Corvette
Marks 60 Years of Performance with 427 Convertible

January 12, 2012
– Chevrolet today unveiled the 2013 Corvette 427
Convertible Collector Edition – the fastest, most capable
convertible in Corvette’s history – as well as a 60th
Anniversary Package that will be available on all 2013
Corvette models.
“The 2013 model year
will be historic for Corvette, marking its 60th Anniversary
and the final year for the current ‘C6’ generation,” said
Chris Perry, vice president, Global Marketing and Strategy
for Chevrolet. “We couldn’t think of a more fitting way to
celebrate these milestones than bringing back one of the
most-coveted combinations in the brand’s history – the
Corvette convertible and a 427 cubic-inch engine.”
The 60th Anniversary
Package and 427 Convertible will make their public debut at
the Barrett Jackson collector car auction in Scottsdale,
Ariz., on Jan 21, and will arrive at U.S. Chevrolet dealers
early this summer.
Corvette 427
Convertible Collector Edition
The Corvette 427
Convertible blends elements of the Z06 and ZR1 models to
create the fastest and most-capable convertible in
Corvette’s history.
Its heart is the
427-cubic-inch (7.0L) LS7 engine from the Corvette Z06.
Rated at 505 horsepower (377 kW) and 470 lb.-ft. of torque
(637 Nm), it is the most powerful engine ever installed in a
production Corvette convertible – and, like the Z06, the 427
Convertible is only available with a six-speed manual
transmission.
The LS7 was
co-developed with the Corvette Le Mans-winning GT1 engine
and features lightweight titanium connecting rods and intake
valves, as well as racing-inspired high-flow cylinder heads
and a dry-sump oiling system. It is assembled by hand at
GM’s Performance Build Center, where customers who purchase
the 427 Convertible Collector Edition can purchase the
Corvette Build Experience option and assemble the engine
that will power their new car.
Supporting performance
elements in the Corvette 427 Convertible include the
driveline and rear axle system from the Corvette Z06, a
rear-mounted battery and standard Magnetic Selective Ride
Control. The standard 19-inch front and 20-inch rear wheels
are wrapped in ZR1-style Michelin PS2 tires. Lightweight
machine-face Cup wheels – introduced on the 2012 Corvette
Z06 with Z07 and Corvette ZR1 with PDE performance packages
– come standard and include unique gray-painted pockets.
Black Cup wheels or chrome ZR1-style wheels are also
available.
The 427 Convertible
also features several carbon-fiber components that help
reduce weight, including:
-
Carbon fiber
raised hood (introduced on the 2011 Z06 Carbon Edition)
-
Carbon fiber
Z06-style fenders
-
Carbon fiber floor
panels
-
The “CFZ” carbon
fiber front splitter and rocker panels are optional on
the 427 Convertible, and included with the 60th
Anniversary package
The weight reduction
brings the 427 Convertible’s curb weight to 3,355 pounds
(1,522 kg). Combined with its 505-horsepower LS7 engine, it
gives the 427 Convertible a power-to-weight ratio of 6.64 –
or one horsepower for every 6.64 pounds of vehicle mass.
That’s better than:
-
Porsche 911 Turbo
S Cabriolet – 6.90
-
Audi R8 5.2 RSI
Spyder – 7.58
-
Aston Martin DBS
Volante Convertible – 7.82
-
Ferrari California
Convertible – 8.31
The combination of low
mass and high output will make the 427 Convertible one of
the fastest convertibles in the world, delivering estimated
0-60 performance of 3.8 seconds, quarter-mile performance of
11.8 seconds, lateral acceleration of 1.04 g and a top speed
of more than 190 mph.
The 427 Convertible is
available in 2LT, 3LT and 4LT trim levels and will carry a
unique vehicle identification number sequence, similar to
the Corvette ZR1.
Corvette 60th
Anniversary Package
All 2013 Corvette
models, including the 427 Convertible, will be available
with a 60th Anniversary Package, featuring an Arctic White
exterior with a Blue Diamond leather-wrapped interior with
suede accents. Convertible models will have a blue top.
Additional content
includes a ZR1-style rear spoiler, special badging,
gray-painted brake calipers and the “60th” logo on the wheel
center caps, steering wheel and seat headrests. An optional
graphics package adds full-length racing stripes in Pearl
Silver Blue, including a tonal stripe stitched into the
convertible top, extending the graphic theme over the roof.
For 2013, all
Corvettes will feature 60th Anniversary badges on the
fascias and the “waterfall” panel on convertible models, as
well as 60th logos in the instrument panel gauge cluster and
on the sill plates.

Charity Auction at
Barrett-Jackson Scottsdale
The first Corvette 427
Convertible offered to the public will go to the highest
bidder at the
Barrett-Jackson
Scottsdale collector car auction, on Saturday, Jan. 21.
Proceeds from the sale will benefit the
Drive to End Hunger
food relief program.
Chevrolet and Hendrick
Motorsports are teaming up for the auction, including
Hendrick team driver and four-time NASCAR Sprint Cup
Champion Jeff Gordon. Team owner Rick Hendrick helped launch
the Drive to End Hunger program with AARP and the AARP
Foundation.
The Drive to End
Hunger is part of a multi-year sponsorship for Gordon’s No.
24 Chevrolet. It calls on racing fans, corporations and
charitable organizations to raise money, build awareness,
and engage Americans who face the threat of hunger.
A legacy of
427-powered Corvettes
Early 427-powered
Corvettes, particularly convertibles, offered from 1966 to
1969 are some of the most-coveted and collectable Corvettes
ever produced.
The first 427-powered
Corvette rolled off the assembly line for the 1966 model
year. Two performance levels of the 427 were initially
offered – an “L30” version rated at 390 horsepower and the
“L72,” which cranked out 425 horsepower. Both were rated at
460 lb-ft. of torque.
The range of 427
engines grew in 1967, with the addition of the “L71” and
“L88” options. The L71 added a unique triple-carburetor
induction system that helped boost output to 435 horsepower.
Known to collectors as “427/435” cars, these ’67 models –
especially the convertibles – are especially sought-after
collector cars.
The “L88” delivered
430-horsepower (with a single four-barrel carburetor) thanks
to racing-tuned aluminum heads. Intended for customers who
would immediately transform their new Corvette into a race
car, the L88 was installed in just 216 production Corvettes
between 1967 and 1969.
In 1969, a special
“L89” 427 engine combined the L71’s induction system with
the L88’s aluminum heads, offering maximum horsepower with
an approximately 100-pound weight advantage over the
standard iron heads. Also in 1969, Chevrolet built two “ZL1”
427 Corvette coupes. The ZL1 engine was essentially an
all-aluminum version of the L88, with the aluminum cylinder
block and heads offering a tremendous weight advantage for
racing. More of the engines were sold as crate engines to
racers.
By 1970, the big-block
engine grew to 454 cubic inches, just as the trend in
high-compression, high-performance engines was beginning to
wane. The four-year run of 427 Corvettes was already
established as the golden era of performance
Commemorative
Collector Edition and Anniversary Edition models
Rare and
low-production examples of the Corvette have been around
since its 1953 introduction, but Chevrolet didn’t begin
building commemorative models until 1978, when the 25th
Anniversary model – also known as the Silver Anniversary
Corvette – was offered. The Corvette was in its third
generation then and at the close of that epoch in 1982, a
Collectors Edition was offered, as well.
Those special models
launched what has become a tradition for the Chevrolet
Corvette, which has offered milestone anniversary and
generational collector-edition models ever since. The 2013
Corvette 427 Convertible represents the first time a
Collector Edition and Anniversary Edition are being offered
in the same year – and available on the same car.
Below is a list of the
Collector Edition and Anniversary Edition models, as well as
