed Manual, Red over Tan Why This Car Is Special The 1990
Chevrolet Corvette ZR-1 was not a trim package bolted onto a
standard Corvette. It was a ground-up engineering effort developed
in partnership with Lotus Engineering �€" then owned by General
Motors �€" and built around an entirely new engine that Chevrolet
could not produce in-house. The result was the LT5, a 5.7-liter
dual-overhead-cam V8 with 32 valves and 375 horsepower, assembled
by hand at Mercury Marine's facility in Stillwater, Oklahoma. No
other engine in any American production car at the time came close
to matching it on a technical level. To accommodate the wider LT5,
Chevrolet widened the ZR-1's rear bodywork by approximately three
inches compared to a standard C4 Corvette. This gave the ZR-1 a
distinctive rear stance that is immediately recognizable to anyone
who knows the car. The convex taillights on this car are the
rectangular ZR-1 units, not the round taillights found on base C4s
�€" another distinguishing detail that separates the two cars at a
glance. Chevrolet built just 3,049 Corvette ZR-1s for the 1990
model year, the first full production year of the model. That makes
1990 the highest-volume year of the early ZR-1 run, though
production remained low throughout the car's lifespan from 1990
through 1995. Total ZR-1 production across all six model years was
fewer than 7,000 units. This car carries its original ZR-1 badges,
ZR-1 alloy wheels, and the characteristic wide-body rear treatment
that marks it as genuine. The position in the C4 generation makes
this car particularly interesting from a collector standpoint. The
C4 ran from 1984 through 1996, and the ZR-1 represented its
performance ceiling. Road and Track recorded a 0-60 time of 4.5
seconds and a top speed in excess of 170 miles per hour for the
1990 ZR-1 �€" numbers that genuinely competed with Ferrari and
Porsche at the time. Car and Driver called it the fastest
production car they had ever tested up to that point. Those claims
were not marketing. They were backed up on track. Features List -

Convex rectangular ZR-1 taillights Mechanical The heart of this car
is the LT5 5.7-liter DOHC V8. Four camshafts, 32 valves, and
sequential fuel injection produced 375 horsepower in 1990
specification. The engine was entirely different from anything else
in the Corvette lineup �€" it shared no major components with the
standard L98 V8 that powered base C4 Corvettes of the same era. The
LT5 was designed to breathe, with a high-revving character that was
genuinely foreign to American V8 tradition at the time. Backing the
engine is the ZF 6-speed manual transmission, sourced from ZF
Friedrichshafen in Germany. This is the correct gearbox for the
ZR-1 application �€" it was the only transmission available in the
car, as no automatic was offered. The ZF unit is a robust,
well-regarded gearbox, and finding a ZR-1 with an intact,
functioning manual drivetrain is an increasingly important
consideration as these cars age. The photographs confirm the
presence of the ZF transmission visible from underneath the car,
along with the dual exhaust system that terminates in the ZR-1's
signature quad-tip configuration at the rear. The undercarriage
photos show surface rust typical of a driven car of this age, with
no visible structural concerns. The suspension components,
including the distinctive yellow Bilstein shock absorbers visible
in the wheel well shots, appear present and intact. The C4 Z
