2013 Chevrolet Camaro ZL1 Hennessey HPE700 Convertible �€" Serial
Number 25, 700 HP, Dyno Sheet On File Why This Car Is Special The
fifth-generation Camaro ZL1 was already a serious performance car
when it left the factory. Chevrolet built it around the LSA �€" a
6.2-liter supercharged V8 shared with the Cadillac CTS-V �€" rated
at 580 horsepower and 556 lb-ft of torque in stock form. It was the
most powerful production Camaro ever built at that point, and it
came with Brembo brakes, Magnetic Ride Control, and a suspension
tuned with input from the Nurburgring. For 2013, GM added the
convertible body style to the ZL1 lineup, making an already rare
car even harder to find. The ZL1 convertible was produced in
limited numbers relative to the coupe, and buyers who wanted
open-air driving with genuine supercar-level performance had
essentially one choice from Detroit. This particular 2013 Chevrolet
Camaro ZL1 Hennessey HPE700 is not a stock ZL1. It was sent to
Hennessey Performance Engineering in Sealy, Texas, where it
received the HPE700 package �€" a comprehensive engine upgrade that
pushes output to 700 horsepower. This is a numbered build: the dash
plaque reads Serial Number 25, confirming this car's place in the
HPE700 production run. The Hennessey dyno sheet is on file and
transfers with the car, so the horsepower claim is not a sticker
�€" it's a documented result from the chassis dyno. The odometer
shows 28,735 miles, which for a 700-horsepower convertible built in
limited numbers, is a genuinely low-use example. The Hennessey
HPE700 package on the fifth-gen ZL1 typically includes upgraded
supercharger components, ported and polished throttle body,
high-flow fuel injectors, recalibrated engine management, and an
upgraded intercooler system. The result is a car that moves the
stock 580-horsepower baseline to 700 horsepower at the crank, with
corresponding torque increases that make the automatic transmission
feel like it's constantly searching for more road. This car is
paired with the 6-speed automatic, which Hennessey tunes to handle
the added output. Features List - Hennessey HPE700 package, 700 HP,

LSA engine in the 2013 Camaro ZL1 uses a Roots-type 1.9-liter Eaton
supercharger with an integrated intercooler mounted in the intake
manifold valley. From the factory this combination produced 580
horsepower �€" enough to push the fifth-gen ZL1 to a 0-60 time
under four seconds and a quarter mile in the low 12-second range.
The Hennessey HPE700 package builds on that foundation rather than
replacing it, keeping the LSA's proven bottom end and supercharger
architecture while extracting an additional 120 horsepower through
targeted component upgrades and recalibration. The dyno sheet on
file documents the actual output of this specific car, which is a
meaningful piece of provenance �€" it distinguishes this build from
cars that simply wear an HPE badge without supporting paperwork.
The chassis under this 2013 Camaro ZL1 Hennessey is worth examining
